Question
A company has a corporate office building that is used by 50 to 100 unique visitors each day for meetings. Users routinely report that they are unable to access the network with their laptops when visiting this location. The help desk reports that these users are not getting IP addresses automatically assigned. After an investigation, the server administrator has determined that the DHCP service is functioning, but a minimal number of addresses are available for lease. The building is on its own class C subnet and has 250 addresses in the scope. Which of the following represents a long term solution tothe problem?
Options
- AManually delete address leases from DHCP.
- BCreate reservations in DHCP for users frequently visiting this location.
- CAssign static IP addresses to visiting laptops.
- DReduce the lease duration in the DHCP scope options to one day.

Why each option
To address DHCP address exhaustion for transient visitors, reducing the DHCP lease duration allows IP addresses to be released back into the pool more quickly.
Manually deleting address leases is a reactive, labor-intensive, and temporary workaround, not a sustainable long-term solution to prevent recurring scope exhaustion.
Creating DHCP reservations is designed for specific devices needing a consistent IP and is impractical and unmanageable for 50-100 unique, transient visitors daily.
Assigning static IP addresses to visiting laptops is highly unscalable and cumbersome for a large number of temporary users, requiring manual configuration on each device.
Reducing the DHCP lease duration in the scope options to one day ensures that IP addresses are released back into the available pool more quickly after visitors leave. This action prevents the DHCP scope from becoming exhausted due to lingering leases from transient users, making addresses available for the next set of daily visitors.
