Full question →mediummultiple choiceObjective-mapped
A company is experiencing a significant number of phishing attempts that target high-level executives by impersonating their email addresses. The security team wants to configure protection against user impersonation in Microsoft Defender for Office 365. Which setting must be enabled in the anti-phishing policy to protect these specific users?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Enable users to protect against impersonation
This setting allows you to define a list of specific users (e.g., executives) whose email addresses are protected from being impersonated in inbound emails. When impersonation is detected, the action defined in the policy is applied.
B
Distractor review
Enable domains to protect against impersonation
This setting protects against impersonation of entire domains (e.g., contoso.com) but does not protect specific individual email addresses. It would not directly address user impersonation.
C
Distractor review
Mailbox intelligence
Mailbox intelligence uses machine learning to identify normal email patterns and detect anomalous behavior, such as compromised accounts sending unusual emails. It does not prevent impersonation of specific users.
D
Distractor review
Spoofed sender posture
Spoofed sender posture is part of the spoof intelligence feature that evaluates email senders based on SPF, DKIM, and DMARC authentication. It is not designed to protect against user impersonation attacks.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A company recently added the custom domain 'contoso.com' to their Microsoft 365 tenant. Users report that they cannot receive external email sent to their new domain addresses. The administrator confirmed that the domain status shows 'Active' in the Microsoft 365 admin center. What is the most likely cause of this issue?
Question 2
A company has 500 users across Sales, Marketing, and IT departments. User objects are synced from on-premises Active Directory to Microsoft Entra ID using Azure AD Connect. Each department requires different Microsoft 365 license plans (e.g., Sales needs E3, Marketing needs Business Premium, IT needs E5). The administrator wants to automatically assign the appropriate license based on the department attribute without manual intervention. Which approach should the administrator use?
Question 3
A company has purchased 1000 Microsoft 365 E5 licenses and wants to automatically assign licenses to users based on their department attribute, which is synchronized from on-premises Active Directory. The department attribute is stored in Azure AD. Which automated method should the administrator use to achieve this?
Question 4
A company has just purchased Microsoft 365 Business Standard and added the custom domain 'fabrikam.com' to the tenant. They want to verify domain ownership. Which DNS record type must they add to their DNS provider?
Question 5
A company plans to migrate their email from an on-premises Exchange server to Exchange Online. They want to ensure that during the migration, mail sent to users who have already been migrated is delivered to Exchange Online, while mail for non-migrated users is delivered to on-premises. Which type of domain configuration should they use?
Question 6
A company has registered the custom domain 'contoso.com' and wants to host email for the subdomain 'sales.contoso.com' in Exchange Online. They have already verified the root domain. What additional step is required?
FAQ
Questions learners often ask
What does this MS-102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Enable users to protect against impersonation — To protect against user impersonation attacks, the anti-phishing policy must have 'Enable users to protect against impersonation' turned on, and the specific users (e.g., executives) must be added to the list of protected users. The 'Enable domains to protect against impersonation' option protects against domain impersonation, not individual users. Mailbox intelligence uses machine learning to detect unusual email behavior but does not directly protect specific users from impersonation. Spoofed sender posture handles email spoofing validation via SPF/DKIM/DMARC, not user impersonation.
