B. The source IP address and source port number of the local end are inconsistent with the destination IP address and destination port number of the peer.

C. The number of retransmissions of the primary and backup service packets is different from the retransmission interval.

D. The TCP channel sent by the active and standby mechanism packets is not established.

Correct Answer: B,C,D

Question 3

A. Correct

B. False

Correct Answer: B

Question 4

Correct Answer: B

Question 8

Which of the following statements about Option 43 in the N+l backup networking are TRUE? (Multiple Choice)

A. If the AC with the IP address carried in Option 43 does not respond, the AP fails to discover the AC.

B. The command for setting Option 43 on the DHCP server to IP addresses of the active and standby ACs is option 43 sub-option 2 ip-address ip-address &<l-8>.

C. After Option 43 is configured, the AP only unicasts Discovery Request messages to the AC's IP addresses carried in Option 43.

D. When configuring Option 43, you need to specify IP addresses of the active and standby ACs for the AP, and IP addresses of the other active ACs.
