The duration for which a DHCP server loans an IP address to a DHCP client is a DHCP _______.

• A. Scope
• B. Lease
• C. TTL
• D. Address

Answer: (B)

In DHCP, the duration you’re talking about is the lease. A lease is the temporary permission for a device to use a specific IP address. The DHCP server assigns an IP along with a lease time, and the client must renew that lease before it expires. If the lease isn’t renewed, the address goes back into the pool to be reassigned to someone else. This mechanism helps manage available addresses and prevent conflicts. The other terms don’t fit this idea: a scope is the pool of addresses the server can hand out, not how long an address is valid. TTL refers to time-to-live for packets, not DHCP address assignments. Address is just the IP itself, not the duration of its use.
