Exhibit
Requirement summary: - Storage account: contosostore - Public network access: Disabled - AppSubnet VMs must reach the storage account by private IP - DNS for privatelink.blob.core.windows.net is already configured
Based on the exhibit, what should the administrator create so the storage account is reachable only by private IP from AppSubnet?
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
A private endpoint in AppSubnet for the storage account.
A private endpoint gives the storage account a private IP address in the VNet, which is exactly what the requirement calls for. Because public network access is disabled and DNS is already configured, this completes the private-only access path.
B
Distractor review
A service endpoint on AppSubnet for Microsoft.Storage.
Service endpoints still use the storage account's public endpoint, so they do not provide a private IP address.
C
Distractor review
A user-defined route to the storage account public IP.
Routes do not create private service addresses. They only influence how traffic is forwarded.
D
Distractor review
An application security group that contains the storage account.
Application security groups are for VM NICs in NSG rules, not for Azure Storage accounts.
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

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: A private endpoint in AppSubnet for the storage account. — A private endpoint is the Azure feature that places a private IP address for the storage account into the virtual network. That matches the requirement for private-only access from AppSubnet. Because DNS is already prepared for the privatelink name, the VMs can resolve the storage endpoint correctly and connect without using the public network path. Why others are wrong: Service endpoints still use the public storage endpoint. Routes do not turn a public PaaS endpoint into a private one. Application security groups apply only to VM NICs and NSG matching, not to storage services. The exhibit clearly asks for private IP access, which points to a private endpoint.
