Router R1 is configured as shown below: router eigrp 100 net

Refer to the exhibit. Routers R1 and R2 have established a neighbor relationship and are exchanging routing information. The network design requires that R1 r eceive routing updates from R2, but not advertise any routes to R2. Which configuration command sequence will successfully accomplish this task? （）

A. R1(config)# router eigrp 1 R1(config - router)# passive - interface serial 0

B. R1(config)# access - list 2 0 deny any R1(config)# router eigrp 1 R1(config - router)# distribute - list 20 out serial 0

C. R2(config)# access - list 20 permit any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 in serial 0

D. R1(config)# access - list 20 permit any R 1(config)# router eigrp 1 R1(config - router)# distribute - list 20 in serial 0

E. R2(config)# access - list 20 deny any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 out serial 0

F. R2(config)# router eigrp 1 R2(config - router)# passive - interface serial 0

B.Manual route summarization is configured in router configuration mode when the router is configured for EIGRP routing

C.Manual route summarization is configured on the interface

D.The ip summary - address eigrp command generates a default route with an administrative distance of 5

E.When manual summarization is configured, the summary route will use the metric of the largest specific metric of the summary routes

F.The ip summary - address eigrp command generates a default route with an administrative distance of 90

Router R1 has been configured with the redistribute ospf 1 route - map fred command under router eigrp 1. The route map named fred needs to be configured to match routes to d etermine which routes are redistributed into EIGRP.Which of the following answers lists an item that cannot be matched by route map fred?（）

A. Subnet number

B. Next - hop router IP address of the route

C. Whether the route is an E1 or E2 route

D. The ro ute‘s tag

E. The number of router hops between the router and the subnet

A. The route to 10.2.0.0/16 was redistributed into EIGRP.

B. A default route has been redistributed into the EIGRP autonomous system.

C. R1 is configured with the ip summary - address command.

D. R1 is sourcing a n external EIGRP route from Null0.

E. The router at 10.1.1.2 is configured with the ip default - network 0.0.0.0 command.

F. R1 is configured with the variance command.

A. Receive - only

B. Stub

C. Static

D. Summary

E. Connected

F. Dynamic

A.Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out inquiring for a second successor to network 10.6.1.0/24

B.Router R1 can send traffic destined for network 10.6.1.0/24 out of interface FastEthernet0/0

C.Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out before it declares the neighbor unreachable

D.Router R1 is waiting for a reply from the neighbor 10.1.2.1 in response to the query sent out about network 10 .6.1.0/24

Router R1 has a connected route for 10.1.1.0/24 off interface Fa0/0. Interface Fa0/0 has been enabled for OSPF due to a router ospf 1 and network 10.0.0.0 0.0.0.255 area 0 command. R1 also has EIGRP configured, with the redistribute ospf 1 metric 1000 100 10 1 1500 command configured under EIGRP.Which one of the following is true?（）

A. R1 will not redistribute 10.1.1.0/24 into EIGRP, because R1 knows it as a connected route and not as an OSPF route.

B. For any OS PF routes redistributed into EIGRP, the metric components includea value equivalent to 1 Mbps of bandwidth.

C. For any OSPF routes redistributed into EIGRP, the metric components include a value equivalent to 100 microseconds of delay.

D. No subnets of network 10.0.0.0 will be redistributed due to the omission of the subnets parameter.

A. The no auto - summary command has not been issued under the EIGRP process on both routers.

B. Interface E0 on router R1 has not been configured with a secondary IP address of 10.1.2.1/24.

C. EIGRP cannot exchange routing updates with a neighbor‘s router interface that is configured with tw o IP addresses.

D. EIGRP cannot form neighbor relationship and exchange routing updates with a secondary address.
