Resolve DHCP Issues in Corporate Office Building
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?

A. B. C. D.D.
The issue described in this scenario is that the DHCP service is running low on available IP addresses to assign to visiting laptops, resulting in some users being unable to access the network. The building has its own class C subnet with 250 addresses available in the DHCP scope.
To address this issue in the long term, we need to find a solution that will ensure that there are enough IP addresses available to meet the needs of the visiting users. Let's review the options provided:
A. Manually delete address leases from DHCP. This option does not address the root cause of the issue, which is the limited number of available IP addresses in the DHCP scope. It may provide a temporary solution, but it is not a long term solution.
B. Create reservations in DHCP for users frequently visiting this location. Creating reservations in DHCP for frequent visitors may be helpful in ensuring that these users have a consistent IP address assigned to them each time they visit. However, it does not address the underlying issue of the limited number of available IP addresses. Additionally, it is not feasible to create reservations for every user who visits the location, as there may be many unique visitors each day.
C. Assign static IP addresses to visiting laptops. Assigning static IP addresses to visiting laptops would ensure that each device has a unique IP address and would address the issue of limited IP addresses in the DHCP scope. However, this solution can be difficult to manage and maintain, particularly if there are many unique visitors each day. It can also increase the risk of IP address conflicts if multiple devices are assigned the same static IP address.
D. Reduce the lease duration in the DHCP scope options to one day. Reducing the lease duration in the DHCP scope options can help to ensure that IP addresses are released back into the available pool more quickly, allowing for more frequent turnover of addresses and potentially increasing the number of available addresses overall. This solution would require monitoring and management to ensure that lease durations are set appropriately and that IP addresses are being released in a timely manner.
In conclusion, the best long term solution to this issue is likely to be D. Reducing the lease duration in the DHCP scope options to one day. This solution addresses the root cause of the issue by allowing for more frequent turnover of IP addresses, potentially increasing the number of available addresses overall. However, it would require monitoring and management to ensure that lease durations are set appropriately and that IP addresses are being released in a timely manner.
