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.
