USIP mode stands for what?

• A. Use Source IP
• B. Use Server IP
• C. Use Subnet IP
• D. Use System IP

Answer: (A)

USIP mode means using the original client IP as the source IP when the appliance forwards traffic to the backend servers. In this mode, the servers see the client’s IP address as the source rather than the Citrix ADC’s own IP, which is important for accurate logging, client-based policies, and proper return routing. This is why the correct interpretation is “Use Source IP.”

The other options don’t fit because they don’t describe preserving or using the client’s IP in the backend connections. They would imply using the server’s IP, a subnet IP, or the system’s own IP, which contradicts the actual behavior of USIP mode.
