Router R1 connects to a Frame R

Router R1, a branch router, connects to the Internet using DSL. The engineer plans to use a configuration with a dialer interface. The answers list a feature and interface on which the feature could be configured.Which combinations accurately describe the interface under which a feature will be configured?（）

A. PPP on the ATM interface

B. VPI/VCI on the dialer interface

C. IP address on the ATM interface

D. CHAP on the dialer interface

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

根据网络拓扑和需求说明，完成路由器R1的配置。

R1(config)# interface Serial 1/0

R1(config-if)# ip address （3） 255.255.255.0 （设置串口地址）

R1(config-if)#no shutdown （开启串口）

R1(config)#interface FastEthernet0/0

R1(config-if)#ip address （4） 255.255.255.0 （设置以太口地址）

R1(config-if)#exit

R1(config)#router ospf 1

R1(config-router)#network 192.0.0.1 （5） area 0

R1(config-router)#network 192.1.1.1 （6） area 0

A. Router R1 will deny the 172.16.1.0/26 route while permitting the 172.16.1.64/27 route to be advertised.

B. Router R1 will advertise both rou tes.

C. Router R1 should be reconfigured with an ACL instead of an ip prefix - list command.

D. Router R1 will deny the 172.16.1.0/27 route while permitting the 172.16.1.0/26 route to be advertised.

A. The i su 10.1.0.0/23 route is a suppressed route.

B. The i su 10.1. 0.0/23 route is a summary route.

C. The i su 10.1.0.0/23 route is an IS - IS external route.

D. The R1 IS - IS router is an ASBR.

E. The R1 IS - IS router is an ABR that belongs to multiple IS - IS areas.

F. The R1 IS - IS router is performing route aggregation and is suppressing the more specific 10.1.0.0/23 prefix.

Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten PVCs associated with the subinterface.What command would make this router not use a DR, and dynamically discover OSPF neighbors?（）

A. ip ospf network broadcast

B. ip ospf network non - broadcast

C. ip ospf network point - to - multipoint

D. ip ospf network point - to - multipoint non - broadcast

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2? （）

A. Add the area 1 stub command on routers R1.

B. Add the always keyword to the default - information originate configuration command on router R2.

C. Remov e the default information originate configuration command from router R2 and place it on router R1.

D. Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.
