   A BIG-IP is configured to send health checks to a backend server. The health check is initiated by the BIG-IP itself. What source IP will the backend server see for these health check connections?

   • AThe client's original source IP, if SNAT is disabled.
   • BThe self-IP of the BIG-IP on the egress VLAN.
   • CThe management IP address of the BIG-IP.
   • DA random IP from a SNAT pool, if one is configured.

   When SNAT automap is configured on a virtual server, how does the BIG-IP select the egress source IP address for a connection?

   • AIt randomly selects any IP address from the BIG-IP's routing table
   • BIt always uses the management IP address of the BIG-IP
   • CIt uses the IP address of the pool member that will receive the traffic
   • DIt uses the self-IP address of the BIG-IP that is on the same subnet as the destination

   A BIG-IP has self-IPs 192.168.1.1 on VLAN1 and 192.168.2.1 on VLAN2. A virtual server on VLAN1 has SNAT Automap enabled. The backend server is on VLAN2. What source IP will the backend server see?

   • A192.168.2.1, the self-IP on the egress VLAN to the backend.
   • B192.168.1.1, the self-IP on the virtual server's VLAN.
   • CA random IP from a SNAT pool, if one is configured.
   • DThe client's original IP, because Automap does not translate.

   A SNAT pool contains IPs 10.10.10.10 and 10.10.10.11. A client with IP 203.0.113.5 connects to a virtual server that uses this SNAT pool. The BIG-IP hashes the client IP and selects 10.10.10.10. The client opens a second connection. What source IP will the backend see for the second connection?

   • A10.10.10.10, because the hash of the client IP is consistent.
   • B10.10.10.11, because the BIG-IP uses round-robin for new connections.
   • C203.0.113.5, the client's original IP.
   • DA random IP from the pool, because the BIG-IP selects randomly.

   • AThe self-IP of the BIG-IP on the egress VLAN.
   • BThe destination IP of the virtual server.
   • CThe client's original source IP.
   • DAn IP from a SNAT pool, if one is configured.
