You and your team are evaluating the use of OSPFv3 in your IPv6 network. Which of the following statements is true of OSPFv3? A.There will be a higher demand on the processor to run the link-state routing algorithm B.Router IDs must match for adjacency formation C.Area IDs do not need to match for adjacency formation D.Area types do not need to match for adjacency formation

Answer: A There will be a higher demand on the processor to run the link-state routing algorithm. As with OSPFv2, OSPFv3 uses the Shortest Path first (SPF) algorithm, which is processor intensive. It is one of the only downsides of using the algorithm.

You network team is exploring the use of switch staking. Which of the following statements is NOT true of switch stacking? A.The master switch is the only switch with full access to the interconnect bandwidth B.Switches are connected with special cable C.The stack has a single IP address D.Up to nine switches can be added to the stack

Answer: A All switches in the stack have full access to the interconnect bandwidth, not just the master switch. The master switch is elected from one of the stack members. It automatically configures the stack with the currently running IOS image and a single configuration file. The switches are indeed connected with special cables that form a bidirectional closed loop path.

Which of the following is NOT a possible component of Enhanced Interior Gateway Routing Protocol's (EIGRP) composite metric? A.Cost B.Load C.Delay D.Bandwidth

Answer: A Explanation: Cost is not a component of EIGRP's composite metric. The cost, or efficiency, of a path is used as a metric by the Open Shortest Path First (OSPF) routing protocol. Enhanced IGRP (EIGRP) is Cisco Systems' proprietary routing protocol. It can use bandwidth, delay, load, reliability, and maximum transmission unit (MTU) to calculate the metric. Of these five metrics, by default, only minimum bandwidth and delay are used to compute the best path. The metric for EIGRP can be calculated with this formula: Metric = [K1 * Bandwidth + (K2 * Bandwidth) / (256-load) + K3*Delay] * [K5 / (reliability + K4)] The default constant values for Cisco routers are K1 = 1, K3 = 1, and K2 = 0, K4 = 0, K5 = 0. In the default setting, K1 and K3 have non-zero values, and therefore, by default, the metric is dependent on bandwidth and delay.

Enhanced Interior Gateway Routing Protocol (EIGRP) uses which algorithm to select the best path to the destination? A.Diffusing Update Algorithm (DUAL) B.Dijkstra algorithm C.Bellman-Ford algorithm D.Shortest Path First (SPF) algorithm

Answer: A Explanation: EIGRP uses the Diffusing Update Algorithm (DUAL) to select the best path to the destination. EIGRP is a classless protocol that allows the use of variable length subnet masks (VLSM), and supports classless interdomain routing (CIDR) for the allocation of IP addresses.

You are the network administrator for your company. Your company has opened a new site in London. The Chief Technical Officer (CTO) of the company wants to implement a routing protocol that can provide the following features: - Supports multiple large networks - Does not require a hierarchical physical topology - Supports VLSM - Provides loop prevention and fast convergence - Provides load balancing over un-equal cost links Which routing protocol should be implemented in the new site? A.Enhanced Interior Gateway Routing Protocol (EIGRP) B.Open Shortest Path First (OSPF) C.Interior Gateway Routing Protocol (IGRP) D.Routing Information Protocol version 2 (RIPv2)

Answer: A Explanation: Enhanced Interior Gateway Routing Protocol (EIGRP) is the routing protocol that should be implemented for this scenario. EIGRP is a classless protocol that allows the use of variable length subnet masks (VLSM) and classless interdomain routing (CIDR) for the allocation of IP addresses.

You are configuring a serial link between a Cisco router and a router produced by another vendor. What would be the advantages of using Point to Point Protocol (PPP) over High Level Data Link Control (HDLC) in this scenario? A.HDLC has a proprietary "type" field that may be incompatible with equipment from other vendors. B.HDLC is not available on non-Cisco routers. C.PPP is faster. D.PPP performs error checking

Answer: A Explanation: High Level Data Link Control (HDLC) has a proprietary "type" field that may be incompatible with equipment from other vendors. It is recommended that PPP always be used when combining equipment from multiple vendors because this Data Link layer WAN protocol is an industry standard. PPP is implemented in the same manner on all PPP-capable equipment.

