The correct choice is a system-assigned managed identity because it is intrinsically tied to the lifecycle of the Azure resource—in this case, the storage account—and is automatically deleted when that resource is deleted. This identity is used to authenticate to Azure Key Vault for accessing the customer-managed key (CMK) used in server-side encryption (SSE), directly meeting the security team’s requirement that the identity be removed upon storage account deletion. On the AZ-500 exam, this scenario tests your understanding of managed identity types and their lifecycle behavior; a common trap is selecting a user-assigned managed identity, which persists independently and must be manually cleaned up. Remember the key distinction: system-assigned = tied to the resource’s birth and death; user-assigned = lives on its own. For a quick memory tip, think “system syncs with the resource’s lifespan—delete the storage, delete the identity.”
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.
An Azure Storage account is configured with server-side encryption (SSE) using a customer-managed key stored in Azure Key Vault. The security team requires that the storage account's identity be used to authenticate to the key vault for key access. Additionally, they want the identity to be automatically deleted when the storage account is deleted. Which type of identity should they assign to the storage account?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
System-assigned managed identity
A system-assigned managed identity is tied to the lifecycle of the Azure resource (the storage account) and is automatically deleted when the resource is deleted. This identity can be used to authenticate to Azure Key Vault for accessing the customer-managed key used in server-side encryption (SSE), satisfying the security team's requirement for automatic deletion upon storage account deletion.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
System-assigned managed identity
Why this is correct
This identity is linked to the storage account and automatically managed, meeting both requirements.

✗
User-assigned managed identity
Why it's wrong here
A user-assigned identity is managed separately and must be explicitly deleted; it does not auto-delete with the resource.
✗
Service principal
Why it's wrong here
Service principals require credential management (secrets or certificates) and are not automatically tied to resource lifecycle.
✗
Azure AD user account
Why it's wrong here
User accounts are for human users, not for Azure resource authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse user-assigned managed identities with system-assigned ones, overlooking the critical lifecycle coupling requirement that system-assigned identities are automatically deleted with the parent resource, while user-assigned identities persist independently.
Detailed technical explanation
How to think about this question
Under the hood, a system-assigned managed identity is represented as a service principal in Azure AD, but its lifecycle is fully managed by Azure Resource Manager (ARM). When the storage account is deleted, ARM automatically removes the corresponding service principal from Azure AD, ensuring no orphaned identities remain. This identity uses the IMDS (Instance Metadata Service) endpoint to obtain tokens for Key Vault access, supporting OAuth 2.0 client credentials grant flow without any credential rotation overhead.

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.
