- A
Enable the Microsoft.Storage service endpoint on the subnet.
A service endpoint extends the subnet identity to the storage service so the subnet can be authorized without a private IP address.
- B
Add the subnet to the storage account's virtual network rules.
The storage firewall must explicitly allow the subnet. Virtual network rules are how the storage account permits that subnet.
- C
Create a private endpoint for the storage account.
Why wrong: A private endpoint gives the service a private IP address, which the scenario explicitly says not to use.
- D
Assign the Reader role to the subnet.
Why wrong: Subnets do not receive Azure RBAC roles. Reader would not control storage network access anyway.
- E
Turn on blob soft delete.
Why wrong: Soft delete helps recovery of deleted blobs, but it does not restrict which networks can reach the storage account.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. 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 runs in a subnet and must reach a storage account over the public endpoint, but only that subnet should be allowed. The team does not want to use a private endpoint. Which two configurations should the administrator use? Select two.
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 the Microsoft.Storage service endpoint on the subnet.
Enabling the Microsoft.Storage service endpoint on the subnet (A) ensures that traffic from the subnet to the storage account's public endpoint is routed through the Azure backbone network and uses the source IP of the subnet's virtual network, allowing the storage account firewall to identify the traffic. Adding the subnet to the storage account's virtual network rules (B) then explicitly permits only that subnet's traffic, denying all other public endpoint access. Together, these two configurations restrict access to the storage account's public endpoint exclusively to the specified subnet without requiring a private endpoint.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Create a private endpoint for the storage account.
Why it's wrong here
A private endpoint gives the service a private IP address, which the scenario explicitly says not to use.
- ✗
Assign the Reader role to the subnet.
Why it's wrong here
Subnets do not receive Azure RBAC roles. Reader would not control storage network access anyway.
- ✗
Turn on blob soft delete.
Why it's wrong here
Soft delete helps recovery of deleted blobs, but it does not restrict which networks can reach the storage account.
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 private endpoints are required for subnet-specific access, but service endpoints plus virtual network rules achieve the same restriction on the public endpoint without the cost or complexity of private endpoints.
Trap categories for this question
Scenario analysis trap
A private endpoint gives the service a private IP address, which the scenario explicitly says not to use.
Detailed technical explanation
How to think about this question
Service endpoints extend the virtual network identity to Azure services, enabling the storage account firewall to evaluate traffic based on the subnet's virtual network ID rather than a public IP. The storage account's virtual network rules accept traffic only from subnets with the corresponding service endpoint enabled, and the firewall denies all other traffic by default when configured. This approach uses the storage account's public endpoint (e.g., *.blob.core.windows.net) but ensures traffic from the subnet stays within the Azure backbone, bypassing the internet.
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.