Which protocol is responsible for negotiating and maintaining Point-to-Point Protocol (PPP) connections? A.LCP B.NCP C.BRI D.ISDN

Answer: A Explanation: Link Control protocol (LCP) has the primary responsibility of negotiating and maintaining a PPP connection. LCP, defined in Request for Comments (RFCs) 1548 and 1570, has the primary responsibility to establish, configure, authenticate, and test a PPP connection

What is the significance of the following BECN packet statistics? Router# show frame-relay pvc 16 PVC Statistics for interface serial0 (Frame Relay DTE) DLCI = 16, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0 input pkts 0 output pkts 0 in bytes 0 out bytes 0 dropped pkts 0 in FECN pkts 0 in BECN pkts 100 out FECN pkts 0 out BECN pkts 0 Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 71 <<output omitted>> A.The router is experiencing congestion in sending frames. B.The router is experiencing congestion in receiving frames. C.The Frame Relay mapping table is missing an entry. D.The Frame Relay mapping table is corrupt.

Answer: A Explanation: When frames arrived at a router with the Backwards Explicit Congestion Notification (BECN) bit set, congestion was encountered in the opposite direction from which the frame was traveling. This bit is set by the Frame Relay switch. If an incoming packet has the BECN bit set, then this indicates congestion in outgoing packets, so the router will experience congestion in sending frames.

You are implementing IP SLA and would like to use it to measure hop-by-hop response time between a Cisco router and any IP device on the network. Which of the following IP SLA operations would you use for this? A.ICMP path echo operation B.Internet Control Message Protocol Echo Operation C.UDP Jitter Operation for VoIP D.UDP Jitter Operation

Answer: A The ICMP path echo operation discovers the path using the traceroute command, and then measures response time between the source router and each intermittent hop in the path. IP SLAs allow users to monitor network performance between Cisco routers or from a Cisco router to a remote IP device. The Internet Control Message Protocol (ICMP) Echo Operation measures end-to-end response time between a Cisco router and any IP-enabled device. Response time is computed by measuring the time taken between sending an ICMP echo request message to the destination and receiving an ICMP echo reply. It does not measure hop-by-hop response time.

Consider the following diagram: F0/0 192.168.1.16/28<--Router A<--172.16.0.4/30-->Router B-->F0/0 192.168.1.32/28 Which of the following routing protocols could NOT be used with this design? A.RIPv1 B.RIPv2 C.EIGRP D.OSPF

Answer: A The network design displayed has subnets of a major classful network located in opposite directions from the perspective of some of the individual routers. This configuration can be accommodated by any routing protocol that supports Variable Length Subnet masks (VLSM) or the transfer of subnet mask information in routing advertisements. RIPv1 supports neither of these. RIPv1 will automatically summarize routing advertisements to their classful network (in this case 192.168.1.0/24). This action will cause some of the routers to have routes to the same network with different next hop addresses, which will NOT work.

What two devices can be connected to a router WAN serial interface that can provide clocking? (Choose two.) Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 15 A.CSU/DSU B.switch C.modem D.hub

Answer: A, C

On which of the following networks will OSPF elect a designated router (DR)? (Choose two.) A. Broadcast B. NBMA (Non-Broadcast Multi-Access) C. Point-to-point D. Point-to-multipoint

Answer: A,B

Router 5 has four interfaces. The networks hosted on each interface are as follows: Fa0/1 192.168.5.4/29 Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 75 Fa0/2 192.168.6.0/24 Fa0/3 192.168.7.0/24 S0/0 172.16.5.0/24 You execute the following commands on the router: Router5(config)# router bgp 20 Router5(config-router)# network 192.168.5.0 Router5(config-router)# network 192.168.6.0 Router5(config-router)# network 192.168.7.0 Router5(config-router)# network 172.16.5.0 Router5(config-router)# neighbor 172.16.5.2 remote-as 50 Router5(config-router)# aggregate-address 192.168.5.0 255.255.252.0 After this command sequence is executed, what routes will be present in the routing table of the router at 172.16.5.2? (Choose all that apply.) A.192.168.5.4/29 B.172.16.5.0/24 C.192.168.6.0/24 D.192.168.7.0/24 E.none of these will be present F.only network addresses beginning with 192 will be present

Answer: A,B,C,D Explanation: Despite the inclusion of the command aggregate-address 192.168.5.0 255.255.252.0, all subnets of the aggregate route will also be placed in the routing updates because of the omission of the summary-only keyword. Therefore, 192.168.5.4/29, 172.16.5.0/16, 192.168.6.0/24 and 192.168.7.0/24 will be present.

