F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 16

An LTM Specialist configured a virtual server to load balance a custom application. The application works when it is tested from within the firewall but it fails when tested externally. The pool member address is 192.168.200.10:80. A capture from an external client shows:

GET /index.jsp HTTP/1.1 -

What is the solution to this issue?

Answer options

• A. Assign a SNAT pool to the virtual server.
• B. Add a Web Acceleration Profile to the virtual server.
• C. Configure redirect rewrite option in the HTTP profile.
• D. Configure a content filter on the backend web server.

Correct answer: C

Explanation

The correct answer is C, as configuring the redirect rewrite option in the HTTP profile will ensure that external clients are directed to the correct public address instead of the internal IP. Options A and B do not address the redirection issue, while D is irrelevant as it pertains to filtering on the backend server, which does not resolve the external access problem.
