Question 13

What information does the forwarding table require so that the device forwards traffic? (Choose three.)

    Correct Answer: B, C, E

    The forwarding table requires the next hop IP address to determine the next point for sending the packet. It also needs the outgoing interface name to specify which interface to use for sending the packet out. Lastly, it requires the next hop MAC address to ensure the packet is delivered to the correct device on the next hop within the local network. Values such as the BGP local preference and OSPF metric are used for routing decisions but are not directly included in the forwarding table.

Discussion
thatstrawOptions: BCE

The forwarding table requires the following three pieces of information so that the device can forward traffic: B. next hop IP address - The next hop IP address is used to determine the next point to which the packet should be sent on its way to the final destination. C. outgoing interface name - The outgoing interface name indicates which physical or logical interface the packet should be sent out of. E. next hop MAC address - The next hop MAC address is needed for Layer 2 forwarding within the local network, ensuring the packet is delivered to the correct device on the next hop. Explanation of Other Options: - A. BGP local preference value: This value is used in BGP routing decisions to select the best path but is not used in the forwarding table for actual packet forwarding. - D. OSPF metric value: The OSPF metric is used to calculate the best path within the OSPF routing protocol but is not directly included in the forwarding table.
