   A client is unable to reach a virtual server, but the BIG-IP can ping the client's default gateway. The virtual server is configured with a SNAT pool, and the pool members are healthy. Which network connectivity troubleshooting step should the administrator perform to isolate the issue?

   • AExamine the BIG-IP's routing table to confirm the client's subnet is reachable via the correct interface.
   • BCheck the SNAT pool's address list to ensure the addresses are routable back to the client's network.
   • CVerify the client's default gateway is configured to route traffic to the BIG-IP's self IP.
   • DReview the virtual server's destination address and ensure it matches the client's requested URL.

   An administrator notices that the 'Clientside TMM CPU Usage' metric is consistently high. What does this indicate?

   • AThe SSL certificates are expired
   • BThe Traffic Management Microkernel is processing a high volume of client-side traffic
   • CThe pool members are unhealthy
   • DThe management CPU is overloaded

   A company is planning to migrate a large-scale application to a new BIG-IP. The application is expected to handle 50,000 concurrent connections and 1 Gbps of throughput. The administrator is choosing between two BIG-IP models: Model A has 8 TMM cores and 16 GB of memory, while Model B has 16 TMM cores and 32 GB of memory. The administrator also needs to consider SSL termination for all traffic. Which factor is most critical in deciding between the two models?

   • AThe number of TMM cores, because SSL termination is CPU-intensive and more cores will provide better performance.
   • BThe number of VLANs supported, because the application may require multiple network segments.
   • CThe amount of memory, because 50,000 concurrent connections will consume significant memory for connection tables.
   • DThe throughput capacity, because 1 Gbps is the primary constraint and both models can handle it.
