IP routing protocols， such as OSPF and Enhanced EIGRP， are used primarily in network designs that contain entry and exit points to the network from service providers. What is a common trait of IP routing  protocols？（）  A、 They add needed overhead in small

A.No dynamic interior routing protocol can summarize as shown

B.Unless configured otherwise, EIGRP would automatically summa rize the prefixes as shown in the exhibit

C.With this IP addressing scheme, EIGRP can be manually configured to summarize prefixes at the specified summarization points

D.The IP address design lends itself to OSPF Each summarizing router would be an ABR, summarizing to the next area in the address hierarchy

A. The ip classless command is enabled by default in recent versions of IOS.

B. The ip classless command should only be enabled when static routing is being used instead of a routing protocol.

C. The ip classless command should be enabled by the network administrator whenever RIPv1 or IGRP is being used.

D. The ip classless command should be enabled by the network administrator whenever OSPF, RIPv2, or EIGRP is being used.

A.lower administrative overhead

B.increased network availability

C.greater network scalability

D.easier to implement qualified next hops

E.easier ECMP route implement

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.

D.If EIGRP is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.

E.If EIGRP and OSPF are both running on the network, the EIGRP paths will be installed in the routing table.

F.If EIGRP and OSPF are both running on the network, the OSPF paths will be installed in the routing table.

A. debug ip routing

B. show running-config

C. show ip route protocols

D. show ip protocols

E. show protocols al

A router leams about a remote network from EIGRP.OSPF. and a static route. Assuming all routing protocols are using their default administrative distance, which route will the router use to forward data to the remote network?（）

A. The router will use the static route.

B. The router will use the OSPF route.

C. The route will use the EIGRP route.

D. The router will load balance and use all three routes.

A. Distance vector protocols send the entire routing table to directly connected neighbors.

B. Distance vector protocols are responsible for sending updates to all networks listed in the routing table.

C. Link state protocols are responsible for sending the entire routing table to the whole network.

D. Link state protocols send updates regarding their own links status to all other routers on the network.

E. None of the above

Refer to the exhibit. The routing protocols EIGRP and OSPF have been configured as indicated in the exhibit. Given the partial configuration of router R2, which network will be present in th e routing table of R4?（）

A. Network B

B. Network A and Network B

C. Network A

D. neither Network A nor Network B

A.RIP v1

B.RIP v2

C.IGRP

D.OSPF

E.BGP

F.EIGRP

A.RIPV1 and OSPF are classless routing protocols.

B.Classful routing protocols send the subnet mask in routing updates.

D.EIGRP and OSPF are classful routing protocols and summarize routes by def……
