Google Professional Cloud Network Engineer Question 755
Single answerGoogle Cloud PlatformYou are a Cloud Network Engineer troubleshooting intermittent connectivity issues between two Virtual Machines (VMs) in different VPC networks connected via a VPC Network Peering. To identify the root cause, you decide to use Network Intelligence Center. Which tool or feature within Network Intelligence Center would be the most appropriate to determine if the issue is due to a firewall rule or route misconfiguration?
- A
Connectivity Tests
- B
Packet Mirroring
- C
Performance Dashboard
- D
Network Topology
Show answer and explanation
Correct answer: A
Explanation
The Connectivity Tests feature in Network Intelligence Center is specifically designed to diagnose connectivity issues between resources. It simulates traffic between endpoints and checks for potential misconfigurations in firewall rules, routes, and other network settings. In this scenario, it is the most appropriate tool to identify the root cause of the intermittent connectivity issue.
- A. Correct.
Connectivity Tests is the correct choice because it allows you to simulate traffic between the VMs and verify that the routes and firewall rules are configured correctly along the data path.
- B. Incorrect.
Packet Mirroring is used to capture and analyze packet-level data for advanced troubleshooting, but it is not the best tool for checking firewall or route misconfigurations.
- C. Incorrect.
Performance Dashboard focuses on monitoring metrics like latency and throughput, and does not provide specific insights into firewall rules or routing issues.
- D. Incorrect.
Network Topology visualizes the network structure and connectivity but does not offer detailed diagnostics for misconfigured routes or firewall rules.
