Correct answers: A, C, D
Explanation
Network Intelligence Center provides tools that help monitor and troubleshoot networking issues. For this scenario, the Connectivity Tests feature helps identify connectivity problems between the two resources, Firewall Insights helps check for any blocking firewall rules, and Network Topology allows you to visualize network paths and interconnections. These tools are directly relevant to diagnosing the intermittent connectivity issue described.
- A. Correct.
The Connectivity Tests feature is designed to verify and diagnose reachability between two endpoints, making it a valuable tool to identify connectivity issues between the VM and the database instance.
- B. Incorrect.
The Performance Dashboard is not part of the Network Intelligence Center; it is unrelated to diagnosing connectivity issues in this scenario.
- C. Correct.
The Firewall Insights feature helps identify misconfigured or blocking firewall rules, which could be a potential cause of the connectivity issue.
- D. Correct.
The Network Topology feature provides a visual representation of network paths and connections, helping to identify potential misroutes or missing links between the resources.
- E. Incorrect.
While the DDoS Protection dashboard can monitor for attacks, it is not relevant to diagnosing an intermittent connectivity issue in this specific scenario.
