Explanation

Disabling all unused ports on the switch is the best solution because it directly prevents a visitor from plugging an unauthorized device into an open switch port to gain network access. Option A (QoS) only manages bandwidth priority and provides no security. Option B (strong usernames/passwords) is good practice but does not stop a visitor from physically connecting to the network. Option D (labeling the room) is a non-technical, unenforceable control that relies on human compliance. Disabling unused physical ports is a direct, technical countermeasure against unauthorized physical network access.
