In which scenario is a full proxy TCP connection required?
The correct answer is C. when compression is enabled. HTTP compression requires the ADC to fully buffer and process the response payload, which is only possible when a full proxy TCP connection is in place to terminate both client and server connections independently.

Why each option
HTTP compression requires the ADC to fully buffer and process the response payload, which is only possible when a full proxy TCP connection is in place to terminate both client and server connections independently.
SIP UDP load balancing operates at Layer 4 and uses connectionless UDP transport; it does not require the ADC to maintain a full TCP proxy state.
DNS load balancing uses UDP/TCP DNS queries that are resolved and forwarded at Layer 4 to 7 without requiring the ADC to transform a persistent TCP payload stream.
Layer 3 load balancing routes packets based on IP addressing without connection state or content inspection, requiring no full proxy TCP termination.
