Apple Certified Support Professional (ACSP) Practice Exam

Question: 1 / 400

Which of the following addresses a device within a local network?

Subnet Mask

Router Address

MAC Address

The MAC address is a unique identifier assigned to network interfaces for communications at the data link layer of a network. It specifically addresses a device within a local network, allowing devices to identify and communicate with each other on the same local area network (LAN). Each network interface controller (NIC) has a MAC address that is used to route data packets between devices in the same network segment.

The subnet mask is used to divide the IP address into its network and host components but does not uniquely identify a device. The router address refers to the address of a device that routes traffic between different networks, and the global address typically refers to an externally-facing public IP address used for internet routing. While all these other options play crucial roles in networking, they do not specifically address a device within a local network like the MAC address does.
