Question
A network administrator must ensure that a printer will still be assigned a specific IP address even if all addresses are depleted. Which of the following network configuration concepts is this describing?
- A. VLAN
- B. Lease
- C. Reservation Correct
- D. Exclusion
Explanation
A DHCP reservation ties a specific IP address to a client (usually by MAC address), so that client always receives the same address and it is never handed to another device, even when the rest of the pool is used up. An exclusion removes addresses from the pool so DHCP never assigns them at all, which would not give the printer that address. A lease is the time-limited assignment of any address, and a VLAN is a layer 2 segmentation method.
