Microsoft SC-401 Practice Test 4

Question 30

A rule unexpectedly fails to detect a known sample containing a real employee ID. Which response most directly addresses the stated need?

Run the sensitive information type's supported test workflow on representative files.
Validate the SIT with a known positive sample and inspect match details.
Refine primary patterns and corroborative evidence against test samples.
Document and review built-in and custom SIT definitions with assigned owners.

Explanation

Correct Answer

B:

A controlled positive test separates classifier configuration faults from missing data or unsupported context. It directly meets the case's requirement to diagnose a missed valid classifier match.

Incorrect Answers

A:

Testing classification against reference samples reveals whether detection logic matches the intended content. That would validate a new sensitive information type; the question instead requires a way to diagnose a missed valid classifier match.

C:

SIT detection depends on patterns, confidence, and proximity; samples expose false matches. That would tune overly broad invoice detection; the question instead requires a way to diagnose a missed valid classifier match.

D:

A governed classifier inventory supports traceability and maintenance of detection logic. That would maintain classifier governance evidence; the question instead requires a way to diagnose a missed valid classifier match.

Question 31

Before publishing a detector to production DLP, the analyst wants controlled evidence on the detector's behavior. Which configuration BEST meets the requirement?

Refine primary patterns and corroborative evidence against test samples.
Validate the SIT with a known positive sample and inspect match details.
Run the sensitive information type's supported test workflow on representative files.
Document and review built-in and custom SIT definitions with assigned owners.

Question 33

An organization must flag a proprietary contract number only when it appears alongside the word Restricted within 50 characters. Which action most directly satisfies this requirement?

Build a custom SIT with primary regex and proximity-constrained supporting term.
Prefer EDM matching against the approved client register.
Combine the relevant built-in SITs in the rule's condition logic.
Enable OCR support and use suitable SIT detection in supported locations.

Explanation

Correct Answer

A:

A correlated pattern and nearby word narrow the match to the intended context. It directly meets the case's requirement to detect identifiers with nearby evidence.

Incorrect Answers

B:

An exact data match reference distinguishes registered values from format-only lookalikes. That would restrict matches to actual clients; the question instead requires a way to detect identifiers with nearby evidence.

C:

Multiple SIT conditions can cover distinct standardized formats under the policy's configured logic. That would cover either regulated identifier type; the question instead requires a way to detect identifiers with nearby evidence.

D:

OCR contributes extracted text while SIT detection recognizes the resulting sensitive patterns. That would detect visual and typed sensitive identifiers; the question instead requires a way to detect identifiers with nearby evidence.

Question 34

Compliance must trigger when either of two established regulated ID formats appears, without creating a fused new syntax. What is the most appropriate next action?

Enable OCR support and use suitable SIT detection in supported locations.

Question 35

A privacy officer wants a rule to trigger only for known clients, even if an arbitrary test number matches the national ID pattern. Which response most directly addresses the stated need?

Enable OCR support and use suitable SIT detection in supported locations.

Prefer EDM matching against the approved client register.
Build a custom SIT with primary regex and proximity-constrained supporting term.

Question 37

A legal-review team needs to distinguish high-confidence exact cases from low-confidence contextual hints using one detector. Which Microsoft Purview approach should the administrator choose?

Define multiple confidence levels with appropriate evidence requirements.
Create carefully scoped custom patterns for each documented regional format.
Use a test DLP policy or simulation with the custom SIT.
Inspect matched evidence and configured proximity and confidence settings.

Explanation

Correct Answer

A:

SIT confidence levels can encode different degrees of corroboration. It directly meets the case's requirement to grade match certainty.

Incorrect Answers

B:
