300-445 Question 185
Single answerA user reports that they are unable to access a specific external website, but other users on the same network can access it without any issues. You are tasked with diagnosing the issue. After collecting diagnostic data, you find the following information:
- The user's device has an IP address assigned via DHCP.
- The default gateway is reachable from the user's device.
- The DNS server configured on the user's device is the same as other working devices.
- A traceroute to the external website stops at the VPN gateway.
What is the most likely cause of the issue?
- A
The user's DNS configuration is incorrect.
- B
The user's VPN client has a configuration issue.
- C
The external website is blocking the user's IP address.
- D
The user's default gateway is not functioning correctly.
Show answer and explanation
Correct answer: B
Explanation
The traceroute stopping at the VPN gateway indicates that the issue is related to the VPN connection. Since other devices on the same network are functioning properly, the most likely cause is a configuration issue specific to the user's VPN client, which prevents the traffic from reaching the destination.
- A. Incorrect.
The DNS configuration is the same as other working devices and is resolving correctly, so this is unlikely to be the cause.
- B. Correct.
Since the traceroute stops at the VPN gateway, and other users on the same network are not experiencing issues, this suggests the VPN client on the user's device may have a configuration issue.
- C. Incorrect.
There is no indication in the data provided that the external website is blocking the user's IP address. Additionally, this would not typically result in the traceroute stopping at the VPN gateway.
- D. Incorrect.
The default gateway is reachable from the user's device, so it is functioning correctly and is not the cause of the issue.
