CompTIA Network+ (N10-008) — Question 610

A technician is working on a ticket for a user in the human resources department who received a new PC that does not connect to the internet. All users in human resources can access the internet. The technician can ping the PC from the human resources router but not from the IT network. Which of the following is the most likely cause of the issue?

Answer options

• A. Duplicate IP address
• B. Misconfigured RIP
• C. Improper VLAN assignment
• D. Incorrect default gateway

Correct answer: D

Explanation

The correct answer is D, as an incorrect default gateway would prevent the PC from routing traffic to the internet, despite being reachable on the local network. A duplicate IP address (A) might cause conflicts but would not explain why the PC can be pinged from one network and not another. Misconfigured RIP (B) and improper VLAN assignment (C) are less likely causes since they would affect broader connectivity issues rather than just the ability to reach the internet.
