You have been asked to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link? Star Mesh Bus Ring

Mesh Explanation In a mesh topology, each network device is interconnected to all other network nodes. This creates multiple data paths and in the event of a failed link, the data has an alternate route to arrive at its destination. The star topology connects network devices to the network with a single patch cable and the failure of a patch cable will make the connected device unavailable. The bus topology has a single point of failure, if there is a break in the network media, the network will be unavailable. A single break in a physical ring topology will disable the network.

You have implemented an adhoc wireless network that doesn't employ a wireless access point. Every wireless network card can communicate directly with any other wireless network card on the network. What type of physical network topology has been implemented in this type of network? Mesh Ring Star Tree Bus

Mesh Explanation This type of network uses a physical mesh topology. The key characteristics of a mesh topology are: • There's no central connecting point. • Any host can communicate directly with any other host on the network. A mesh network, such as this one, is usually impractical on a wired network. Each host would have to have a separate, dedicated network interface and cable for each host on the network. However, a mesh topology can be implemented with relative ease on a wireless network due to the lack of wires.

Which of the following might you suspect as the cause of the connectivity problems?

Overlapping channels

Which of the following associates a port number with a host on a private network? NAT CIDR PAT VLSM

PAT Explanation Port address translation (PAT) associates a port number with the translated address. Use PAT to allow multiple private hosts to share a single public address. Each private host is associated with a unique port number.Technically speaking, NAT translates one address to another. With only NAT, you would have to have a public address for each private host. NAT would associate a single public address with a single private address. Because virtually all NAT routers perform port address translation, most routers that are configured with NAT are really performing PAT. When you use a NAT router, you are normally using PAT and not just NAT. (NAT is typically used synonymously with PAT.) Classless InterDomain Routing (CIDR) allows for non-default subnet masks (variable length subnet mask or VLSM).

Which of the following protocols has a limit of 15 hops between any two networks? BGP EIGRP OSPF RIP ISIS

RIP Explanation RIP networks are limited in size to a maximum of 15 hops between any two networks. A network with a hop count of 16 indicates an unreachable network. The other routing protocols do not use the hop count as the metric. EIGRP uses bandwidth and delay for the metric. OSPF and ISIS use a relative link cost. BGP uses paths, rules, and polocies for the metric.

What is the main difference between RIP and RIPv2? RIP has a limit of 15 hops, while RIPv2 increases the hop count limit. RIP is a distance vector protocol, while RIPv2 is a link state protocol. RIP is a classful protocol, while RIPv2 is a classless protocol. RIP use the hop count for the metric, while RIPv2 uses a relative link cost.

RIP is a classful protocol, while RIPv2 is a classless protocol. Explanation RIP v1 is a classful protocol, meaning that the subnet mask is not included in routing updates. With RIP, only the default subnet mask is used to identify networks. RIP v2 is a classless protocol, meaning that the subnet mask is included in routing updates. RIPv2 supports variable length subnet masks (VLSM). Both RIP and RIPv1 are distance vector protocols and use the hop count for the metric. RIP and RIPv2 have a limit of 15 hops between any two networks.

Which of the following statements about RIP is true? RIP uses hop counts as the cost metric. RIP is the routing protocol used on the Internet. RIP is suitable for large networks. RIP is a link state routing protocol.

RIP uses hop counts as the cost metric. Explanation RIP is a distance vector routing protocol. As such, it is susceptible to the count-to-infinity problem. RIP uses the hop count as the cost metric. Because it has a limitation of 15 hops in one route, it is not suited for large networks.

Which of the following best describes the purpose of using subnets?

Subnets divide an IP network address into multiple network addresses.

Which of the following best describes the purpose of using subnets? Subnets let you connect a private network to the Internet. Subnets place each device within its own collision domain. Subnets combine multiple IP network addresses into one network address. Subnets divide an IP network address into multiple network addresses.

Subnets divide an IP network address into multiple network addresses. Explanation Subnets divide an IP network address into multiple network addresses. This allows you to have several smaller networks while using only one network address.

You manage a subnet that uses the following subnet address: 198.162.1.0/23. Which of the following best describes how addressing is configured for the subnet? Supernetting Private Subnetting Classful

Supernetting Explanation The subnet address 198.162.1.0/23 is an example of a supernetted address. With supernetting, multiple smaller subnets are combined into a single larger subnet. Supernetting is performed by taking the default subnet mask and making it smaller (using less bits). For this address, the default subnet mask uses 24 bits (255.255.255.0). With supernetting, the mask is altered to use only 23 bits (255.255.254.0) to combine multiple subnets together. Subnetting is the process of dividing a larger network into smaller networks. With the subnet address in this example, a subnetted address would use a larger subnet mask (using more bits). A subnetted address might use 25 bits (255.255.255.128) or more to subdivide the network into multiple smaller subnets. Sometimes the term subnetting can be used to refer to both subnetting and supernetting, but in this example, supernetting better describes what is being done. Classful addressing uses the default subnet mask based on the address class. If classful addressing were used, the subnet would use a 24 bit mask. Private addresses are within the following ranges: • 10.0.0.1 to 10.255.255.254 • 172.16.0.1 to 172.31.255.254 • 192.168.0.1 to 192.168.255.254

