Citrix CCA-AppDS 1Y0-241 Question # 3 Topic 1 Discussion

Compression is a feature that reduces the size of the data that is exchanged between the Citrix ADC appliance and the clients or servers. Compression can be performed by either the appliance or the servers, depending on the configuration and the availability of the compression feature on both ends. If the servers have the compression feature installed, they can automatically compress the responses before sending them to the appliance, regardless of the ‘Accept Encoding’ header in the requests. This can cause a problem if the appliance is also configured to remove the ‘Accept Encoding’ header from all requests, as it will prevent the appliance from detecting that the responses are already compressed and applying its own compression policy. Therefore, the correct answer is B. The servers are automatically compressing all responses.
