A VM in VNet B can reach a blob storage account through a private endpoint that was created in peered VNet A. The storage FQDN still resolves to the public IP when queried from VNet B, so the VM does not use the private path. What should the administrator change?

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

Distractor review

Add a service endpoint for Microsoft.Storage to VNet B

A service endpoint still uses the public endpoint and does not fix private-name resolution.

B

Best answer

Link the private DNS zone used by the private endpoint to VNet B

Private endpoint connectivity depends on DNS resolution returning the private IP address. In a peered virtual network, the DNS zone for the private endpoint must be linked so clients in VNet B resolve the storage name to the private address instead of the public one. Once that DNS path is corrected, traffic follows the private endpoint.

C

Distractor review

Disable the storage account firewall completely

Disabling the firewall would weaken security and still would not make VNet B resolve the private IP.

D

Distractor review

Move the storage account into VNet B

Storage accounts are not deployed inside a virtual network, so this is not a valid remediation.

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: Link the private DNS zone used by the private endpoint to VNet B — The problem is name resolution, not reachability. A private endpoint works only when clients resolve the storage FQDN to the private IP address. In a peered VNet, the private DNS zone associated with the endpoint must be linked to the other VNet so DNS queries return the private address there as well. After that, the VM in VNet B will use the private path correctly. Why others are wrong: A service endpoint would not resolve the storage name to a private IP, so it does not solve the issue. Turning off the firewall is a security anti-pattern and still leaves DNS unresolved. Moving the storage account into a VNet is not possible because Azure Storage is a PaaS service, not a resource placed inside a virtual network. DNS linkage is the correct fix.