Switch & Network interface card Explanation A network interface card and a switch operate at layer 2 (Data Link) of the OSI model. Layer 2 includes protocols that define the MAC address. The MAC address is burned into the network interface card, and a switch uses the MAC address to make forwarding decisions. A hub or a repeater operate at layer 1; they regenerate a signal without looking at layer 2 or layer 3 information. A router operates at layer 3, using the IP address to make forwarding decisions. A firewall operates at layer 3 or higher, using packet or data contents for making filtering decisions.

The number of routers that the packet must go through to reach the destination network. The last router in the path to the destination network. A backup router that is used for forwarding packets addressed to unknown networks.

The first router in the path to the destination network. Explanation The next hop router is the first (or next) router in the path to the destination network. Each router looks at the destination network in the packet, then consults the routing table to identify the next hop router to the destination network. The hop count identifies the number of routers in the path to the destination network. A default gateway router is a router that is used for packets used to external networks. Most routers do not have a default gateway setting, but instead use a default route setting which identifies a next hop router for all unknown networks.

A router is connected to network 192.168.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. The next hop router for network 192.168.3.0 has changed. You need to make the change with the least amount of effort possible. What should you do? Manually reconfigure the default route to point to the new next hop router. Stop and restart the RIP protocol on the router. Wait for convergence to take place. Force RIP to perform an immediate update.

Wait for convergence to take place. Explanation When using a routing protocol, changes in routing information take some time to be propagated to all routers on the network. The term convergence is used to describe the condition when all routers have the same (or correct) routing information. Static routes in the routing table must be updated manually. Restarting RIP might actually increase the time required for changes to be learned. Forcing an update (if the router supports it) is not a requirement as the periodic sharing of routes will eventually update the routing table entry.

You have been tasked with designing a high-speed Ethernet network. Your client's building already has 150 ohm shielded twisted pair wiring installed. Due to budget constraints, they have asked you to reuse the existing wiring instead of installing new fiber optic cabling. Which Ethernet standard could you implement in this situation?

1000BaseCX

You have been tasked with designing a highspeed Ethernet network. Your client's building already has 150ohm shielded twisted pair (STP) wiring installed. Due to budget constraints, they have asked you to reuse the existing wiring instead of installing new fiberoptic cabling. Which Ethernet standard could you implement in this situation? 1000BaseZX 10BaseFL 1000BaseLX 1000BaseCX 1000BaseT 1000BaseSX

1000BaseCX Explanation The 1000BaseCX standard specifies 150ohm STP cabling. The maximum cable length is 25 meters. The 10BaseFL, 1000BaseSX, 1000BaseLX, and 1000BaseZX standards employ fiberoptic cabling. 1000BaseT uses Category 5 UTP instead of STP cabling.

(Choose two.) 1000BaseSX 1000BaseT 10GBaseSR 10BaseFL 1000BaseCX

1000BaseSX 10GBaseSR Explanation 10GBaseSR and 1000BaseSX can operate within these parameters. Both will support segment lengths 300 meters long and operate using full-duplex. 10BaseFL isn't a good choice because its data transmission rate is relatively slow. 1000BaseCX and 1000BaseT both use copper wiring.

Which Gigabit Ethernet standard uses fiberoptic cabling and supports network segments up to a maximum of 550 meters long? 1000BaseT 1000BaseZX 1000BaseCX 1000BaseSX

1000BaseSX Explanation The 1000BaseSX standard uses fiberoptic cable with a maximum segment length of 550 meters. However, to implement segments this long, you must use 50 micron, 500MHz/km fiber optic cable. Other types of cable will shorten the maximum segment length. 1000BaseFX also supports lengths up to 550 meters. 1000BaseFX supports distances up to 10 kilometers. 1000BaseZX has a maximum segment length of up to 100 km. 1000BaseCX and 1000BaseT use copper cabling instead of fiberoptic.

172.16.1.26 2.2.2.2 Explanation A valid IPv4 address consists of 4 8bit (1 byte) numbers separated by periods. For example, 10.0.0.65. Because they are 8 bits long, these numbers are frequently called octets. Even though we typically express these numbers using decimal notation, it's important to remember that these numbers are binary numbers. The lowest value one of these numbers can have is 00000000. The decimal equivalent for this number is simply 0. The highest value one these numbers can take is 11111111. The decimal equivalent of this number is 255. Therefore, in decimal notation, each octet must contain a number between 0 and 255inclusively.

You are planning a network for an educational campus. Due to the size of the buildings and the distance between them, you have elected to use 10BaseFL hubs, cabling, and network interface cards. What is the maximum length for the network cable between a workstation and a hub?

