Quick Answer
The answer is enabling Azure Storage Service Encryption (SSE) on the storage account, though the simplest approach is to do nothing because SSE is enabled by default for all new blobs. Azure Storage automatically encrypts data at rest using 256-bit AES encryption, a transparent process that requires no configuration or code changes, ensuring every blob written to the account is encrypted before being persisted to disk. On the AZ-500 exam, this concept tests your understanding of default security controls versus optional enhancements; a common trap is assuming you must manually enable encryption or that customer-managed keys (CMK) are required for compliance. Remember that SSE is the baseline—always on and free—while CMK and client-side encryption are advanced options for specific regulatory or key-control needs. A useful memory tip: "SSE is the default, no effort required; CMK is for control, not compliance."
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.
You need to ensure that all new blobs uploaded to an Azure Storage account are automatically encrypted at rest. What is the simplest way to achieve this?
Use Azure Disk Encryption on any VMs writing to storage.
Why wrong: Disk encryption does not encrypt blobs.
Implement client-side encryption in the application.
Why wrong: Client-side encryption is not automatic.
Enable Azure Storage Service Encryption (SSE) on the storage account.
SSE is enabled by default and encrypts all data.
Configure a customer-managed key in Azure Key Vault.
Why wrong: CMK is optional and not required for encryption.
Answer choices
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) on the storage account.
Option A is correct because Azure Storage automatically encrypts all data at rest using Azure Storage Service Encryption (SSE). This is enabled by default and requires no configuration. Option B is wrong because customer-managed keys (CMK) are optional for additional control. Option C is wrong because client-side encryption requires application changes. Option D is wrong because Azure Disk Encryption is for VM disks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
