Which mode must be configured on NetScaler to forward any packets that are not destined for an IP address configured on the appliance?

• A. Layer 3 Mode
• B. USIP
• C. Layer 2 Mode
• D. MBF

Answer: (A)

To forward packets that aren’t destined for an IP configured on the appliance, the device needs to perform IP routing. Layer 3 Mode makes the NetScaler act as a router, with an IP routing stack and a routing table that directs such traffic toward its destination, even when the destination IP isn’t one of the appliance’s own IPs. Layer 2 Mode, by contrast, operates as a bridge/switch within the same LAN and does not route traffic between subnets, so non-local IP packets wouldn’t be forwarded beyond the appliance. USIP and MBF are specialized features or modes that don’t provide the general routing behavior required here. So the correct mode is Layer 3 Mode.
