Microsoft Azure Administrator Associate AZ-104 Practice Question

You can use Azure Network Watcher's IP flow verify feature to test whether traffic is allowed or denied to VM1 on a specific port. This tool considers all security rules applied to both the network interface and the subnet, providing a comprehensive assessment of the effective rules impacting the virtual machine. It helps identify if any security rules are blocking the traffic without the need to manually analyze each rule. Reviewing individual security settings, enabling logs, or performing packet captures are less efficient and may not immediately reveal the issue because they either provide too much data to sift through or don't directly indicate whether a rule is allowing or denying traffic.
