After a private endpoint for an Azure Blob Storage account is created, VMs in the same VNet still resolve the storage name to the public IP address. The administrator wants the name to resolve to the private endpoint address instead. What should be configured?
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
Link the private DNS zone for blob storage to the virtual network.
Private endpoints require private DNS so clients resolve the storage name to the endpoint's private IP instead of the public address. For Blob Storage, the relevant zone is the privatelink.blob.core.windows.net zone, and it must be linked to the VNet used by the clients. Once linked, Azure can answer DNS queries with the private endpoint address, which makes access work consistently without manual hosts file edits.
B
Distractor review
Create a route table that sends storage traffic to the private endpoint subnet.
Routing does not control name resolution, so a route table will not change the DNS answer.
C
Distractor review
Enable a service endpoint on the subnet that hosts the VMs.
Service endpoints do not make a storage account resolve to a private IP address.
D
Distractor review
Assign a public IP address to the private endpoint subnet.
Private endpoints are meant to stay private, and a public IP would not correct DNS behavior.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

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?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Link the private DNS zone for blob storage to the virtual network. — Private endpoints change how a service is reached, but clients still need DNS to resolve the service name to the new private IP. For Blob Storage, the private DNS zone privatelink.blob.core.windows.net should be linked to the virtual network so DNS queries return the private endpoint address. Without that linkage, VMs may continue resolving the public endpoint and bypass the private connectivity path. Why others are wrong: Route tables affect packet forwarding, not DNS responses. Service endpoints do not provide private IP-based resolution and are not the right control for private endpoint name resolution. Assigning a public IP would conflict with the goal of keeping access private and would not solve the DNS record problem.