Which of the following protocols allow the root switch location to be optimized per VLAN? (Choose all that apply.) A.PVST+ B.RSTP C.PVRST D.STP

Answer: A,C Explanation: Both Per VLAN Spanning Tree Plus (PVST+) and Per VLAN Rapid Spanning Tree (PVRST) protocols allow for a spanning tree instance for each VLAN, allowing for the location optimization of the root bridge for each VLAN. These are Cisco proprietary enhancements to the 802.1d and 802.1w standards, respectively.

What will be the effects of executing the following set of commands? (Choose all that apply.) #router eigro 44 # network 10.0.0.0 #network 192.168.5.0 A.EIGRP will be enabled in AS 44 B.EIGRP instance number 44 will be enabled C.EIGRP will be activated on the router interface 10.0.0.2/8 D.EIGRP will be activated on the router interface 192.168.5.9/24 E.EIGRP will be activated on the router interface 10.0.5.8/16 F.EIGRP will be activated on the router interface 192.168.6.1/24

Answer: A,C,D,E

Examine the network diagram. Which switch port(s) will be in a forwarding state? (Choose two.) SW1 - MAC: 08BA.B461.F23C SW2 - MAC: 0B31.624E.96DD The SWs are connected with 2 cables, their F0/1 and F0/2.

Answer: A,D Explanation: Both switch ports on Switch A and Fa0/1 on Switch B will be in a forwarding state. Switch A will become the STP root bridge due to its lower MAC address. All ports on the root bridge will become designated ports in a forwarding state. Switch B has redundant connectivity to the root bridge, and must block one of its interfaces to prevent a switching loop. Both interfaces are the same speed (FastEthernet), and thus their cost to the root is the same. Finally, the interface with the lowest number will become the forwarding port. F0/1 has a lower port number than F0/2, so F0/1 becomes a forwarding port, and F0/2 becomes a blocking port.

Which commands would be used to enable Enhanced Interior Gateway Routing Protocol (EIGRP) on a router, and configure the IP addresses 10.2.2.2 and 192.168.1.1 as a part of complete EIGRP configuration? (Choose three.) A.router eigrp 10 B.router eigrp C.network 10.2.2.2 D.network 10.0.0.0 E.network 192.168.1.0 F.network 192.168.1.1

Answer: A,D,E Explanation: The router eigrp 10 command is used to enable EIGRP on a router. The network 10.0.0.0 and network 192.168.1.0 commands are used to activate EIGRP over the interfaces configured with IP addresses 10.2.2.2 and 192.168.1.1. If we were given the subnet mask for the two interfaces, we could include that in the network command as well.

Which of the following techniques is NOT used by distance vector protocols to stop routing loops in a network? A. Split horizon B. Spanning Tree Protocol (STP) C. Holddowns D. Route poisoning

Answer: B

You are troubleshooting a problem with two routers configured in a HSRP group. You intended to configure the routers so that Router A and Router B would each track their respective Fa0/1 interfaces and decrement their priorities for several VLAN groups if the tracked interface went down. However, you find that Router A is not taking over as the active device for the HSRP group on VLAN 101 when the Fa0/1 interface on Router B fails. Which command would NOT be useful for discovering the problem? A.show running-configuration B.show vlans C.show standby brief D.show standby

Answer: B

Which of the following technologies should be used to prevent a switching loop if a switch is connected to a port configured for PortFast? A.RSTP B.BPDU Guard C.Root Guard D.PVST

Answer: B BPDU Guard prevents switching loops in the case of a switch being connected to a PortFast interface. PortFast is used for ports that connect to host systems, such as workstations and printers, and allows the port to immediately enter a forwarding state. This bypasses the normal 30- second delay that Spanning Tree Protocol would normally use to determine if a switch has been connected to the port. Implementing BPDU Guard will disable the port if a switch is connected and a BPDU is received.

