- A
Enable the Microsoft.Storage service endpoint on AppSubnet1 and restrict the storage account to selected virtual networks.
A service endpoint lets traffic from the subnet reach the storage account over the Azure backbone while the storage firewall can allow only that subnet. This matches the requirement to avoid private endpoints and DNS changes. The access is still limited to the approved subnet identity, which is what the storage firewall evaluates.
- B
Create a private endpoint and remove all public network access from the storage account.
Why wrong: This would require private DNS changes and a different access model, which the requirement explicitly excludes.
- C
Add a network security group rule that allows outbound TCP 443 to the storage account.
Why wrong: An NSG rule does not grant access to a storage account by itself and cannot replace storage firewall configuration.
- D
Enable peering between AppSubnet1 and the storage account network.
Why wrong: Storage accounts are not accessed through VNet peering, so this does not provide the needed control.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. 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.
An existing application in AppSubnet1 must access an Azure Storage account. The team does not want to add a private endpoint or change DNS records, but they do want to allow access only from AppSubnet1. Which configuration 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
Enable the Microsoft.Storage service endpoint on AppSubnet1 and restrict the storage account to selected virtual networks.
Option A is correct because enabling the Microsoft.Storage service endpoint on AppSubnet1 allows traffic from that subnet to be routed directly to the Azure Storage service over the Azure backbone network, bypassing the internet. By then restricting the storage account's firewall to 'selected virtual networks' and adding AppSubnet1's virtual network and subnet, access is limited exclusively to that subnet without needing a private endpoint or DNS changes.
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 the Microsoft.Storage service endpoint on AppSubnet1 and restrict the storage account to selected virtual networks.
Why this is correct
A service endpoint lets traffic from the subnet reach the storage account over the Azure backbone while the storage firewall can allow only that subnet. This matches the requirement to avoid private endpoints and DNS changes. The access is still limited to the approved subnet identity, which is what the storage firewall evaluates.

- ✗
Create a private endpoint and remove all public network access from the storage account.
Why it's wrong here
This would require private DNS changes and a different access model, which the requirement explicitly excludes.
- ✗
Add a network security group rule that allows outbound TCP 443 to the storage account.
Why it's wrong here
An NSG rule does not grant access to a storage account by itself and cannot replace storage firewall configuration.
- ✗
Enable peering between AppSubnet1 and the storage account network.
Why it's wrong here
Storage accounts are not accessed through VNet peering, so this does not provide the needed control.
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, assuming both require DNS changes, or they mistakenly think NSG rules alone can restrict inbound access to a PaaS service, when in fact the storage account firewall must be explicitly configured to accept traffic only from the specified subnet.
Detailed technical explanation
How to think about this question
Service endpoints work by adding the storage account's public IP prefixes to the subnet's route table, ensuring traffic to the storage service stays within the Azure backbone. The storage account firewall then inspects the source IP of incoming requests; when a service endpoint is enabled, the source IP is replaced with the virtual network's identity (the VNet and subnet ID), allowing the firewall to enforce subnet-level access. In a real-world scenario, this is ideal for legacy applications that cannot use private endpoints or DNS changes, as it provides a simple, network-level isolation without modifying the application.
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.
