The answer is Microsoft Entra B2B collaboration with external identities. This configuration is correct because it enables external partners to authenticate using their own corporate credentials—such as their existing Azure AD, Microsoft account, or other federated identity providers—without requiring you to manage separate passwords or local accounts in your tenant. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this scenario tests your understanding of identity governance for hybrid and multi-identity environments, often appearing as a distractor against options like configuring a custom SAML federation or creating guest user accounts manually. A common trap is assuming you need to set up a direct federation trust with each partner’s domain, but B2B collaboration handles this automatically through invitation and redemption flows. Memory tip: think “B2B = bring your own identity” to recall that partners use their own credentials, not yours.
AZ-305 Practice Question: Design identity, governance, and monitoring solutions
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your company has a Microsoft Entra ID tenant with 10,000 users. You plan to grant external partners access to a specific SharePoint Online site using Microsoft Entra B2B collaboration. You need to ensure that partners can authenticate using their own corporate credentials. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra B2B collaboration with external identities
Microsoft Entra B2B collaboration allows external partners to authenticate using their own corporate credentials (such as Azure AD, Microsoft account, or other identity providers) without requiring a separate password or local account. This is the correct solution because it directly supports the requirement for partners to use their own identity providers, enabling seamless access to the SharePoint Online site via guest user invitations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Cross-tenant synchronization
Why it's wrong here
This is for synchronizing users between tenants, not for authentication.
✗
Conditional Access policy for guest users
Why it's wrong here
Conditional Access controls access but does not enable external authentication.
✓
Microsoft Entra B2B collaboration with external identities
Why this is correct
B2B collaboration allows external users to authenticate with their own identity provider.

✗
Microsoft Entra guest user accounts with password
Why it's wrong here
Guest accounts require you to manage credentials, not the partner's own.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Cross-tenant synchronization (Option A) with B2B collaboration, but Cross-tenant synchronization is for internal multi-tenant scenarios, not for granting external partners access with their own credentials.
Detailed technical explanation
How to think about this question
Microsoft Entra B2B collaboration leverages SAML 2.0 or OpenID Connect to establish trust with the partner's identity provider, allowing token exchange without storing passwords. Under the hood, when a partner accepts an invitation, their home tenant issues a token that is validated by the resource tenant, enabling single sign-on (SSO) and reducing credential management overhead. In a real-world scenario, this is critical for organizations that need to comply with security policies requiring partners to use their own MFA and conditional access controls.

→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.
