The answer is to validate the 'tid' claim against a list of allowed tenant IDs in your application code. This is the recommended approach because the 'tid' claim in an Azure AD token explicitly contains the tenant ID of the user's home directory, making it a precise and reliable value for restricting multi-tenant Azure AD app access to specific tenants. On the AZ-204 exam, this tests your understanding of token validation and claims-based authorization, often appearing as a distractor where you might confuse the 'iss' (issuer) claim with 'tid'—remember that while 'iss' includes the tenant ID, it also contains other metadata, making 'tid' the cleaner, explicit choice. A common trap is assuming tenant-level restrictions or user assignment settings in the Azure portal will suffice, but those lack the granular, code-level control needed for a multi-tenant app. For your memory tip: think "TID for Tenant ID"—it's the direct, single-purpose claim that keeps your app locked to only the tenants you trust.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. 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.
You have a multi-tenant application that uses Azure AD (Microsoft Entra ID) for authentication. You want to allow only specific tenants to access your app. What is the recommended approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
In the application code, validate the 'tid' claim against a list of allowed tenant IDs.
The recommended approach is to validate the 'tid' (tenant ID) claim in the token after validation, and compare it against a list of allowed tenants. Option B is correct. Option A is wrong because user assignment requires each tenant to assign users, which is not flexible. Option C is wrong because tenant restrictions are set at the tenant level, not the app. Option D is wrong because the 'iss' claim includes the tenant ID, but it's better to use 'tid' as it's explicit.
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.
✓
In the application code, validate the 'tid' claim against a list of allowed tenant IDs.
Why this is correct
This is the standard pattern for multi-tenant app tenant restriction.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure the app manifest to require user assignment and assign users from allowed tenants.
Why it's wrong here
User assignment is for enterprise apps, not for restricting tenants in multi-tenant apps.
✗
Validate the 'iss' claim to ensure it matches one of your allowed tenant issuer URLs.
Why it's wrong here
While possible, using 'tid' is more reliable and recommended.
✗
Use Azure AD tenant restrictions to block all tenants except the allowed ones.
Why it's wrong here
Tenant restrictions are controlled by the tenant admin, not the app developer.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

TExam Day Tips
→Underline the problem statement mentally.
→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.
