F5 Application Delivery Fundamentals — Question 120

Assuming there are open connections through an active system's virtual servers and a failover occurs, by default, what happens to the connections?

Answer options

• A. All open connections are lost.
• B. All open connections are maintained.
• C. When persistence mirroring is enabled, open connections are maintained even if a failover occurs.
• D. Long-lived connections such as Telnet and FTP are maintained, but short-lived connections such as HTTP are lost.
• E. All open connections are lost, but new connections are initiated by the newly active BIG-IP, resulting in minimal client downtime.

Correct answer: A

Explanation

The correct answer is A because, by default, all open connections are indeed lost during a failover. Options B and C are incorrect as they suggest that connections are maintained, which is not the case unless specific configurations are set. Option D incorrectly categorizes the types of connections maintained, while option E inaccurately states that new connections are initiated without addressing the loss of existing ones.
