Which topology is commonly referred to as an inline ADC?

• A. Two-arm mode
• B. MAC-based forwarding
• C. Use Source IP
• D. One Arm Mode

Answer: (A)

Inline ADC deployments place the appliance directly in the data path between clients and servers, so every packet passes through it for inspection and processing. The typical way to realize this is a two-arm topology, with one network connection toward the client side and another toward the server side. That physical arrangement makes the ADC literally inline, enabling features like SSL offload, WAF, and real-time traffic manipulation as traffic moves from one side to the other.

In contrast, one-arm mode uses a single interface and relies on routing or virtual IP redirection to send traffic to the ADC, which is not truly in the direct path of all traffic. The other terms describe switching or routing behaviors, not the actual inline deployment topology, so they don’t define how an inline ADC is usually implemented.
