3.1 CCNA 3 - Module 3

1	Which Layer 4 protocol does EIGRP use to provide reliability for the transmission of routing information? DUAL IP PDM RTP TCP UDP
2	Which of the following statements describes the bounded updates used by EIGRP? Bounded updates are sent to all routers within an autonomous system. Partial updates are sent only to routers that need the information. The updates are sent to all routers in the routing table. Updates are bounded by the routers in the topology table.
3	What is the EIGRP term for a backup route? backup route default route feasible successor route gateway secondary route successor route
4	Why would it be necessary to configure the bandwidth setting on an EIGRP interface rather than leaving it at the default setting? (Choose two.) A suboptimal route may be chosen as the best path to a destination if the bandwidth setting is higher than the actual bandwidth of the link. The network may be unable to converge if the bandwidth setting does not match the actual bandwidth of the link. Routing updates might arrive too fast for the interface to handle and be discarded because of buffer overflow. The configured bandwidth must match the actual speed of the link so the link will operate properly. Setting the bandwidth to a higher rate will optimize the effective throughput of the link.
5	If an EIGRP route goes down and a feasible successor is not found in the topology table, how does DUAL flag the route that has failed? recomputed passive active down unreachable successor
6	What tables does EIGRP maintain for each routed protocol it supports? (Choose three.) adjacency table topology table neighbor table routing table link state table ARP table
7	In which of the following tables does the EIGRP DUAL algorithm store the primary route to a destination? (Choose two.) routing topology neighbor path shortest path
8	Which of the following are found in the EIGRP neighbor table? (Choose two.) routes installed by DUAL lowest calculated metric to each destination network layer address of the neighbor routers number of EIGRP packets waiting to be sent feasible distance to each neighbor
9	Which of the following router commands is recommended only for troubleshooting specific types of network problems, not for monitoring normal network operation? show list debug terminal monitor
10	Which EIGRP command is used to view all routes that are known by the router? show ip eigrp interfaces detail show ip eigrp traffic show ip eigrp neighbors show ip eigrp topology all-links
11	What is the default administrative distance of EIGRP internal routes? 70 90 100 110 120 255
12	What is the advantage of routers forming adjacencies when using EIGRP? (Choose three.) Neighbor routers can quickly take over for a router that is in passive mode. New routers and their routes can quickly be discovered by neighbor routers. A router can share routing loads with neighbor routers. A router can quickly discover when a neighbor router is no longer available. Changes in network topology can quickly be shared with neighbor routers. Neighbor routers can save overhead by sharing their DUAL databases.
13	Which of the following types of routes will be denoted by EX in EIGRP routing table entries? (Choose two.) routes learned from other routing protocols routes learned from any non-adjacent EIGRP routers any route with a hop count metric higher than 224 EIGRP routes that originate in different autonomous systems all passive routes in the routing table
14	Which command will help identify established OSPF neighbor adjacencies? router# show ospf neighbor router# debug neighbor events router# debug ip ospf neighbor router# show ip ospf neighbor
15	Which command will display only the current EIGRP routing table entries? Router# show ip route Router# show ip route eigrp Router# show eigrp route Router# show eigrp protocol
16	Host 192.168.1.66 in the network illustrated is unable to ping host 192.168.1.130. How must EIGRP be configured to enable connectivity between the two hosts? (Choose two.) R1(config-router)# network 192.168.1.128 R1(config-router)# auto-summary R1(config-router)# no auto-summary R2(config-router)# no auto-summary R2(config-router)# auto-summary R2(config-router)# network 192.168.1.64
17	What information is maintained in the EIGRP topology database for a destination route? (Choose three.) the routing protocol the feasible distance of the route the highest cost of the route the SRTT value for the route the route cost as advertised by the neighboring router the physical address of the gateway interface
