Citrix Administrator needs to deploy a Citrix ADC between the servers and the client, with servers only allowed to reach the client through the Citrix ADC. In which mode should the administrator deploy the Citrix ADC?

• A. Direct server return
• B. Transparent
• C. Inline
• D. One-arm

Answer: (B)

When you need the device to sit between the two networks and control all traffic that flows between clients and servers, you want it to act as a transparent bridge. That’s exactly what Transparent mode does: the ADC is placed in the data path between the client and the servers without requiring changes to IP addresses or gateway configurations, and it forwards traffic in both directions. The servers reach the client only through the ADC, allowing the ADC to apply load balancing, policies, and other features to all traffic.

Direct Server Return would let server responses bypass the ADC, which defeats the requirement. Inline mode also puts the ADC in the path, but Transparent mode is specifically designed to insert the device between existing network segments without altering endpoint addressing, ensuring all server-to-client traffic passes through the ADC.
