Answers
D.
Incorrect subnet mask
Suggested answer: B

Explanation:

A duplicate IP address occurs when two devices on the same network have the same IP address assigned to them. This can cause intermittent connection issues, as the network devices may not be able to distinguish between the two conflicting devices. A duplicate IP address can be caused by a visitor manually configuring a static IP address that is already in use by another device on the guest network. The network IP range of 192.168.1.0/28 has only 14 usable host addresses, so the chances of a duplicate IP address are higher than a larger network.