Which of the following is NOT a dynamic table maintained by a router running the EIGRP routing protocol? A.topology table B.CAM table C.routing table D.neighbor table

Answer: B Explanation: All are tables maintained by a router running the EIGRP routing protocol except a Content Addressable Memory (CAM) table. This table is only present on a switch. It is used to maintain the two MAC addresses involved in a conversation between computers so that the conversation can be routed once and then switched thereafter which is a much faster process. EIGRP maintains three dynamic tables in RAM: - Neighbor table, which is a list of all neighboring EIGRP routers on shared subnets - Topology table, which contains all discovered network paths in the internetwork - Routing table, which contains the best path (based on lowest metric) to each destination

Which type of connector is used for an Integrated Services Digital Network Basic Rate Interface (ISDN BRI) connection? A.DB-60 B.RJ-45 Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 67 C.AUI D.Console

Answer: B Explanation: An RJ-45 connector is used for an ISDN BRI connection. A BRI port is used in order to connect an asynchronous BRI interface.

You recently implemented SNMPv3 to increase the security of your network management system. A partial output of the show run command displays the following output that relates to SNMP: <output omitted> snmp-server group TECHS v3 noauth read TECHS write TECHS Which of the following statements is true of this configuration? A.It provides encryption, but it does not provide authentication B.It provides neither authentication nor encryption C.It provides authentication, but it does not provide encryption D.It provides both authentication and encryption

Answer: B Explanation: It provides neither authentication nor encryption. In SMNPv3, there are three combinations of security that can be used: - noAuthNoPriv- no authentication and no encryption; includes the noauth keyword in the configuration - AuthNoPriv - messages are authenticated but not encrypted; includes the auth keyword in the configuration - AuthPriv - messages are authenticated and encrypted; includes the priv keyword in the configuration In this case, the keyword noauth in the configuration indicates that no authentication and noencryption are provided. This makes the implementation no more secure than SNMPv1 or SNMPv2.

Consider the following output of the show ip interface brief command: You have a single area OSPF network. What command should you execute on R1 so that OSPF is operational on the E0, S1, and S2 interfaces ONLY? ***From the list of interfaces these three have the following IPs: E0: 192.168.12.65 S1: 192.168.12.125 S2:192.168.12.121 **** A.R1(config-router)#network 192.168.12.64 0.0.0.127 area 0 B.R1(config-router)#network 192.168.12.64 0.0.0.63 area 0 C.R1(config-router)#network 192.168.12.64 0.0.0.66 area 0 D.R1(config-router)#network 192.168.12.64 255.255.255.192 area 0 E.R1(config-router)#network 192.168.12.64 0.0.0.63 area1

Answer: B Explanation: The command R1(config-router)#network 192.168.12.64 0.0.0.63 area 0 would ensure that OSPF is operational on the E0, S1, and S2 interfaces only. When executing the network command in OSPF, a wildcard mask in combination with the network ID used in the command determines which interfaces will participate in OSPF. Any interfaces that are included in the network created by the network ID and the mask will participate in OSPF.

What command produced the following as a part of its output? 1 14.0.0.2 4 msec 4 msec 4 msec 2 63.0.0.3 20 msec 16 msec 16 msec 3 33.0.0.4 16 msec * 16 msec A.Ping B.Traceroute C.Tracert D.Extended ping

Answer: B Explanation: The output displayed is a part of the output from executing the traceroute command. The traceroute command finds the path a packet takes while being transmitted to a remote destination.

