F5-CTS-LTM BIG-IP Local Traffic Manager Practice Question
Which monitoring method is most reliable for verifying that a web application is not just responding to TCP requests, but also returning correct application-layer data?
⚠ Common exam trap
Candidates often select TCP monitors because they are 'easier' to configure, ignoring that a TCP monitor only checks if a port is open, not if the application is actually working.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
HTTP monitor
The HTTP monitor is specifically designed to perform application-layer verification by sending an actual HTTP request and waiting for a specific response string. This goes beyond simple TCP port checks, ensuring that the application server is fully functional, the web service is running, and the expected content is being served, which is vital for preventing 'false-up' states for failing web applications.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ICMP monitor
Why it's wrong here
The ICMP monitor only confirms that the server is reachable at the network layer via ping. It cannot verify that the web service is listening, that the application is running, or that the content is valid. A server could respond to ICMP while its web server service is completely dead.
- ✗
TCP monitor
Why it's wrong here
The TCP monitor only verifies that the specified port is open and accepting connections. It does not perform an application-layer handshake or check for valid HTTP content. A web server might be stuck in a loop or returning 500 errors, but the TCP port would still show as open.
- ✓
HTTP monitor
Why this is correct
The HTTP monitor sends a GET request to the target server and validates the response against a configured string. This provides high-fidelity monitoring by ensuring the web server is not only reachable and accepting connections but also actively serving correct application data, which is essential for maintaining service availability.
- ✗
SNMP monitor
Why it's wrong here
SNMP monitoring is typically used for gathering system-level metrics like CPU and memory usage from a server. It is not an appropriate tool for health checking the availability of a specific web application, as it does not simulate the end-user experience of browsing to the site and receiving data.
