A security administrator is troubleshooting network connectivity to an Azure virtual machine. The VM is behind a network security group (NSG) that has a deny-all inbound rule as the default. The administrator wants to quickly verify whether a specific TCP packet on port 3389 from their client IP (203.0.113.50) would be allowed or blocked by the NSG. Which Azure Network Watcher tool should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
Network Performance Monitor.
Network Performance Monitor is used to measure latency, packet loss, and performance across networks, not for rule validation.
Best answer
IP flow verify.
This tool simulates a packet and evaluates NSG rules to determine if the traffic is allowed or denied. It provides immediate feedback for troubleshooting NSG issues.
Distractor review
Next hop.
Next hop identifies the next hop type and IP address for a packet based on routing, but it does not evaluate NSG rules. It is used for route table diagnosis.
Distractor review
NSG diagnostics (flow logs).
NSG flow logs are used to capture and log all traffic flows for analytics, not for real-time validation of a specific simulated packet.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: IP flow verify. — IP flow verify in Azure Network Watcher is a diagnostic tool that checks whether a packet is allowed or denied to/from a virtual machine based on the NSG rules. You provide the source and destination IP, port, and protocol, and it returns the result, including which rule (if any) allowed or denied the traffic. It is the fastest way to test NSG rules without using actual traffic.
