Google Professional Cloud Network Engineer Question 714
Select 3Google Cloud PlatformYour organization has deployed a multi-tier web application on Google Cloud using Compute Engine instances in multiple regions. You are tasked with ensuring high availability and identifying potential network bottlenecks using Google Cloud’s observability tools. Which of the following steps should you take to effectively monitor and troubleshoot the network performance of your application?
- A
Enable VPC Flow Logs for all VPC subnets and export them to Cloud Logging for analysis.
- B
Use Cloud Trace to visualize the latency and trace network requests across multiple regions.
- C
Set up a Cloud Monitoring uptime check to monitor the availability and latency of the application.
- D
Configure a custom metric in Cloud Monitoring to track the number of dropped packets in your VPC.
- E
Deploy a third-party network monitoring tool on top of your Google Cloud infrastructure.
Show answer and explanation
Correct answers: A, C, D
Explanation
To effectively monitor and troubleshoot network performance in Google Cloud, you should leverage Google Cloud’s native observability tools. VPC Flow Logs provide valuable insights into traffic patterns and bottlenecks, while Cloud Monitoring uptime checks help track application availability and latency. Custom metrics, such as tracking dropped packets, can provide additional insights tailored to your network's specific requirements. Relying on third-party tools is not necessary when Google Cloud provides comprehensive network monitoring capabilities.
- A. Correct.
Correct. Enabling VPC Flow Logs provides detailed information about traffic flowing through your VPC network, which is critical for identifying network bottlenecks and troubleshooting issues.
- B. Incorrect.
Incorrect. While Cloud Trace is useful for analyzing application-level latency, it is not specifically designed for monitoring network performance or bottlenecks.
- C. Correct.
Correct. Cloud Monitoring uptime checks are a recommended way to monitor the availability and latency of your application from different geographic locations, helping to identify potential network issues.
- D. Correct.
Correct. Configuring a custom metric in Cloud Monitoring to track dropped packets in your VPC allows you to proactively monitor and address network performance issues.
- E. Incorrect.
Incorrect. While third-party tools can provide additional insights, Google Cloud’s native observability tools (such as VPC Flow Logs, Cloud Monitoring, and Cloud Logging) are sufficient for most network performance monitoring needs.
