The correct answer is that external users will receive a one-time passcode via email when they are invited. This is true because the exhibit shows the `enableB2BEmailOneTimePasscode` setting is set to `true`, which means that if an invited guest cannot authenticate through their existing identity provider—such as a Microsoft, Google, or SAML/WS-Fed account—Azure AD will fall back to sending a one-time passcode to their email address for authentication. On the AZ-500 exam, this question tests your ability to interpret Azure AD external collaboration settings from a JSON or portal view, specifically distinguishing between the `allowInvitationsFrom`, `allowEmailVerifiedUsersToJoinOrganization`, and `enableB2BDirectConnect` properties. A common trap is confusing the one-time passcode feature with the ability for email-verified users to join automatically, which is controlled by a separate setting. Remember the mnemonic “OTP for guests, not for joiners” to keep the one-time passcode tied to invited users, not self-service sign-ups.
AZ-500 Secure identity and access Practice Question
This AZ-500 practice question tests your understanding of secure identity and access. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. You are reviewing the external collaboration settings for your Microsoft Entra ID tenant. Based on the exhibit, which of the following statements is true about the current configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
External users will receive a one-time passcode via email when they are invited.
Option C is correct because enableB2BEmailOneTimePasscode is true, allowing guests to authenticate using a one-time passcode if they cannot use other identity providers. Option A is wrong because allowInvitationsFrom is set to 'adminsAndGuestInviters', meaning guests can also invite. Option B is wrong because allowEmailVerifiedUsersToJoinOrganization is false, so email-verified users cannot join automatically. Option D is wrong because enableB2BDirectConnect is false, so Teams external access is not enabled.
Key principle: 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.