2000 meters

2000 meters Explanation The maximum length for a 10BaseFL network segment is 2000 meters (2 km). Because a 10baseFL network uses a physical star topology, a segment is defined as one of the arms of the star, (between the hub and a host). That means the fiberoptic cable between the hub and a workstation can be up to 2000 meters long. 100BaseFX supports up to 412 meters. 1000BaseSX and 1000BaseLX support up to 550 meters. 100 meters is the maximum twisted pair cable length.

You are configuring the IP address for a host and have been asked to use the address 192.160.99.110/16. What subnet mask value would you use? 255.0.0.0 255.255.0.0 255.255.252.0 255.255.255.0

255.255.0.0 Explanation With CIDR notation, the number of bits in the subnet mask is indicated by the /16 following the IP address. A mask that uses 16 bits is written 255.255.0.0 in decimal format. Each octet in the mask uses 8 bits, so a mask with 16 bits uses two full octets. Use /8 for the mask 255.0.0.0 and /24 for the mask 255.255.255.0. In this example, a /24 mask would be the default subnet mask, but the address is using a nondefault mask of 255.255.0.0.

What is the network address and subnet mask used by APIPA? (Select two.) 255.0.0.0 255.255.255.0 169.0.250.0 255.255.0.0 169.254.0.0 169.255.0.0

A security administrator is conducting a penetration test on a network. She connects a notebook system running Linux to the wireless network and then uses NMAP to probe various network hosts to see which operating system they are running. Which process did the administrator use in the penetration test in this scenario?

Active fingerprinting Active fingerprinting is a form of system enumeration that is designed to gain as much information about a specific computer as possible. It identifies operating systems based upon ICMP message quoting characteristics. Portions of an original ICMP request are repeated (or quoted) within the response, and each operating system quotes this information back in a slightly different manner. Active fingerprinting can determine the operating system and even the patch level.

Which of the following is a characteristic of static routing when compared to dynamic routing?

All routers must be manually updated on the router.

Which of the following is a characteristic of static routing when compared to dynamic routing? All routes must be manually updated on the router. Routers use the hop count to identify the distance to a destination network. Routers can only use static routing when not connected to the Internet. Routers send packets for destination networks to the next hop router.

All routes must be manually updated on the router. Explanation Static routing requires that entries in the routing table are configured manually. Network entries remain in the routing table until manually removed. When changes to the network occur, static entries must be added or removed. The next hop router is used with most routes to identify the next router in the path to the destination, regardless of whether the route is a static or dynamically-learned route. The hop count can be used by static or dynamic routes, depending on the routing protocol used. Static routing can be used for private and public networks, whether connected to the Internet or not.

You manage a server that uses an IP address of 192.168.255.188 with a mask of 255.255.0.0 Which of the following describes the address type?

Classless

You manage a server that uses an IP address of 192.168.255.188 with a mask of 255.255.0.0. Which of the following describes the address type? Classless Classful Multicast Public Broadcast

Classless Explanation Because the IP address is not using the default subnet mask, it is using classless addressing. Classless addressing modifies the length of the subnet mask, using a custom mask value instead of the default subnet mask. Classful addressing uses the default subnet mask. Devices that only support classful addressing assume the subnet mask based on the IP address class. A broadcast address is an address that is sent to all hosts. Broadcast addresses are the last possible address on a subnet. A multicast address is an address that identifies a group of computers. Members of the group share the same multicast address. Multicast addresses are in the range of 224.0.0.0 to 239.255.255.255. A public address is an address that is registered for use on the Internet.

Which of the following terms are often synonymous with or made possible with CIDR? (Select two.) NAT Classless VLSM OSPF Classful

Classless VLSM Explanation Classless InterDomain Routing (CIDR) allows for non-default subnet masks (variable length subnet mask or VLSM). Routers use the following information to identify networks: • The beginning network address in the range • The number of bits used in the subnet mask For example, the subnet 199.70.0.0 with a mask of 255.255.0.0 is represented as 199.70.0.0/16 (with 16 being the number of 1 bits in the subnet mask). Classful addresses rely on the IP address class to identify the subnet mask. Network Address Translation (NAT) allows you to connect a private network to the Internet without obtaining registered addresses for every host. Private addresses are translated to the public address of the NAT router. OSPF is a routing protocol that supports CIDR features.

Client/server Explanation In a client/server network, hosts have specific roles. For example, some hosts are assigned server roles which allows them to provide network resources to other hosts. Other hosts are assigned client roles which allows them to consume network resources. In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources. An intranet is a private network that uses Internet technologies. Services on an intranet are only available to hosts that are connected to the private network. An extranet is a private network that uses Internet technologies, but whose resources are made available to external (but trusted) users. For example, you might create a Web site on a private network that only users from a partner company can access.

