  1. A
    The system ID of R1 is ee8c.a0c2.bafl
  2. B
    R1 has both leve1-1 and level-1-2 link state information
  3. C
    R1 only has link state information for leve1-2
  4. D
    In the leve1-2 network, there are a total of 8 routers

Correct Answer:
A

Question #24
In the network shown in the figure below, if you want to implement a remote LDP session between SWA and SWC, which statement is correct?
  1. A
    No need to specify the lsr-id of the correct equivalent
  2. B
    The configuration in the figure can be achieved
  3. C
    Need to create a remote peer, and then specify the lsr-id of the peer
  4. D
    Need to be equipped with a straight connection port to establish a TCP connection

Correct Answer:
C

Question #25
As shown in the figure, MPLS/BGP IPVPN is deployed in the network. The MP-BGP neighbor relationship is established between PE1 and PE2 through the LoopbackD interface. After the configuration is completed, it is found that CE1 and CE2 cannot learn routes from each other. Use the command on PE2 to query neighbor information as shown in the figure. What is the most likely cause of the problem?
  1. A
    The VPN instance parameters on PE1 or PE2 are incorrectly configured
  2. B
    PE1 and PE2 are not enabled with neighbors in the BGP-VPN4 unicast address family view
  3. C
    The LSP tunnel between PE1 and PE2 is not established
  4. D
    The routing protocol configuration between PE1 or PE2 and the respective CE is incorrect

Correct Answer:
B

Question #26
