Google Professional Cloud Network Engineer Question 762
Select 3Google Cloud PlatformYour organization is experiencing intermittent performance issues in a distributed application deployed across multiple Google Cloud regions. You suspect network congestion might be the cause. You decide to use the Network Topology tool to investigate the issue. Which of the following steps and observations would help you identify the root cause using Network Topology?
- A
Use Network Topology to visualize traffic flows between regions and identify any high throughput links.
- B
Enable VPC Flow Logs to gather detailed packet-level data and integrate it with the Network Topology tool.
- C
Analyze the latency and packet loss metrics provided by Network Topology for inter-region traffic.
- D
Filter the visualized traffic flows in Network Topology by specific services or instance groups to pinpoint bottlenecks.
- E
Use Network Topology to configure firewall rules that restrict traffic between high-throughput regions.
Show answer and explanation
Correct answers: A, C, D
Explanation
Network Topology is a powerful tool for visualizing traffic flows, latency, and packet loss across your Google Cloud network. By identifying high-throughput links, analyzing latency/packet loss metrics, and filtering traffic flows by specific services or instance groups, you can effectively pinpoint network bottlenecks or congestion points. However, configuring firewall rules or integrating VPC Flow Logs are not part of its functionality.
- A. Correct.
Correct: Visualizing traffic flows between regions and identifying high-throughput links is a key feature of Network Topology and can help you detect potential congestion points.
- B. Incorrect.
Incorrect: While VPC Flow Logs provide detailed logging, they are not directly integrated into the Network Topology tool. This step would require separate analysis outside of Network Topology.
- C. Correct.
Correct: Network Topology provides latency and packet loss metrics, which are crucial indicators of network health and can help diagnose performance issues.
- D. Correct.
Correct: Filtering traffic flows by specific services or instance groups enables you to narrow down the scope of the investigation and identify potential bottlenecks more effectively.
- E. Incorrect.
Incorrect: Network Topology is a visualization and monitoring tool. It does not have the capability to configure firewall rules.
