Which statement best describes a Two-Arm deployment of a Citrix ADC?

• A. All traffic flows through a single interface
• B. It uses two separate networks, typically DMZ and internal
• C. It requires a Forward Proxy
• D. It operates in Transparent mode

Answer: (B)

Two-arm deployment is about placing the ADC on two separate networks, typically a DMZ-facing network and an internal network. With interfaces on both sides, the appliance receives external client requests from the DMZ, performs its load balancing, security, or offloading tasks, and routes traffic onward to internal servers. Responses travel back through the same networks, providing perimeter separation and centralized policy enforcement at the network edge. This contrasts with a one-arm setup where all traffic passes through a single interface, the use of a forward proxy (which is a different mechanism), or Bridge/Transparent mode where the ADC acts more like a pass-through device rather than a dedicated gateway between two distinct networks.