Examine the partial output from two adjacent routers: RTR78# show ip ospf Routing Process 201 with ID 192.0.2.1 VRF default Stateful High Availability enabled Graceful-restart is configured Grace period: 60 state: Inactive Last graceful restart exit status: None Supports only single TOS(TOS0) routes Supports opaque LSA This router is an autonomous system boundary Administrative distance 110 Reference Bandwidth is 40000 Mbps Initial SPF schedule delay 3000.000 msecs, minimum inter SPF delay of 2000.000 msecs, maximum inter SPF delay of 4000.000 msecs Initial LSA generation delay 3000.000 msecs, RTR79# show ip ospf Routing Process 202 with ID 192.0.2.1 VRF default Stateful High Availability enabled Graceful-restart is configured Grace period: 60 state: Inactive Last graceful restart exit status: None Supports only single TOS(TOS0) routes Supports opaque LSA This router is an autonomous system boundary Administrative distance 110 Reference Bandwidth is 30000 Mbps Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 79 Initial SPF schedule delay 3000.000 msecs, minimum inter SPF delay of 2000.000 msecs, maximum inter SPF delay of 4000.000 msecs Initial LSA generation delay 3000.000 msecs, Which of the following statements describes why the two routers are NOT forming an OSPF neighbor adjacency? A.The process IDs do not match B.The router IDs are misconfigured C.The distance is misconfigured D.The reference bandwidth does not match

Answer: B Explanation: The output shows that the router IDs for RTR78 and RTR79 are the same value, which should not be the case. One of the two routers has been misconfigured with the other router's ID. This will prevent an OSPF neighbor adjacency from forming.

Which command was used to generate the following output? P 172.16.16.0/24, 1 successors, FD is 284244 via 172.16.250.2 (284244/17669856), Serial0/0 via 172.16.251.2 (12738176/27819002), Serial0/1 P 172.16.250.0/24, 1 successors, FD is 2248564 via Connected, Serial0/0 P 172.16.10.0/24 1 successors, FD is 284244 via 172.16.50.1 (284244/17669856), Serial1/0 A.show ip route eigrp B.show ip eigrp topology C.show eigrp topology D.show eigrp ip topology E.debug ip eigrp

Answer: B Explanation: The show ip eigrp topology command is used to display the EIGRP topology table, which contains a record of all paths to all destination networks in the EIGRP autonomous system. Active routes (successors) and backup routes (feasible successors) are both stored in the topology table, whereas only successor routes are stored in the routing table. This is why there are two routes listed to the 172.16.16.0 network, even though their costs are not equal.

You instructed your assistant to add a new router to the network. The routers in your network run OSPF. The existing router, OldRouter, is configured as follows: router ospf 1 network 192.168.5.0 0.0.0.255 area 0 network 192.168.10.0 0.0.0.255 area 0 The OldRouter interface that connects to NewRouter is 192.168.5.3/24. Your assistant shows you the configuration that will be implemented: newrouter(config)# router ospf 1 newrouter(config-router)# network 192.168.5.0 255.255.255.0 area 0 What is wrong with this configuration? A.The area ID is incorrectly configured. B.The wildcard mask is incorrectly configured. C.The network statement is incorrectly configured. D.The process ID number is incorrectly configured.

Answer: B Explanation: When entering network statements for OSPF, a wildcard mask is used instead of a regular mask. Since the network connecting the two routers is a class C network, as shown by the address 192.168.5.0/24, the wildcard mask should be 0.0.0.255 rather than 255.255.255.0. With wildcard masks, the 0s octets must match, and the 255s octets do not have to match.

How is load balancing achieved when implementing HSRP? A.By configuring multiple gateways on the routers B.By using multiple HSRP groups C.By configuring the same priority on all HSRP group members D.By configuring multiple virtual router addresses

Answer: B Explanation: When implementing Hot Standby Router Protocol (HSRP), load balancing is achieved by using multiple HSRP groups. Routers configured for HSRP can belong to multiple groups and multiple VLANs. By configuring one group to be active for Router A and standby for Router B, and the second group to be active for Router B and standby for Router A, both routers A and B can be used to pass traffic, as opposed to one sitting idle. Load balancing cannot be achieved by configuring multiple gateways on the routers. The routers have one IP address. Each group will have a virtual IP address.

