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
第3题:
VE1 is a switch in the Ezonexam network. Why will VE1 never learn the broadcast address?
A. Broadcast frames are never sent to switches
B. A broadcast frame. is never forwarded by a switch
C. Broadcasts only use network layer addressing
D. A broadcast address will never be the source address of a frame
E. Broadcast addresses use an incorrect format for the switching table
F. None of the above
第4题:
OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? ()
A. The ip ospf network broadcast command should be configured on each Frame Relay interface
B. The ip ospf network non -broadcast command should be configured on each Frame Relay interface
C. Th e ip ospf priority value on the spoke routers should be set to 0
D. The ip ospf priority value on the hub router should be set to 0
E. The neighbor command should be configured under the OSPF routing process on all routers
第5题:
A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.
B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.
C. Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.
D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.
E. The Hello parameters on routers R1 and R2 do not m atch.
第6题:
A. area ID
B. router ID
C. loopback address
D. IP address of interface on broadcast network
第7题:
Refer to the exhibit. Two routers are connected by Frame Relay and are running OSPF bet ween them. Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem?()
A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcast
B. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - point
C. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3
D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253
