The LTM Specialist notices the OneConnect feature is working incorrectly.
Why is OneConnect functioning incorrectly?

Answer options

• A. Client must support HTTP/1.0.
• B. Client must support HTTP keep-alive.
• C. Server must support HTTP/0.9.
• D. Server must support HTTP keep-alive.

Correct answer: D

Explanation

The correct answer is D because OneConnect requires the server to maintain persistent connections using HTTP keep-alive. If the server does not support this, it cannot handle multiple requests from the same client efficiently. Options A, B, and C do not address the server's capabilities, which are crucial for OneConnect to function correctly.
