The correct answer is to enable Azure Storage Service Encryption (SSE) and use Microsoft Entra ID for authentication. SSE is enabled by default for all Azure storage accounts, automatically encrypting data at rest in Table Storage using 256-bit AES encryption, while Microsoft Entra ID provides role-based access control (RBAC) to ensure only authorized users can access the data. On the AZ-204 exam, this scenario tests your understanding of built-in platform encryption versus client-side options and the importance of identity-based access control; a common trap is choosing client-side encryption or shared access signatures, but the exam emphasizes that SSE handles at-rest encryption natively and Entra ID enforces fine-grained permissions. Remember the key pairing: SSE for encryption at rest, Entra ID for access control—think of it as “SSE secures the data, Entra ID secures the door.”
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure storage. 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 are developing an application that stores sensitive user data in Azure Table Storage. You need to ensure that data is encrypted at rest and that only authorized users can access it. What should you implement?
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 Service Encryption (SSE) and use Microsoft Entra ID for authentication.
Option B is correct because Azure Storage Service Encryption (SSE) is enabled by default for all storage accounts, encrypting data at rest. Additionally, using Microsoft Entra ID (formerly Azure AD) for authentication provides fine-grained access control via RBAC. Option A is wrong because client-side encryption is possible but not required; SSE already provides at-rest encryption. Option C is wrong because shared access signatures (SAS) provide delegated access but do not enforce RBAC. Option D is wrong because Azure Information Protection is a data classification solution, not for encryption.
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.
✗
Apply Azure Information Protection labels to the storage account.
Why it's wrong here
Azure Information Protection is for data classification, not encryption.
✓
Enable Azure Storage Service Encryption (SSE) and use Microsoft Entra ID for authentication.
Why this is correct
SSE encrypts data at rest; Entra ID provides RBAC for access control.
Related concept
Static NAT maps one inside address to one outside address.
✗
Implement client-side encryption using the Azure Storage SDK and manage keys via Azure Key Vault.
Why it's wrong here
Client-side encryption is optional; SSE already encrypts data at rest.
✗
Use shared access signatures (SAS) with a stored access policy to limit access to the data.
Why it's wrong here
SAS provides delegated access but does not enforce RBAC.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your application stores sensitive data in Azure Table Storage. You need to encrypt the data at rest. What should you do?
medium
A.Implement client-side encryption using Azure Key Vault.
B.Enable server-side encryption with customer-managed keys in Azure Key Vault.
✓ C.No action needed; Azure Storage Service Encryption (SSE) is enabled by default.
D.Enable Azure Disk Encryption on the virtual machines accessing the storage.
Why C: Option C is correct because Azure Storage Service Encryption (SSE) automatically encrypts all data at rest in Azure Table Storage using 256-bit AES encryption, and it is enabled by default for all new and existing storage accounts. Since the question asks about encrypting data at rest and does not specify a need for customer-managed keys or client-side control, the default SSE meets the requirement without any additional configuration.
