Options

• AAll open connections are lost.
• BAll open connections are maintained.
• CWhen persistence mirroring is enabled, open connections are maintained even if a fail over occurs.
• DLonglived connections such as Telnet and FTP are maintained, but shortlived connections such as HTTP
• EAll open connections are lost, but new connections are initiated by the newly active BIGIP, resulting in

Explanation

By default, when an active system experiences a failover, all open connections through its virtual servers are lost because the standby device does not have the connection state.

Common mistakes.

• B. Maintaining all open connections is not the default behavior; it requires specific configuration like connection mirroring.
• C. This choice describes the behavior with persistence mirroring (or connection mirroring) enabled, not the default behavior, which is the focus of the question.
• D. The type of connection (long-lived vs. short-lived) does not change the default behavior; all connections are lost unless connection mirroring is configured.
• E. While new connections are accepted by the newly active BIG-IP, the default outcome for existing connections is loss, and the statement about initiating new connections for lost ones is misleading.
