Full question →hardmultiple choiceObjective-mapped
A security analyst wants to create a custom detection rule that triggers when a device communicates with a new, unclassified IP address that has been flagged by Microsoft threat intelligence as potentially malicious. The rule should run every hour and create an incident if more than 5 such communications from the same device occur within a 24-hour window. Which advanced hunting tables should be joined in the KQL query for this rule?
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
DeviceNetworkEvents and IPReputation
DeviceNetworkEvents records network connections including remote IPs. IPReputation provides Microsoft's threat intelligence score for IP addresses, allowing the rule to filter for connections to flagged IPs. These tables can be joined on the RemoteIP column.
B
Distractor review
DeviceProcessEvents and AlertInfo
DeviceProcessEvents contains process creation events, not network connections. AlertInfo contains alert metadata, not IP reputation data. This pair does not provide the required network connection or threat intelligence data.
C
Distractor review
DeviceFileEvents and DeviceIPInfo
DeviceFileEvents tracks file operations, not network connections. DeviceIPInfo is not a standard advanced hunting table; the correct table for IP reputation is IPReputation. This pair is irrelevant for detecting network communications.
D
Distractor review
EmailEvents and DeviceNetworkEvents
EmailEvents covers email delivery, not network connections. While DeviceNetworkEvents is correct, joining it with EmailEvents does not provide threat intelligence on the IP. The rule would not know if the IP is flagged as malicious.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: DeviceNetworkEvents and IPReputation — To detect network connections to potentially malicious IPs, you need DeviceNetworkEvents for network connection data and IPReputation from the threat intelligence to evaluate if the IP is flagged. The rule can then aggregate by device and time to trigger based on the count threshold.
