- A
Create a private endpoint and a private DNS zone for the storage account.
Why wrong: That would give the service a private IP and require DNS integration, which the requirement explicitly avoids.
- B
Enable a service endpoint for Microsoft.Storage on the subnet and restrict the storage firewall to that subnet.
A service endpoint extends the subnet identity to the Azure Storage service without creating a private IP address in the VNet. It also avoids DNS changes because clients continue to use the normal public endpoint name, while the storage firewall can be configured to allow only the selected subnet. This matches the requirement for subnet-only access while keeping the service on its public endpoint architecture.
- C
Allow access only from the VM public IP address.
Why wrong: That secures by public IP, not by subnet, and it breaks if the VM is replaced or its address changes.
- D
Place the storage account in the same resource group as the VM.
Why wrong: Resource-group placement does not control network access or restrict traffic to a subnet.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An application running on a VM in a subnet must access an Azure Storage account. The security team wants the storage account to accept traffic only from that subnet, but they do not want a private IP address in the VNet and they do not want to change DNS records. What should the administrator configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable a service endpoint for Microsoft.Storage on the subnet and restrict the storage firewall to that subnet.
Option B is correct because a service endpoint for Microsoft.Storage allows the subnet to send traffic to the storage account over the Azure backbone network using the storage account's public endpoint, without requiring a private IP address or DNS changes. The storage firewall then restricts access to only that subnet's traffic, meeting the security team's requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a private endpoint and a private DNS zone for the storage account.
Why it's wrong here
That would give the service a private IP and require DNS integration, which the requirement explicitly avoids.
When this WOULD be correct
This option would be correct if the question required the storage account to be accessible only from a specific VNet using a private IP address, and the candidate was allowed to manage DNS records (e.g., by creating a private DNS zone). For example: 'An application on a VM must access a storage account using a private IP to avoid traversing the internet. The team can update DNS records. What should they configure?'
- ✓
Enable a service endpoint for Microsoft.Storage on the subnet and restrict the storage firewall to that subnet.
Why this is correct
A service endpoint extends the subnet identity to the Azure Storage service without creating a private IP address in the VNet. It also avoids DNS changes because clients continue to use the normal public endpoint name, while the storage firewall can be configured to allow only the selected subnet. This matches the requirement for subnet-only access while keeping the service on its public endpoint architecture.

- ✗
Allow access only from the VM public IP address.
Why it's wrong here
That secures by public IP, not by subnet, and it breaks if the VM is replaced or its address changes.
When this WOULD be correct
If the question required restricting access to a storage account from a specific VM with a static public IP, and the security team was okay with using public IP addresses without subnet-level restrictions, then configuring the storage firewall to allow only that VM's public IP would be correct.
- ✗
Place the storage account in the same resource group as the VM.
Why it's wrong here
Resource-group placement does not control network access or restrict traffic to a subnet.
When this WOULD be correct
An administrator needs to apply the same tag to a storage account and a VM for cost tracking, and the question specifies that resources in the same resource group should inherit a policy requiring that tag.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Enable a service endpoint for Microsoft.Storage on the subnet and restrict the storage firewall to that subnet.Correct answer▾
Why this is correct
A service endpoint extends the subnet identity to the Azure Storage service without creating a private IP address in the VNet. It also avoids DNS changes because clients continue to use the normal public endpoint name, while the storage firewall can be configured to allow only the selected subnet. This matches the requirement for subnet-only access while keeping the service on its public endpoint architecture.
✗Create a private endpoint and a private DNS zone for the storage account.Wrong answer — click to see why▾
Why this is wrong here
The question explicitly states the security team does not want a private IP address in the VNet and does not want to change DNS records. A private endpoint assigns a private IP to the storage account within the VNet and requires a private DNS zone to resolve the storage account FQDN to that private IP, which violates both constraints.
★ When this WOULD be the correct answer
This option would be correct if the question required the storage account to be accessible only from a specific VNet using a private IP address, and the candidate was allowed to manage DNS records (e.g., by creating a private DNS zone). For example: 'An application on a VM must access a storage account using a private IP to avoid traversing the internet. The team can update DNS records. What should they configure?'
Why candidates choose this
Candidates may confuse private endpoints with service endpoints, thinking both provide subnet-level access control. They might also overlook the explicit constraints about private IP and DNS changes, focusing only on the requirement to restrict access to a subnet.
✗Allow access only from the VM public IP address.Wrong answer — click to see why▾
Why this is wrong here
The security team does not want to change DNS records, and using the VM's public IP address would require the storage account to accept traffic from that public IP, which is not restricted to the subnet and does not leverage Azure's network infrastructure for secure access.
★ When this WOULD be the correct answer
If the question required restricting access to a storage account from a specific VM with a static public IP, and the security team was okay with using public IP addresses without subnet-level restrictions, then configuring the storage firewall to allow only that VM's public IP would be correct.
Why candidates choose this
Candidates may think that restricting by public IP is a straightforward way to limit access, overlooking the requirement for subnet-level restriction and the desire to avoid public IP exposure.
✗Place the storage account in the same resource group as the VM.Wrong answer — click to see why▾
Why this is wrong here
Placing the storage account in the same resource group as the VM does not restrict network access; resource groups are logical containers and do not enforce network security.
★ When this WOULD be the correct answer
An administrator needs to apply the same tag to a storage account and a VM for cost tracking, and the question specifies that resources in the same resource group should inherit a policy requiring that tag.
Why candidates choose this
Candidates may mistakenly think that same resource group implies same network or security boundary, confusing logical grouping with network segmentation.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse service endpoints with private endpoints, assuming that any restriction to a VNet requires a private IP address, but service endpoints achieve subnet-level restriction using the public endpoint without private IPs or DNS changes.
Detailed technical explanation
How to think about this question
Service endpoints extend the VNet identity to Azure services by enabling the subnet to route traffic to the storage account over the Microsoft Azure backbone network, using the storage account's public endpoint. The storage firewall uses the source subnet's virtual network ID (not the VM's IP) to allow traffic, which is more stable than a public IP and avoids the need for private IPs or DNS changes. This approach is ideal for scenarios where you want to keep the storage account's public endpoint but restrict access to a specific VNet/subnet.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