Which of the following describes the point where the service provider's responsibility ends and the customer's responsibility begins for installing and maintaining wiring and equipment? Smart jack Punchdown block IDF Demarc Vertical cross connect

Demarc Explanation When you contract with a local exchange carrier (LEC) for data or telephone services, they install a physical cable and a termination jack onto your premises. The demarcation point (demarc) is the line that marks the boundary between the telco equipment and the private network or telephone system. Typically, the LEC is responsible for all equipment on one side of the demarc, and the customer is responsible for all equipment on the other side of the demarc. A smart jack is a special loopback plug installed at the demarcation point for a WAN service. Technicians at the central office can send diagnostic commands to the smart plug to test connectivity between the central office and the demarc. A punchdown block is a block used to connect individual copper wires together. While the demarc might terminate in a punchdown block, punchdown blocks are used within other locations at the customer site. An intermediate distribution frame (IDF) is a smaller wiring distribution point within a building. IDFs are typically located on each floor directly above the main distribution frame (MDF), although additional IDFs can be added on each floor as necessary. A vertical cross connect connects the IDF to the MDF on a different floor.

Demarc extension Explanation A demarc extension extends the demarcation point from its original location to another location within the building. The demarc extension typically consists of a single wire bundle that attaches to the existing demarc and supplies a termination point to a different location. You might need a demarc extension if your network occupies an upper floor of a building. The LEC will typically install the demarc into the MDF on the bottom floor, and you will need to install an extension to place the demarc into the IDF on your floor. A horizontal cross connect connects IDFs on the same floor. Cabling runs horizontally (sideways) between the IDFs. A smart jack is a special loopback plug installed at the demarcation point for a WAN service. Technicians at the central office can send diagnostic commands to the smart plug to test connectivity between the central office and the demarc. Use 66 and 110 blocks to connect individual wires within a wiring closet. These blocks can be used to connect devices to the WAN service wiring, but are not typically used for installing a demarc extension.

A router is connected to network 192.168.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. There is no default route configured on the router. The router receives a packet addressed to network 10.1.0.0/16. What will the router do with the packet? Drop the packet. Send the packet to both networks 192.168.3.0 and 192.168.4.0 to the next hop router. Hold the packet in cache until a matching route is learned or configured. Send the packet out both of its directly connected networks as a broadcast frame.

Drop the packet. Explanation If a packet does not match any route in a routing table, the router will simply drop the packet. In this example, the router does not know about the destination network, and also is not configured with a default route. With a default route, the router will forward the packet to the next hop router specified by the default route.

Which of the following is the best device to deploy to protect your private network from a public untrusted network? Firewall Gateway Hub Router

Firewall Explanation A firewall is the best device to deploy to protect your private network from a public untrusted network. Firewalls are used to control traffic entering and leaving your trusted network environment. Firewalls can manage traffic based on source or destination IP address, port number, service protocol, application or service type, user account, and even traffic content. Routers offer some packet based access control, but not as extensive as that of a full-fledged firewall. Hubs and gateways are not sufficient for managing the interface between a trusted and an untrusted network.

Firewall Explanation The role of a firewall is to provide a barrier between an organization's network and a public network, such as the Internet. Its job is to prevent unauthorized access into the organization's private network. To do this, the firewall examines incoming packets and determines whether they should be allowed to enter based on a set of rules defined by the network administrator.

A router is connected to network 192.168.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24. The router is also configured with a static route of 0.0.0.0 with a mask of 0.0.0.0. The router receives a packet addressed to network 10.1.0.0/16. What will the router do with the packet? Send the packet out both of its directly connected networks to the next hop router. Send the packet out both of its directly connected networks as a broadcast frame. Forward the packet to the next hop router specified by the route to network 0.0.0.0. Drop the packet.

Forward the packet to the next hop router specified by the route to network 0.0.0.0. Explanation A route of 0.0.0.0 with a mask of 0.0.0.0 identifies a default route. The default route is used when no other route is a better match. Packets that match no other networks are sent to the next hop router specified by default route.

What type of virtualization completely simulates a real physical host? Full virtualization Semi-virtualization Paravirtualization Partial virtualization

Full virtualization Explanation In full virtualization, the virtual machine completely simulates a real physical host. This allows most operating systems and applications to run within the virtual machine without being modified in any way. In partial virtualization, only some of the components of the virtual machine are virtualized. Be aware of the following: •The operating system uses some virtual components and some real physical hardware components in the actual device where the hypervisor • The operating system or application must be modified to run in a partial virtualization environment. In paravirtualization, the hardware is not virtualized. Be aware of the following: • All of the guest operating systems running on the hypervisor directly access various hardware resources in the physical device; components are not virtual. • The guest operating systems run in isolated domains on the same physical hardware. • The operating system or application must be modified before they can run in a paravirtualization environment.

