Google Professional Cloud Network Engineer Question 760
Select 3Google Cloud PlatformYour organization is experiencing performance degradation in a multi-tier application hosted on Google Cloud. You suspect that the issue is caused by abnormal traffic patterns between services. How can you use the Network Topology feature in Google Cloud to identify the root cause?
- A
Use Network Topology to visualize traffic flows and identify high-latency links between services.
- B
Leverage Network Topology to pinpoint specific VM instances with unusually high network throughput.
- C
Use Network Topology to monitor application logs for errors between services.
- D
Analyze the traffic matrix in Network Topology to identify unexpected traffic flows between services.
- E
Use Network Topology to directly configure firewall rules to block suspicious traffic.
Show answer and explanation
Correct answers: A, B, D
Explanation
Network Topology is a powerful tool for visualizing traffic patterns and troubleshooting network-related issues in Google Cloud. It helps identify high-latency links, pinpoint VMs with unusual throughput, and analyze unexpected traffic flows. However, it does not monitor application logs or directly configure firewall rules, as its primary purpose is to provide insights into network behavior.
- A. Correct.
Correct. Network Topology provides a visual representation of traffic flows and can help identify areas with high latency that may be causing performance issues.
- B. Correct.
Correct. Network Topology allows you to view metrics such as throughput for individual VM instances, helping you identify instances with abnormal traffic patterns.
- C. Incorrect.
Incorrect. Network Topology does not provide application log monitoring; it is focused on visualizing network traffic and flow data.
- D. Correct.
Correct. The traffic matrix in Network Topology can highlight unexpected traffic flows between services, which could indicate misconfigurations or security issues.
- E. Incorrect.
Incorrect. Network Topology is a visualization tool and does not allow direct configuration of firewall rules. Firewall rules must be managed via other tools or interfaces in Google Cloud.
