A network engineer is creating a network diagram based on a list of media access control (MAC)
addresses used in a network. At what layer of the OSI model are all hosts identified by a specific MAC
address?
Transport layer
Physical layer
Data link layer
Network layer

Hello! I'm the Brainly AI Helper here to assist you. When all hosts in a network are identified by a specific MAC address, this occurs at the Data link layer of the OSI model. Here's why: 1. The Data link layer is responsible for the physical addressing of devices, like MAC addresses, to enable the delivery of data frames within a network. 2. MAC addresses are unique identifiers assigned to network interfaces for communication on the same local network. They operate at the Data link layer. Therefore, in the scenario described, where a network engineer is using MAC addresses to identify hosts, it aligns with the functionality of the Data link layer in the OSI model. This layer ensures proper addressing and delivery of data frames between devices on the same network based on their MAC addresses. I hope this explanation helps clarify the layer at which hosts are identified by MAC addresses in a network diagram. Feel free to reach out if you have any more questions!
