A Citrix Administrator needs to deploy a Citrix ADC appliance to the network through a single VLAN using a single subnet when clients and servers reside on the same subnet. How can the administrator…

Explanation

One-arm mode is correct because it allows the Citrix ADC to connect to the network via a single interface on a single VLAN, making it ideal when clients and servers share the same subnet - the ADC intercepts, processes, and returns traffic through that same interface without requiring network segmentation.

Two-arm (C) is wrong because it requires two separate interfaces typically connecting different VLANs or subnets (client-side and server-side), which contradicts the single-VLAN, single-subnet constraint here.

L2 mode (B) is a behavioral/forwarding mode that makes the ADC act as a transparent bridge - it doesn't describe a physical deployment topology and would not solve the single-VLAN placement requirement on its own.

MAC-based forwarding (D) is a technique used to handle asymmetric routing (when return traffic might bypass the ADC), not a deployment topology - it's a workaround for routing issues, not a solution for single-subnet placement.

Memory tip: Think "one arm, one VLAN" - if the whole environment lives on a single network segment, the ADC only needs one arm reaching into it. Two-arm = two segments; one-arm = one.
