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 storage account must stay reachable through its public endpoint, but only Azure workloads in AppSubnet should be allowed to access it. No private IP is required. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A service endpoint on AppSubnet and a storage firewall VNet rule.
A service endpoint on AppSubnet extends the Azure backbone network to the subnet, allowing traffic to the storage account's public endpoint without a private IP. The storage firewall VNet rule then restricts access to only traffic originating from that specific subnet, meeting the requirement of public endpoint reachability with Azure workload-only access.
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.
✗
A private endpoint in AppSubnet.
Why it's wrong here
A private endpoint changes access to a private IP, which is not required because the public endpoint must remain in use.
✓
A service endpoint on AppSubnet and a storage firewall VNet rule.
Why this is correct
Service endpoints let the subnet access the storage account securely through its public endpoint, and the firewall can restrict access to that subnet.
Related concept
Read the scenario before looking for a memorised answer.
✗
A VPN gateway between AppSubnet and the storage account.
Why it's wrong here
A VPNgateway is for network-to-network connectivity, not for restricting a storage account to one Azure subnet.
✗
A public IP address on the storage account.
Why it's wrong here
Storage accounts do not use a customer-assigned public IP for subnet scoping or access restriction.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse private endpoints (which remove public endpoint access) with service endpoints (which preserve public endpoint access while restricting traffic), leading them to choose the private endpoint option despite the explicit requirement to keep the public endpoint reachable.
Detailed technical explanation
How to think about this question
Service endpoints use the Azure backbone to route traffic from the subnet to the storage account's public IP, bypassing the internet, and the VNet rule in the storage firewall evaluates the source IP of the request against the subnet's virtual network identifier. This approach does not require a private IP, keeping the storage account's public endpoint active for other permitted traffic if needed. In real-world scenarios, this is often used for cost-effective, secure access from PaaS services like Azure VMs or App Service without deploying private endpoints.

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.
