SC-400 Data Classification 2 — Questions and Answers
Question 1: A compliance administrator needs to identify all documents containing Social Security Numbers across SharePoint Online. Which Microsoft 365 feature should they use to scan and classify this content automatically?
- Sensitivity labels
- Trainable classifiers
- Sensitive information types (Correct answer)
- Retention labels
Correct answer: Sensitive information types
Sensitive information types use pattern matching and keyword detection to automatically identify specific data like SSNs across Microsoft 365 services.
Question 2: Which confidence level in a sensitive information type definition indicates the highest certainty that the detected content matches the pattern?
- Low confidence (65)
- Medium confidence (75)
- High confidence (85) (Correct answer)
- Confirmed match (95)
Correct answer: High confidence (85)
High confidence (85) in Microsoft's sensitive information types indicates the strongest pattern match with supporting evidence elements present.
Question 3: An organization wants to classify documents based on their content after they are created, without requiring user intervention. Which classification method achieves this?
- Manual labeling by users
- Automatic labeling using auto-labeling policies (Correct answer)
- Recommended labeling prompts
- Default label assignment
Correct answer: Automatic labeling using auto-labeling policies
Auto-labeling policies scan content in SharePoint, OneDrive, and Exchange and apply sensitivity labels automatically based on detected sensitive information types.
Question 4: What is the primary difference between a 'keyword dictionary' and a 'keyword list' in a custom sensitive information type?
- Keyword dictionaries support regex while keyword lists do not
- Keyword dictionaries can contain thousands of terms stored separately, while keyword lists are embedded inline (Correct answer)
- Keyword lists are case-sensitive while keyword dictionaries are not
- Keyword dictionaries require exact matches while keyword lists support wildcards
Correct answer: Keyword dictionaries can contain thousands of terms stored separately, while keyword lists are embedded inline
Keyword dictionaries store large term lists as separate uploadable files, whereas keyword lists are defined inline within the sensitive information type XML and are limited in size.
Question 5: A company needs to classify content that doesn't match predefined patterns but follows conceptual themes like 'project proposals.' Which classifier type is most appropriate?
- Sensitive information types
- Exact data match classifiers
- Trainable classifiers (Correct answer)
- Regular expression classifiers
Correct answer: Trainable classifiers
Trainable classifiers use machine learning trained on sample content to identify documents by concept or theme rather than specific patterns.
Question 6: When configuring an Exact Data Match (EDM) sensitive information type, what is the maximum number of rows supported in the data store?
- 1 million rows
- 5 million rows
- 100 million rows
- 10 million rows (Correct answer)
Correct answer: 10 million rows
EDM sensitive information types support up to 10 million rows of data in the uploaded data store for exact matching.

- Global Reader
- Compliance Data Administrator (Correct answer)
- Security Reader
- Message Center Reader
