A security team needs to investigate a potential data breach that may involve unauthorized access to sensitive files in SharePoint Online and OneDrive for Business. They want to search the unified audit log for file access events, including accesses from mobile devices and third-party applications. Additionally, they need to create custom alert policies that trigger when specific high-privilege users download large volumes of files in a short period. Which Microsoft Purview solution should they 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
Best answer
Microsoft Purview Audit (Premium)
Correct. Audit (Premium) offers custom alert policies, long retention, and detailed log access for activities across SharePoint, OneDrive, and third-party apps, enabling thorough incident investigations.
B
Distractor review
Microsoft Purview eDiscovery (Premium)
eDiscovery (Premium) is focused on legal hold, review sets, and advanced search for litigation or regulatory cases, not real-time alerting and custom log queries for investigations.
C
Distractor review
Microsoft Purview Data Lifecycle Management
Data Lifecycle Management automates retention and deletion policies but does not provide audit log search or custom alerting.
D
Distractor review
Microsoft Purview Communication Compliance
Communication Compliance monitors communications (email, Teams) for policy violations, not file access events or audit log queries.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
