Which NetScaler deployment is commonly described as 'inline mode'?

• A. One-Arm Mode
• B. MAC-based Forwarding
• C. Two-Arm Mode
• D. Use Source IP(USIP)

Answer: (C)

Inline mode means the appliance sits directly in the path of traffic between clients and servers, so every packet flows through it for inspection and processing. The two-arm deployment fits this description best because it uses two separate networks: a front-end network for clients and a back-end network for servers. With two distinct interfaces connected to those networks, the NetScaler sits in the data path, allowing it to intercept requests from clients, apply load balancing or SSL offload, and return responses as traffic moves back to the clients. That direct placement in the traffic flow is what people refer to as inline mode. The other options describe different concepts. One-Arm uses a single network interface and isn’t the classic inline path between clients and servers. MAC-based Forwarding is a forwarding method at the MAC layer, not a deployment mode described as inline. Use Source IP is about preserving the original client IP on back-end connections, not about where the appliance sits in the traffic path.