You have two routers in your OSPF area 0. Router 1 is connected to Router 2 via its Serial 1 interface, and to your ISP via the Serial 0 interface. Router 1 is an ASBR. After your assistant configures a default route on Router 1, you discover that whenever either router receives packets destined for networks that are not in the routing tables, it causes traffic loops between the two routers. To troubleshoot, you execute the show run command on Router 1. Part of the output is shown below: <output omitted> IP route 0.0.0.0 0.0.0.0 serial 1 Router ospf 1 Network 192.168.5.0 0.0.0.255 area 0 Default-information originate Which command or set of commands should you execute on Router 1 to stop the looping traffic while maintaining Router 2's ability to send traffic to the Internet? A.Execute the no default-information originate command. B.Execute the no ip route 0.0.0.0 0.0.0.0 serial 1 command and then execute the ip route 0.0.0.0 0.0.0.0 serial 0 command. C.Execute the default-information originate always command. D.Execute the no network 192.168.5.0 area 0 command and then execute the network 192.168.5.0 255.255.255.0 area 0 command.

Answer: B Explanation: You should execute the no ip route 0.0.0.0 0.0.0.0 serial 1 command followed by the ip route 0.0.0.0 0.0.0.0 serial 0 command. The original configuration command was executed on the wrong interface on Router 1 by your assistant. It should be executed on Serial 0, which is the connection to the ISP. The show run command indicates that with the current configuration, if Router 2 receives a packet not in its table, it sends it to Router 1, and then Router 1 sends it back out on Serial 1. This redirects the packet back to Router 2, and the loop begins. By changing the configuration to Serial 0, Router 1 will start forwarding all traffic not in the routing table to the ISP.

You are advising a client on the options available to connect a small office to an ISP. Which of the following is an advantage of using an ADSL line? A.it uses the existing cable TV connection B.it uses the existing phone line C.you receive a committed information rate (CIR) from the provider D.the upload rate is as good as the download rate

Answer: B Explanation: xDSL lines, including the ADSL variant, use the existing phone line and as such make installing only a matter of hooking up the DSL modem to the line.

A.The physical IP address of R2 is 2.2.2.2 B.The connection will operate in IP mode C.The configuration will increase packet fragmentation D.The configuration alters the maximum segment size

Answer: C

You just finished configuring VLAN Trunking Protocol (VTP) in a network containing five switches. One of the switches is not receiving VLAN information from the switch that is acting as the server. Which of the following could NOT be a reason why the switch is not receiving the information? A. The VTP domain name on the switch may be misspelled B. The VTP password may be misspelled on the switch C. The configuration revision number may be out of sync D. The VTP version used on the switch may be different

Answer: C

You execute the ping command from a host, but the router does not have a path to its destination. Which of the following ICMP message types will a client receive from the router? A.ICMP redirect B.ICMP time exceeded C.ICMP destination unreachable D.ICMP echo-reply Answer: C

Answer: C An ICMP redirect message response is received when the router is configured to direct clients to a different router for better routing. An ICMP time-exceeded message response occurs when the router successfully sent the packet but did not receive an answer within the allotted time; in other words, the time-to-live of the ICMP packet has been exceeded. An ICMP echo-reply would be the response received if the destination received the ping command and responded successfully.

You want to encrypt and transmit data between peer routers with high confidentiality. Which protocol option should you choose? A.Authentication Header (AH) in tunnel mode B.Authentication Header (AH) in transport mode C.Encapsulating Security Payload (ESP) in tunnel mode D.Encapsulating Security Payload (ESP) in transport mode

Answer: C ESP is defined in RFC 2406. ESP can provide data integrity and authentication, but its primary purpose is to encrypt data crossing the tunnel. There are two reasons why ESP is the preferred building block of IPSec tunnels:

Which statement is supported by the following output? A.EIGRP supports load-balancing over three equal-cost paths B.EIGRP supports load-balancing over three unequal-cost paths C.EIGRP supports load-balancing over four equal-cost paths D.EIGRP supports load-balancing over four unequal-cost paths In the question we have the output of the command The output show

Answer: C Explanation: The Maximum path: 4 output indicates that Enhanced Interior Gateway Routing Protocol (EIGRP) will support round-robin load-balancing over four equal-cost paths. This is a default setting, and is a true statement for most routing protocols (including RIP, OSPF and IS-IS). Equal-cost paths are different routes to the same destination network with identical metrics, as determined by the routing protocol. Most routing protocols allow this maximum to be raised up to 16 with the maximum-paths command.

