A VM named VM1 cannot establish TCP 1433 connectivity to VM2. The administrator wants to test the exact flow, confirm whether an NSG allows or denies it, and identify the rule that applies if the flow is blocked. Which Network Watcher tool should be used?
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
Effective routes, because it shows the exact NSG rule name for blocked traffic.
Effective routes shows the routing table applied to a NIC, not the specific NSG rule that permits or denies a flow.
Best answer
IP flow verify, because it evaluates the 5-tuple and reports the matching allow or deny rule.
IP flow verify is designed to test a specific source, destination, protocol, and port combination against NSG rules. It returns whether the flow is allowed or denied and identifies the rule that matched, which makes it the right tool when you need to prove whether TCP 1433 is blocked and why.
Distractor review
Packet capture, because it automatically tells you which NSG rule denied the traffic.
Packet capture records packets for later inspection, but it does not directly evaluate NSG policy or identify the matching rule name.
Distractor review
Connection troubleshoot, because it only checks DNS name resolution.
Connection troubleshoot can test end-to-end reachability, but it is not the most precise tool for identifying the exact NSG rule that allows or denies the traffic flow.
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.

Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 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, because it evaluates the 5-tuple and reports the matching allow or deny rule. — IP flow verify is the best fit when you need to validate a specific traffic flow against NSG rules and identify the rule responsible for allow or deny behavior. In this case, the administrator knows the source VM, destination VM, protocol, and port. The tool evaluates that exact combination and reports the effective NSG decision, which is what the troubleshooting task requires. Why others are wrong: Effective routes helps with routing problems, not NSG rule identification. Packet capture is useful for packet-level analysis but does not directly tell you which NSG rule matched. Connection troubleshoot is broader connectivity testing, but it is less specific than IP flow verify when the goal is to confirm an NSG decision for a known TCP flow.
