Google Professional Cloud Network Engineer Question 757
Select 3Google Cloud PlatformYou are a network engineer for a company that hosts its web application on Google Cloud. Users have reported intermittent connectivity issues when accessing the application. You suspect that the problem might be related to network latency or packet loss. How can you use the Network Intelligence Center to troubleshoot this issue effectively?
- A
Use the Connectivity Tests tool to simulate traffic between the web application and user locations to identify potential network issues.
- B
Enable the Performance Dashboard in the Network Intelligence Center to monitor latency and packet loss metrics in real-time.
- C
Use the Firewall Insights feature to identify any misconfigured firewall rules that could be blocking user traffic.
- D
Leverage the Topology tool to visualize the network's architecture and identify potential bottlenecks or misconfigurations.
- E
Run the Log Analyzer feature in Network Intelligence Center to inspect HTTP request logs for patterns in connectivity failures.
Show answer and explanation
Correct answers: A, B, D
Explanation
The Network Intelligence Center provides a suite of tools for monitoring and troubleshooting network issues. In this scenario, tools like Connectivity Tests, Performance Dashboard, and Topology are crucial for identifying the root cause of intermittent connectivity issues related to latency and packet loss. Other tools like Firewall Insights or non-existent features (e.g., Log Analyzer) are either not relevant or not part of the Network Intelligence Center.
- A. Correct.
The Connectivity Tests tool allows you to simulate and troubleshoot network paths, helping you identify potential connectivity issues like firewall misconfigurations or routing problems.
- B. Correct.
The Performance Dashboard in the Network Intelligence Center provides real-time metrics such as latency and packet loss, which are directly relevant to the reported issue.
- C. Incorrect.
While Firewall Insights is useful for identifying misconfigured firewall rules, it is not directly applicable to diagnosing latency or packet loss issues.
- D. Correct.
The Topology tool helps visualize the architecture and can reveal network bottlenecks or misconfigurations, making it useful for troubleshooting connectivity problems.
- E. Incorrect.
The Log Analyzer is not a feature of the Network Intelligence Center and focuses on different aspects of application monitoring, not network-specific issues.
