Google Professional Cloud Network Engineer Question 788
Select 3Google Cloud PlatformYour organization has deployed multiple Virtual Private Cloud (VPC) networks in Google Cloud. Recently, some services in a production environment started experiencing intermittent connectivity issues. As a Professional Cloud Network Engineer, you decide to use Network Analyzer to investigate. During the analysis, Network Analyzer flags warnings for suboptimal configurations and potential failures. Which of the following actions should you prioritize to address the warnings identified by Network Analyzer?
- A
Investigate and resolve flagged firewall rules that allow overly broad access to sensitive resources.
- B
Review and correct any flagged routes that create asymmetric routing for critical services.
- C
Ignore utilization warnings if the identified resources are not yet causing downtime.
- D
Ensure that all flagged instances with external IPs have valid IAM roles assigned.
- E
Resolve overlapping IP ranges between peered VPC networks flagged by Network Analyzer.
Show answer and explanation
Correct answers: A, B, E
Explanation
Network Analyzer helps identify network failures, suboptimal configurations, and utilization warnings across your Google Cloud environment. Issues such as overly broad firewall rules, asymmetric routing, and overlapping IP ranges are critical and can lead to connectivity failures or security vulnerabilities. These issues should be prioritized for resolution to ensure secure and optimal network performance. While utilization warnings are important, they are typically less critical than immediate connectivity or configuration problems.
- A. Correct.
This is correct. Overly broad firewall rules can create security risks and may lead to unintended access to sensitive resources. Network Analyzer flags these as a high-priority issue.
- B. Correct.
This is correct. Asymmetric routing can cause connectivity issues for services, especially when traffic paths are inconsistent. This is a common issue flagged by Network Analyzer.
- C. Incorrect.
This is incorrect. Although utilization warnings might not immediately cause downtime, they indicate potential capacity issues that should be addressed proactively. However, ignoring them is not a best practice.
- D. Incorrect.
This is incorrect. While IAM roles are important for permissions, Network Analyzer does not flag external IPs for missing roles. This is not relevant to resolving network failures or suboptimal configurations.
- E. Correct.
This is correct. Overlapping IP ranges between peered VPCs can cause routing conflicts, leading to connectivity failures. Resolving these overlaps is critical for maintaining network functionality.
