- A
Add the partner tenant ID to the AllowedTenants list in the tenant restrictions policy.
Adding the partner tenant ID to the AllowedTenants list allows users from that tenant to access resources without being blocked.
- B
Create a Conditional Access policy to exclude partner users from tenant restriction evaluation.
Why wrong: Conditional Access policies do not affect the tenant restriction header check.
- C
Configure Azure AD B2B collaboration and invite partner users as guests.
Why wrong: B2B collaboration does not bypass tenant restrictions; the header is still evaluated.
- D
Configure cross-tenant access settings in Microsoft Entra ID to allow partner tenant.
Why wrong: Cross-tenant access settings control inbound/outbound trust, not tenant restriction header evaluation.
Quick Answer
The answer is to add the partner tenant ID to the AllowedTenants list in the tenant restrictions policy. This is correct because tenant restrictions in Microsoft Entra ID enforce data exfiltration controls by inspecting the X-MS-Cloud-Extension header, and only tenants explicitly listed in the AllowedTenants list are permitted through the restriction. On the MS-102 exam, this question tests your ability to distinguish between tenant restrictions and other access controls like Azure AD B2B or cross-tenant access settings, which are common distractors. A key trap is assuming that inviting a partner via B2B or configuring cross-tenant access alone bypasses the restriction, but tenant restrictions operate at the network header level and require direct tenant ID inclusion. For a memory tip, think "AllowedTenants = bypass header check" — if the partner’s tenant ID isn’t on that list, the header blocks them regardless of other settings.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Add the partner tenant ID to the AllowedTenants list in the tenant restrictions policy.
Tenant restrictions use the X-MS-Cloud-Extension header to allow or block access. To allow partner users, you need to add their tenant ID to the 'AllowedTenants' list in the tenant restrictions policy. Option D is the correct approach. Option A (Azure AD B2B) is about inviting external users but does not bypass tenant restrictions. Option B (cross-tenant access settings) is for inbound/outbound access but not for tenant restrictions. Option C (Conditional Access) can be used to control access but does not override tenant restrictions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
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.
