- A
Enable AD DS authentication and configure a private endpoint for the storage account
Private endpoint provides a private IP in the virtual network, accessible via VPN, and AD DS authentication allows on-premises AD credentials.
- B
Enable AD DS authentication and configure a virtual network service endpoint
Why wrong: Service endpoints do not provide a private IP; the traffic still goes over the public endpoint.
- C
Enable AD DS authentication and configure a firewall rule to allow the on-premises VPN gateway public IP
Why wrong: Firewall rules with public IP expose the storage account to the internet; also, the VPN gateway IP might change.
- D
Enable Azure AD DS authentication and configure a service endpoint
Why wrong: Azure AD DS does not support on-premises AD credentials; it requires Azure AD DS domain-joined clients.
Quick Answer
The correct answer is to enable AD DS authentication and configure a private endpoint for the storage account. This works because on-premises Active Directory (AD) credentials require AD DS authentication on the storage account, which allows Azure Files to accept Kerberos tickets from your on-premises domain controllers over the site-to-site VPN. The private endpoint then assigns the storage account a private IP from your Azure virtual network, ensuring all traffic stays within the VPN tunnel and never touches the public internet. On the AZ-500 exam, this scenario tests your understanding of hybrid identity and network segmentation—a common trap is confusing Azure AD DS (cloud-only identities) with on-premises AD DS, or thinking firewall rules or service endpoints are sufficient when they still expose a public endpoint. Remember the key pairing: on-premises AD equals AD DS authentication, and private endpoint equals no internet exposure. A useful memory tip is “AD DS for on-prem creds, private endpoint for private path.”
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.
Your organization uses Azure Files shares with Azure AD DS authentication. You need to ensure that users can access the file share from on-premises Windows clients using their on-premises AD credentials, without exposing the storage account to the internet. The on-premises network is connected to Azure via a site-to-site VPN. What should you configure?
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 AD DS authentication and configure a private endpoint for the storage account
Option D is correct because to use on-premises AD credentials, you need to enable AD DS authentication on the storage account, and use a private endpoint for connectivity. Option A is wrong because Azure AD DS uses cloud-only identities, not on-premises AD. Option B is wrong because firewall rules with IP expose the storage account to the internet. Option C is wrong because service endpoints still use a 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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
