Which filter uses a list of Finance Department Computers to control leases?

• A. MAC Address Filter
• B. Option Filter
• C. NAC Filter
• D. Fingerprint Filter

Answer: (A)

The main idea is using device identity to control which DHCP leases are issued. A MAC address filter does exactly that by maintaining a list of allowed Finance Department computers’ MAC addresses. When a device requests a lease, the DHCP server checks the device’s MAC against this list and issues a lease only if there’s a match. This makes the filter perfect for enforcing a whitelist of authorized machines for leasing.

Option-based filtering would focus on DHCP options rather than device identity, so it wouldn’t directly enforce a list of specific computers. NAC filtering relates to broader network access control rather than DHCP lease enforcement, and fingerprint filtering relies on device fingerprints rather than a simple, explicit list of known machines.
