Scenario: A Citrix Administrator manages an environment that has an externally accessible website. The administrator would like to provide end-to-end encryption, and use features such as caching and compression on the Citrix ADC.
Which setting should the administrator configure to meet this requirement?
To achieve end-to-end encryption along with caching and compression on a Citrix ADC for an externally accessible website, the correct setting is to configure both the front-end and the back-end to use SSL. This ensures that the data remains encrypted from the user to the Citrix ADC and from the Citrix ADC to the web server, maintaining encryption throughout the whole transmission path. Additionally, SSL protocol supports the necessary optimizations like caching and compression that meet the administrator's requirements.
Compression can only be configured for HTTP and SSL protocols: https://jgspiers.com/netscaler-compression/
https://docs.citrix.com/en-us/citrix-adc/current-release/ssl/how-to-articles/other-tcp-protocols.html
This is the only option that would provide end to end encryption and allow optimizations. Apparently SSL offloading, aka SSL-TCP does not allow optimizations.
In the text for me the "website" involves HTTP/S protocols so it is 'C'.
