Refer to the exhibit. How long will the persistence record remain in the table?
The correct answer is D. 300 seconds after the last packet. The persistence record will remain in the table for 300 seconds, with the timer resetting after each new packet, effectively acting as an idle timeout.

Why each option
The persistence record will remain in the table for 300 seconds, with the timer resetting after each new packet, effectively acting as an idle timeout.
This choice suggests a 180-second idle timeout, which contradicts the assumed 300-second timeout value implied by the correct answer for the persistence record.
This implies a 180-second absolute timeout from the initial entry, which is a different timeout mechanism and value than the idle timeout and duration inferred from the correct answer.
This implies a 300-second absolute timeout from the initial entry, which is a different timeout mechanism than the idle timeout typically used for maintaining active session persistence.
Persistence records in F5 BIG-IP are often configured with an idle timeout, meaning the record's lifetime is extended for the specified duration (e.g., 300 seconds) after the last received packet from the client, ensuring active sessions remain persistent.
