A technician is called into an office where multiple users are reporting duplicate IP address errors. Upon arrival, the technician skims notes from the previous technician who serviced the office…

Question

Options

• AThe previous technician turned off DHCP to free up resources for QoS functionality.
• BThe previous technician decided to use DNS instead of DHCP for handling IP addresses.
• CThe previous technician moved the office to a mismanaged static IP address setup.
• DThe previous technician did not setup DHCP reservations properly and therefore the router is giving multiple users

• A

Explanation

When DHCP is disabled, devices no longer automatically receive unique IP addresses from a central server. Instead, each device must be manually assigned a static IP address. If the previous technician switched to static IPs but did not carefully manage which addresses were assigned to which devices (or documented the assignments poorly), it is very easy for two devices to end up configured with the same IP address, resulting in the 'duplicate IP address' conflict errors users are seeing. Freeing resources for QoS (A) is not a valid reason to disable DHCP, and QoS does not require DHCP to be off. DNS (B) handles name resolution, not IP address assignment - it is not a replacement for DHCP. DHCP reservations (D) are a feature within DHCP itself; if DHCP were still running, this could be a cause, but DHCP is confirmed disabled, making static IP mismanagement the correct answer.
