Exhibit
Troubleshooting notes: - Source VM: vm-app01 - Destination VM: vm-sql01 - Port: TCP 1433 - Symptom: Connection times out - Goal: Verify whether the packet is allowed or denied by NSG rules and identify the rule name - Need a point-in-time check from the VM NIC perspective
Based on the exhibit, which Network Watcher tool should you use to determine whether an NSG allows or denies TCP 1433 traffic and which rule is responsible?
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.
A
Best answer
IP flow verify
IP flow verify is built to test a specific source, destination, protocol, and port against NSG rules.
B
Distractor review
Connection troubleshoot
Connection troubleshoot checks end-to-end connectivity, but it is less focused on rule-level allow and deny decisions.
C
Distractor review
Packet capture
Packet capture records packets for later analysis, but it does not directly identify the matching NSG rule.
D
Distractor review
Next hop
Next hop shows routing decisions, not whether an NSG permits or blocks a TCP 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 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
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 — IP flow verify is the Network Watcher feature that answers whether a specific flow is allowed or denied by NSG rules and identifies the rule that matches. Because the exhibit asks for a point-in-time check from the VM NIC perspective on TCP 1433, IP flow verify is the best fit. It directly evaluates the source, destination, protocol, and port against the effective security rules. Why others are wrong: Connection troubleshoot is broader and is better for testing overall path reachability, not just NSG rule matching. Packet capture is useful when you need packet-level evidence or retransmission details, but it does not give a direct allow/deny rule verdict. Next hop is for routing decisions and cannot tell you which NSG rule blocked traffic.
