Microsoft SC-401 Practice Test 1

Question 1

A bank wants to find standard payment-card numbers in email and documents without inventing its own detector. Which configuration BEST meets the requirement?

  1. Select the built-in credit card number sensitive information type.
  2. Create a custom sensitive information type with a pattern and supporting evidence.
  3. Create a document fingerprint sensitive information type from the standard form.
  4. Configure an exact data match sensitive information type from an authorized source table.

Explanation

Correct Answer

A:

Microsoft's built-in sensitive information type evaluates card-number patterns with its defined supporting evidence. It directly meets the case's requirement to detect standard card-number formats.

Incorrect Answers

B:

Custom SIT patterns and corroborating keywords recognize organization-specific text formats. That would detect proprietary claim references; the question instead requires a way to detect standard card-number formats.

C:

Document fingerprinting detects documents resembling an approved text template, including configured partial matches. That would detect templated engagement letters; the question instead requires a way to detect standard card-number formats.

D:

EDM checks one-way-hashed source data values rather than accepting every syntactically matching number. That would match only registered personnel values; the question instead requires a way to detect standard card-number formats.

Question 2

An insurer has a proprietary claims reference with a fixed prefix and nearby case-management keywords, not a standard identifier. Which Microsoft Purview approach should the administrator choose?

  1. Create a document fingerprint sensitive information type from the standard form.
  2. Create a custom sensitive information type with a pattern and supporting evidence.
  3. Select the built-in credit card number sensitive information type.
  4. Configure an exact data match sensitive information type from an authorized source table.

Explanation

  2. Create a document fingerprint sensitive information type from the standard form.
  3. Configure an exact data match sensitive information type from an authorized source table.
  4. Create a custom sensitive information type with a pattern and supporting evidence.

A law firm must detect contract files that follow an uploaded standard engagement-letter template despite changing client names. What is the most appropriate next action?

  1. Create a custom sensitive information type with a pattern and supporting evidence.
  2. Configure an exact data match sensitive information type from an authorized source table.
  3. Select the built-in credit card number sensitive information type.
  4. Create a document fingerprint sensitive information type from the standard form.

Question 5

A false-positive investigation finds a custom ID detector fires on seven-digit strings without the surrounding business term. Which response most directly addresses the stated need?

  1. Require a supporting keyword within the custom SIT proximity window.
  2. Use a higher confidence match level in the DLP condition.
  3. Use a lower confidence match requirement for the SIT rule.
  4. Include a checksum-aware pattern or supported validating function in the custom SIT.

Explanation

Correct Answer

A:

Supporting evidence and proximity can distinguish relevant identifiers from unrelated numeric strings. It directly meets the case's requirement to reduce context-free numeric matches.

Incorrect Answers

B:

Higher confidence depends on stronger supporting evidence and typically reduces weak detections. That would require corroborated high-confidence matches; the question instead requires a way to reduce context-free numeric matches.

C:

Lower confidence matching can detect items with less supporting evidence and may increase false positives. That would favor recall when context is missing; the question instead requires a way to reduce context-free numeric matches.

D:

A validated primary pattern rejects values that match the shape but fail the check. That would validate a structured code; the question instead requires a way to reduce context-free numeric matches.

Question 6

A medical-record code is valid only if it matches a specific regex and satisfies a check digit calculation. Which configuration BEST meets the requirement?

  1. Require a supporting keyword within the custom SIT proximity window.
  2. Include a checksum-aware pattern or supported validating function in the custom SIT.
  3. Use a lower confidence match requirement for the SIT rule.
  4. Use a higher confidence match level in the DLP condition.

Explanation

Correct Answer

B:

A validated primary pattern rejects values that match the shape but fail the check. It directly meets the case's requirement to validate a structured code.

Incorrect Answers

A:

Supporting evidence and proximity can distinguish relevant identifiers from unrelated numeric strings. That would reduce context-free numeric matches; the question instead requires a way to validate a structured code.

C:

Lower confidence matching can detect items with less supporting evidence and may increase false positives. That would favor recall when context is missing; the question instead requires a way to validate a structured code.

D:

Higher confidence depends on stronger supporting evidence and typically reduces weak detections. That would require corroborated high-confidence matches; the question instead requires a way to validate a structured code.

Question 7

An analyst needs to catch genuine identifiers even when supporting terms are often omitted, accepting more noisy matches. Which Microsoft Purview approach should the administrator choose?

  1. Include a checksum-aware pattern or supported validating function in the custom SIT.
  2. Require a supporting keyword within the custom SIT proximity window.
  3. Use a lower confidence match requirement for the SIT rule.
  4. Use a higher confidence match level in the DLP condition.

Explanation

  1. Include a checksum-aware pattern or supported validating function in the custom SIT.
  2. Use a lower confidence match requirement for the SIT rule.
  3. Require a supporting keyword within the custom SIT proximity window.
  4. Use a higher confidence match level in the DLP condition.

Question 9

The fraud team has many labeled examples of harassment complaints that have no stable pattern of digits or keywords. What is the most appropriate next action?

  1. Train a custom trainable classifier with representative positive and negative samples.
  2. Define a keyword dictionary for classification.
  3. Evaluate an available built-in trainable classifier for the document category.
  4. Evaluate a Microsoft-provided built-in sensitive information type.

Explanation

Correct Answer

A:

A trainable classifier learns content characteristics from examples where deterministic expressions are inadequate. It directly meets the case's requirement to recognize example-based complaint language.

Incorrect Answers

B:

A keyword dictionary centrally maintains many exact terms used as supporting evidence or patterns. That would maintain a term-list detector; the question instead requires a way to recognize example-based complaint language.

C:

Built-in trainable classifiers identify semantic document types without a custom training project when suitable. That would classify document type by learned content; the question instead requires a way to recognize example-based complaint language.

D:

A predefined SIT captures an established identifier without requiring new supervised examples. That would classify common identification numbers; the question instead requires a way to recognize example-based complaint language.

Question 10

The organization needs a fast initial detector for commonly recognized national identification numbers. Which response most directly addresses the stated need?

  1. Evaluate an available built-in trainable classifier for the document category.
  2. Evaluate a Microsoft-provided built-in sensitive information type.
  3. Train a custom trainable classifier with representative positive and negative samples.
  4. Define a keyword dictionary for classification.

Explanation
