A VM cannot connect to another VM on TCP 1433. You need to determine whether an NSG is blocking the flow and identify which rule applies. Which Network Watcher tool should you 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
Packet capture
Packet capture records traffic for analysis, but it is not the fastest way to determine which NSG rule allows or denies a specific flow.
Best answer
IP flow verify
IP flow verify is the Network Watcher feature that tests a specific source, destination, protocol, and port against NSG rules. It shows whether the traffic is allowed or denied and which rule is responsible.
Distractor review
Connection troubleshoot
Connection troubleshoot is useful for end-to-end connectivity checks, but IP flow verify is the better tool when the specific goal is to see NSG rule impact.
Distractor review
Effective routes
Effective routes help inspect routing decisions, not NSG filtering. They do not tell you which security rule is blocking the TCP session.
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 right diagnostic tool when you need to check whether a specific flow is allowed or denied by an NSG and which rule causes the decision. By entering the source, destination, protocol, and port, you can quickly see the effective security result for that traffic path. This is especially useful when connectivity fails and you need to separate routing issues from security filtering. Why others are wrong: Packet capture is valuable for deep packet analysis, but it is more work than necessary for simple NSG verification. Connection troubleshoot tests connectivity end to end, but it is not as focused on identifying the exact NSG rule. Effective routes show route selection and are unrelated to packet filtering by security rules.
