- A
Create a private endpoint for the file service in VNet-App.
A private endpoint places the storage service on a private IP in the virtual network.
- B
Create and link the private DNS zone privatelink.file.core.windows.net to VNet-App.
This lets the VM resolve the standard file endpoint name to the private endpoint address.
- C
Disable public network access on the storage account.
Disabling public access ensures the storage account is not reachable through the internet path.
- D
Enable a service endpoint for Microsoft.Storage on the subnet instead of a private endpoint.
Why wrong: A service endpoint keeps the public endpoint model and does not create a private IP address.
- E
Grant the VM's managed identity the Storage File Data SMB Share Reader role to create the private path.
Why wrong: RBAC controls authorization, but it does not create private connectivity or DNS resolution.
Quick Answer
The answer is to disable public network access on the storage account, create a private endpoint in VNet-App, and configure private DNS zone integration. This trio of actions works because a private endpoint assigns a private IP address from your virtual network directly to the Azure Files service, allowing the Windows VM to reach the file share over a private IP without traversing the public internet. Disabling public access ensures the storage account is unreachable through its public endpoint, while private DNS zone integration automatically resolves the file share name to the private IP, eliminating the need for custom host-file entries. On the AZ-104 exam, this scenario tests your understanding of network isolation and DNS resolution for PaaS services, often appearing as a multi-select question where a common trap is forgetting the DNS zone step or assuming a service endpoint suffices. Remember the mnemonic “P-D-D” for Private endpoint, Disable public access, and DNS integration to lock in the three required actions.
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.
A Windows VM in VNet-App must access an Azure Files share over a private IP address. The storage account must not be reachable through its public endpoint, and the VM should resolve the file share name without custom host-file entries. Which three actions are required? Select three.
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 file service in VNet-App.
Option A is correct because a private endpoint assigns a private IP address from VNet-App to the Azure Files service, enabling the VM to access the file share over a private IP without traversing the public internet. This is required to meet the requirement that the storage account must not be reachable through its public endpoint.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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, thinking both provide private IP access, but service endpoints only provide a public endpoint route through the VNet and do not block public internet access.
Detailed technical explanation
How to think about this question
A private endpoint uses a network interface with a private IP from the VNet subnet, and traffic to the storage account is routed through the Microsoft backbone network. The private DNS zone `privatelink.file.core.windows.net` must be linked to the VNet so that the VM's DNS resolution returns the private IP instead of the public endpoint, avoiding the need for custom host-file entries. Disabling public network access on the storage account ensures that only traffic through the private endpoint is accepted, enforcing the private-only access requirement.
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.
