Host B receives an ARP request frame that includes the IP address of Host A. What will Host B do with that information?

Host B receives an ARP request frame that includes the IP address of Host A. What will Host B do with that information? ( Choose Two)

• Record the IP address and MAC address of Host A in its own ARP cache
• Send an ARP reply as a unicast back to Host A
• Send out an ARP request as a broadcast to the destination address ff:ff:ff:ff:ff:ff
• Associate the IP address with a port and a VLAN

Explanation

The correct actions that Host B will take with the information in the ARP request frame are:

“Record the IP address and MAC address of Host A in its own ARP cache.”

When Host B receives an ARP request frame that includes the IP address of Host A, it will record the IP address and MAC address of Host A in its own ARP cache. This will allow Host B to quickly look up the MAC address of Host A in the future when it needs to send data to Host A.

“Send an ARP reply as a unicast back to Host A.”

In response to the ARP request, Host B will also send an ARP reply as a unicast back to Host A. This reply will include the IP and MAC address of Host B, and it will allow Host A to update its own ARP cache with the necessary information.

Host B will not send out an ARP request as a broadcast or associate the IP address with a port and VLAN. These actions are not part of the ARP process.
