The correct solution is to create a private endpoint for the storage account in the virtual network. This works because a private endpoint assigns the storage account a private IP address from the virtual network’s address space, using Azure Private Link to route all traffic securely over the Microsoft backbone rather than the public internet. By doing so, the storage service becomes accessible only from that specific virtual network, and you can disable public network access to fully isolate it. On the AZ-104 exam, this scenario tests your understanding of how private endpoints differ from service endpoints—a common trap is confusing the two, but remember that only a private endpoint provides a true private IP address and eliminates public exposure entirely. For a quick memory tip, think “private endpoint = private IP, service endpoint = public IP with a firewall rule.”
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 be accessible only from one virtual network, and the storage service must have a private IP address inside that network. Public network access should be disabled. Which solution should the administrator use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a private endpoint for the storage account in the virtual network
Option C is correct because a private endpoint assigns the storage account a private IP address from the virtual network's address space, using Azure Private Link to route traffic entirely over the Microsoft backbone. This ensures the storage account is accessible only from that virtual network and allows public network access to be disabled, meeting both 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.
✗
Add a storage firewall rule that allows the subnet's public IP range
Why it's wrong here
Firewall rules control public access paths and do not place a private IP inside the virtual network.
✗
Configure a service endpoint for the subnet and keep public access enabled
Why it's wrong here
Service endpoints extend identity to the service, but they do not create a private endpoint IP.
✓
Create a private endpoint for the storage account in the virtual network
Why this is correct
A private endpoint gives the storage account a private IP address in the VNet and supports disabling public access.

✗
Peer the virtual network to the storage account's region
Why it's wrong here
VNet peering connects networks, but it does not provide a private IP for the storage service.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing service endpoints (which still leave the public endpoint enabled and only provide source-side filtering) with private endpoints (which provide a private IP and fully disable public access).
Detailed technical explanation
How to think about this question
Azure Private Link uses a network interface (NIC) in the virtual network with a private IP from the subnet, and DNS resolution for the storage account's private endpoint FQDN (e.g., `storageaccount.privatelink.blob.core.windows.net`) resolves to that private IP. This ensures traffic never traverses the public internet, even if the storage account is in a different region. A common real-world scenario is securing a storage account for a database backup solution where compliance requires no public exposure.

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.
