What types of LSAs must a router running OSPFv3 generate? (Multiple choice)
- A . Network-LSA
- B . Link-LSA
- C . Intra-Area-Prefix-LSA
- D . Router-LSA
The network logic architecture of a cutover project is shown in the figure. The purpose of the cutover is to expand a network device R4 between R2 and R3. The OSPF protocol runs between the network devices.
After the physical network is connected, when performing the cutover operation, the network engineer first mistakenly imports the backup configuration of R3 into R4. Based on this scenario, which of the following descriptions are correct? (Multiple choice)
- A . R3 and R4 can establish an OSPF neighbor relationship
- B . The OSPF neighbor relationship between R1 and R2 is not affected
- C . R1 and R3 can establish an OSPF neighbor relationship
- D . R2 and R4 can establish an OSPF neighbor relationship
In a BGP/MPLS IP VPN network, routing between CE and PE devices can only be established through IGP or BGP protocol.
- A . True
- B . False
In the IS-IS IPv6 network shown in the figure, check the LSDB on R1. From the output information, it can be inferred that R1 is the DIS.
- A . True
- B . False
In the OSPFV3 network shown in the figure, OSPFv3 is enabled on the interconnected ports of R1, R2, and R3, and IPv6 global unicast addresses are configured. R1 and R3 are DRs, so both R1 and R3 will generate Intra Area-Prefix-LSA.
- A . True
- B . False
In the enterprise network shown in the figure, R3 is connected to the enterprise network management server, and all devices in the network communicate with the network management server through VPN.
During the inspection, it was found that R3 had redundant RT configurations. Which of the following commands can be executed on R3 to delete the redundant RTs without affecting the connectivity of all devices and the network management server? (Multiple choice)
- A . undo vpn-target 1:3 import-extcommunity
- B . undo vpn-target 3:1 import-extcommunity
- C . undo vpn-target 1:3 export-extcommunity
- D . undo vpn-target 2:3 export-extcommunity
Network maintenance can be divided into two categories: daily maintenance and troubleshooting. If the maintenance personnel have a high level of technical skills, they can maintain the network based on experience without following operating specifications.
- A . True
- B . False
As shown in the figure, an administrator has enabled the port isolation function on the interface of the switch connected to the terminal. In this scenario, which of the following IP addresses cannot be pinged by PC1?
- A . 10.1.1.3
- B . 10.1.1.5
- C . 10.1.1.1
- D . 10.1.1.4
For the OSPF network shown in the figure, please drag the values on the left to the correct position so that the traffic from PC1 to PC2 is PC1-R1-R3-R2-PC2; the traffic from PC2 to PC1 is PC2-R2-R1-PC1.
Use "display ospfv3 peer verbose" to view OSPFv3 neighbor information. In the output information, you can see the peer’s Router ID, the global unicast address of the peer’s interface, the neighbor’s status, and other content.
- A . True
- B . False
