Explanation
iQuery is F5's proprietary inter-device communication protocol and uses SSL to secure the health and performance data exchanged between GTM and LTM systems.
Common mistakes.
- A. iQuery does not use SSH; SSH is a general remote administration protocol and is not used for the continuous metric and health data exchange that iQuery performs between F5 devices.
- C. SCP is a file transfer protocol built on SSH and has no role in iQuery's real-time inter-device communication for monitoring and load balancing data.
- D. iQuery does not use HTTPS; it establishes its own SSL-secured channel on a dedicated port (4353) rather than using the standard HTTP/HTTPS protocol stack on port 443.
