The correct design is to enable managed identity and grant least-privilege access to the target resource. This works because Azure App Service’s managed identity provides the application with an automatically managed Azure AD identity, eliminating the need for any stored credentials in code or configuration. The app obtains an Azure AD token to authenticate directly to Azure Storage, and by assigning only the specific role required—such as ‘Storage Blob Data Reader’ for read-only access—you enforce least-privilege storage access. On the AZ-204 exam, this scenario tests your understanding of identity-based authentication versus key-based or connection-string approaches; a common trap is to default to storing a connection string in app settings. Remember the mnemonic “MIA” for Managed Identity Authentication: no keys, no secrets, just tokens.

This AZ-204 practice question tests your understanding of implement azure security. 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 developer is implementing least-privilege storage access. The application runs on Azure App Service and must avoid stored credentials. Which design should be used?

Correct answer & explanation
✓
Enable managed identity and grant least-privilege access to the target resource
Managed identity in Azure App Service allows the application to authenticate to Azure Storage without storing any credentials in code or configuration. By enabling a system-assigned or user-assigned managed identity, the app obtains an Azure AD token automatically, which is used to access the storage resource. Granting the managed identity only the required permissions (e.g., 'Storage Blob Data Reader' for read-only access) enforces least-privilege access, eliminating the need for stored secrets.
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.
✗
Use a shared administrator account
Why it's wrong here
Shared accounts remove accountability and violate least privilege.
✗
Disable authentication for the target resource
Why it's wrong here
Removing authentication is not a secure design.
✗
Store a client secret in source control
Why it's wrong here
Source-controlled secrets are exposed and difficult to rotate safely.
✓
Enable managed identity and grant least-privilege access to the target resource
Why this is correct
Managed identity lets Azure-hosted apps authenticate without stored secrets.
Clue confirmation
The clue word "least" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think storing a client secret in a configuration file (Option C) is acceptable if it's encrypted or in a secure location, but the question explicitly requires avoiding stored credentials, making managed identity the only correct choice.
Detailed technical explanation
How to think about this question
Under the hood, managed identity works by provisioning a service principal in Azure AD automatically tied to the App Service resource. The Azure Instance Metadata Service (IMDS) endpoint at 169.254.169.254 provides an access token for the managed identity, which the application can retrieve using the Azure Identity SDK (e.g., DefaultAzureCredential). This token is then used as a bearer token in the Authorization header for requests to Azure Storage, with RBAC roles evaluated at the storage account or container level to enforce granular permissions.

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.

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. A developer is implementing least-privilege storage access. The application runs on Azure App Service and must avoid stored credentials. Which design should be used? The design must avoid adding custom operational scripts.
medium
A.Use a shared administrator account
B.Disable authentication for the target resource
C.Store a client secret in source control
✓ D.Enable managed identity and grant least-privilege access to the target resource
Why D: Option D is correct because Azure Managed Identity provides an automatically managed identity in Azure AD that allows the App Service to authenticate to any service supporting Azure AD authentication without storing any credentials. By granting the managed identity only the specific permissions required (least-privilege) on the target storage resource (e.g., Storage Blob Data Reader), the application avoids stored credentials and eliminates the need for custom operational scripts. This aligns with the principle of zero standing credentials and is the recommended approach for Azure App Service.
Variation 2. You need to ensure that an Azure Functions app can access a blob in Azure Storage using its system-assigned managed identity. What should you do first?
easy
A.Configure CORS on the storage account
B.Enable the managed identity in the Function App
✓ C.Assign the Storage Blob Data Reader role to the managed identity at the storage account scope
D.Generate a SAS token for the blob
Why C: You must grant the managed identity the appropriate RBAC role on the storage account, such as Storage Blob Data Reader.
