Question 530 The software firm SOC needs to validate whether the same suspicious hash appears on multiple devices, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? Signature details help interpretation but do not guarantee benign behavior. Pending approval is a workflow state, not absence of an investigation. Process identity fields provide attribution context subject to logged evidence. Hash matching connects related artifacts across endpoints subject to coverage. Explanation Correct Answer D:Hash matching connects related artifacts across endpoints subject to coverage. Incorrect Answers A:Determining whether an executable has a known trusted publisher signature does not validate whether the same suspicious hash appears on multiple devices. B:Reviewing which defender remediation action is still waiting for approval does not validate whether the same suspicious hash appears on multiple devices. C:Determining which user context was active when a suspicious process ran does not validate whether the same suspicious hash appears on multiple devices.
Question 531 Two machines store executables with the same file name, but analysts have not compared their hashes. Why is it premature to assert they are the same malicious file? Every file with the same name has identical executable bytes The two machines share the same Defender portal tenant The users signed in during the same month Matching file names alone do not establish identical content; compare hashes and event context for each device Explanation Correct Answer D:File hashes and supporting device events provide stronger artifact identity than display names. Incorrect Answers A:Names can be reused for distinct files. B:A common tenant does not establish binary identity. C:Sign-in calendar coincidence is not evidence of file sameness.
Question 532 Two endpoints show a file with the same SHA1. An analyst suspects the same payload but the file names differ. What corroboration supports linking them as the same artifact? Both endpoints were onboarded on the same calendar date The device file records have matching hashes and relevant event context, with different names treated as aliases The devices have unrelated local user account names An antivirus policy has the same display name on both devices Explanation Correct Answer B:The same strong file hash plus related file/device events can connect an artifact across differently named copies. Incorrect Answers A:Onboarding dates do not establish that the same executable was observed. C:Unrelated local account names do not identify file content. D:A shared policy display name is not artifact-level evidence.
Question 533 A government contractor needs to determine whether an executable has a known trusted publisher signature. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Query the appropriate endpoint registry-change evidence for the target path Inspect the file's certificate and signer information in relevant endpoint evidence Use Collect investigation package from the device response actions Check pending actions in Action center for the endpoint group Explanation Correct Answer B:Signature details help interpretation but do not guarantee benign behavior. Incorrect Answers A:Registry telemetry records changed keys separately from process creation. C:Investigation packages provide captured artifacts for offline review. D:Pending approval is a workflow state, not absence of an investigation.
Question 534 The insurance provider SOC needs to determine whether an executable has a known trusted publisher signature, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? Signature details help interpretation but do not guarantee benign behavior. Hash matching connects related artifacts across endpoints subject to coverage. Live response supports analyst command execution for investigation. Pending approval is a workflow state, not absence of an investigation. Explanation Correct Answer A:Signature details help interpretation but do not guarantee benign behavior. Incorrect Answers B:Validating whether the same suspicious hash appears on multiple devices does not determine whether an executable has a known trusted publisher signature. C:Running an authorized interactive investigation command on a currently responsive machine does not determine whether an executable has a known trusted publisher signature. D:Reviewing which defender remediation action is still waiting for approval does not determine whether an executable has a known trusted publisher signature.
Question 535 A signed installer is treated as malicious solely because its filename resembles a threat; the analyst has not checked signer identity or certificate status. Which explanation best accounts for the specific failure? File name similarity does not establish publisher signature trustworthiness File event telemetry does not contain the registry-key change records needed for this hunt Approval of pending Defender for Endpoint actions occurs in Action center rather than solely incident status views Ad-hoc remote shell output is not the same as collecting a supported investigation package Explanation Correct Answer A:File name similarity does not establish publisher signature trustworthiness. Incorrect Answers B:File event telemetry does not contain the registry-key change records needed for this hunt. File name similarity does not establish publisher signature trustworthiness. C:Approval of pending Defender for Endpoint actions occurs in Action center rather than solely incident status views. File name similarity does not establish publisher signature trustworthiness. D:Ad-hoc remote shell output is not the same as collecting a supported investigation package. File name similarity does not establish publisher signature trustworthiness.
