F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 84

An LTM Specialist is investigating reports from users that SSH connections are being terminated unexpectedly. SSH connections are load balanced through a virtual server. The users experiencing this problem are running SQL queries that take upwards of 15 minutes to return with no screen output. The virtual server is standard with a pool associated and no other customizations.
What is causing the SSH connections to terminate?

Answer options

• A. UDP IP ToS
• B. TCP idle timeout
• C. The virtual server has no persistence.
• D. The pool has Reselect Retries set to 0.

Correct answer: B

Explanation

The correct answer is B, as TCP idle timeout settings can lead to the termination of long-lived connections when there is no data transfer for a specified period. Options A and D are not relevant to this issue, and option C would only affect session continuity if persistence was required, which isn't the case for SSH connections.
