- A
Add a storage firewall rule that allows the subnet's public IP range
Why wrong: Firewall rules control public access paths and do not place a private IP inside the virtual network.
- B
Configure a service endpoint for the subnet and keep public access enabled
Why wrong: Service endpoints extend identity to the service, but they do not create a private endpoint IP.
- C
Create a private endpoint for the storage account in the virtual network
A private endpoint gives the storage account a private IP address in the VNet and supports disabling public access.
- D
Peer the virtual network to the storage account's region
Why wrong: VNet peering connects networks, but it does not provide a private IP for the storage service.

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 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
✓
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.
When this WOULD be correct
If the requirement were to allow access from a specific subnet without assigning a private IP, and public access could remain enabled, then configuring a service endpoint for that subnet would be correct.
- ✓
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.
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.
✓Create a private endpoint for the storage account in the virtual networkCorrect answer▾
Why this is correct
A private endpoint gives the storage account a private IP address in the VNet and supports disabling public access.
✗Add a storage firewall rule that allows the subnet's public IP rangeWrong answer — click to see why▾
Why this is wrong here
This option only restricts access by IP address, but the storage account would still have a public IP and public endpoint, failing the requirement for a private IP address and disabled public network access.
★ When this WOULD be the correct answer
If the requirement was to allow access only from a specific subnet's public IP range while keeping the storage account publicly accessible from other IPs, a firewall rule would be appropriate.
Why candidates choose this
Candidates may think that a firewall rule is sufficient to restrict access to a single subnet, overlooking the need for a private IP and complete disabling of public access.
✗Configure a service endpoint for the subnet and keep public access enabledWrong answer — click to see why▾
Why this is wrong here
A service endpoint does not assign a private IP address to the storage account; it only allows traffic from the subnet via the public endpoint while keeping public access enabled, which violates the requirement to disable public network access.
★ When this WOULD be the correct answer
If the requirement were to allow access from a specific subnet without assigning a private IP, and public access could remain enabled, then configuring a service endpoint for that subnet would be correct.
Why candidates choose this
Candidates may confuse service endpoints with private endpoints, thinking both provide private connectivity, but service endpoints still use the public endpoint and do not disable public access.
✗Peer the virtual network to the storage account's regionWrong answer — click to see why▾
Why this is wrong here
VNet peering connects virtual networks, but does not assign a private IP to the storage account or disable public access. The storage account would still have a public endpoint, and peering alone does not restrict access to a single VNet.
★ When this WOULD be the correct answer
An administrator needs to connect two virtual networks in different regions to allow resources in one VNet to communicate with resources in the other VNet using private IP addresses, without requiring a VPN gateway or ExpressRoute.
Why candidates choose this
Candidates may confuse VNet peering with private connectivity, thinking that peering can provide private IP access to Azure services, or they may assume that peering inherently restricts public access.

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.
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.
