Question 143 An operator sees a Sentinel playbook but cannot run it from the incident; its Logic App lacks appropriate run authorization. Which explanation best accounts for the specific failure? The operator or Sentinel service is missing the required Playbook Operator or Logic Apps execution permissions Reader grants observation, not the incident-management write rights of Responder The analyst requires Sentinel Contributor or an appropriately scoped rule-authoring role, not only Responder The KQL lacks selective time and entity predicates and scans too broadly Explanation Correct Answer A:The operator or Sentinel service is missing the required Playbook Operator or Logic Apps execution permissions. Incorrect Answers B:Reader grants observation, not the incident-management write rights of Responder; the operator or Sentinel service is missing the required Playbook Operator or Logic Apps execution permissions. C:The analyst requires Sentinel Contributor or an appropriately scoped rule-authoring role, not only Responder; the operator or Sentinel service is missing the required Playbook Operator or Logic Apps execution permissions. D:The KQL lacks selective time and entity predicates and scans too broadly; the operator or Sentinel service is missing the required Playbook Operator or Logic Apps execution permissions.
Question 144 During a controlled investigation, a limited incident responder runs an existing authorized Logic Apps playbook without editing its definition. Which observation most directly verifies the intended technical behavior? The incident ownership or status change succeeds while analytics rule editing remains unavailable The rule's saved query and configuration show the change, with access constrained to the assigned scope Its execution uses the intended bounded event set and returns the same supported detection signals with reduced scanned data The playbook run succeeds while its designer/editor permission is not granted Explanation Correct Answer D:The playbook run succeeds while its designer/editor permission is not granted. Incorrect Answers A:The incident ownership or status change succeeds while analytics rule editing remains unavailable; the playbook run succeeds while its designer/editor permission is not granted. B:The rule's saved query and configuration show the change, with access constrained to the assigned scope; the playbook run succeeds while its designer/editor permission is not granted. C:Its execution uses the intended bounded event set and returns the same supported detection signals with reduced scanned data; the playbook run succeeds while its designer/editor permission is not granted.
Question 145 A telecom provider needs to lower unnecessary data volume from a noisy collection source without silencing all detections. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Scope time filters and projected columns in the detection KQL before increasing resources Check the table's Analytics retention and data lake availability instead of assuming no ingestion Adjust supported data-collection filtering or transformation after assessing required fields Examine SOC optimization insights and recommended actions Explanation Correct Answer C:Source-selective filtering reduces ingestion while preserving needed records. Incorrect Answers A:Query optimization reduces work while retaining detection semantics. B:Query visibility depends on tier and retention settings as well as data presence. D:SOC optimization helps prioritize configuration improvements from observed telemetry.
Question 146 The regional bank SOC needs to lower unnecessary data volume from a noisy collection source without silencing all detections, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? Different retrieval requirements justify different data tiers. Reader can inspect information without incident-management write privileges. SOC optimization helps prioritize configuration improvements from observed telemetry. Source-selective filtering reduces ingestion while preserving needed records. Explanation Correct Answer D:Source-selective filtering reduces ingestion while preserving needed records. Incorrect Answers A:Deciding whether a low-frequency historical dataset needs to remain in expensive hot storage does not lower unnecessary data volume from a noisy collection source without silencing all detections. B:Allowing a junior analyst to review Sentinel incidents and data without editing incidents does not lower unnecessary data volume from a noisy collection source without silencing all detections. C:Finding underused security coverage improvements based on deployed Sentinel data does not lower unnecessary data volume from a noisy collection source without silencing all detections.
Question 147 After filtering a firewall connector, a serious blocked-egress event no longer reaches Sentinel. What must the team investigate before celebrating the lower ingestion bill? Whether a Defender for Office mail policy marks the email as Junk Whether the workbook dashboard font is unchanged Whether the data collection or transformation filter mistakenly drops the required event category or fields Whether an endpoint device tag is spelled consistently Explanation Correct Answer C:Cost-saving ingestion filters can accidentally discard security signals if important categories or fields are excluded. Incorrect Answers A:Mail delivery filtering does not affect the firewall collection stream. B:Dashboard styling does not determine ingestion content. D:An endpoint tag does not control filtering of the network appliance events.
Question 148 A firewall produces 60,000 low-value events per minute. After a supported DCR filtering change, which comparison most directly proves that unnecessary ingestion was reduced without removing required threat events? The firewall appliance continues producing the same local event count The Sentinel dashboard uses fewer visualization tiles Ingestion volume for the target stream decreases while sampled required security event types remain present downstream An unrelated endpoint begins sending Windows Security events Explanation Correct Answer C:A before-and-after stream-volume comparison plus preserved required event samples tests both efficiency and retained signal coverage. Incorrect Answers A:Unchanged local production does not show what a DCR allowed into the workspace. B:Visualization count does not measure ingested event volume or required fields. D:Another connector’s activity is unrelated to the noisy firewall stream.
Question 149 A manufacturer needs to find underused security coverage improvements based on deployed Sentinel data. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement?
