Full question →mediummultiple choiceObjective-mapped
A security analyst has identified a new malware sample with a specific SHA256 hash. The analyst needs to immediately block this file from executing on any managed endpoint across the organization, including prevention of future execution. Which Microsoft Defender for Endpoint capability should the analyst use?
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
Distractor review
Attack surface reduction (ASR) rules
ASR rules block behaviors (e.g., macros, scripts) but not specific file hashes. They cannot be used to block a known malware hash.
B
Best answer
Indicators (IoCs) for file hashes
Indicators for file hashes with action 'Block and Remediate' block execution of the specific file across all endpoints and remove it if found.
C
Distractor review
Custom detection rules via advanced hunting
Custom detection rules create alerts when query conditions are met, but they do not block execution automatically. They are reactive, not preventive.
D
Distractor review
Microsoft Defender Vulnerability Management
Vulnerability management identifies weaknesses and misconfigurations but does not block specific file hashes from executing.
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: Indicators (IoCs) for file hashes — In Microsoft Defender for Endpoint, indicators of compromise (IoCs) allow administrators to define custom indicators for file hashes, IP addresses, URLs, and certificates. When a file hash indicator is configured with the action 'Block and Remediate', Defender will block execution of that file on all onboarded endpoints and automatically remediate (contain) it if detected. Attack surface reduction rules are for behavioral patterns, not specific hashes. Custom detections are for creating alerts based on advanced hunting queries, not for immediate file blocking.
