Google Professional Cloud Network Engineer Question 774
Select 3Google Cloud PlatformYou are a Cloud Network Engineer responsible for troubleshooting connectivity issues between a Virtual Machine (VM) in Google Cloud and an external on-premises server. Users have reported intermittent packet loss and high latency during peak hours. You decide to use the Network Performance Dashboard in the Google Cloud Console. Which of the following steps should you take to identify and analyze the issue using the Performance Dashboard?
- A
Navigate to the Performance Dashboard and review the 'Google-wide Packet Loss' metric to identify any network-wide issues.
- B
Check the 'Latency' metric in the Performance Dashboard to analyze delays in data transmission between the VM and the external server.
- C
Enable VPC Flow Logs on the VM's subnet to capture detailed traffic flows and inspect packet-level data.
- D
Use the Performance Dashboard to review 'Per-Region Packet Loss' metrics for the specific Google Cloud region hosting the VM.
- E
Configure a custom latency alert in the Performance Dashboard to detect future latency spikes in real-time.
Show answer and explanation
Correct answers: A, B, D
Explanation
The Performance Dashboard in Google Cloud is a critical tool for analyzing packet loss and latency issues. By reviewing key metrics such as 'Google-wide Packet Loss,' 'Latency,' and 'Per-Region Packet Loss,' you can identify whether the issue is related to Google’s network, latency between endpoints, or region-specific problems. While VPC Flow Logs and custom alerts are valuable, they are not features of the Performance Dashboard itself and require additional configuration.
- A. Correct.
Correct: The 'Google-wide Packet Loss' metric in the Performance Dashboard helps identify whether the issue is related to a broader Google network problem.
- B. Correct.
Correct: The 'Latency' metric in the Performance Dashboard is specifically designed to help analyze delays and identify high-latency periods.
- C. Incorrect.
Incorrect: While VPC Flow Logs can provide detailed packet-level information, they are not part of the Performance Dashboard and require separate configuration.
- D. Correct.
Correct: The 'Per-Region Packet Loss' metric provides region-specific data to help pinpoint issues specific to the region hosting the VM.
- E. Incorrect.
Incorrect: The Performance Dashboard does not support real-time custom alerting; alerts must be configured separately using Cloud Monitoring.
