The routers named Testking1 and Testking2 are both configured with RIP only.What will happen in the event of Testking1 receiving a routing update that contains a higher cost path to a network already in its routing table?（）
第1题：
The Testking router is running both RIP and IGRP, and the same route is learned by this router from both of these methods. However, when you issue the command"show ip route" you see only the IGRP route, and not the RIP route. Why is this?（）
A. IGRP has a faster update timer.
B. IGRP has a lower administrative distance.
C. RIP has a higher metric value for that route.
D. The IGRP route has fewer hops.
E. The RIP path has a routing loop.
第2题：
A. Passiveroutes are in the process of being calculated by DUAL.
B. EIGRP supports VLSM, route summarization, and routing update authentication.
C. EIGRP exchanges full routing table information with neighboring routers with every update.
D. If the feasible successor has a higher advertised distance than the successor route, it becomes the primary route.
E. A query process is used to discover a replacement for a failed route if a feasible successor is not identified from the current routing information.

The routers named Testking1 and Testking2 are both configured with RIP only.What will happen in the event of Testking1 receiving a routing update that contains a higher cost path to a network already in its routing table?（）
A. The update information will be added to the existing routing table.
B. The update information will replace the existing routing table entry.
C. The update will be ignored and thus no further action will occur.
D. The existing routing table entry will be purged from the routing table and all routers will attempt convergence.
第4题：
A.If RIPv2 is the routing protocol, only the path AD will be installed in the routing table by default.
B.If RIPv2 is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.
C.If EIGRP is the routing protocol, only the path AD will be installed in the routing table by default.

B. Incorrectly configured IP addresses
C. IGRP is incorrectly configured.
D. Frame relay is not configured.

D. It uses the DUAL algorithm to determine the best route.
E. OSPF routers send the complete routing table to all directly attached routers.
F. OSPF routers discover neighbors before exchanging routing information.
第8题：
A RIP router has an entry in the routing table for a specific network destination. It then gets updated with another entry for that same destination, but with a higher path cost (hop count) than the one already in the routing table.What will the router do in this situation?（）
A. It will ignore the update and take no further action.
B. It will add the update information to its routing table.
C. It will replace the existing routing table entry with the update information.
D. It will delete the existing routing table and will send out hello packets to rebuild the routing table.
第9题：

● One of the most widely used routing protocols in IP networks is the Routing Information Protocol (RIP). RIP is the canonical example of a routing protocol built on the （71）algorithm. Routing protocols in internetworks differ slightly from the idealized graph model. In an internetwork, the goal of the routers to forward packets to various （72）.
Routers running RIP send their advertisement about cost every （73） seconds. A router also sends an update message whenever an update from another router causes it to change its routing table.
It is possible to use a range of different metrics or costs for the links in a routing protocol. RIP takes the simplest approach, with all link costs being equal （74）. Thus it always tries to find the minimum hop route. Valid distances are 1 through （75）.This also limits RIP to running on fairly small networks.
（71）
A. distance vector
B. link state
C. flooding
D. minimum spanning tree
（72）
A. computers
B. routers
C. switches
D. networks
（73）
A. 10
B. 30
C. 60
D. 180
（74）
A. 1
B. 15
C. 16
D. length of the link
（75）
A. 6
B. 10
C. 15
D. 16
