What does 'Persistence: NONE' indicate for a vServer in the diagnostic output?

• A. No persistence is applied.
• B. Session persistence is based on source IP
• C. Cookie-based persistence is used
• D. URL-based persistence is used

Answer: (A)

Persistence NONE means there is no session persistence configured on this vServer. In practice, the ADC will not remember or tie a client to a specific backend server across requests. Each new request can be routed to any eligible Real Server according to the load-balancing method, so the same user could be served by different servers in different requests. If you need session continuity, you’d configure a persistence method (such as source IP-based or cookie-based persistence).
