Quick Answer
The answer is to create a guest user in Azure AD. This is correct because Azure AD B2B collaboration is the foundational mechanism for granting external identities, like a vendor, access to SharePoint Online resources while maintaining full control over permissions and lifecycle. By inviting a guest user, the admin can assign specific SharePoint site permissions and later revoke access or apply conditional access policies, ensuring the vendor’s temporary access is both secure and auditable. On the MS-102 exam, this concept tests your understanding of identity governance versus direct site sharing—a common trap is choosing “external sharing settings” or “anonymous access links” instead, which lack identity tracking and granular revocation. Remember the memory tip: “Guest, not link” — a guest user provides a distinct Azure AD identity for auditing, while a sharing link does not.
This MS-102 practice question tests your understanding of manage users, groups, licensing, and support. 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.
An admin needs to provide a vendor with temporary access to a SharePoint site. What should the admin create?
Guest user in Azure AD
Allows external access with B2B collaboration.
Anonymous sharing link
Why wrong: Less secure and temporary.
Security group
Why wrong: Doesn't create external identity.
New user in your domain
Why wrong: Vendor is external.

Correct answer & explanation
Guest user in Azure AD
A is correct because creating a guest user in Azure AD is the proper method to grant external users access to SharePoint Online resources with controlled permissions. Guest users are invited via Azure AD B2B collaboration, which allows the admin to assign specific SharePoint site permissions while maintaining oversight and the ability to revoke access. This approach ensures the vendor has a distinct identity for auditing and conditional access policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse anonymous sharing links (which are easy to create) with proper external user management, overlooking the need for identity-based access control and auditability required for vendor access.
Detailed technical explanation
Azure AD B2B collaboration uses the Invitation API (Microsoft Graph) to send an email to the vendor, who then redeems the invitation using their existing Azure AD or Microsoft account (or creates a new one). The guest user object is stored in the tenant’s Azure AD with UserType set to 'Guest', and SharePoint Online evaluates access via the site’s external sharing settings, which must be enabled for guests. Conditional access policies, such as requiring multi-factor authentication, can be applied to guest users to enforce security for temporary access scenarios.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
