F5-CTS-LTM BIG-IP Local Traffic Manager Practice Question
An administrator wants to reduce the load on the backend servers by caching static content. Which BIG-IP feature should be configured?
⚠ Common exam trap
Candidates often look for a 'Caching' profile instead of the 'Web Acceleration' profile, which is the actual container for the caching functionality in modern BIG-IP versions.
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
✓
Apply a Web Acceleration profile with an enabled cache object.
The Web Acceleration profile provides built-in HTTP caching capabilities. By enabling this on a virtual server, the BIG-IP can cache static assets like images, CSS, and JS files, serving them directly from memory and significantly reducing the number of requests that reach the backend web servers. This is a highly effective way to improve application performance and scalability without modifying the backend application code.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable the 'OneConnect' profile to pool backend connections.
Why it's wrong here
OneConnect improves performance by reusing established connections to the backend servers, reducing the overhead of repeated TCP handshakes. While it helps with connection efficiency, it does not cache content or reduce the actual request volume hitting the backend servers, which is the primary goal for offloading static content processing.
- ✗
Create an iRule to store request data in the BIG-IP session table.
Why it's wrong here
The session table is designed for stateful information like session IDs, not for caching large amounts of static content. Using it for caching would quickly exhaust the device's memory, lead to performance degradation, and is not a supported or recommended way to implement HTTP content caching on the BIG-IP platform.
- ✓
Apply a Web Acceleration profile with an enabled cache object.
Why this is correct
The Web Acceleration profile is the native, optimized way to implement HTTP caching on the BIG-IP. It allows administrators to define cache policies based on URI, file type, or HTTP response headers, ensuring that static content is served directly from the BIG-IP’s memory, which is much faster and reduces backend server utilization.
- ✗
Configure the 'HTTP-Compress' profile to shrink the size of responses.
Why it's wrong here
Compression reduces the payload size, which saves bandwidth and decreases download time for clients. However, it does not cache content. The server must still process the request and generate the content, meaning the backend load is not significantly reduced in the same way that caching provides.
