- A
Enable a service endpoint on the on-premises network.
Why wrong: Service endpoints only extend Azure VNet identity to supported services and do not create private IP access from on-premises.
- B
Create a private endpoint for the storage account in an Azure VNet.
A private endpoint assigns the storage account a private IP address in a chosen Azure VNet, allowing access over private connectivity instead of the public internet. Because the on-premises application already reaches Azure through a site-to-site VPN, it can use that private path to access the endpoint when DNS is configured correctly. This meets the requirement to keep public access disabled while exposing the service privately.
- C
Peer the on-premises network directly to the storage account.
Why wrong: On-premises networks cannot be peered directly with Azure storage services, and peering is only between VNets.
- D
Use a shared access signature and leave public network access enabled.
Why wrong: A SAS controls authorization, but it does not satisfy the private-only network requirement.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. 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.
An on-premises application connected through a site-to-site VPN must read data from an Azure Storage account. Public network access is disabled on the storage account, and the storage service must be reachable only by a private IP address inside Azure. Which solution should the administrator implement?
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 an Azure VNet.
A private endpoint assigns the storage account a private IP address from an Azure VNet, allowing the on-premises application to connect over the site-to-site VPN using that private IP. This ensures the storage service is reachable only within Azure's private network, even with public network access disabled. The private endpoint uses Azure Private Link to securely expose the storage account into the VNet, making it accessible via the VPN without traversing the public internet.
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.
- ✗
Enable a service endpoint on the on-premises network.
Why it's wrong here
Service endpoints only extend Azure VNet identity to supported services and do not create private IP access from on-premises.
- ✓
Create a private endpoint for the storage account in an Azure VNet.
Why this is correct
A private endpoint assigns the storage account a private IP address in a chosen Azure VNet, allowing access over private connectivity instead of the public internet. Because the on-premises application already reaches Azure through a site-to-site VPN, it can use that private path to access the endpoint when DNS is configured correctly. This meets the requirement to keep public access disabled while exposing the service privately.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing service endpoints with private endpoints: candidates often choose service endpoints because they also provide secure connectivity, but service endpoints do not assign a private IP and require public network access to be enabled, making them unsuitable when the requirement is to use only a private IP address.
Detailed technical explanation
How to think about this question
Azure Private Link creates a network interface (NIC) in the VNet with a private IP from the subnet, mapped to the storage account's resource ID. Traffic from on-premises to the private endpoint flows over the site-to-site VPN, through the VNet, and directly to the storage account via the Microsoft backbone, bypassing the public endpoint entirely. This setup also supports DNS resolution where the storage account's FQDN resolves to the private IP within the VNet, ensuring no public internet 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.
