200-901 Question 200
Single answerA DevOps engineer is troubleshooting an issue where an application hosted on a private network is not able to access external web services. The network uses a proxy server for internet access and a VPN for secure remote access. What could be the most likely reason for the issue?
- A
The proxy server is misconfigured or not reachable.
- B
The VPN connection is blocking outbound traffic.
- C
The application is not configured to use the proxy server.
- D
The VPN tunnel is encrypting the traffic and bypassing the proxy.
Show answer and explanation
Correct answer: C
Explanation
In a network that relies on a proxy server for internet access, applications must be explicitly configured to use the proxy. If the application bypasses the proxy configuration, it will be unable to access external services. The VPN is irrelevant in this context as it primarily provides secure remote access and does not interfere with proxy configurations.
- A. Incorrect.
A misconfigured or unreachable proxy would cause issues, but this scenario specifically mentions that the issue is related to the application's configuration, making this less likely.
- B. Incorrect.
VPNs generally do not block outbound traffic unless explicitly configured to do so. This is less likely the root cause.
- C. Correct.
If the application is not configured to use the proxy server, it will not be able to connect to external web services, as the network relies on the proxy for internet access.
- D. Incorrect.
A VPN encrypts traffic but does not inherently bypass a proxy. The issue is more likely related to the application's configuration rather than VPN behavior.
