Google Professional Cloud Network Engineer Question 787
Select 2Google Cloud PlatformYour organization has deployed several Compute Engine instances within a VPC. Recently, some users reported degraded performance when accessing an internal application hosted on one of the instances. You suspect there might be suboptimal network configurations or traffic bottlenecks. How can you use Network Analyzer to identify and resolve the issue?
- A
Use Network Analyzer to check for high network utilization warnings on the affected instance's subnet.
- B
Run Network Analyzer to detect if any firewall rules are unnecessarily blocking traffic to the application.
- C
Use Network Analyzer to identify potential issues with the BGP routing configuration for the VPC.
- D
Leverage Network Analyzer to ensure that the service account permissions for the affected instance are correctly configured.
Show answer and explanation
Correct answers: A, B
Explanation
Network Analyzer is a powerful tool for identifying network-related issues, such as high utilization or misconfigured firewall rules. In this scenario, high network utilization on the subnet or restrictive firewall rules could explain the degraded performance. BGP routing and IAM permissions are outside the scope of Network Analyzer's functionality.
- A. Correct.
Correct: Network Analyzer can identify high utilization warnings for subnets, which can help pinpoint potential traffic bottlenecks.
- B. Correct.
Correct: Network Analyzer can help detect firewall misconfigurations, such as rules that block or restrict traffic to the application.
- C. Incorrect.
Incorrect: Network Analyzer does not provide insights into BGP routing for the VPC. This would require using Cloud Router or other tools.
- D. Incorrect.
Incorrect: Network Analyzer does not analyze IAM or service account permissions. This would be addressed through IAM policies and permissions review.
