Administering Information Security in Microsoft 365 SC-401 Practice Test 5
Question 40
An administrator needs to determine whether a classifier flags research reports for their meaning rather than for one standardized identifier. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- The detector definition appears in the policy list but no known-positive document was evaluated
- A sample file name includes the target term but the file contents were never classified
- Classified research reports and semantically different documents receive appropriately different scores
- Only one known-positive file was tried; no similarly formatted negative control was checked
Explanation
Correct Answer
C:Classified research reports and semantically different documents receive appropriately different scores. This observation verifies the required control: Compare trainable classification outputs with representative content and near-miss documents. Classifiers target document meaning; a pattern-only match would not assess semantic content categories.
Incorrect Answers
A:A saved detector does not establish that the intended sensitive sample is recognized. In the present case the decisive acceptance evidence is: Classified research reports and semantically different documents receive appropriately different scores
B:A filename clue does not verify sensitive information matching within document content. In the present case the decisive acceptance evidence is: Classified research reports and semantically different documents receive appropriately different scores
D:An isolated positive result cannot exclude the false positives the matching requirement must avoid. In the present case the decisive acceptance evidence is: Classified research reports and semantically different documents receive appropriately different scores
Question 41
A custom sensitive information type triggers on internal phone extension numbers with no other context. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Broaden the regex to accept every three-digit number
- Tune supporting evidence and confidence to require nearby personnel directory terms
- Increase the maximum file age in retention policies
- Disable content scanning in the relevant policy
Explanation
Correct Answer
B:Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:Broader matching makes extension-number collisions more likely. Consequently it cannot satisfy the stated requirement.
C:A retention setting does not influence sensitive information identification. Consequently it cannot satisfy the stated requirement.
D:Disabling scanning removes protection rather than improving identification accuracy. Consequently it cannot satisfy the stated requirement.
Question 42
A custom sensitive information type triggers on internal phone extension numbers with no other context. During the pilot, an administrator instead implements this approach: Broaden the regex to accept every three-digit number. The required outcome is not achieved. Which technical diagnosis BEST explains the failure?
- A retention setting does not influence sensitive information identification
- Disabling scanning removes protection rather than improving identification accuracy
- Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches
- Broader matching makes extension-number collisions more likely
Explanation
Correct Answer
D:Broader matching makes extension-number collisions more likely. This identifies the failure of the specific pilot implementation.
Incorrect Answers
A:A retention setting does not influence sensitive information identification. That limitation concerns a different competing approach, not this pilot change.
B:Disabling scanning removes protection rather than improving identification accuracy. This is a real constraint on a separate choice rather than the stated pilot implementation.
C:Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches. This describes the sound approach but does not diagnose why the observed alternative failed.
Question 43
A custom sensitive information type triggers on internal phone extension numbers with no other context. A change reviewer proposes Increase the maximum file age in retention policies instead of Tune supporting evidence and confidence to require nearby personnel directory terms. Which assessment BEST explains the proposed design gap?
- A retention setting does not influence sensitive information identification
- Broader matching makes extension-number collisions more likely
- Disabling scanning removes protection rather than improving identification accuracy
- Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches
Explanation
Correct Answer
A:A retention setting does not influence sensitive information identification. This deficiency directly applies to the suggested competing design.
Incorrect Answers
B:Broader matching makes extension-number collisions more likely. This limitation relates to a different rejected configuration.
C:Disabling scanning removes protection rather than improving identification accuracy. This explains a different option rather than the actual proposal.
D:Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches. This supports the preferred design rather than evaluating the proposed alternative.
Question 44
A custom sensitive information type triggers on internal phone extension numbers with no other context. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- The detector definition appears in the policy list but no known-positive document was evaluated
- A sample file name includes the target term but the file contents were never classified
- False matches drop for invoice amounts while directory sample extensions still match
- Only one known-positive file was tried; no similarly formatted negative control was checked
Explanation
Correct Answer
C:False matches drop for invoice amounts while directory sample extensions still match. This observation verifies the required control: Tune supporting evidence and confidence to require nearby personnel directory terms. Confidence tuning can suppress low-evidence matches while retaining intended confidential number matches.
Incorrect Answers
A:A saved detector does not establish that the intended sensitive sample is recognized. In the present case the decisive acceptance evidence is: False matches drop for invoice amounts while directory sample extensions still match
B:A filename clue does not verify sensitive information matching within document content. In the present case the decisive acceptance evidence is: False matches drop for invoice amounts while directory sample extensions still match
D:An isolated positive result cannot exclude the false positives the matching requirement must avoid. In the present case the decisive acceptance evidence is: False matches drop for invoice amounts while directory sample extensions still match
Question 45
A compliance analyst wants a tenant-wide summary of labeled files and sensitive-information type counts over time. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Use Microsoft Purview Data explorer and its classification reporting views
- Open an individual retained item in Content explorer to estimate every workload count
- Inspect one insider risk case to estimate all label usage
- Export only Entra group membership reports
Explanation
Correct Answer
A:Data explorer provides aggregated visibility into classified and labeled content. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
B:One document inspection cannot supply estate-wide aggregate metrics. Consequently it cannot satisfy the stated requirement.
C:An incident case covers scoped activity rather than the whole data classification inventory. Consequently it cannot satisfy the stated requirement.
D:Identity groups do not quantify sensitive data matches or label use. Consequently it cannot satisfy the stated requirement.

Question 48
A compliance analyst wants a tenant-wide summary of labeled files and sensitive-information type counts over time. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- The detector definition appears in the policy list but no known-positive document was evaluated
- The report breaks down sensitivity and SIT trends by workload without reading every document
- A sample file name includes the target term but the file contents were never classified
- Only one known-positive file was tried; no similarly formatted negative control was checked
Explanation

Question 49
A reviewer is authorized to inspect the particular SharePoint file behind a classification alert rather than just aggregate counts. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Use Data explorer totals alone to read the implicated document
- Rely only on the DLP alert count with no matching content sample
- Change the tenant-wide default sensitivity label
- Use Content explorer with the appropriate content-view permissions
Explanation
Correct Answer
D:Content explorer provides item-level drilldown subject to role-based access. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:Aggregate counts do not expose the individual content being investigated. Consequently it cannot satisfy the stated requirement.
B:Alert counts do not identify the precise file content that matched. Consequently it cannot satisfy the stated requirement.
C:Default labeling cannot reveal the original item that triggered classification. Consequently it cannot satisfy the stated requirement.