You know that Router2 is configured for RIP. Which Cisco Internetwork Operating System (IOS) command is used to view the current state of all active routing protocols? A.show ip arp B.debug ip rip C.show ip protocols D.show ip routing process E.show arp F.show interfaces

Answer: C Explanation: The show ip protocols command is used to view the current state of active routing protocols. This command is issued from Privileged EXEC mode.

Which of the following statements best describes the result of issuing the command standby 44 timers 3 1 on an HSRP router? A.The holdtime will be set to a value of 3, and the hellotime will be set to a value of 1. B.The status of the standby router will be displayed as unknown expired. C.The role of active router will be passed repeatedly from one router to another. D.The router will be configured to reassume the role of active router in the event that the router fails and is subsequently restarted.

Answer: C Explanation: When the command standby 44 timers 3 1 is issued on a Hot Standby Routing Protocol (HSRP) router, the role of active router will be passed repeatedly from one router to another. This behavioroccurs when the timers are set incorrectly. The syntax for the standby timers command is standby [group-number] timers [hellotime holdtime]. The hellotime variable is the number of seconds between hello messages and is set to a value of 3 by default

Which Cisco Internetwork Operating System (IOS) command is used to view information about Open Shortest Path First (OSPF) routing processes? A.show ip ospf database B.show ip ospf statistics C.show ip ospf D.show ip ospf traffic

Answer: C The show ip ospf command is used to view information about the OSPF routing processes. It doesso by displaying the collection of link states present in the database.

You receive the following error message after addressing and enabling an interface: %192.168.16.0 overlaps with FastEthernet0/0 Which two are NOT the causes of the error message? (Choose two.) A.incorrect subnet mask in the new interface B.incorrect IP address on the new interface C.incorrect encapsulation configured D.failure to issue the no shutdown command

Answer: C, D

You manage the EIGRP subnet in your organization. You have enabled EIGRP for IPv6 on all the routers in the EIGRP AS 260 using the following commands on all the routers: The ipv6 unicast-routing command in global configuration mode The interface command in global configuration mode The ipv6 enable command in interface configuration mode The ipv6 eigrp command in interface configuration mode The ipv6 router eigrp command in global configuration mode The eigrp router-id command in global configuration mode During verification, you discover that EIGRP for IPv6 is not running on the routers. Which of the following should be done to fix the issue? A.The ipv6 address command should be executed in interface configuration mode. B.The ipv6 address command should be executed in router configuration mode. C.The eigrp router-id command should be executed in interface configuration mode. D.The eigrp router-id command should be executed in router configuration mode

Answer: D

When executed on a HSRP group member named Router 10, what effect does the following command have? Router10(config-if)# standby group 1 track serial0 25 A.It will cause the router to increase its HSRP priority by 25 if the Serial0 interface on the standby router goes down B.It will cause the router to shut down the Serial0 interface if 25 packets have been dropped C.It will cause the router to notify Router 25 is serial 0 goes down D.It will cause the router to decrement its HSRP priority by 25 if Serial 0 goes down

Answer: D Interface tracking can be configured in Hot Standby Routing Protocol (HSRP) groups to switch traffic to the standby router if an interface goes down on the active router. This is accomplished by having the active router track its interface. If that interface goes down, the router will decrement its HSRP priority by the value configured in the command. When properly configured, this will cause the standby router to have a higher HSRP priority, allowing it to become the active router and to begin serving traffic.

Which of the following is NOT a feature offered by Enhanced Interior Gateway Routing Protocol (EIGRP)? A.variable length subnet masks (VLSM) B.partial updates C.neighbor discovery mechanism D.multiple vendor compatibility

Answer: D EIGRP is a Cisco-proprietary routing protocol, and does not support multiple vendor environments. EIGRP is a classless routing protocol, and thus supports variable length subnet masks (VLSM). EIGRP routers build a neighbor table in memory, and use a multicast-based neighbor discovery mechanism. EIGRP routers send partial updates when there are network events.

