Refer to the exhibit. During maintenance, the BIG-IP Administrator manually disables a pool member as shown. What is the result?

The correct answer is A. All pool members continue to process persistent connections. When a pool member is manually disabled, it stops accepting new connections but continues to process any existing and persistent connections to maintain session integrity.

Why each option

When a pool member is manually disabled, it stops accepting new connections but continues to process any existing and persistent connections to maintain session integrity.

AAll pool members continue to process persistent connectionsCorrect

Disabling a pool member in a BIG-IP system prevents it from accepting new connections but allows it to gracefully complete existing and persistent connections. This ensures that ongoing user sessions that have established persistence are not abruptly terminated.

BAll pool members stop accepting new connections.

This statement is incorrect because only the disabled pool member stops accepting new connections, not all pool members in the pool.

CThe disabled pool member stops processing persistent connections.

This statement is incorrect because a disabled pool member continues to process persistent connections until they naturally expire or are terminated by the client.

DThe disabled pool member stops processing existing connections

This statement is incorrect because a disabled pool member continues to process existing connections, allowing for a graceful shutdown without interrupting active sessions.
