   A BIG-IP administrator is troubleshooting a performance issue where clients are experiencing timeouts. The administrator runs tcpdump on the BIG-IP's client-facing interface and sees that the client's SYN packets are arriving, but the BIG-IP is not sending SYN-ACKs. The administrator also checks the BIG-IP's statistics and sees that the 'Client Packets Dropped' counter is increasing, and the 'Current Connections' statistic is at its maximum limit. What is the most likely cause of the timeouts?

   • AThe client is sending malformed SYN packets that are being rejected.
   • BThe server is not responding to the BIG-IP's connection requests.
   • CThe connection table is full, so the BIG-IP is dropping the SYN packets before it can process them.
   • DThe BIG-IP is dropping the SYN packets due to network congestion on the client-facing interface.
