Google Professional Cloud Network Engineer Question 763
Select 4Google Cloud PlatformYour company has recently deployed several Compute Engine instances across two Google Cloud regions to handle increased web traffic. You need to analyze the network performance between these instances, including throughput, latency, and traffic flows, to optimize your architecture. Which of the following steps should you take to effectively use the Network Topology tool for this purpose?
- A
Navigate to the Network Topology section in the Google Cloud Console and filter the view by regions.
- B
Enable VPC Flow Logs for the relevant subnets to ensure detailed traffic data is available in Network Topology.
- C
Use the Network Topology tool to view the flow of traffic between resources and identify bottlenecks in real-time.
- D
Configure custom dashboards in Network Topology to display detailed per-instance latency metrics.
- E
Export Network Topology data to BigQuery for long-term analysis and trend identification.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Network Topology is a powerful tool in Google Cloud for visualizing and analyzing network traffic, throughput, and latency. To leverage its full potential, enabling VPC Flow Logs is essential for detailed data collection. Filtering views by regions and using the tool to examine traffic flows can help identify performance bottlenecks. Exporting data to BigQuery extends the tool's utility to long-term trend analysis. However, Network Topology does not support creating detailed dashboards directly; this requires integration with other tools.
- A. Correct.
Correct. Filtering by regions in Network Topology allows you to focus on the traffic flows and performance between specific resources in those regions.
- B. Correct.
Correct. VPC Flow Logs are required to populate detailed traffic data in Network Topology, making this a necessary step.
- C. Correct.
Correct. Network Topology provides a visual representation of traffic flows and helps identify potential network bottlenecks.
- D. Incorrect.
Incorrect. Network Topology does not support creating custom dashboards for per-instance latency metrics directly within the tool. This would require other monitoring tools like Cloud Monitoring.
- E. Correct.
Correct. Exporting data to BigQuery enables deeper analysis and historical trend identification, which can complement the real-time insights in Network Topology.