You have a private network connected to the Internet. Your routers will not share routing information about your private network with Internet routers. Which of the following best describes the type of routing protocol you would use? Static Link state IGP Dynamic Distance vector BGP

IGP Explanation You would use an Interior Gateway Protocol (IGP) on routers within your network. Routing protocols can be classified based on whether they are routing traffic within or between autonomous systems: An Interior Gateway Protocol (IGP) routes traffic within an AS; an Exterior Gateway Protocol (EGP) routes traffic between ASs. Link state and distance vector describe how routing protocols share routing information. The network size might determine which protocol is best for your network. Static routing uses manually defined routes in the routing table, while dynamic routing uses a protocol so routers learn and share routes with other routers. You can use either static or dynamic routing (or both) on a private network.

Match the default administrative distance with the route type.

Which of the following protocols is used by an e-mail client to retrieve messages from an e-mail server and gives users the option to keep mail messages on the server?

IMAP

You are asked to recommend an email retrieval protocol for a company's sales team. The sales team needs to access email from various locations and possibly different computers. The sales team does not want to worry about transferring email messages or files back and forth between these computers. Which email protocol was designed for this purpose? IMAP SMTP MFTP POP4 POP3

IMAP Explanation The Internet Message Access Protocol (IMAP) is an email retrieval protocol designed to enable users to access their email from various locations without the need to transfer messages or files back and forth between computers. Messages remain on the remote mail server and are not automatically downloaded to a client system. POP3 is an email retrieval protocol that downloads and then deletes messages from a mail server. POP3 is well suited for reading email offline; however, you need to go online when you want to receive and send new messages. Once your new messages have been downloaded to your computer you can log off to read them. This option is often used when email is received over a dialup connection.

Which of the following protocols stores email on the mail server and gives users a choice to download mail or keep it on the server? (Select 2) POP3 SMTP NTP IMAP4

IMAP4 & POP3 Explanation IMAP4 allows a mail server to hold messages for a client. POP3 is a simpler protocol than IMAP4 that downloads email messages and deletes them from the server by default, but most newer POP3 clients provide an option to leave mail on the server after download. SMTP allows a user to send email to a server. The NTP protocol synchronizes the clocks of all computers on a network.

A workstation is connected to a switch on the Gi0/2 interface using a straight through cable. The Ethernet interface in the workstation has been manually configured to use a 100 Mbps link speed and full duplexing. Which of the following are true in this scenario? (Select three.)

If the link speed is 1000 Mbps or faster, full-duplex is used. If the link speed is 10 Mbps or 100 Mbps, half-duplex is used. The switch attempts to sense the link speed. If it can't, the slowest link speed supported on the interface is selected.

Under which of the following circumstances might you implement BGP on your company network and share routes with Internet routers? If the network is connected to the Internet using multiple ISPs. If the network has over 15 areas and uses IPv6. If the network is connected to the Internet using public addressing. If the network has over 15 hops.

If the network is connected to the Internet using multiple ISPs. Explanation Very large networks can use BGP internally, but typically only share routes on the Internet if the AS has two (or more) connections to the Internet through different ISPs. If your network has over 15 hops, use a routing protocol other than RIP. Use OSPF or ISIS to divide your network into areas. Private networks that use public IP addresses do not need to share routes with Internet routers; it is typically the responsibility of the ISP to configure routes into the private network, even when public addressing is being used. A single route out of the private network is all that is required if the network has a single connection to the Internet.

Which of the following attacks, if successful, causes a switch to function like a hub?

MAC flooding MAC flooding overloads the switch's MAC forwarding table to make the switch function like a hub. The attacker floods the switch with packets, each containing different source MAC addresses. The flood of packets fills up the forwarding table and consumes so much of the memory in the switch that it causes the switch to enter a state called failopen mode, in which all incoming packets are broadcast out all ports (as with a hub), instead of just to the correct ports as per normal operation.

Which of the following terms identifies the wiring closet in the basement or a ground floor that typically includes the demarcation point? Smart jack IDF 110 block Horizontal cross connect MDF

MDF Explanation The main distribution frame (MDF) is the main wiring point for a building. The MDF is typically located on the bottom floor or basement. The LEC typically installs the demarc to the MDF. An intermediate distribution frame (IDF) is a smaller wiring distribution point within a building. IDFs are typically located on each floor directly above the MDF, although additional IDFs can be added on each floor as necessary. A horizontal cross connect connects wiring closets on the same floor. A smart jack is a special loopback plug installed at the demarcation point for a WAN service. Technicians at the central office can send diagnostic commands to the smart plug to test connectivity between the central office and the demarc. Use 66 and 110 blocks to connect individual wires within a wiring closet.

Manually reconfigure the default route to point to the new next hop router.

You have a router configured to share routing information using RIP. In addition, you have a single static route that identifies a default route for all other networks. The next hop router for the default route has changed. You need to make the change with the least amount of effort possible. What should you do? Manually reconfigure the default route to point to the new next hop router. Stop and restart the RIP protocol on the router. Force RIP to perform an immediate update. Wait for network convergence to take place.

Manually reconfigure the default route to point to the new next hop router. Explanation With a static route, when changes to the network occur, routing table entries must be modified, added, or removed manually. In this example, the default route was configured manually, so must be manually updated. When using a routing protocol, routing changes are made automatically by routers sharing routing information. To make a change for a dynamic route, simply wait for convergence to occur (the term convergence describes the condition when all routers have the same routing information).

