You answer would have been right if HTTP optimization were to be required but it is not required. That's why C is the most appropriate way to answer the question.
Selected Answers: C
HTTP application
Hardware acceleration for performance
HTTP optimization features are NOT required
This points directly to a Layer 4–only solution.
Why Performance (Layer 4) with fastL4 is correct
fastL4:
Uses hardware acceleration (ePVA / Fast Path) when available
Provides very high throughput and low latency
Does not inspect or optimize HTTP (no Layer 7 features)
Performance (Layer 4) virtual servers are specifically designed for this use case.
Selected Answers: C
The Performance (Layer 4) virtual server type uses the fastL4 profile, which leverages hardware acceleration (PVA - Packet Velocity ASIC) for high-performance throughput. Since HTTP optimization features are explicitly not required, there's no need for a Standard or Performance (HTTP) virtual server, which would add HTTP profile overhead. The fastL4 profile bypasses full proxy processing and passes traffic at the hardware level, perfectly matching the requirement for hardware acceleration without HTTP optimization.
An organization needs to deploy an HTTP application on a BIG-IP system. The requirements specify hardware acceleration to enhance performance, while HTTP optimization features are not required. What type of virtual server and associated protocol profile should be used to meet these requirements? (Choose one answer)
