   A virtual server has a persistence profile that uses source address persistence. A client is sending all traffic from the same source IP. What will happen?

   • ARequests will be sent to the pool member with the fewest connections.
   • BRequests will be dropped because persistence is not configured correctly.
   • CAll requests from that client will be sent to the same pool member.
   • DRequests will be load balanced evenly across all pool members.

   A pool member is marked up, but the application is actually down. The monitor is an ICMP monitor. What is the most likely reason the monitor reports the member as up?

   • AThe ICMP monitor only checks if the host is reachable, not if the application is running.
   • BThe monitor's timeout is set too high, causing it to mark the member up before the application fails.
   • CThe monitor's interval is set too low, causing it to miss the application failure.
   • DThe monitor is associated with the wrong pool member.

   A pool has two members with the same IP address but different ports: 10.1.1.10:80 and 10.1.1.10:8080. The pool is associated with an HTTP monitor that checks port 80. The member on port 8080 is marked down even though the service on that port is healthy. What is the most likely cause?

   • AThe monitor is not associated with the pool, so it defaults to marking members down.
   • BThe pool member on 8080 is not configured with a health monitor.
   • CThe monitor is checking the wrong port for the member on 8080.
   • DThe load balancing method is causing the member on 8080 to be marked down.

   A pool member is marked down, but the application is responding to TCP connections on the correct port. The pool has an HTTP monitor associated, but the monitor's send string is 'GET /' and the receive string is '200 OK'. The application returns a 404 for '/'. What is the most likely issue?

   • AThe monitor's receive string does not match the application's response, causing a false down.
   • BThe monitor's interval is too short, causing the BIG-IP to mark the member down between checks.
   • CThe monitor's timeout is too long, causing the BIG-IP to wait too long and mark the member down.
   • DThe monitor is not associated with the pool member, so it is not being checked.
