The correct answer is sensitive information types (SITs). This is the Microsoft Purview feature designed specifically to define a custom pattern for sensitivity label detection, such as a regular expression matching the employee ID format EMP-12345. Once the SIT is created, it can be referenced directly in a sensitivity label’s auto-labeling policy to automatically classify and protect documents in SharePoint Online. On the MS-102 exam, this question tests your ability to distinguish between SITs and other Purview tools like trainable classifiers or retention labels—a common trap is confusing SITs with data loss prevention (DLP) rules, but remember that SITs are the pattern-defining building blocks used across compliance solutions. For a memory tip, think of SITs as the “regex engine” for labels: if you need to detect a specific string format, you always start with a sensitive information type.
MS-102 Manage compliance by using Microsoft Purview Practice Question
This MS-102 practice question tests your understanding of manage compliance by using microsoft purview. 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.
A compliance officer needs to automatically detect documents in SharePoint Online that contain a custom pattern (e.g., employee ID in the format EMP-12345). The pattern will be used to apply a sensitivity label. Which Microsoft Purview feature should the officer use to define the pattern?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sensitive information types
Sensitive information types (SITs) in Microsoft Purview are specifically designed to define custom patterns, such as regular expressions for employee IDs like EMP-12345. Once defined, these SITs can be used in sensitivity labels to automatically classify and protect documents in SharePoint Online. This is the correct feature because it directly supports pattern-based detection for labeling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Sensitive information types
Why this is correct
Custom sensitive information types can be created to define patterns like employee IDs, which can then be used for automatic labeling or DLP.
Related concept
Read the scenario before looking for a memorised answer.
✗
Data Loss Prevention (DLP) policies
Why it's wrong here
DLP policies use sensitive information types but do not define them; the pattern must be defined in sensitive info types first.
✗
Content search
Why it's wrong here
Content search is for querying existing content, not for defining patterns or automatic detection.
✗
Data classification reports
Why it's wrong here
Data classification reports show overview of classified data but do not allow definition of custom patterns.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DLP policies with pattern definition, but DLP policies only consume pre-defined sensitive information types and cannot create them.
Trap categories for this question
Command / output trap
Data classification reports show overview of classified data but do not allow definition of custom patterns.
Detailed technical explanation
How to think about this question
Custom sensitive information types are built using XML or PowerShell to define a primary pattern (e.g., regex for EMP-\d{5}) with optional proximity, confidence levels, and keyword lists. Under the hood, Purview uses the Microsoft 365 classification engine to scan content in SharePoint, OneDrive, and Exchange, matching the pattern against document text. In a real-world scenario, an organization might combine this with a sensitivity label that automatically applies encryption when the pattern is detected, ensuring compliance without manual intervention.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
