Selected Answer: D the answer is D

Selected Answer: D The media encryption mode options are: • Force encrypted: All media to and from the zone/subzone has to be encrypted. If the target system/endpoint is set to not use encryption, then the call will be dropped. • Force unencrypted: All media has to be unencrypted. If the target system/endpoint is set to use encryption, then the call may be dropped; if it is set to use Best effort then the call will fall back to unencrypted media. • Best effort: Use encryption if it is available, otherwise fall back to unencrypted media. • Auto: No specific media encryption policy is applied by the Expressway. Media encryption depends entirely on the target system/endpoint requests. This is the default behavior and is the same as how the Expressway worked before this feature was introduced. Encryption policy (any encryption setting other than Auto) is applied to a call by routing it through a back-to-back user agent (B2BUA) hosted on the Expressway.

Should be D
