Module 5 – Exam 1. On multi-access segments, why do OSPF DROther routers remain in the 2WAY/DROTHER state? Select the BEST answer. Because they only exchange their databases with the DR and BDR routers Because they can only send updates to Multicast group 224.0.0.6 Because they are assigned a default OSPF priority of 0 Because they can only send updates to Multicast group 224.0.0.5 Because they are not allowed to send an LSAs Question 1 of 25 2. While the most common deployed trusted VPNs are Layer 3 VPNs, some service providers also provide Layer 2 VPN service for their customers using either Virtual Private LAN Service (VPLS) or Virtual Private Wire Service (VPWS) technologies. These technologies allow for the encapsulation of Layer 2 frames, e.g. Ethernet and Frame Relay, over MPLS or pure-IP networks. The primary difference between VPLS and VPWS is that VPLS provides point-to-multipoint connectivity while VPWS provides only point-to-point connectivity. False True Question 2 of 25 3. What feature of Link State protocols allows them to converge much faster than Distance Vector protocols? Select the BEST answer. No automatic summarization Shorter timer values No split horizon No hop count limitation Incremental updates Question 3 of 25 4.

What is used in Cisco IOS software to move packets or frames? Select the BEST answer. The switching protocol is used because it is faster and has lower latency than the routing protocol The switching protocol is used because it is faster and has lower latency than the routing protocol The routing process is used because it is faster and has lower latency than the switching process The switching process is used because it is faster and has lower latency than the routing process The routing protocol is used because it is faster and has lower latency than the switching protocol Question 6 of 25 7. There are current 6 OSPF-enabled routers connected to a multi-access segment. Router 6, with a RID of 6.6.6.6 has been elected DR and Router 5, with a RID of 5.5.5.5 has been elected BDR. A new router, Router 7, with a RID of 7.7.7.7 is added to the multi-access segment. What happens when Router 6 fails or is removed? Select the BEST answer. Router 7 assumes the role of DR because of the higher RID; Router 5 remains BDR Router 5 assumes the role of DR because it was the BDR; Ruoter 4 becomes BDR because it was next in line The network continues to run with just the BDR When the DR is removed or failed, all adjacecies are reset and a new election is held Router 5 assumes the role of DR because it was the BDR; Router 7 is elected BDR Question 7 of 25 8. Which of the following protocols is BGP most similar to? Select the BEST answer. IS-IS EIGRP RIP OSPF ODR Question 8 of 25 9. Which of the following is a valid ISATAP address? Select the BEST answer. 3FFF:ABCD:1234:A:0:5FFE:0101:0101 3FFF:ABCD:1234:A:0:5EEF:0101:0101 3FFF:ABCD:1234:A05FF:E0101 3FFF:ABCD:1234:A:5:FEFE:0101:0101 3FFF:ABCD:1234:A:0:5EFE:0101:0101 Question 9 of 25 10. Which of the following is not a routing algorithm goal or objective? Select the BEST answer. Flexibility Stability Rapid Convergence Suboptimal routing Ease of Use Question 10 of 25 11. Which of the following would not be a major consideration when planning on a tunneling implementation? Select the BEST answer. Protocol Filtering Network Address Translation ICMPv6 Error Messages Maximum Transmission Unit issues ICMPv4 Error Messages Question 11 of 25 12. When implementing PBR, what will the router do when the set ip default next-hop command is used? Select the BEST answer. If no explicit route entry for the destination network exists, the router drops the packets If only a default route is present in the routing table, the router will use that route It forces the router to check the Cisco Express Forwarding (CEF) database to determine if an entry is available for the next hop If the router has an explicit route to the specified network, it will use that route first and ignore the PBR configuration If the router does not have an explicit route to the specified destination network, it will use the PBR configuration Question 12 of 25 13. Click on the Exhibit. From the debug output in the exhibit, we can determine that Cisco Express Forwarding (CEF) is NOT enabled on the router. True False Question 13 of 25 14. While the MED value is only compared for prefixes received from the same AS, Cisco IOS software does allow MED values to be compared for prefixes received from different ASes using which of the following commands? Select the BEST answer. Using the bgp med-always-compare command Using the bgp bestpath always-compare-med command Using the bgp compare-med-always command Using the bgp always-compare-med command Question 14 of 25 15. What default community do all BGP prefixes belong to? Select the BEST answer. INTRANET DISCRETIONARY WELL-KNOWN INTERNET MANDATORY TRANSITIVE Question 15 of 25 16. When configuring PBR, what happens when the set interface command is specified in the route map, no cache entry exists and a FastEthernet interface is specified? Select the BEST answer. The router will check the CDP database to determine if an entry is available The router will discard the packets silently The router will use the default route to forward packets instead The router will discard the packets and sent out an ICMP error message The router will use a specific entry in the routing table to forward packets instead Question 16 of 25 17. Which of the following commands is used to apply PBR configuration globally on the router? Select the BEST answer. The ip local-policy route-map [name] command The ip policy route-map [name] local command The ip-local policy route-map [name] command The ip policy local route-map [name] command The ip local policy route-map [name] command Question 17 of 25 18. Which of the following statements about OSPF route filtering with distribute lists are FALSE? Select THREE answers. OSPF supports the use of distribute lists in the inbound direction only Distribute lists filter both the prefix and the associated LSA Distribute lists filter the prefix and but not the associated LSA OSPF supports the use of distribute lists in both the inbound and outbound direction OSPF supports the use of distribute lists in the outbound direction only Question 18 of 25 19. Click on the Exhibit. What type of VPN is illustrated in the exhibit? Selec the BEST answer. Internet-based Secure Intranet-based Extranet-based Hybrid Trusted Question 19 of 25 20. Which of the followinng EIGRP packets are sent RELIABLY? Select THREE answers. Request Hello Ack Update Reply Query Question 20 of 25 21. The _________________ attribute is defined as type code 7 and is an optional, transitive attribute. This attribute type identifies the BGP router that performed the route aggregation. AGGREGATE_ATOMIC ATOMIC_AGGREGATOR AGGREGATOR ATOMIC_AGGREGATE AGGREGATE Question 21 of 25 22. Which of the following will still allow an EIGRP neighbor relationship to be established between two routers? Select the BEST answer. Mismatched EIGRP Authentication Parameters Using the same router ID on both neighbors Mismatched EIGRP K Values Mismatched EIGRP Autonomous System (AS) Number Using secondary addresses for EIGRP neighbor relationships The neighbors are not on a common subnet Question 22 of 25 23. Which of the following is a major consequence of filtering LSAs in OSPF networks? Select the BEST answer. Neighbors will not be able to build complete routing tables It suppresses the unnecessary flooding of LSAs in stable topologies It makes the protocol more efficient It improves convergence in large OSPF networks It reduces the size of the LSDB Question 23 of 25 24. With _______________________, the router first copies the received packet to the system buffer. Next, the router performs a routing lookup for the destination. This is performed to determine the next hop and the output interface. The router then checks the ARP cache to determine the correct Layer 2 address for the next hop. Once the address has been determined, the frame is rewritten with the destination address and sent to the outgoing interface that is connected to that destination. The same switching path is then used for any other subsequent packets for that same destination. store-and-forward switching process switching fast switching optimum switching CEF switching Question 24 of 25 25. Which Cisco IOS switching mechanism uses a binary tree? Select the BEST answer. ARP switching Fast switching FIB switching Process switching CEF switching Question 25 of 25 Loading…