Question 536 During a controlled investigation, a suspicious executable has an Authenticode signature and a claimed publisher. Which observation most directly verifies the intended technical behavior? DeviceRegistryEvents includes the registry path, old/new value context and initiating process where supported The evidence reveals signer, certificate chain and signature validation status, not just the filename Action center lists the pending action, impacted device and approval/decline status A downloadable collection contains the supported autorun, process and system artifacts, with Action center status Explanation Correct Answer B:The evidence reveals signer, certificate chain and signature validation status, not just the filename. Incorrect Answers A:DeviceRegistryEvents includes the registry path, old/new value context and initiating process where supported; the evidence reveals signer, certificate chain and signature validation status, not just the filename. C:Action center lists the pending action, impacted device and approval/decline status; the evidence reveals signer, certificate chain and signature validation status, not just the filename. D:A downloadable collection contains the supported autorun, process and system artifacts, with Action center status; the evidence reveals signer, certificate chain and signature validation status, not just the filename.
Question 537 A financial services SOC needs to detect modifications to a persistence-related registry key. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Check pending actions in Action center for the endpoint group Initiate a Defender for Endpoint live response session with required permission Hunt relevant file evidence and device occurrences by hash in Defender XDR Query the appropriate endpoint registry-change evidence for the target path Explanation Correct Answer D:Registry telemetry records changed keys separately from process creation. Incorrect Answers A:Pending approval is a workflow state, not absence of an investigation. B:Live response supports analyst command execution for investigation. C:Hash matching connects related artifacts across endpoints subject to coverage.
Question 538 After a suspected ransomware infection, a responder collects an investigation package from the affected Windows device. Why is the package’s Autoruns evidence useful when assessing persistence even if the currently malicious process is no longer running? Startup entry evidence can show registry or other auto-start mechanisms that would relaunch code after reboot Autoruns evidence proves all registry entries are malicious without context An investigation package automatically removes every startup entry from the device Autoruns replaces the need to preserve related process and file evidence Explanation Correct Answer A:The collected Autoruns data identifies configured automatic-start locations and helps the investigator determine potential persistence mechanisms. Incorrect Answers B:Legitimate software also creates autoruns; entries need forensic context. C:The collection package gathers evidence and does not universally remediate startup mechanisms. D:Other process, file and timeline evidence remains necessary to establish what used a startup entry.
Question 539 A hunt looking for Run-key persistence queries only DeviceFileEvents and finds no registry event despite a known key modification. Which explanation best accounts for the specific failure? File event telemetry does not contain the registry-key change records needed for this hunt File name similarity does not establish publisher signature trustworthiness Approval of pending Defender for Endpoint actions occurs in Action center rather than solely incident status views The command is not one of the supported authorized live response process actions Explanation Correct Answer A:File event telemetry does not contain the registry-key change records needed for this hunt. Incorrect Answers B:File name similarity does not establish publisher signature trustworthiness. File event telemetry does not contain the registry-key change records needed for this hunt. C:Approval of pending Defender for Endpoint actions occurs in Action center rather than solely incident status views. File event telemetry does not contain the registry-key change records needed for this hunt. D:The command is not one of the supported authorized live response process actions. File event telemetry does not contain the registry-key change records needed for this hunt.
Question 540 A device investigation package contains a suspicious auto-start registry entry. Which additional evidence would strengthen a persistence finding rather than simply confirming that the key exists? A different tenant has a similar registry key name The machine’s Microsoft Sentinel workbook opens successfully The autorun entry aligns with an unapproved executable and prior device process or file activity on the same host An unrelated user has a high-severity mailbox phishing alert Explanation Correct Answer C:Correlating an autorun entry with the actual executable and host activity supports a persistence interpretation rather than assuming every autorun is malicious. Incorrect Answers A:A matching string in another environment cannot establish this device’s attack chain. B:Workbook availability is not persistence evidence. D:An unrelated mail alert cannot establish the registry entry’s purpose on this device.
