A small office with many transient visitor devices is experiencing IP-pool exhaustion. The network administrator decides that each dynamically assigned IP address should be reclaimed more quickly so that it can be handed out to new clients sooner. Within the DHCP scope configuration, which specific parameter must the administrator adjust to shorten the length of time a client can keep an address before it must attempt to renew?
The correct parameter is "Lease Time" (sometimes called Lease Duration). It defines the period for which an IP address is valid before the client must renegotiate the lease. Reducing this value causes addresses to return to the pool sooner in high-turnover environments. Changing the Range only alters how many addresses are available, a Reservation permanently ties an address to a given MAC address, and Scope Options carry ancillary settings such as DNS or gateway information but do not affect lease duration.
