• Question 185:

  Refer to the exhibit

  

  The network team creates a new VLAN on the switches. The BIG-IP Administrator needs to create a configuration on the BIG-IP device. The BIG-IP Administrator creates a new VLAN and Self IP, but the servers on the new VLAN are NOT reachable from the BIG-IP device.

  Which statement is true concerning SSL termination?

  A. A virtual server that has both ClientSSL and ServerSSL profiles can still support cookie persistence.

  B. Decrypting traffic at the BIG-IP allows the use of iRules for traffic management, but increases the load on the pool member.

  C. When any virtual server uses a ClientSSL profile, all SSL traffic sent to the BIG-IP is decrypted before it is forwarded to servers.

  D. If a virtual server has both a ClientSSL and ServerSSL profile, the pool members have less SSL processing than if the virtual server had only a ClientSSL profile.

  Correct Answer: A

If a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets?

  A. The source address would not change, but the destination address would be translated to the origin address.

  B. The destination address would not change, but the source address would be translated to the origin address.

  C. The source address would not change, but the destination address would be translated to the NAT's address.
