Exhibit
Storage account access requirements: - Access should be limited to subnet AppSubnet - The storage account should keep using its public endpoint - No private endpoint should be created - No private DNS zone should be managed - The workload is allowed to use Azure platform integration features
Based on the exhibit, which feature should you enable so the subnet can access the storage account without creating a private IP address in the VNet?
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
Private endpoint
A private endpoint creates a private IP in the VNet, which the requirement explicitly says not to do.
B
Best answer
Service endpoint
A service endpoint allows the subnet to reach the storage service over its public endpoint while restricting access by VNet identity.
C
Distractor review
VPN Gateway
A VPN gateway provides network transport, but it does not apply subnet-based storage firewall authorization.
D
Distractor review
Azure Firewall
Azure Firewall can filter traffic, but it does not by itself grant the storage account subnet-level service access.
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.

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 — A service endpoint is the right choice when you want to restrict Azure service access to a subnet without creating a private IP in the virtual network. The storage account remains on its public endpoint, but Azure recognizes traffic coming from the enabled subnet and can enforce network rules accordingly. This fits the requirement to avoid private endpoints and private DNS management. Why others are wrong: A private endpoint would violate the no-private-IP requirement. A VPN gateway only provides connectivity and does not change the storage account firewall model. Azure Firewall can inspect or control traffic, but it is not the Azure Storage network access feature that binds access to a subnet.