What command disables 802.1x authentication on a port and permits traffic without authentication? A.dot1x port-control disable B.dot1x port-control force-unauthorized C.dot1x port-control auto D.dot1x port-control force-authorized

Answer: D Explanation: The command dot1x port-control force-authorized is used to disable 802.1x on a port and permit traffic without authentication. Dot1x ports are in one of two states, authorized or unauthorized. Authorized ports permit user traffic to flow through the port. This state usually follows successful authentication. Unauthorized ports only permit authorization traffic to flow through the port.

A new trainee is setting up a router in a test lab, and he asks you to describe the use of the connector marked BRI on the router. Which is a correct use for this connecter? A.Cisco 200-105 Exam "Pass Any Exam. Any Time." - www.actualtests.com 92 A WAN interface for a T1 connection B.A LAN interface to connect to a switch C.An interface to connect a console cable D.A WAN interface for an ISDN connection

Answer: D Explanation: The connector marked BRI is used for an Integrated Services Digital Network (ISDN) connection, specifically a basic rate interface (BRI). An ISDN basic rate interface provides three channels: a D channel for control signaling, and two B or bearer channels for data, resulting in 128 bits of bandwidth.

Which Cisco Internetwork Operating System (IOS) command is used to view the VLAN Trunking Protocol (VTP) statistics information? A.show vtp status B.show vtp domain C.show vtp statistics D.show vtp counters

Answer: D The show vtp counters command is used to view VTP statistics information. The syntax of the command is as follows: show vtp {counters | status} The parameters used in the command are counters, which specifies VTP statistics information, and status, which specifies VTP domain status information.

What is the default Administrative Distance (AD) value for an Enhanced Interior Gateway Routing Protocol (EIGRP) summary route? A. 1 B. 5 C. 90 D. 20 Answer: B

Answer:B Because: EIRGP summary route is 5. Internal EIRGP is 90. The default Administrative Distance (AD) value for an Enhanced Interior Gateway Routing Protocol (EIGRP) summary route is 5. The following table shows the AD values for different protocols and their IP routes: Routing Protocol Administrative distance Directly connected interface 0[a][5] Static route out an interface 1[b] Static route to next-hop address 1 DMNR - Dynamic Mobile Network Routing 3 EIGRP summary route 5 External BGP 20 Internal EIGRP 90 IGRP 100 OSPF 110 IS-IS 115 Routing Information Protocol (RIP) 120 Exterior Gateway Protocol (EGP) 140 On Demand Routing (ODR) 160 External EIGRP 170 Internal BGP 200 Unknown and unused 255[c]

QUESTION NO: 53 Which of the following are port roles in the Rapid Spanning Tree Protocol (RSTP)? (Choose three.) A.Alternate B.Listening C.Routing D.Designated E.Backup F.Blocking G.Discarding

Answers: A, D, E There are five port roles in RSTP: - Root port: the closest port to the root bridge in terms of path cost. There can be only one root port on each switch, and the root switch is the only switch in the network that does not have a root port. - Designated port: a forwarding port to the root bridge. All versions of STP require each network segment to have only one path toward the root bridge, to avoid bridging loops in redundantly connected environments. All bridges connected to a given segment listen to one another's BPDUs and agree that the bridge that is sending the best BPDU is the designated bridge for the segment. - Alternate port: a blocking port that becomes the root port if the active root port fails. - Backup port: a blocking port that becomes the designated port if an existing designated port fails. - Disabled port: a disabled port has no role within the operation of spanning tree.

You are configuring Open Shortest Path First (OSPF) protocol for IPv6 on Router5. The router has two interfaces, which have been configured as follows: S0/0 - 192.168.5.1/24 S0/1 - 10.0.0.6/8 You would like OSPF to route for IPv6 only on the S0/0 network. It should not route for IPv6 on the S0/1 network. The process ID you have chosen to use is 25. You do not want to apply an IPv6 address yet. Which of the following command sets would enable OSPF for IPv6 as required?

The correct command sequence would be as follows: Router5(config)# ipv6 unicast-routing Router5(config)# ipv6 router ospf 25 Router5(config-rtr)# router-id 1.1.1.1 Router5(config)# interface S0/0 Router5(config-if)# ipv6 ospf 25 area 0
