A network administrator is setting up a new device on the network. The device has a MAC address that was assigned by the manufacturer. What is the primary purpose of this MAC address?

To encrypt data sent by the device

To provide a unique identifier for the device on the local network

To determine the device's IP address

To identify the device on the internet

A network engineer is explaining to a trainee how a packet travels from a host on network 10.1.1.0/24 to a host on network 10.2.2.0/24. The trainee asks why the packet's destination MAC address changes at each router hop but the destination IP address does not. Which response is correct?

MAC addresses identify the next-hop device on the local link, while IP addresses identify the final destination end to end

IP addresses are only used within a single subnet, so they are replaced at each router

The destination MAC address is the same as the destination IP address at each hop

MAC addresses are globally unique and used for routing across the internet

A network administrator is troubleshooting why a packet sent from a host in one building cannot reach a server in another building. The administrator checks the packet's destination IP address and confirms it is correct. Which layer of the TCP/IP model is responsible for forwarding this packet across the network based on that IP address?
