This AZ-204 practice question tests your understanding of implement azure security. 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.
You have an Azure Storage account with a blob container. You need to grant a user read-only access to a specific blob for 24 hours without requiring them to authenticate with Microsoft Entra ID. What should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Generate a user delegation SAS token
A shared access signature (SAS) token with a user delegation key provides time-limited, delegated access to a specific blob. Option A is wrong because an access policy is used to manage SAS tokens but does not itself grant access. Option B is wrong because RBAC requires Entra ID authentication. Option D is wrong because storage account keys grant full access to the entire account.
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 user delegation SAS token
Why this is correct
User delegation SAS uses Entra ID credentials to sign the SAS and provides granular, time-limited access.
Related concept
Static NAT maps one inside address to one outside address.
✗
Provide the storage account access key
Why it's wrong here
Access keys provide full access to the storage account.
✗
Assign the Storage Blob Data Reader role
Why it's wrong here
RBAC roles require Entra ID authentication.
✗
Configure a stored access policy
Why it's wrong here
Stored access policies are used to manage SAS tokens but are not directly used to grant access.
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.
