QUESTION 81 You work as a network administrator at Cisco Highway. A router in the Cisco Highway network is configured for EIGRP. You want to suppress the router from sending routing updates out the Serial 0/0 interface. It is necessary for the router to form and maintain neighbor adjacencies on the interface. The router has already been configured as follows: Router(config)#access-list 20 deny any Router(config)#access-list 100 permit ip any any Router(config)#router eigrp 1
Answer:
Explanation: We do not want to allow the routing updates along serial 0 to go out. The distribute list command is denying the ip traffic.
QUESTION 82 You are the network administrator at Cisco Highway. The router topology for the Cisco Highway network is shown in the following exhibit: You configure Cisco HighwayZ with the following commands: interface serial 0 encap frame relay Which command will complete an EIGRP hybrid multipoint configuration on Cisco HighwayZ S0?
A. bandwidth 56
B. bandwidth 224
C. bandwidth 256
D. bandwidth 512 Answer: B Explanation: Configuring Bandwith over a Hybrid Multipoint Network If the multipoint network has differing speed allocated to the VCs, a more complete solution is needed. There are two main approaches
1. To take the lowest CIR and to simply multiply this by the number of circuits. This is applied to the physical interface. The problem with this configuration is that the higher bandwidth Links will be under utilized for some things. Reference: CCNP Self-Study, CCNS, P BSCI Exam, Certification Guide Clare Gough, Page 484
QUESTION 83 Given the following configuration: interface serial 0 ip policy route-map demo route-map demo permit 10 match ip address 4 set interface serial2 serial3 access list 4 permit 10.3.3.2 0.0.0.0 Which of the statements below about a packet arriving on serial 0 would be true?
A. If the packet is destined for 10.3.3.2, it will be routed out interface serial 2 and interface serial 3 by means of load-sharing.
B. If the packet is sourced from 10.3.3.2, it will be susceptible to fast-switching policy routing.
C. If the packet is sourced from 10.3.3.2, it will be routed out interface serial 2, unless it is not up, in which case it will be routed out interface serial 3.
D. If the packet is sourced from 10.3.3.2, the flow will be routed out interface serial 2 and interface serial 3 by means of load sharing for the duration of the flow. Answer: C Explanation: The set command specifies the list of interfaces which may be used to forward the traffic. If the first interface goes down, the second interface is being used.
QUESTION 84 You are the network administrator at Cisco Highway. You want to configure a Cisco router for the IS-IS protocol. You want to configure Integrated IS-IS to route IP in particular. What must you do? would you apply the command shown in the exhibit above?
A. Issue the ip router isis command in line configuration mode.
B. Issue the ip router isis command in router configuration mode.
C. Issue the ip router isis command in global configuration mode.
D. Issue the ip router isis command in interface configuration mode.
E. Issue the ip router isis command in local configuration mode. Answer: D Explanation: ip router isis is a command specified in the interface configuration mode. ip router isis To configure an IS-IS routing process for IP on an interface, use the ip router isis interface configuration command. To disable IS-IS for IP, use the no form of this command. ip router isis [tag] no ip router isis [tag] Reference: http://www.cisco.com/en/US/products/sw/iosswrel/ps1826/products_command_summary_chapter09186a00800 d9c5a.php#xtocid60144
QUESTION 85 You work as a technician at Cisco Highway. The company's network consists of a hub and spoke topology that carries 24 remote offices. The router at the head quarters in Quebec is called Router Cisco Highway1. Point-to-multipoint Frame Relay EIGRP network is in operation between the headquarters and its remote offices. None of the CIR for each Frame Relay PVC connection is similar and there is no bandwidth command configured under any of the interfaces on router R1. What could you to do counter potential EIGRP packet pacing problems due to the different CIR each PVC connection has?
A. Convert each Frame Relay PVC to point-to-multipoint connection.
B. Convert each Frame Relay PVC to point-to-point connection and also manually configure the bandwidth of 64 kbps for each of these PVC connections.
C. Configure the bandwidth of the major interface to 1.544 Mbps manually.
D. Convert each Frame Relay PVC to point-to-point connection and also manually configure the bandwidth to equal to the respective CIR for each of these PVC connections. Answer: D Explanation: Since the CIR for each interface is different and there is no bandwidth command being used, it is necessary to convert each Frame Relay to point-to-point connection and manually configure the bandwidth to equal to the respective CIR for each of these PVC connections.
QUESTION 86 You work as a technician at Cisco Highway. Cisco Highway has a branch office that is attached to a central office. Your aim is to have the central office learn all routes in the branch office. But you do not want a situation where the branch office learns all routes from the central office. What is the most scalable option you should use on the branch office router if all routes from the central office are filtered?
A. Configure the interface connected to the central office as a passive interface that blocks incoming updates.
B. Configure a default route pointing to the networks behind the central office router.
C. Enable route update filtering on the interface connected to the central office to block incoming updates.
D. Configure static routes pointing to the networks behind the central office router. Answer: B
QUESTION 87 You are a technician at Cisco Highway. You inform your newly appointed Cisco Highway trainee that you can expect problems in a situation where a single OSPF area has too many routers. Your trainee now wants to know what these problems are. What would your reply be? (Choose all that apply.)
A. Routing table recalculation too frequent.
B. Excessive LSA traffic.
C. Adjacencies table recalculation more frequently.
D. Too many reachability errors. Answer: A, B
QUESTION 88 Which of the following features is typical of an IS-IS backbone?
A. A router in every areas.
B. An unbroken string of L1 and LS IS-IS routers.
C. A chain of L2 and L1/L2 IS-IS routers.
D. A central area to which all other areas are attached.
E. All routers in a single area. Answer: C Explanation: L1 routers are internal to the area and so only L2 and L1/L2 routers form the backbone in IS-IS.
QUESTION 89 You are a network technician at Cisco Highway. Your newly appointed Cisco Highway trainee wants to know which of the following qualify to be called EIGRP reliable packets. What would your reply be? (Choose all that apply.)
A. hello
B. ACK
C. reply
D. query
E. update Answer: C, D, E
Explanation: In EIGRP, the reliable packets are reply, query and update.
QUESTION 90 Which of the following statements would best describe the backbone area in an IS-IS domain?
A. A contiguous collection of L1 routers.
B. A contiguous collection of L2 routers.
C. A contiguous collection of L1/L2 routers.
D. A contiguous collection of L1 and L1/L2 routers.
E. A contiguous collection of L2 and L1/L2 routers. Answer: E Explanation: In IS-IS the backbone is a collection of L2 and L1/L2 routers. Back bone is made up of L1/L2 and L2 routers. Only L2 are backbone type. Source: BSCI Self Study Cisco Press (2003) 2nd Edition, P182.
