The correct answer is B. Two-arm mode. Two-arm mode places the Citrix ADC directly in the network path between the client and server - traffic physically flows through the device on two separate network interfaces (one facing clients, one facing servers), which is why it earns the "inline" label.

Explanation

Two-arm mode places the Citrix ADC directly in the network path between the client and server - traffic physically flows through the device on two separate network interfaces (one facing clients, one facing servers), which is why it earns the "inline" label. One-arm mode (C) is wrong because the ADC sits off to the side on a single interface, with traffic redirected to it rather than passing through it - the opposite of inline. MAC-based forwarding (A) is a Layer 2 traffic-handling technique used within a deployment, not a deployment topology itself. Transparent mode (D) is a configuration mode that makes the ADC invisible to endpoints (no IP change), but it's not the standard term for the physical inline topology.

Memory tip: Think of "two arms" as two arms stretching across a hallway, blocking all traffic that walks through - that's inline. "One arm" only reaches out to grab traffic when needed, so nothing passes through it.
