The ABR in a Totally Stubby area will not advertise Type-3, Type-4, and Type-5 LSAs to the Totally Stubby area. Instead, the ABR will advertise a default route to the Totally Stubby area to guide forwarding of packets destined for other areas.
What is the maximum bits of a Class C address can be used for subnet?
Which of the following statements about the setup of a BFD session are true? (Choose three.)
A. A BFD session can be set up in either static or dynamic mode.
B. A static BFD session is set up by manually configuring BFD session parameters and delivering requests for setting up a BFD session. BFD session parameters include the local and remote discriminators.
C. A dynamic BFD session is set up by dynamically allocating local discriminators.
D. Static and dynamic BFD sessions are not differentiated.
Which of the following statements about the Smart Link group is false?
A. A Smart Link group has two interfaces at most. The two interfaces if configured are an active interface and a standby interface.
B. Among the two interfaces in a Smart Link group, one is in the active state and the other one in the standby state in normal situations.
C. When the active interface goes down, the Smart Link group automatically blocks it and changes the status of the standby interface to active.
D. When the active interface recovers from a fault, traffic will be switched back to it immediately.
Different from a Stub area, an NSSA supports Type-5 LSAs.
Which of the following are characteristics of a high availability network? (Choose two.)
A. Faults seldom occur.
B. Services can be quickly restored when a fault occurs.
C. Faults never occur.
D. Services can only be manually restored when a fault occurs.
Which of the following statements about NSSA commands is false?
A. If the default-route-advertise parameter is set, a Type-7 default route is generated.
B. The no-import-route parameter is used to prevent the importing of AS external routes in the form of Type-7 LSAs into an NSSA.
C. The no-summary parameter is used to prevent the advertisement of Type-3 and Type-4 LSAs in an area.
D. The set-n-bit parameter indicates that an N-bit will be set in a DD packet.
Which of the following Statement is false?
A. The OSPF Router ID of the local router is 126.96.36.199.
B. The OSPF Router ID of the neighbor is 188.8.131.52.
C. The OSPF Router ID of the neighbor is larger and thus the neighbor acts as a DR.
D. The local router acts as slave.
One class B network 184.108.40.206, the mask is 255.255.255.192. then subnet quantity available is ( ), the host quantity in every subnet at most is ()
The NBMA mode requires all the routers in the network to be fully connected; otherwise, it does not function.
