Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A storage account should accept traffic only from one subnet, but the team does not want to create a private IP address for the service in the virtual network. What should they enable?
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
User-assigned managed identity, because it controls subnet access.
Managed identities are for authentication, not for subnet-based network access control.
B
Distractor review
Blob soft delete, because it helps restrict where traffic comes from.
Soft delete protects deleted data, but it does not control network access or source subnet restrictions.
C
Best answer
Service endpoint, because it allows the subnet to access the storage service securely over the Azure backbone.
A service endpoint lets you restrict storage access to a specific subnet without creating a private IP for the service in the virtual network.
D
Distractor review
Private endpoint, because it is the only way to allow one subnet.
Private endpoints are not required when the goal is only to restrict access to a subnet without assigning a private IP to the service.
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 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: Service endpoint, because it allows the subnet to access the storage service securely over the Azure backbone. — A service endpoint is the right choice when you want to limit storage access to a specific subnet but do not need a private IP address for the service in the VNet. It keeps traffic on the Azure backbone and allows the storage firewall to recognize the subnet as an allowed source. This is different from a private endpoint, which creates a private IP for the service. Why others are wrong: Private endpoints are more restrictive and create a private IP, which the question says is not desired. Managed identities handle authentication, not network path control. Soft delete is a data protection feature and has no role in subnet-based access control.
