A Citrix ADC receives packets destined for a MAC address owned by the ADC, but the destination IP does not belong to the ADC. Layer 3 Mode is enabled by default. What will the ADC do with the packets?

A Citrix ADC receives packets destined for a MAC address owned by the ADC, but the destination IP does not belong to the ADC. Layer 3 Mode is enabled by default. What will the ADC do with the packets?

• A. Route the packets.
• B. Bridge the packets.
• C. Drop the packets.
• D. Process the packets.

Answer: (A)

Layer 3 mode makes the Citrix ADC act like a router. When a frame arrives with the ADC’s MAC as the destination but the IP destination isn’t one of the ADC’s own IPs, the device doesn’t try to process it as local traffic. Instead, it looks up the destination IP in its routing table and forwards the packet out the appropriate interface toward the next hop. In other words, it will route the packet to its destination network rather than bridging the frame or dropping it, assuming a route exists. If there’s no route, it would rely on a default route or drop, but with a valid route it forwards them.
