A) In the RIP protocol, the default-route originate command is used to generate a default route or send the default route in the routing table to the neighbor.
B) In the BGP protocol, the default-route imported command is used to enable the import of default routes into the BGP routing table.
C) In a static route, the ip route-static default-preference command is used to generate a default route on the current router.
D) In the OSPF protocol, the default-route-advertise command is used to advertise the default route to the common OSPF area.
2. Which of the following description is to verify whether a received hello message is legally wrong?
A) If the network type of the receiving port is point-to-point type or virtual link, the Network Mask field is not checked.
B) The E-bit in the Options field in the received Hello message must be consistent with the configuration of the related area.
C) The RouterDeadInteral field in the received Hello message must be consistent with the configuration of the receiving port.
D) If the network type of the receiving port is broadcast, point-to-multipoint or NBMA, the network mask field in the received Hello message and the interface can be inconsistent.
3. In a company network environment, there are two switches SWA and SWB. The link aggregation LACP mode is adopted between the SWA and the SWB. There are three links added to the link aggregation, and the maximum number of active links is set to two. The system priority of the SWA is 4096. The system priority of the SWB is 32768. The interfaces of the three SWA links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 10, 20, 30. The interfaces of the three SWB links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 30, 20, and 10 respectively.
Which of the following conclusions are correct? (Multiple choice)
A) SWB is active
B) SWB G0/0/2 and G0/0/3 are active interfaces
C) SWA G0/0/1 and G0/0/2 are active interfaces
D) SWA is active
4. Inject the route into BGP through the network command. Which of the following description is wrong? (Multiple choice)
A) The route must be IGP route.
B) The route must exist in the P routing table and is the best route
C) Match the prefix, the mask length does not have to be strictly matched.
D) The factory mask length must be strictly matched.
5. The following description about OSPF packet authentication, which is wrong?
A) When both the area authentication mode and the interface authentication mode exist, use area authentication first.
B) The authentication modes supported by AR2200 are classified into null, simple, MD5 and HMAC-MD5 based on the encryption algorithm.
C) Only authenticated OSPF packets are accepted. Otherwise, neighbors cannot be set up normally.
D) AR2200 supports two authentication modes: area authentication and interface authentication.