Multicast

Which of the following address types is shared by multiple hosts, and is used to form groups of computers that should receive the same data stream? Simplex Half-duplex Multicast Unicast Broadcast

Multicast Explanation A multicast address is an address that identifies a group of computers. Members of the group share the same multicast address. A unicast address is an address that identifies a single host. A broadcast address is an address that is sent to all hosts. Broadcast traffic is typically only forwarded within (but not between) a subnet. Simplex communication uses a single channel for both sending and receiving. Half-duplex uses a separate channel for sending and receiving, but the channels are shared by multiple devices and can only be used by a single device at a time.

Which type of address is the IP address 232.111.255.250? Multicast Unicast Private Broadcast

Multicast Explanation The address 232.111.255.250 is a multicast address. A multicast address is an address that identifies a group of computers. Members of the group share the same multicast address. Multicast addresses are in the range of 224.0.0.0 to 239.255.255.255. A unicast address is an address that identifies a single host. A broadcast address is an address that is sent to all hosts. Broadcast addresses are the last possible address on a subnet (typically ending in 255). The private IPv4 address ranges are: • 10.0.0.1 to 10.255.255.254 • 172.16.0.1 to 172.31.255.254 • 192.168.0.1 to 192.168.255.254

Which of the following routing protocols divides the network into areas, with all networks required to have an area 0 (area 0 identifying the backbone area)?

OSPF

Which of the following routing protocols uses relative link cost as a metric?

OSPF

Which of the following routing protocols divides the network into areas, with all networks required to have an area 0 (area 0 identifying the backbone area)? RIP EIGRP ISIS OSPF

OSPF Explanation OSPF divides a large network into areas. Each autonomous system requires an area 0 that identifies the network backbone. All areas are connected to area 0, either directly or indirectly through another area. Routes between areas must pass through area 0. ISIS uses areas but does not have an area 0 requirement. Neither RIP nor EIGRP use areas.

Which of the following routing protocols are classified as link state routing protocols? select two

OSPF IS-IS

Which of the following routing protocols are classified as link state routing protocols? (Select two.) EIGRP OSPF RIP ISIS RIPv2

OSPF & IS-IS Explanation Both OSPF and ISIS are link state protocols. Using the link state method, routers share only their directly connected routes using special packets called link-state advertisements (LSAs) and link-state packets (LSPs). These route advertisements are flooded (forwarded) throughout the network. Routers use this information to build a topology database of the network. RIP and RIPv2 are classified as distance vector protocols. Using the distance vector method, routers share their entire routing table with their immediate neighbors. Routes learned from neighboring routers are added to the routing table, then shared with that router's neighbors. EIGRP is a balanced hybrid protocol. A hybrid method combines characteristics of both the distance vector and link state methods. It shares its full routing table at startup, followed by partial updates when changes occur.

Which of the following best describes OSPF? OSPF is a classful link-state routing protocol. OSPF is a classless distance vector routing protocol. OSPF is a classless link-state routing protocol. OSPF is a classful distance vector routing protocol.

OSPF is a classless link-state routing protocol. Explanation OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols. EIGRP is a hybrid protocol that supports classless addressing.

What are the main differences between the OSPF and IS-IS routing protocols?

OSPF requires an area 0, while IS-IS does not.

What are the main differences between the OSPF and ISIS routing protocols? OSPF is a link state protocol, while ISIS is not. OSPF is a classful protocol, while ISIS is a classless protocol. OSPF requires an area 0, while ISIS does not. OSPF is an IGP routing protocol, while ISIS is a BGP routing protocol.

OSPF requires an area 0, while ISIS does not. Explanation Like OSPF, ISIS uses areas when designing the network. However, ISIS does not require an area 0 like OSPF does. Because ISIS was originally designed for non-IP protocols, it can more easily support IPv6 routing. Both OSPF and ISIS have the following characteristics: • Both are link state protocols. • Both are classless protocols, supporting CIDR and VLSM. • Both are Interior Gateway Protocols (IGPs) that are used within an AS.

A Smurf attack requires all but which of the following elements to be implemented?

Padded cell A padded cell is a type of intrusion enticement mechanism similar to a honey pot. A padded cell is a simulated network environment that is created when an intruder is detected. The intruder is transferred into the padded cell where all of its activities are monitored and logged while isolating the intruder from all sensitive information or controls.

A security administrator is conducting a penetration test on a network. She connects a notebook system to a mirror port on a network switch. She then uses a packet sniffer to monitor network traffic to try and determine which operating systems are running on network hosts. Which process did the administrator use in the penetration test in this scenario?

