- A
A system-assigned managed identity with Blob Data Contributor permissions on the container.
A system-assigned managed identity is tied directly to the App Service instance and disappears when the app is deleted, which satisfies the automatic cleanup requirement. Because shared key access is disabled and secrets are not allowed in configuration, the app should authenticate through Microsoft Entra ID using the managed identity. Assigning Blob Data Contributor at the appropriate scope allows upload access without storing credentials.
- B
A user-assigned managed identity with Blob Data Reader permissions on the storage account.
Why wrong: A user-assigned identity can be reused, but it does not disappear when the App Service is deleted, and Reader does not allow uploads.
- C
A shared access signature generated from the storage account key.
Why wrong: A SAS derived from the account key still depends on shared key access and introduces a secret that must be managed.
- D
A storage account access key stored in an application setting.
Why wrong: An access key is a long-lived secret and directly violates the no-secrets requirement in the scenario.
Quick Answer
The answer is a system-assigned managed identity with Blob Data Contributor permissions on the container. This is correct because a system-assigned managed identity is intrinsically tied to the App Service’s lifecycle—when the App Service is deleted, the identity is automatically removed, which instantly revokes access to Blob Storage without requiring any manual cleanup. This configuration allows the app to access blob storage without secrets, satisfying the requirement that shared key access is disabled and no secrets are stored in configuration files. On the AZ-104 exam, this scenario tests your understanding of Azure identity management and the principle of least privilege; a common trap is choosing a user-assigned managed identity, which persists independently and would not be removed with the app. Remember the memory tip: “System dies with the service” — a system-assigned identity is born and buried with its resource, making it the automatic choice for lifecycle-bound access.
AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. 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.
A web application runs in Azure App Service and uploads files to Azure Blob Storage. The storage account has shared key access disabled, and the app must not store secrets in configuration. If the App Service is deleted and recreated later, the storage access should be removed automatically with the app. What should you configure?

Correct answer & explanation
A system-assigned managed identity with Blob Data Contributor permissions on the container.
A system-assigned managed identity is tied to the App Service lifecycle, so when the app is deleted, the identity is automatically removed, revoking access to Blob Storage. Granting Blob Data Contributor permissions on the container allows the app to upload files without storing any secrets, satisfying the requirement that shared key access is disabled and no secrets are stored in configuration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

A system-assigned managed identity with Blob Data Contributor permissions on the container.
Why this is correct
A system-assigned managed identity is tied directly to the App Service instance and disappears when the app is deleted, which satisfies the automatic cleanup requirement. Because shared key access is disabled and secrets are not allowed in configuration, the app should authenticate through Microsoft Entra ID using the managed identity. Assigning Blob Data Contributor at the appropriate scope allows upload access without storing credentials.

- ✗
A user-assigned managed identity with Blob Data Reader permissions on the storage account.
Why it's wrong here
A user-assigned identity can be reused, but it does not disappear when the App Service is deleted, and Reader does not allow uploads.
- ✗
A shared access signature generated from the storage account key.
Why it's wrong here
A SAS derived from the account key still depends on shared key access and introduces a secret that must be managed.
- ✗
A storage account access key stored in an application setting.
Why it's wrong here
An access key is a long-lived secret and directly violates the no-secrets requirement in the scenario.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might choose a user-assigned managed identity (Option B) because it also avoids secrets, but they overlook the requirement that access must be automatically removed when the app is deleted, which only a system-assigned identity guarantees.

Detailed technical explanation
How to think about this question
System-assigned managed identities are created as a service principal in Azure AD, tied to the resource's lifecycle. When the App Service is deleted, Azure automatically cleans up the service principal, ensuring that any role assignments (like Blob Data Contributor) are also removed. This approach uses OAuth 2.0 tokens obtained from Azure AD to authenticate against Blob Storage, eliminating the need for any shared keys or secrets.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
