A workstation has a network link light, but it cannot access internal network resources. Which of the following is the MOST likely cause of the issue?
The correct answer is B. IP address conflict. A link light confirms physical layer connectivity (the cable and NIC are working), but it says nothing about logical network configuration. An IP address conflict occurs when two devices share the same IP address, causing both to have intermittent or no network access while the…

Explanation
A link light confirms physical layer connectivity (the cable and NIC are working), but it says nothing about logical network configuration. An IP address conflict occurs when two devices share the same IP address, causing both to have intermittent or no network access while the physical connection remains intact. Slow transfer speeds (A) would still allow access to resources. An incorrect gateway (C) would prevent access to external networks (internet) but would typically still allow access to internal resources on the same subnet. Packet collisions (D) are a Layer 1/2 concern more common in hub-based networks and would not typically block all internal access while the link light remains on.
