   An administrator has configured cookie persistence on a virtual server. During testing, the administrator notices that the BIG-IP is not inserting a persistence cookie into the HTTP responses. The application does not set any cookies. What is the most likely reason for this behavior?

   • AThe persistence profile is not assigned to the virtual server.
   • BThe cookie persistence profile is set to 'HTTP cookie passive' mode.
   • CThe persistence timeout is set to 0.
   • DThe cookie name is incorrect.

   Which statement best describes how a persistence profile affects the behavior of a virtual server?

   • AIt ensures that all clients are directed to the same pool member regardless of session.
   • BIt changes the load balancing algorithm to round robin for all sessions.
   • CIt disables load balancing entirely and sends all traffic to the first available pool member.
   • DIt overrides the load balancing algorithm for matching sessions, directing them to the same pool member.

   A company runs a web application that uses SSL/TLS for all client connections. The application does not use cookies and clients may connect from varying IP addresses (e.g., mobile users). The administrator wants to maintain session stickiness without relying on client IP addresses. Which persistence profile should be used?

   • ACookie persistence
   • BSource address persistence
   • CSSL session ID persistence
   • DUniversal persistence

   What is the primary purpose of a persistence profile in a BIG-IP load balancing configuration?

   • ATo distribute client requests evenly across all pool members based on current server load.
   • BTo ensure that all requests from a given client session are directed to the same pool member for the duration of the session.
   • CTo monitor the health of pool members and automatically remove unhealthy ones from rotation.
   • DTo encrypt all traffic between the client and the pool members to ensure confidentiality.

   A company runs a web application that uses both HTTP and HTTPS. The HTTP virtual server uses source address persistence, and the HTTPS virtual server uses SSL session ID persistence. Users report that when they switch from HTTP to HTTPS during the same session, they are sometimes sent to a different server. What is the most likely cause?

   • AThe SSL session ID changes when switching from HTTP to HTTPS.
   • BThe load balancing method is different on the two virtual servers.
   • CThe source address persistence profile has a shorter timeout than the SSL session ID profile.
   • DThe two virtual servers use different persistence profiles, so the session is not maintained across protocols.
