TI rules correlate observed indicators against intelligence data. Explanation Correct Answer A:Scheduled rules query data over configured execution windows. Incorrect Answers B:Validating a proposed new rule against realistic attacker behavior rather than a keyword match does not run a KQL rule on a configurable interval and lookback schedule. C:Identifying immediately arriving high-value events with near-real-time evaluation where supported does not run a KQL rule on a configurable interval and lookback schedule. D:Detecting matches to known threat indicators with relevant telemetry does not run a KQL rule on a configurable interval and lookback schedule.
Question 323 A scheduled Sentinel rule runs every five minutes but looks back only two minutes. Events arrive three minutes after they are generated and are frequently missed. What should be changed? Disable ingestion for delayed log sources Use an eDiscovery hold to retain the missing rule executions Increase the rule’s lookback window to cover supported ingestion latency and the intended evaluation interval Lower the workbook visualizer opacity Explanation Correct Answer C:The rule’s query window must encompass eligible records as they become available, with an appropriate interval/lookback relationship. Incorrect Answers A:Stopping a delayed source cannot recover missing detection coverage. B:eDiscovery content holds do not affect Sentinel scheduled query execution. D:Workbook appearance does not address query time-window gaps.
Question 324 A scheduled Sentinel analytics rule is configured to run every 10 minutes and look back 30 minutes. A test alert fires. Which observation validates the timing settings rather than merely the presence of a rule? A Microsoft Defender endpoint alert exists with no Sentinel analytic rule reference A DCR is collecting logs at the expected ingestion volume A threat-intelligence feed is refreshing indicators once per day The analytic-rule configuration shows the 10-minute frequency and 30-minute lookup window used for the resulting query Explanation Correct Answer D:The scheduled query rule’s frequency and lookup window specify when and how far back its detection KQL searches. Incorrect Answers A:A different product alert does not establish the Sentinel rule scheduling parameters. B:Data collection volume is independent of the analytic rule’s run cadence. C:Threat-feed refresh is unrelated to the analytic rule’s execution and lookback settings.
Question 325 A telecom provider needs to identify immediately arriving high-value events with near-real-time evaluation where supported. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Map the high-level tactic separately from the concrete ATT&CK technique Choose an appropriate near-real-time Sentinel analytics rule Use a supported threat intelligence analytics rule or indicator-matching detection Create a scheduled Sentinel analytics rule for the validated KQL detection Explanation Correct Answer B:NRT rules evaluate on a shorter defined cadence than many scheduled queries. Incorrect Answers A:A tactic describes why while a technique describes how the adversary acts. C:TI rules correlate observed indicators against intelligence data. D:Scheduled rules query data over configured execution windows.
Question 326 The regional bank SOC needs to identify immediately arriving high-value events with near-real-time evaluation where supported, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? Behavioral correlation can combine distinct signals rather than a single static equality predicate. TI rules correlate observed indicators against intelligence data. Query precision reduces unhelpful alerts without suppressing the entire security product. NRT rules evaluate on a shorter defined cadence than many scheduled queries. Explanation Correct Answer D:NRT rules evaluate on a shorter defined cadence than many scheduled queries. Incorrect Answers A:Combining suspicious cross-signal evidence where supported by a platform machine-learning detector does not identify immediately arriving high-value events with near-real-time evaluation where supported. B:Detecting matches to known threat indicators with relevant telemetry does not identify immediately arriving high-value events with near-real-time evaluation where supported. C:Avoiding repeated alerts from a poorly scoped broad detection query does not identify immediately arriving high-value events with near-real-time evaluation where supported.
Question 327 A near-real-time alert was expected shortly after an event but the team configured a standard scheduled rule with an hourly cadence. Which explanation best accounts for the specific failure? The detection lacks the actual threat-indicator matching logic or correct source correlation A supported multi-signal machine-learning detector requires corroborating evidence; one weak event cannot guarantee fusion The selected analytics rule type or run frequency does not provide the intended near-real-time evaluation UEBA context and corroborating behavior were not examined; anomaly alone is not a confirmed incident Explanation Correct Answer C:The selected analytics rule type or run frequency does not provide the intended near-real-time evaluation. Incorrect Answers A:The detection lacks the actual threat-indicator matching logic or correct source correlation; the selected analytics rule type or run frequency does not provide the intended near-real-time evaluation. B:A supported multi-signal machine-learning detector requires corroborating evidence; one weak event cannot guarantee fusion; the selected analytics rule type or run frequency does not provide the intended near-real-time evaluation. D:UEBA context and corroborating behavior were not examined; anomaly alone is not a confirmed incident; the selected analytics rule type or run frequency does not provide the intended near-real-time evaluation.
Question 328 During a controlled investigation, a supported high-priority event is delivered to the Sentinel Analytics data source. Which observation most directly verifies the intended technical behavior? The indicator-matching analytic produces an alert carrying the matching observed IP and indicator context A supported fusion/correlated incident groups relevant cross-signal evidence rather than creating it from one unrelated record The configured near-real-time rule generates the expected alert at its supported evaluation cadence The analyst sees entity behavior baseline, deviations and correlated security events supporting or refuting the suspicion Explanation Correct Answer C:The configured near-real-time rule generates the expected alert at its supported evaluation cadence. Incorrect Answers A:The indicator-matching analytic produces an alert carrying the matching observed IP and indicator context; the configured near-real-time rule generates the expected alert at its supported evaluation cadence. B:A supported fusion/correlated incident groups relevant cross-signal evidence rather than creating it from one unrelated record; the configured near-real-time rule generates the expected alert at its supported evaluation cadence. D:The analyst sees entity behavior baseline, deviations and correlated security events supporting or refuting the suspicion; the configured near-real-time rule generates the expected alert at its supported evaluation cadence.
