- A
Enable a service endpoint for Microsoft.Storage on AppSubnet.
A service endpoint extends the subnet identity to the storage service while still using the public endpoint path.
- B
Configure the storage account firewall to allow AppSubnet.
Storage firewall rules can restrict access to that subnet once the subnet is allowed through a service endpoint.
- C
Create a private endpoint in AppSubnet.
Why wrong: A private endpoint would create a private IP, which the scenario explicitly says the administrator does not want.
- D
Disable public network access on the storage account.
Why wrong: Disabling public network access would block the public endpoint instead of allowing controlled public-endpoint access.
- E
Assign a public IP address to the storage account.
Why wrong: A public IP cannot be assigned to a storage account; it is a managed platform service, not a VM.
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 application in AppSubnet must access an Azure Storage account over the public endpoint, but only traffic from that subnet should be allowed, and the traffic should stay on the Microsoft backbone. The administrator does not want to create a private IP for the service. Which two actions should be taken? Select two.
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 a service endpoint for Microsoft.Storage on AppSubnet.
Enabling a service endpoint for Microsoft.Storage on AppSubnet (Option A) allows traffic from that subnet to reach the Azure Storage account over the Microsoft backbone, bypassing the public internet. This satisfies the requirement that traffic stays on the Microsoft backbone without needing a private IP for the service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Create a private endpoint in AppSubnet.
Why it's wrong here
A private endpoint would create a private IP, which the scenario explicitly says the administrator does not want.
- ✗
Disable public network access on the storage account.
Why it's wrong here
Disabling public network access would block the public endpoint instead of allowing controlled public-endpoint access.
- ✗
Assign a public IP address to the storage account.
Why it's wrong here
A public IP cannot be assigned to a storage account; it is a managed platform service, not a VM.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing service endpoints (which use the public endpoint but keep traffic on the backbone) with private endpoints (which assign a private IP and require disabling public access), leading candidates to incorrectly select Option C or D.

Detailed technical explanation
How to think about this question
Service endpoints extend the virtual network identity to the Azure service, allowing the storage account firewall to filter traffic based on the source subnet's virtual network ID. Traffic from AppSubnet to the storage account is routed through the Azure backbone network using optimal paths, not the public internet, even though the destination is the public endpoint. This is achieved by adding the subnet's virtual network ID to the storage account's firewall allow list, and the service endpoint ensures that traffic from the subnet is tagged with that ID.
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.
