This AZ-204 practice question tests your understanding of implement azure security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: jWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).. 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 API receives JWT access tokens from Microsoft Entra ID. Which two token properties should the API validate before accepting a request? The team wants the control to be enforceable during normal operations.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Issuer and signature are valid for the trusted tenant
Option A is correct because validating the issuer and signature ensures the JWT was issued by the trusted Microsoft Entra ID tenant and has not been tampered with. The issuer claim (iss) must match the tenant-specific issuer URL (e.g., https://login.microsoftonline.com/{tenant-id}/v2.0), and the signature must be verified using the public keys from the OpenID Connect metadata endpoint. This is a fundamental security requirement for any API that accepts tokens from Entra ID.
Key principle: JWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Issuer and signature are valid for the trusted tenant
Why this is correct
Issuer and signature validation confirms the token came from the expected identity provider.
Related concept
JWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).
✗
The user's display name is present
Why it's wrong here
Display name is not a security validation control.
✓
Token audience matches the API application ID URI or client ID
Why this is correct
The audience proves the token was issued for this API.
Related concept
JWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).
✗
The token was sent in a query string
Why it's wrong here
Bearer tokens should not be accepted because they appear in query strings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think validating the user's display name (Option B) is necessary for authorization, but token validation is about verifying the token's authenticity and intended audience, not user attributes.
Detailed technical explanation
How to think about this question
Token validation follows the OAuth 2.0 and OpenID Connect specifications, where the API must check the iss, aud, and exp claims, and verify the RSA or ECDSA signature using the JWKS endpoint (e.g., https://login.microsoftonline.com/{tenant}/discovery/v2.0/keys). A subtle behavior is that the aud claim must match the API's application ID URI (e.g., api://{client-id}) or the client ID exactly; a mismatch allows token replay across different APIs. In real-world scenarios, failing to validate the audience can lead to a token issued for Microsoft Graph being accepted by a custom API, causing unauthorized access.
KKey Concepts to Remember
JWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).
Issuer validation confirms the token originated from the expected identity provider.
Signature validation ensures the token's integrity and authenticity.
Audience validation ('aud' claim) confirms the token is intended for the specific API.
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
JWTs from Microsoft Entra ID contain claims like 'iss' (issuer) and 'aud' (audience).
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.
