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.
A web app in a subnet must access a storage account through the storage account's public FQDN. Access must be limited to that single subnet, and the team does not want to deploy a private endpoint or manage private DNS records. Which configuration should you use?
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 on the subnet and allow that subnet in the storage account network rules.
Option B is correct because a service endpoint on the subnet allows the web app to access the storage account via its public FQDN while restricting access to that specific subnet. By enabling the Microsoft.Storage service endpoint on the subnet and adding the subnet's virtual network rule to the storage account's network rules, traffic from the subnet to the storage account's public endpoint is routed through the Azure backbone network, and only traffic from that subnet is permitted. This meets the requirement of limiting access without deploying a private endpoint or managing private DNS records.
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.
✗
Deploy a private endpoint and private DNS zone.
Why it's wrong here
That would require private IPs and DNS management, which the requirement explicitly wants to avoid.
✓
Enable a service endpoint on the subnet and allow that subnet in the storage account network rules.
Why this is correct
This keeps the public FQDN, restricts access to the subnet, and avoids private endpoint and DNS overhead.
Related concept
Read the scenario before looking for a memorised answer.
✗
Add a route table that sends storage traffic to an NVA.
Why it's wrong here
Routing traffic through an appliance does not restrict the storage service to one subnet.
✗
Place the storage account behind a public load balancer.
Why it's wrong here
A storage account is not secured this way, and a load balancer does not provide subnet-scoped access control.
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 service endpoints require private IPs or DNS changes, when in fact service endpoints work with the public FQDN and only require enabling the endpoint on the subnet and configuring the storage account's network rules.
Detailed technical explanation
How to think about this question
Service endpoints extend the virtual network identity to Azure services, allowing traffic from the subnet to the storage account's public endpoint to be routed over the Azure backbone rather than the public internet. The storage account's firewall rules use the subnet's virtual network ID (not the public IP) to allow or deny access, which means even if the subnet's public IP changes, access is maintained. In a real-world scenario, this is ideal for workloads like a web app that needs to upload logs to a storage account without exposing the storage account to the entire internet, while avoiding the cost and management overhead of private endpoints.

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.
