1. Refer to the exhibit. True or False? R1 must encapsulate received packets into new frames before forwarding them to R2.
- True
- False
Explanation: The correct answer is True. Because R2 is on a different L2 segment than PC1, R1 must de-encapsulate received packets from PC1 and re-encapsulate them in a new L2 frame to forward to R2.
2. Refer to the exhibit. True or False? R2 will forward frames to R3 with an all 1s Layer 2 address.
- True
- False
Explanation: The correct answer is True. The point-to-point link between R2 and R3 uses the destination address of all 1s.
3. Refer to the exhibit. What action will R3 take to forward a frame if it does not have an entry in the ARP table to resolve a destination MAC address?
- sends a DNS request
- drops the frame
- sends an ARP request
- sends frame to the default gateway
Explanation: R3 will send an ARP request to resolve the Layer 2 address of the destination host.
