AZ-104 Manage Azure Identities and Governance Practice Question
This AZ-104 practice question tests your understanding of manage azure identities and governance. 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.
Exhibit
Web app configuration:
- Name: orders-web
- Current authentication method: client secret stored in application settings
- Requirement: Access Azure resources without storing credentials in the app
- Additional requirement: When the app is deleted, the identity should be removed automatically.
Based on the exhibit, which identity should the administrator enable to remove the secret from app settings and have the identity disappear automatically when the app is deleted?
Web app configuration:

- Additional requirement: When the app is deleted, the identity should be removed automatically.
A
User-assigned managed identity
Why wrong: A user-assigned identity can be reused across resources, but it does not automatically disappear when one app is deleted.
B
Service principal with a client secret
Why wrong: A service principal still requires a secret or certificate to be managed, which does not remove credential storage from the app.
C
System-assigned managed identity
A system-assigned managed identity is tied directly to the Azure resource, so it is created with the app and removed when the app is deleted. It is the best fit when you want to eliminate stored secrets and keep the identity lifecycle aligned to one resource.
D
Shared access signature
Why wrong: A SAS token is for scoped storage access, not for giving a web app a general Azure identity.

Correct answer & explanation
✓
System-assigned managed identity
The system-assigned managed identity is tied directly to the lifecycle of the Azure resource (e.g., an App Service). When you enable it, Azure automatically creates a service principal in Azure AD for that resource, and you can use the identity to access Azure Key Vault without storing secrets in app settings. When the resource is deleted, the system-assigned managed identity and its corresponding service principal are automatically removed, eliminating the need for manual cleanup.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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, assuming both are automatically deleted with the resource, but only the system-assigned identity is tied to the resource's lifecycle.
Detailed technical explanation
How to think about this question
Under the hood, a system-assigned managed identity uses the Azure Instance Metadata Service (IMDS) endpoint (169.254.169.254) to acquire OAuth 2.0 tokens for authenticating to Azure AD. The identity is represented as a service principal in Azure AD with a lifecycle that mirrors the parent resource—when the resource is deleted, Azure automatically removes the service principal via a background cleanup process. This is particularly useful in ephemeral environments like Azure DevOps deployment slots, where you want identities to be created and destroyed without manual intervention.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
