- A
Use Azure AD authentication with storage account access keys.
Why wrong: Access keys are shared keys; Azure AD authentication is supported but still requires key-based access for certain operations.
- B
Enable Azure Storage firewall, deny access from all networks, and add a private endpoint. Then assign a managed identity to the VMs and grant it the necessary RBAC role.
This configuration ensures access only from authorized VMs using managed identity, eliminating shared keys.
- C
Configure a storage account key and distribute it to the applications.
Why wrong: Using a storage account key is a shared key approach, not recommended for secure access without keys.
- D
Generate a SAS token with IP restrictions and embed it in the application code.
Why wrong: SAS tokens are shared secrets and can be leaked; they also require token management.
Quick Answer
The correct answer is to enable the Azure Storage firewall, deny access from all networks, add a private endpoint, assign a managed identity to the VMs, and grant the necessary RBAC role. This configuration works because the private endpoint brings the storage account into the virtual network, eliminating public internet exposure, while the managed identity provides a secure, password-free identity for the VM to authenticate directly to Azure Storage without shared keys or SAS tokens. On the AZ-500 exam, this scenario tests your understanding of the principle of least privilege and the shift from key-based to identity-based access—a common trap is choosing shared access keys or SAS tokens, which are explicitly forbidden by the requirement. Remember the mnemonic “PIM” for Private endpoint, Identity (managed), and Minimal network access (firewall deny all) to lock down storage without keys.
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 company uses Azure Storage to store sensitive customer data. You need to ensure that only authorized applications running on Azure VMs can access the storage account without using shared keys or SAS tokens. 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 Azure Storage firewall, deny access from all networks, and add a private endpoint. Then assign a managed identity to the VMs and grant it the necessary RBAC role.
Option B is correct because Azure Storage firewall with service endpoints or private endpoints, combined with managed identity, allows secure access without shared keys or SAS tokens. Option A (storage account key) is a shared key. Option C (SAS token) is a shared access signature. Option D (access keys) are shared keys.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
