CompTIA Network+ (N10-007) — Question 66

A network technician receives a call from a user in the accounting department stating that Internet connectivity has been lost after receiving a new workstation. No other users in accounting are reporting similar issues. The network technician is able to ping the machine from the accounting department's router, but is not able to ping the machine from the IT network. Which of the following is MOST likely the cause?

Answer options

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

Correct answer: A

Explanation

The most likely cause of the issue is an incorrect default gateway, as this would prevent the workstation from communicating with devices on the IT network. A duplicate IP address would affect multiple users, and misconfigured OSPF or improper VLAN assignment would likely impact more than just one workstation, making them less likely causes in this scenario.
