Question 445 A utility operator needs to assess suspicious directory replication requests by unexpected principals. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Examine Defender for Identity directory replication alerts and principal permissions Investigate the Defender for Identity alert and its account/device entities Correlate Defender for Identity alerts with authentication and endpoint evidence Open the Defender for Cloud workload protection alert and related machine evidence Explanation Correct Answer A:Abnormal replication operations may indicate a high-risk identity attack. Incorrect Answers B:Defender for Identity analyzes Active Directory-related suspicious behaviors. C:Lateral movement requires cross-entity timeline analysis, not only a mailbox audit. D:Workload-protection alerts reveal affected cloud resources and relevant activities.
Question 446 The media company SOC needs to assess suspicious directory replication requests by unexpected principals, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? Lateral movement requires cross-entity timeline analysis, not only a mailbox audit. Abnormal replication operations may indicate a high-risk identity attack. Defender for Identity analyzes Active Directory-related suspicious behaviors. User-level compromise probability is distinct from the risk of one authentication. Explanation Correct Answer B:Abnormal replication operations may indicate a high-risk identity attack. Incorrect Answers A:Investigating alleged lateral movement using stolen identity credentials does not assess suspicious directory replication requests by unexpected principals. C:Detecting suspicious on-premises directory reconnaissance against domain controllers does not assess suspicious directory replication requests by unexpected principals. D:Distinguishing risky users from a single risky sign-in does not assess suspicious directory replication requests by unexpected principals.
Question 447 A replication-related identity alert is raised for an unexpected workstation account with no domain controller role. Which explanation best accounts for the specific failure? Port reachability alone cannot establish stolen-credential use across devices The alert was not compared with the service identity's authorized activity and entity history Message delivery records do not prove a Safe Links click by the recipient The suspected principal or host lacks an authorized directory replication role and the activity needs privileged verification Explanation Correct Answer D:The suspected principal or host lacks an authorized directory replication role and the activity needs privileged verification. Incorrect Answers A:Port reachability alone cannot establish stolen-credential use across devices; the suspected principal or host lacks an authorized directory replication role and the activity needs privileged verification. B:The alert was not compared with the service identity's authorized activity and entity history; the suspected principal or host lacks an authorized directory replication role and the activity needs privileged verification. C:Message delivery records do not prove a Safe Links click by the recipient; the suspected principal or host lacks an authorized directory replication role and the activity needs privileged verification.
Question 448 During a controlled investigation, a directory replication request is investigated in Defender for Identity. Which observation most directly verifies the intended technical behavior?
