Question 769 of 975

Deploy and manage a Microsoft 365 tenant →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is to use advanced hunting in the Microsoft 365 Defender portal first. This is correct because advanced hunting allows you to query raw, cross-workload telemetry—spanning Identity, Exchange Online, SharePoint Online, and Defender for Cloud Apps—using a single Kusto Query Language (KQL) query, enabling you to correlate sign-ins, file downloads, and app sessions from the compromised user in one view. On the MS-102 exam, this scenario tests your understanding that advanced hunting is the primary tool for investigating compromised credentials across Microsoft 365 services, as it provides the unified telemetry needed to scope a breach without jumping between separate portals. A common trap is to start with a specific workload report (like SharePoint access logs) or a sign-in log, which misses cross-service correlation. Memory tip: think of advanced hunting as the “single pane of glass” for forensic investigation—if you need to connect events across Identity, Email, and Cloud Apps, start here.

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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 are the Microsoft 365 administrator for a multinational company. The company has deployed Microsoft Defender for Office 365 and Microsoft Defender for Cloud Apps. Recently, the security team detected that a user's credentials were compromised and used to access SharePoint Online from an unusual location. You need to investigate the incident and determine the full scope of the breach. The solution must use Microsoft 365 Defender to correlate events. What should you do first?

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
Use the Microsoft Purview compliance portal to search for the user's activity in audit logs.
Why wrong: Audit logs are useful but not as effective for threat investigation across multiple workloads.
B
Use advanced hunting in Microsoft 365 Defender portal to query for events related to the user across workloads.
Advanced hunting allows correlation of events from Defender for Office 365, Defender for Cloud Apps, and Microsoft Entra ID.
C
Use Microsoft Defender for Cloud Apps to investigate the user's activity log.
Why wrong: This only covers cloud app activities, not email or identity events.
D
Use Microsoft Sentinel to query the user's events from the workspace.
Why wrong: Sentinel requires additional setup and licensing; the first step should use integrated tools in Defender XDR.

Correct answer & explanation

✓

Use advanced hunting in Microsoft 365 Defender portal to query for events related to the user across workloads.

Option B is correct because advanced hunting in the Microsoft 365 Defender portal allows you to query raw, cross-workload telemetry (e.g., from Identity, Exchange Online, SharePoint Online, and Defender for Cloud Apps) in a single Kusto Query Language (KQL) query. This is the most efficient first step to correlate events such as sign-ins, mailbox access, file downloads, and app sessions related to the compromised user, enabling you to determine the full scope of the breach across all Microsoft 365 services.

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 default to the audit log (Option A) because it is familiar from compliance scenarios, but the question explicitly requires correlation across workloads using Microsoft 365 Defender, which is only possible with advanced hunting's cross-table queries.

Detailed technical explanation

How to think about this question

Advanced hunting in Microsoft 365 Defender exposes tables such as IdentityLogonEvents, CloudAppEvents, EmailEvents, and FileEvents, which can be joined on user principal names or session IDs to trace a compromised user's activity across identity, email, cloud apps, and SharePoint. Under the hood, these tables are populated by the Microsoft 365 Defender sensor pipeline, which normalizes telemetry from multiple sources into a unified schema, allowing you to pivot from a single sign-in anomaly to related file access or mailbox rules in one query. In a real-world scenario, an administrator might use a KQL query like `IdentityLogonEvents | where AccountUpn == 'user@contoso.com' | join CloudAppEvents on AccountUpn` to quickly map the blast radius.

TExam Day Tips

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.
