• Question 220:

  Refer to the exhibit.

  

  A BIG-IP Administrator creates a new Virtual Server. The end user is unable to access the page. During troubleshooting, the administrator learns that the connection between the BIG-IP system and server is NOT set up correctly. What should the administrator do to solve this issue?

  A. Disable Address Translation

  B. Set Address Translation to Auto Map, configure a SNAT pool, and have pool members in the same subnet of the servers

  C. Set Address Translation to SNAT and configure a specific translation address

  D. Set Address Translation to SNAT and have self-IP configured in the same subnet of servers

  Correct Answer: C

  The status of the pool can be seen that the members are all up, indicating that the network from F5 to the server is no problem, so there is no need to configure selfip on the same subnet. The monitor is normal but the access is not normal, you have to consider the problem of snat, you can configure automap or configure snat and specify snat ip.
