   A virtual server is load balancing traffic to a pool of servers. The servers have a default gateway that points to the BIG-IP. What is the purpose of SNAT in this scenario?

   • ATo allow the servers to route traffic to the internet.
   • BTo ensure return traffic goes through the BIG-IP.
   • CTo hide the client's IP address from the servers.
   • DTo load balance traffic evenly across servers.

   A virtual server has a pool with two members. Both members are down. The 'Action on Service Down' is set to 'Drop'. Users report that connections to the virtual server hang and eventually time out. What is the expected behavior, and what change would make the failure more apparent to users?

   • AThe BIG-IP sends a TCP RST, causing resets; change the action to 'Drop' to make connections time out.
   • BThe BIG-IP rejects the connections, causing resets; change the action to 'Drop' to make connections time out.
   • CThe BIG-IP drops the packets, causing timeouts; change the action to 'Reject' to send TCP resets.
   • DThe BIG-IP ignores the connections, causing timeouts; change the action to 'Reject' to send resets.

   A pool member is marked down even though the application is healthy. The health monitor is an HTTP monitor with a send string of "GET /health" and a receive string of "OK". The application returns "OK" in the response body. Which misconfiguration is most likely causing the false down status?

   • AThe monitor interval is set to 5 seconds, which is too short for the application to respond.
   • BThe receive string is case-sensitive and the application returns "ok" in lowercase.
   • CThe monitor type is HTTP but the application only supports HTTPS.
   • DThe monitor timeout is set to 16 seconds, which is longer than the interval.

   A virtual server uses a source address persistence profile with a default timeout of 5 minutes. The load balancing method is 'Least Connections'. A user reports that after the first connection, all subsequent connections from their workstation go to the same pool member, even though other members have fewer connections. What is the likely cause?

   • AThe persistence timeout is set too low, causing connections to stick to one member.
   • BThe pool member that receives the traffic is the only one that is up.
   • CThe load balancing method is misconfigured and should be 'Round Robin'.
   • DThe persistence profile is overriding the load balancing method for connections from the same source IP.
