If a packet is addressed to a MAC owned by the ADC, but the destination IP doesn't belong to the ADC and Layer 3 is enabled by default, what will the ADC do with the packet?

If a packet is addressed to a MAC owned by the ADC, but the destination IP doesn't belong to the ADC and Layer 3 is enabled by default, what will the ADC do with the packet?

• A. bridge
• B. drop
• C. route
• D. process

Answer: (C)

When a frame arrives with a destination MAC that belongs to the ADC, the device will accept the frame. If Layer 3 is enabled, it doesn’t just forward at Layer 2; it also looks at the IP header to decide where to send the packet next. Since the destination IP isn’t local to the ADC, it will use its routing table to forward the packet to the appropriate next hop (i.e., it routes the packet).
