Which NetScaler feature allows blocking client drives if the client device fails a security scan without changing XenDesktop configuration?

• A. Traffic Policy
• B. SmartAccess
• C. SmartControl
• D. Authorization Policy

Answer: (C)

SmartControl is the NetScaler feature that enforces the posture and capabilities of the client device at the gateway. It can block access to client drives if the device fails a security scan, and it does this without requiring any changes to XenDesktop configuration. This posture-based restriction operates at the gateway layer, so you can enforce security before a session is launched, keeping XenDesktop policies intact. Other options address traffic handling, general access decisions, or authorization, but they don’t provide the specific gateway-level control to block client drive redirection based on a security posture.
