A. FALSE

B. TRUE

A. The ABR in the NSSA area will convert Type 7 LSA into Type 5 LSA, and inject the LSA into the backbone area, thereby flooding the entire OSPF domain

B. Type 3 LSAs are not allowed inside the NSSA area, nor are Type 4 and Type 5 LSAs allowed inside the area.

C. The ABR in the NSSA area will automatically inject a default route into the area, which is described by type 7 LSA

D. The NSSA area can import external routes without learning external routes from other areas of the 0SPF network

A. Two routers are configured with the same Router ID.

B. The dr-priority of the two directly connected interfaces is set to 0.

C. The two routers are set with different Process IDs

D. The sending intervals of Hello messages between the two routers are inconsistent.

E. The two directly connected interfaces use the p2p network type, but the IP packet with the destination IP address 224.0.0.6 is refused to be transmitted.

F. The two directly connected interfaces use different network types.

A. When configuring IS-IS on a Huawei router, by default, the global Level1 of the router is Level-1-2.

B. Level-1 router cannot establish adjacency relationship with Level-2 router

C. Level-1 routers can establish adjacency relationships with Level-1-2 routers.

D. The Level-2 LSDB only contains routing information for the area where the Level-2 router is located.

A. The default sending interval is 5 milliseconds

B. The default sending interval is 10 milliseconds

C. The default sending interval is 100 milliseconds

D. The default sending interval is 1000 milliseconds

A. Specific Group Queries

B. Specify source query

C. Querier Election

D. Members leave

A. Router ID

B. Area ID

C. DR priority of the interface

D. IP address of the interface

A. FALSE

B. TRUE

A. peer ignore

B. Peer connect-interface

C. peer ebgp-max-hop

D. peer as-number

A. Use the DUAL algorithm to build the shortest path tree

B. Support VLSM

C. Support neighbor authentication

D. Regular updates

A. Load sharing means that multiple VRRP backup groups undertake business at the same time

B. Multi-gateway load sharing is to achieve load sharing by creating multiple VRRP backup groups with virtual IP addresses and specifying different VRRP backup groups as gateways for different users

C. The basic principle and packet negotiation process of VRRP load balancing and VRRP backup are the same

D. The load sharing method needs to establish multiple VRRP backup groups, and the Master device of each backup group can be different.

A. Switch Trunk type ports

B. Switch Hybrid: type of port

C. Switch Access: Type of port

D. Serial interface of the router

A. FALSE

B. TRUE

A. OSPF itself has no confirmation mechanism, so 0SPP relies on the lower layer protocol, namely TCP confirmation.

B. OSPF LSA is regularly updated every 30 minutes

C. OSPF uses the Bellman-Ford algorithm, and each router runs the algorithm independently

D. OSPF floods an LSU every 5s
