Which of the following address prefix lists matches the default route?

• A.permit 0.0.0.0 0
• B.permit 255.255.255.255 0
• C.permit 255.255.255.255 0 less-eual 32

The messages that IS-IS periodically sends on broadcast network type links are ________.

• A.PSNP
• B.CSNP
• C.LSP
• D.IIH

Regarding the neighbor table in the OSPF protocol, the following statement is correct ________.

• A.The router will periodically send Hello packets to the neighbors in the neighbor table to check the status of the neighbors
• B.The neighbor table records all routers that have established neighbor relationships.
• C.The neighbor table of the router is related to area division. Each region maintains its own independent neighbor table
• D.If the neighbor's Hello message is not received within a certain time interval, the neighbor will be considered invalid. At the same time, the system starts the aging timer and deletes the neighbor immediately after the aging timer expires.

The advantages of DR/BDR election in OSPF protocol include ______.

• A.After the DR fails, the BDR becomes the DR immediately, which can reduce the convergence time after the route change
• B.The router with the highest stability becomes the DR/BDR, which can enhance the robustness of the network
• C.Reduced number of adjacencies maintained

Running the command on the router and its display information is as follows:
<RTA>displaisis peer
