Google Professional Cloud Network Engineer Question 768

Select 3Google Cloud Platform

You are a network engineer managing a hybrid cloud environment. A VM instance in a Google Cloud VPC is unable to communicate with an on-premises server over a VPN connection. You suspect there might be an issue with the VPC route or firewall configuration. Which of the following steps should you take using Google Cloud's Connectivity Tests to identify the root cause of the issue?

  1. A

    Run a Connectivity Test from the VM instance to the on-premises server and analyze the hop-by-hop results for potential dropped packets.

  2. B

    Verify that the Connectivity Test path includes the correct Cloud Router and VPN tunnel.

  3. C

    Use the Connectivity Test to automatically resolve the issue by modifying the VPC's firewall rules.

  4. D

    Check the Connectivity Test results for any missing or misconfigured routes in the VPC.

  5. E

    Use Connectivity Tests to validate if the on-premises server is reachable by sending ICMP pings.

Correct answers: A, B, D

Explanation

Connectivity Tests in Google Cloud are powerful tools for diagnosing network connectivity issues. They allow you to simulate and analyze paths between endpoints, highlighting potential issues such as dropped packets, misconfigured routes, or missing firewall rules. By analyzing the test results, you can pinpoint the root cause of connectivity failures. However, Connectivity Tests are diagnostic tools and do not make automatic configuration changes or send real packets like ICMP pings.

  • A. Correct.

    Correct. Connectivity Tests provide hop-by-hop analysis of the path, helping identify where packets might be dropped due to misconfigurations.

  • B. Correct.

    Correct. For hybrid connectivity, the path should traverse through the correct Cloud Router and VPN tunnel. Connectivity Tests can verify these components.

  • C. Incorrect.

    Incorrect. Connectivity Tests do not have the capability to automatically change configurations. They are diagnostic tools only.

  • D. Correct.

    Correct. Connectivity Tests highlight missing or misconfigured routes, which are common causes of connectivity issues.

  • E. Incorrect.

    Incorrect. Connectivity Tests do not send ICMP pings; they simulate packet flows based on the configuration of Google Cloud's network.
