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

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

What information does the next hop entry in a routing table identify? - The first router in the path to the destination network. - The last router in the path to the destination network. - The number of routers that the packet must go through to reach 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.
What is the primary purpose of gateway redundancy? - To overcome a single point of failure on the next hop router. - To provide a default gateway so hosts may communicate outside their local subnet. - To prevent the overloading of the default gateway's CPU. - To overcome the limitations of IPv4 and provide a redundant IP addressing scheme for the local subnet.
To overcome a single point of failure on the next hop router.
What device sends signals from a computer onto a network? - Transceiver - Router - Cable - Gateway
Transceiver A transceiver (short for transmitter/receiver) sends signals to and receives signals from the network. It translates the parallel data stream of the computer to the serial data stream of the network and vice versa. Most transceivers are now built into network interface cards (NICs).

You administer a network with Windows 2000 and UNIX servers, and Windows 2000 Professional, Windows 98, and Macintosh clients. A user of a Windows 98 computer calls you one day and says he is unable to access resources on the network. You type ipconfig on the user's computer and receive the following output: 0 Ethernet adapter: IP address. . . . . . . . . : 169.254.1.17 Subnet Mask . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . : You also check your NIC and see the link light on. What might the problem be? - Unavailable DHCP server - The user changed the configuration of the computer - Bad NIC - Missing default gateway - Misconfigured DNS server
Unavailable DHCP server
Which type of address is the IP address 198.162.12.254/24? - Unicast - Broadcast - Multicast - Private
Unicast
You manage a network that uses a single switch. All ports within your building connect through the single switch. In the lobby of your building are three RJ-45 ports connected to the switch. You want to allow visitors to plug into these ports to gain Internet access, but they should not have access to any other devices on your private network. Employees connected throughout the rest of your building should have both private and Internet access. Which feature should you implement? - Port authentication - VLANs - Spanning tree - PoE
VLANs
When would you typically use an RJ-11 connector? - When using Cat 3 cables. - When using Cat 5 or higher cables. - When using RG-6 cables. - When connecting a phone to a phone line. - When using single mode fiber optic cables. - When using multimode fiber optic cables.
When connecting a phone to a phone line.
You are implementing a DHCP server for your segment. Your segment's IP address is 192.168.1.0. Your default gateway address is 192.168.1.254. Your DNS server address is 192.168.1.1. Your default gateway is configured as a NAT router to translate addresses between network segments. You configured the 03 Router option on your DHCP server so it can deliver the IP address of the default gateway to workstations. After configuring your workstations to get their IP addressing information dynamically, your users complain that they are unable to access websites on the Internet. How can you resolve this problem? - You can't implement a DHCP server in conjunction with a NAT router. - You must configure Automatic Private IP Addressing (APIPA) on each workstation using default settings. - You must configure your DHCP server with an option that enables IP forwarding (Option19). - You must configure your DHCP server with an option that delivers the IP address of the DNS server (Option 06). - You must implement a BOOTP server instead of a DHCP server. - You must configure your DHCP server with an option that delivers the IP address of the default World Wide Web server (Option 72).
You must configure your DHCP server with an option that delivers the IP address of the DNS server (Option 06).
In which of the following situations might you use an RJ-11 connector? - You want to connect the 10BaseT network card in your computer to a switch. - You want to connect your computer to the Internet with a dial-up connection. - You want to upgrade your 10BaseT network to 100BaseT. - You want to test a network cable to see if there is a break in the line.
You want to connect your computer to the Internet with a dialup connection.
