An Address Resolution Protocol message is sent to all the computers in a subnet  (broadcast message) to find the data link layer address.Select one:TrueFalse

Assessment of the Statement

1. Understanding Address Resolution Protocol (ARP):

   • ARP is a communication protocol used for mapping an Internet Protocol address (IP address) to a physical machine address (data link layer address) that is recognized in the local network.

2. Functionality of ARP in Subnet:

   • When a device in a subnet wants to communicate with another device and only knows its IP address, it sends an ARP request as a broadcast message to all devices in the subnet. This request seeks to find out which device corresponds to the specified IP address.

3. Nature of ARP Messages:

   • The ARP request is indeed a broadcast message, meaning it is sent to all machines on the local network (subnet) to identify the hardware (MAC) address associated with a given IP address.

Conclusion

The statement is True. An ARP message is indeed sent as a broadcast message to all computers in a subnet to find the corresponding data link layer address.
