Free CompTIA Network+ N10-008 Practice Question

The correct answer is 'Faulty network cable'. When a single workstation experiences a 'network cable unplugged' error while others on the same network segment do not, and physical inspection shows that the cable is connected, the issue is likely a faulty cable. Although other options such as 'Network adapter driver issue' and 'Disabled network port' could also result in connectivity problems, they would not normally give the specific 'network cable unplugged' error message. Incorrect VLAN settings would affect network access but wouldn't trigger this physical layer error message. 'Misconfigured DHCP settings' would affect IP address assignment and network access but wouldn't cause a 'network cable unplugged' message. 'Switch port misconfiguration' might be a concern, but since other users on the same network segment are not affected, it is less likely to be isolated to one single port impacting a single user.
