What is the purpose of a MAC address on a network device?

Answer options

• A. unique network address that identifies the network interface of a device
• B. unique network interlace address that is provided by the DHCP server
• C. unique hardware address that identifies the network interface of a device
• D. unique hardware interface address that is provided by the central switch

Correct answer: C

Explanation

The correct answer, C, describes the MAC address accurately as a unique hardware address essential for identifying the network interface of a device. Option A is incorrect because it refers to a network address rather than a hardware address. Option B mistakenly states that the MAC address is provided by the DHCP server, which is not true, as DHCP deals with IP addresses. Option D incorrectly attributes the MAC address provision to a central switch.
