- A
Configure a service endpoint for Azure Storage on the VNet subnet and add a firewall rule allowing the VNet.
Why wrong: Service endpoints provide a direct route to the storage account from the VNet but the storage account's public endpoint is still available. This does not guarantee that only the VNet can access it if the firewall rule is bypassed or misconfigured.
- B
Deploy a private endpoint for the storage account in the same VNet and disable public network access on the storage account.
Correct. A private endpoint gives the storage account a private IP in the VNet. Disabling public network access ensures that only traffic via the private endpoint is allowed, blocking all internet traffic.
- C
Route all traffic from the VNet through an Azure Firewall and create a NAT rule to the storage account.
Why wrong: Azure Firewall does not provide fine-grained access control to a specific storage account's queue. It only filters traffic at the network layer, not at the PaaS service level.
- D
Generate a shared access signature (SAS) token with narrow permissions and require the web app to use that token.
Why wrong: SAS tokens grant access over the public endpoint and can be used from anywhere on the internet. This does not meet the requirement to block all public internet access.
Quick Answer
The correct configuration is to deploy a private endpoint for the storage account in the same VNet and disable public network access on the storage account. This works because a private endpoint assigns the Azure Queue Storage service a private IP address from your VNet, effectively bringing the storage account into the network and allowing traffic to flow securely over the Microsoft backbone. By then disabling public network access, you ensure that all access to the queue must traverse that private endpoint, blocking any public internet traffic and meeting the requirement that only the web application’s VM can reach the queue. On the AZ-500 exam, this scenario tests your understanding of network segmentation and private link services—a common trap is confusing service endpoints (which still allow public exposure) with private endpoints (which fully isolate the resource). Remember the mnemonic: “Private IP, public off” to lock down storage from the internet.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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.
A company stores sensitive job processing messages in Azure Queue Storage. They have a web application running on an Azure virtual machine in a VNet that reads and writes to the queue. The security team requires that only the web application's VM can access the queue, and all access from the public internet must be blocked. Which configuration should they 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
Deploy a private endpoint for the storage account in the same VNet and disable public network access on the storage account.
Option B is correct because deploying a private endpoint for the storage account in the same VNet assigns the storage account a private IP from the VNet, effectively bringing the service into the VNet. Disabling public network access then ensures that all traffic to the queue must traverse the private endpoint, blocking any public internet access. This meets the requirement that only the web application's VM can access the queue, as the private endpoint is accessible only from within that VNet.
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.
- ✗
Configure a service endpoint for Azure Storage on the VNet subnet and add a firewall rule allowing the VNet.
Why it's wrong here
Service endpoints provide a direct route to the storage account from the VNet but the storage account's public endpoint is still available. This does not guarantee that only the VNet can access it if the firewall rule is bypassed or misconfigured.
- ✓
Deploy a private endpoint for the storage account in the same VNet and disable public network access on the storage account.
Why this is correct
Correct. A private endpoint gives the storage account a private IP in the VNet. Disabling public network access ensures that only traffic via the private endpoint is allowed, blocking all internet traffic.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse service endpoints (which only extend VNet identity but leave the public endpoint exposed) with private endpoints (which fully remove public exposure), leading them to choose option A instead of B.
Detailed technical explanation
How to think about this question
A private endpoint uses a network interface with a private IP from the VNet, leveraging Azure Private Link to route traffic to the storage account over the Microsoft backbone network, bypassing the public internet. When public network access is disabled, the storage account's firewall rejects all traffic not originating from the private endpoint, even if the traffic includes a valid SAS token. In a real-world scenario, this setup is critical for compliance with regulations like PCI DSS that require network isolation for sensitive data.
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.
