The answer is to set the public access level to private and assign RBAC roles to users. This configuration is correct because it first disables all anonymous traffic at the container level, then uses Azure AD authentication and role-based access control to ensure only authenticated users from your Microsoft Entra tenant can read blobs. On the Microsoft Azure Developer Associate AZ-204 exam, this scenario tests your understanding of the layered security model for Azure Storage, specifically the distinction between network-level controls and identity-based access. A common trap is choosing firewall rules or SAS tokens—firewalls only control network traffic, not user identity, while SAS tokens can be shared externally, breaking the tenant-only restriction. Access keys are also wrong because they grant full account-level access without user-specific permissions. Memory tip: think "Private + RBAC = Tenant Only"—private shuts the door, RBAC checks the ID.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. 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.
You need to restrict access to an Azure Storage blob container so that only users from your Microsoft Entra tenant can read blobs, and deny all other access including anonymous traffic. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set public access level to private and assign RBAC roles to users
Option D is correct because disabling anonymous access and enabling Azure AD authentication with RBAC ensures only authenticated users from your tenant can access blobs. Option A is wrong because SAS tokens can be shared externally. Option B is wrong because firewall rules do not authenticate users. Option C is wrong because access keys provide full access, not user-specific.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Generate a shared access signature (SAS) for the container
Why it's wrong here
SAS tokens can be shared and do not restrict to tenant users.
✓
Set public access level to private and assign RBAC roles to users
Why this is correct
This ensures only authenticated users from your tenant can access blobs.
Related concept
Static NAT maps one inside address to one outside address.
✗
Configure a network firewall to allow only your tenant's IP range
Why it's wrong here
IP-based rules do not authenticate users.
✗
Use storage account access keys and distribute them to users
Why it's wrong here
Access keys grant full account access and are not user-specific.
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.
