A controlled 4625 event is received in SecurityEvent while unselected categories remain absent The machine shows the expected DCR association and Windows events arrive in the targeted workspace The event appears in the intended SecurityEvent table with device identity and timestamp A controlled matching event creates both the detection alert and its recorded response action Explanation Correct Answer B:The machine shows the expected DCR association and Windows events arrive in the targeted workspace. Incorrect Answers A:A controlled 4625 event is received in SecurityEvent while unselected categories remain absent; the machine shows the expected DCR association and Windows events arrive in the targeted workspace. C:The event appears in the intended SecurityEvent table with device identity and timestamp; the machine shows the expected DCR association and Windows events arrive in the targeted workspace. D:A controlled matching event creates both the detection alert and its recorded response action; the machine shows the expected DCR association and Windows events arrive in the targeted workspace.
Question 285 A regional bank needs to investigate a source that has AMA installed but no SecurityEvent data. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Inspect DCR association and selected event streams before changing analytic rules Onboard supported machines with Azure Arc and AMA then associate the correct DCR Configure Windows Security Events via AMA with an associated data collection rule Inspect forwarder routing and AMA/DCR association to the workspace Explanation Correct Answer A:Agent installation alone does not determine which security events arrive. Incorrect Answers B:Hybrid machine eligibility and DCR association determine what the collector receives. C:AMA and DCR govern supported Windows Security event collection. D:Connectivity and DCR scope explain missing CEF ingestion before detection logic.
Question 286 The health network SOC needs to investigate a source that has AMA installed but no SecurityEvent data, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? XPath filtering selects the desired events before ingestion. Agent installation alone does not determine which security events arrive. CommonSecurityLog is for structured CEF security records, not arbitrary Syslog. Hybrid machine eligibility and DCR association determine what the collector receives. Explanation Correct Answer B:Agent installation alone does not determine which security events arrive. Incorrect Answers A:Limiting collected Windows event IDs to a security team's defined audit scope does not investigate a source that has AMA installed but no SecurityEvent data. C:Identifying why a device's generic Syslog messages are not appearing in CommonSecurityLog does not investigate a source that has AMA installed but no SecurityEvent data. D:Bringing events from selected on-prem Windows endpoints through Azure monitoring does not investigate a source that has AMA installed but no SecurityEvent data.
Question 287 AMA is installed on a Windows VM but SecurityEvent has no entries; its DCR is linked to a different workspace. Which explanation best accounts for the specific failure? The required Windows security event ID is missing from the DCR XPath expression The machine lacks correct Azure Arc onboarding or DCR association required for hybrid collection The detection query includes benign maintenance events that should be excluded with narrow source-aware predicates The agent's effective DCR destination points to another workspace instead of the Sentinel workspace Explanation Correct Answer D:The agent's effective DCR destination points to another workspace instead of the Sentinel workspace. Incorrect Answers A:The required Windows security event ID is missing from the DCR XPath expression; the agent's effective DCR destination points to another workspace instead of the Sentinel workspace. B:The machine lacks correct Azure Arc onboarding or DCR association required for hybrid collection; the agent's effective DCR destination points to another workspace instead of the Sentinel workspace. C:The detection query includes benign maintenance events that should be excluded with narrow source-aware predicates; the agent's effective DCR destination points to another workspace instead of the Sentinel workspace.
Question 288 During a controlled investigation, a VM with AMA and a valid Windows Security DCR generates a controlled security event. Which observation most directly verifies the intended technical behavior? A controlled 4625 event is received in SecurityEvent while unselected categories remain absent The machine shows the expected DCR association and Windows events arrive in the targeted workspace The event appears in the intended SecurityEvent table with device identity and timestamp It suppresses the authorized maintenance events while still alerting on the adversarial test pattern Explanation Correct Answer C:The event appears in the intended SecurityEvent table with device identity and timestamp. Incorrect Answers A:A controlled 4625 event is received in SecurityEvent while unselected categories remain absent; the event appears in the intended SecurityEvent table with device identity and timestamp. B:The machine shows the expected DCR association and Windows events arrive in the targeted workspace; the event appears in the intended SecurityEvent table with device identity and timestamp. D:It suppresses the authorized maintenance events while still alerting on the adversarial test pattern; the event appears in the intended SecurityEvent table with device identity and timestamp.

Evaluate Sentinel anomalies and eligible behavioral detections Create a Microsoft Defender XDR custom detection rule using the validated hunting query Include the required timestamp and event identifiers from the applicable table Refine the query predicate and scheduling to match the intended event population Explanation Correct Answer B:Custom detection rules convert query matches into alerts and permitted responses. Incorrect Answers A:Anomaly detection uses established behavior rather than only fixed event signatures. C:Rule eligibility depends on its data schema and reliable event attribution.
