Which parameter should be configured on a GSLB virtual server to ensure a service continues to serve existing client requests after the service is manually disabled and then stops accepting new ones?

• A. Request Threshold
• B. Persistence Time-Out
• C. Persistence Threshold
• D. Wait Time

Answer: (B)

Persistence Time-Out is the setting that controls how long the system will honor the same client’s session with the originally chosen service after that service is disabled. This lets existing connections finish on the service they started on, even though new requests are no longer sent to it. If the timeout is too short, active requests could be dropped; if it’s too long, failover for new requests is unnecessarily delayed. The other options don’t govern how long to keep serving ongoing sessions: they relate to thresholds for triggering changes or delays in handling requests, not the duration of persistence for existing connections.
