Explanation

To effectively troubleshoot and analyze network issues, you need to enable and review logs specific to the components in use. VPC Flow Logs provide visibility into subnet traffic, Cloud NAT logs give insights into NAT behavior, and Cloud VPN logs help diagnose issues with VPN tunnels. Firewall Insights and Cloud DNS logging are valuable tools but are not directly relevant to the troubleshooting of the specified network components in this scenario.

  • A. Correct.

    Correct: Enabling VPC Flow Logs allows you to capture metadata about traffic flowing into and out of your subnets, which is essential for troubleshooting and performance analysis.

  • B. Correct.

    Correct: Enabling Cloud NAT logging provides logs on NAT usage, such as translation information and errors, making it critical for troubleshooting NAT-specific issues.

  • C. Incorrect.

    Incorrect: Firewall Insights is used for analyzing firewall rule effectiveness, not troubleshooting general network components like Cloud VPN or NAT.

  • D. Correct.

    Correct: Cloud VPN logging captures tunnel connection information and packet statistics, which are crucial for identifying VPN issues.

  • E. Incorrect.

    Incorrect: Cloud DNS logging is used for analyzing DNS query patterns, which is unrelated to troubleshooting Cloud VPN, Cloud NAT, or VPC traffic.