Passive fingerprinting

Passive fingerprinting Passive fingerprinting is a form of system enumeration that is designed to gain as much information about network computers as possible. It passively listens to network traffic generated by network hosts and attempts to identify which operating systems are in use based upon the ICMP message quoting characteristics they use. Portions of original ICMP requests are repeated (or quoted) within each response. Each operating system quotes this information back in a slightly different manner.

Which of the following is the most common form of authentication?

Password Most secure systems require only a username and password to provide users with access to the computing environment. Many forms of online intrusion attacks focus on stealing passwords. This makes using strong passwords very important. Without a strong password policy and properly trained users, the reliability of your security system is greatly diminished.

Which of the following is used to terminate individual wires from a 25 pair or 100 pair cable using female RJ45 ports? 66 block 110 block Patch panel Horizontal cross connect

Patch panel Explanation A patch panel is a device that typically connects individual stranded wires into female RJ45 connectors. For example, you might connect 4 pairs of wires from a punchdown block to a port on the patch panel. On the patch panel, you then connect drop cables (cables with RJ45 connectors) to the patch panel on one end and a computer on the other end. Use 66 and 110 blocks to connect individual wires within a wiring closet. These punchdown blocks connect the individual wires together, but do not terminate in RJ45 connectors. A horizontal cross connect connects IDFs on the same floor.

You have implemented a network where each device provides shared files with all other devices on the network. What type of network do you have? Multiple access Peer-to-peer Polling Client/server

Peer-to-peer Explanation In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources. In a client/server network, hosts have specific roles. For example, some hosts are assigned server roles which allows them to provide network resources to other hosts. Other hosts are assigned client roles which allows them to consume network resources. Polling is a media access method where a single device grants permission to other devices to access the network. Multiple access describes a media access method where each device determines when the medium is free.

You are installing networking cable in the air space between the ceiling and the roof of a building. Which type of cabling should you use?

Plenum

You are adding new wires in your building for some new offices. The building has a false ceiling that holds the lights. You would like to run your Ethernet cables in this area. Which type of cable must you use? Plenum PVC Fiber optic Cat 5e or Cat 6e STP

Plenum Explanation Plenum cable is fire resistant and nontoxic; it must be used when wiring above ceiling tiles. PVC cable cannot be used to wire above ceilings because it is toxic when burned. Cat 5e cables provide better EMI protection than Cat 5 cables, and Cat 6e cables are an improvement over Cat 6 specifications, but neither are a requirement for using in a ceiling area. If the area has a lot of EMI, you might consider using STP or fiber optic cables, but this would not be a requirement just because wires were in a ceiling area. Typically, you can avoid EMI sources by rerouting cables.

Which of the following features is used with digital IP phones to supply power through a switch port? VPN Spanning tree PoE 802.1x Trunking

PoE Explanation Power over Ethernet (PoE) supplies power to end devices through the RJ45 Ethernet switch port. Power to the phone is carried on unused wires within the drop cables. Spanning tree is a protocol on a switch that allows the switch to maintain multiple paths between switches within a subnet. The spanning tree protocol runs on each switch and is used to select a single path between any two switches. Trunking allows a switch to forward VLAN traffic between switches. 802.1x is an authentication protocol used with port security (or port authentication).

You want to connect your client computer to a wireless access point connected to your wired network at work. The network administrator tells you that the access point is configured to use WPA2 Personal with the strongest encryption method possible. SSID broadcast is turned off. Which of the following must you configure manually on the client? (Select three.)

Preshared key AES SSID WPA2 Personal uses a shared key for authentication. Once authenticated, dynamic keys are generated to be used for encryption. WPA2 supports AES and TKIP encryption, with AES being the stronger encryption method. With the SSID broadcast turned off, you will need to manually configure the SSID on the client.

You have a small network at home that is connected to the Internet. On your home network you have a server with the IP address of 192.168.55.199/16. All computers on your home network can connect to the Internet. From your work office, you try to access your home computer using its IP address, but are unable to communicate with the server. You are able to connect to other hosts on the Internet. Why can't you access the server? Private addresses are not accessible through the Internet. The server has been assigned a multicast address. The server must have an entry on a DNS server that exists on the Internet. The server isn't using the default subnet mask.

Private addresses are not accessible through the Internet. Explanation The server has been assigned a private IP address. Private addresses are not accessible from the Internet. Instead, a NAT router translates the private address into a public address, and the public address is used to gain access to the private host.

CorpServ is a small company with 14 client systems and a network printer. Because there are only a limited number of networked systems, you decide to use APIPA addressing for the network. With APIPA configured, all systems are able to communicate with each other but you are having trouble configuring Internet access. What is the likely cause of the problem?

Private addresses cannot directly communicate to hosts outside the local subnet.

Which protocol does HTTPS use to offer greater security in Web transactions?

SSL HTTPS uses Secure Sockets Layer (SSL) to offer greater security in Web transactions.

SSL Ports must be opened in firewalls to allow VPN protocols. For this reason, using SSL for the VPN often works through firewalls when other solutions do not because SSL uses port 443--a port that is often already open to allow HTTPS traffic. In addition, some NAT solutions do not work well with VPN connections.

