CompTIA Network+ (N10-007) — Question 632

A network technician installed a new workstation in an empty office for a new employee. The workstation will not connect to the network resources. The NIC and switch connection LED are both green, and the workstation reports an IP address of 169.254.10.1. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The switchport is on the default VLAN.
• B. The BDPU guard is enabled on the switch.
• C. The DCHP relay is misconfigured.
• D. The switchport is administratively down.

Correct answer: C

Explanation

The workstation is receiving an IP address from the APIPA range (169.254.x.x), indicating that it is not getting an IP address from a DHCP server. This suggests that the DHCP relay is misconfigured, making option C the correct choice. The other options either do not directly relate to the inability to obtain a DHCP address or are not likely causes based on the provided symptoms.
