An LTM device is used to load balance web content over a secure channel.
The developers of the web content have done a trace using an HTTP profiler application. They believe that allowing the LTM device to compress traffic to the client will improve performance. The client can utilize GZIP or deflate compression algorithms.
An LTM Specialist must implement the compression.
The LTM Specialist has completed the following actions:
1. Create the relevant profile.
2. Apply the relevant profile to the virtual server (VS).
After applying the relevant profile, the LTM device is failing to compress the traffic. Instead, the traffic is being served with an error.
What is the problem?
- A. The Protocol Profile (Server) option of "Allow Compression" needs to be enabled.
- B. The incorrect compression algorithm is applied to the compression profile.
- C. The Protocol Profile (Client) option of "Allow Compression" needs to be enabled.
- D. The LTM device CANNOT SSL offload the traffic in order to read and compress it.

解説:
Explanation
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.