You can use a variety of methods to manage the configuration of a network router. Match the management option on the right with its corresponding description on the left. (Each option can be used more than once.)

Which of the following forms of optical fiber would usually be used to connect two buildings across campus from each other, which are several kilometers apart? Fibre Channel mode Multimode Single mode Dual mode

Single mode Explanation In this scenario, use single mode fiber optic cables. Fiber optic is graded as single mode or multimode. Single mode consists of a single very thin core which produces fewer reflections. This provides greater effective bandwidth over greater distances. Multimode is less costly than single mode fiber. Multimode transmits multiple light rays concurrently. Multimode is used to transmit over shorter distances as the rays tend to disperse as the transmission distance increases. Fibre channel is a network topology used in storage area networks.

You would like to implement 10 Gbps Ethernet over a distance of at least 10 kilometers. Which of the following would meet the requirement for this implementation? (Select three.) 10GBaseER standards 10GBaseLR standards Multimode fiber Single mode fiber 10GBaseSR standards

Stateless auto configuration

You are the network administrator for a small company that implements NAT to access the Internet. However, you recently acquired 5 servers that must be accessible from outside your network. Your ISP has provided you with 5 additional registered IP addresses to support these new servers but you don't want the public to access these servers directly. You want to place these servers behind your firewall on the inside network yet still allow them to be accessible to the public from the outside. Which method of NAT translation should you implement for these 5 servers?

Static

Match the IPv6 address configuration method on the right with it's definition on the left.

Static Full Assignment: The entire 128-bit address and all other configuration information is statically assigned to the host. Static partial Assignment: The prefix is statically assignment and the interface ID is delivered from the MAC address. Stateless Auto-configuration: Clients automatically generate the interface ID and learn the subnet prefix and default gateway through the neighbor discovery protocol (NDP) Stateful DHCPv6: Provides each client an IP address, default gateway, and other IP configuration Stateless DHCPv6: Supplies the client with the DNS server IP address only. Does not provide the client with an IP address and does not track the status of each client.

You have a small network at home that is connected to the Internet. On your home network you have a server with the IP address of 192.138.55.199/16.

You want to configure the server as a Web server and allow Internet hosts to contact the server to browse a personal website. What should you use to allow access?

Static NAT

You have a small network at home that is connected to the Internet. On your home network you have a server with the IP address of 192.168.55.199/16. You have a single public address that is shared by all hosts on your private network. You want to configure the server as a Web server and allow Internet hosts to contact the server to browse a personal Web site. What should you use to allow access? DNS A record Static NAT DNS CNAME record Multicast Dynamic NAT

Static NAT Explanation Static NAT maps an internal IP address to a static port assignment. Static NAT is typically used to take a server on the private network (such as a Web server) and make it available on the Internet. External hosts contact the internal server using the public IP address and the static port. Using a static mapping allows external hosts to contact internal hosts. Dynamic NAT automatically maps internal IP addresses with a dynamic port assignment. On the NAT device, the internal device is identified by the public IP address and the dynamic port number. Dynamic NAT allows internal (private) hosts to contact external (public) hosts but not vice versa. External hosts cannot initiate communications with internal hosts. DNS records associate a host name with an IP address. With multicast, a single data stream can be forwarded to all computers that are members of the same multicast group.

Demarc extension Horizontal cross connect Vertical cross connect Smart jack

Vertical cross connect Explanation A vertical cross connect connects the main distribution frame (MDF) on the main floor to intermediate distribution frames (IDFs) on upper floors. Cabling runs vertically (up and down) between the MDF and the IDFs. A horizontal cross connect connects IDFs on the same floor. Cabling runs horizontally (sideways) between the IDFs. A smart jack is a special loopback plug installed at the demarcation point for a WAN service. Technicians at the central office can send diagnostic commands to the smart plug to test connectivity between the central office and the demarc. A demarc extension extends the demarcation point from its original location to another location within the building. The demarc extension typically consists of a single wire bundle that attaches to the existing demarc and supplies a termination point to a different location. You might need a demarc extension if your network occupies an upper floor of a building. The LEC will typically install the demarc into the MDF on the bottom floor, and you will need to install an extension to place the demarc into the IDF on your floor.

How do switches and bridges learn where devices are located on a network? When a frame enters a port, the destination IP address is copied from the frame header. When a frame enters a port, the source IP address is copied from the frame header. When a frame enters a port, the source MAC address is copied from the frame header. When a frame enters a port, the destination MAC address is copied from frame header.

When a frame enters a port, the source MAC address is copied from the frame header. Explanation Bridges and switches learn addresses by copying the MAC address of the source device and placing it into the MAC address table. The port number which the frame entered is also recorded in the table and associated with the source MAC address. The switch or the bridge cannot record the destination MAC address because it does not know the port that is used to reach the destination device. Bridges and switches operate at Layer 2 and do not use IP addresses (which exist at Layer 3).
