Q: A network interface’s manufacturer has to be known. Where are you going to search for this data?

• The last octet of a Media Access Control (MAC) address
• The first three octets of a Media Access Control (MAC) address
• The first octet of a Media Access Control (MAC) address
• The fourth octet of a Media Access Control (MAC) address

Explanation: If you look at the MAC address, also known as the Media Access Control address, of a network interface, you will be able to determine who the manufacturer of the network interface is. The first few digits of a MAC address often identify the manufacturer of the device. The Media Access Control (MAC) address is a unique identification that is issued to network interfaces.

This component of the MAC address is referred to as the Organizationally Unique Identifier (OUI), and it is responsible for determining the manufacturer. You can seek OUI information in databases that are open to the public and are made accessible by organizations such as the IEEE (Institute of Electrical and Electronics Engineers). You can discover the manufacturer associated with a MAC address by using search tools or databases that look up MAC addresses online and enable you to enter the OUI.
