F5 Application Delivery Fundamentals — Question 80

Which two statements are true concerning the default communication between a redundant pair of BIG-IP systems? (Choose two.)

Answer options

• A. Synchronization occurs via a TCP connection using ports 683 and 684.
• B. Connection mirroring data is shared via a TCP connection using port 1028.
• C. Persistence mirroring data is shared via a TCP connection using port 1028.
• D. Connection mirroring data is shared through the serial failover cable unless network failover is enabled.

Correct answer: B, C

Explanation

The correct answers, B and C, are accurate because both connection and persistence mirroring data utilize port 1028 for communication. Option A is incorrect as it incorrectly states the ports used for synchronization, while option D is misleading as it suggests that connection mirroring occurs via the serial failover cable without mentioning the specific conditions under which this is true.
