F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 93

What is the effect of an iRule error such as referencing an undefined variable?

Answer options

• A. The iRule execution will continue with the next statement.
• B. The execution of the current event within the iRule will be terminated.
• C. The iRule execution will be terminated, and both the client and server side connections will be reset.
• D. The connection will continue, but the iRule will NOT be executed again for the lifetime of the connection.

Correct answer: C

Explanation

The correct answer is C because when an iRule encounters a critical error, such as referencing an undefined variable, it leads to the termination of the iRule execution and resets both the client and server connections. Option A is incorrect as execution does not continue; option B is misleading since it does not cover the connection reset; option D is false because it implies the iRule could still execute later, which is not the case.
