The answer is to enable 'Email one-time passcode for guests' and set 'Allow invitations to be sent to any user' to Yes. This configuration works because the email one-time passcode (OTP) authentication flow allows guest users to verify their identity via a code sent to their email, bypassing the need to click an acceptance link and enabling direct resource access without accepting an invitation. On the MS-102 exam, this scenario tests your understanding of Microsoft Entra ID external identity settings, often appearing in questions about guest user provisioning or collaboration policies. A common trap is confusing this with B2B direct connect or federation settings, which require interactive acceptance. Remember the key distinction: OTP eliminates the acceptance step entirely, while other methods still demand a redemption click. Memory tip: think "OTP = One Tap Passcode" — the guest gets the code and is in, no invitation click required.
MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. 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.
You need to ensure that guest users who are invited to your Microsoft Entra ID tenant can access resources without needing to accept an invitation. 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
✓
Enable 'Email one-time passcode for guests' and set 'Allow invitations to be sent to any user' to Yes.
Option D is correct because enabling 'Email one-time passcode for guests' and setting 'Allow invitations to be sent to any user' to Yes allows guest users to redeem an invitation without needing to accept it interactively. This configuration leverages the email one-time passcode (OTP) authentication flow, which bypasses the need for the guest to click an acceptance link, enabling direct resource access after the OTP is verified.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse settings that control who can invite guests (Options B and C) with settings that control the guest acceptance process, leading them to overlook the email one-time passcode feature that directly addresses the requirement to bypass acceptance.
Detailed technical explanation
How to think about this question
The email one-time passcode feature uses a redemption flow where the guest receives a one-time code via email instead of requiring them to click an acceptance link. This is particularly useful for guests without a Microsoft work or school account or a Microsoft account (MSA), as it allows them to authenticate using the OTP and directly access resources. Under the hood, the guest user object is created in the tenant with an invitation redemption status of 'PendingAcceptance' until the OTP is verified, at which point the status changes to 'Accepted' without an explicit invitation acceptance step.

→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.
