F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 90

An LTM HTTP pool has an associated monitor that sends a string equal to 'GET /test.html'.
Which two configurations could an LTM Specialist implement to allow server administrators to disable their pool member servers without logging into the LTM device? (Choose two.)

Answer options

• A. Set monitor to transparent and ask the server team to set string ‘TRANSPARENT’ in test.html.
• B. Set ‘receive string’ equal to 'SERVER UP and ask the server team to set string ‘SERVER DOWN’ in test.html.
• C. Set ‘alias’ equal to 'SERVER DOWN’ and ask the server team to set string ‘SERVER DOWN’ in test.html.
• D. Set ‘receive disable string’ equal to 'SERVER DOWN’ and ask the server team to set string ‘SERVER DOWN’ in test.html.
• E. Set ‘disable pool member’ equal to 'SERVER UP’ and ask the server team to set string ‘SERVER DOWN’ in test.html.

Correct answer: B, D

Explanation

Option B is correct because setting the ‘receive string’ to 'SERVER UP' allows the monitor to recognize when the server is active, while the string 'SERVER DOWN' will indicate when it should be disabled. Option D is also correct as setting ‘receive disable string’ to 'SERVER DOWN' enables the server team to control the pool members' status without LTM access. The other options do not provide a reliable method for server administrators to disable the pool members effectively.
