Question 820
Before making any disruptive change, an investigator is handed these observations: A cloud administrator revokes one user's console access but leaves active service tokens for an automation identity exposed. Which source best supports the incident finding before responders modify the environment?
- Enumerate API keys, service principals and session use in audit history
- Revoke exposed service tokens and restrict their effective roles
- Inspect audit-export configuration changes and independent sink receipt records
- Inventory machine identities and enforce secret rotation and least privilege
Explanation
Correct Answer
A:Interactive console access is only one possible authorization route; for this investigation, the relevant uncertainty is which identities still allow malicious API actions, so independent confirmation matters.
Incorrect Answers
B:Credential-specific containment stops unattended API calls; the goal is evidence validation for which identities still allow malicious API actions. Immediate protection does not substantiate findings.
C:Control-plane disablement may create evidence gaps after the change; that method could help with whether log tampering obscured follow-on actions; the evidence validation decision here involves which identities still allow malicious API actions.
D:Workload credentials need lifecycle controls like human accounts; the case needs evidence validation addressing which identities still allow malicious API actions; prevention is not incident verification.
Question 821
Before granting routine access again, the team reviews this case: A cloud workload has a public security group rule exposing its remote administration port to every address. What must the response owner validate as part of safe recovery?
- Assess accessed object scope and issue replacement credentials to legitimate workloads
- Narrow ingress to approved management sources immediately
- Review access history, remove unauthorized changes and rotate exposed credentials
- Use policy-as-code checks for administrative ingress rules
Explanation
Correct Answer
C:Closing the port alone cannot undo possible prior logins; it is the corrective action needed for whether cloud network policy introduced internet exposure after the immediate hazard is controlled.
Incorrect Answers
A:Recovery must distinguish data disclosure from service restoration; the relevant condition for that step is whether API credentials were used for unauthorized reads, which is not shown for whether cloud network policy introduced internet exposure.
B:A specific network policy change reduces attack surface without deleting the host; temporary protection does not complete correction in the decision about whether cloud network policy introduced internet exposure.
D:Preventive review catches accidental public exposure; when judging whether cloud network policy introduced internet exposure, future hardening is not current-state recovery; this is instead recurrence prevention.
Question 822
A control owner is preparing preventive actions after observing: A public Cloud Storage object is discovered in a bucket intended for internal engineering data. What tested hardening or process measure follows from the lessons learned?
- Use organization policy restrictions and recurring storage exposure checks
- Use IAM Recommender and policy reviews with security monitoring
- Inspect bucket IAM, public access prevention and object request evidence
- Determine affected objects and validate intended internal access
Explanation
Correct Answer
A:Preventive controls reduce accidental public data publication; it makes the lesson about whether an access policy exposed cloud objects part of normal operations.
Incorrect Answers
B:Governance reduces excessive role grants; the activity targets which Google Cloud events show entitlement changes; recurrence prevention here concerns whether an access policy exposed cloud objects.
C:Public exposure is governed by effective policy and object-access settings; the case needs recurrence prevention addressing whether an access policy exposed cloud objects; an investigation is not recurrence prevention.
D:Recovery must handle data disclosure as well as policy correction; when judging whether an access policy exposed cloud objects, case recovery is not future-risk control; this is instead trusted restoration.
Question 823
A long-term control assessment uses this recent event: An AWS account's central CloudTrail trail is stopped just before new IAM users appear. Which change provides measurable prevention rather than an emergency workaround?
- Alert on sensitive IAM policy attachments and enforce least privilege
- Remove unauthorized IAM identities and reconstruct actions during the gap
- Use separate log archive accounts and alert on trail changes
- Correlate StopLogging events with IAM user-creation activity and downstream archives
Explanation
Correct Answer
C:Administrative separation makes audit tampering harder; this turns the weakness behind whether audit tampering preceded unauthorized identities into a measurable prevention requirement.
Incorrect Answers
A:High-impact entitlement changes should be monitored; the relevant condition for that step is which AWS audit events explain privilege escalation, which is not shown for whether audit tampering preceded unauthorized identities.
B:Investigators should not assume the missing interval was benign; for whether audit tampering preceded unauthorized identities, case recovery is not future-risk control; recurrence prevention remains necessary.
D:Independent logging may preserve evidence of the attempt to suppress telemetry; the goal is recurrence prevention for whether audit tampering preceded unauthorized identities. An investigation is not recurrence prevention.
Question 824
The team needs temporary protection and must retain evidence. The observed event is: An unknown access key downloads large volumes of objects from a cloud storage container. What narrowly scoped action would best control the immediate risk?
- Revoke exposed service tokens and restrict their effective roles
- Correlate data-access audit events, credential identity and object request timing
- Prefer short-lived workload identity and monitor bulk object reads
- Assess accessed object scope and issue replacement credentials to legitimate workloads
- Disable or rotate the exposed key and constrain storage access
Explanation
Correct Answer
E:Stopping credential replay limits continued downloads; it restricts the path implicated in whether API credentials were used for unauthorized reads; later eradication and restoration remain separate decisions.
Incorrect Answers
A:Credential-specific containment stops unattended API calls; the relevant condition for that step is which identities still allow malicious API actions, which is not shown for whether API credentials were used for unauthorized reads.
B:API activity can identify which key accessed which protected objects when logging is enabled; the requirement concerns whether API credentials were used for unauthorized reads, so investigation alone does not control current conditions.
C:Reducing static-key use narrows long-term credential risk; the goal is initial containment or preservation for whether API credentials were used for unauthorized reads. Prevention cannot replace immediate action.
D:Recovery must distinguish data disclosure from service restoration; corrective follow-through follows initial protection in the decision about whether API credentials were used for unauthorized reads.
Question 825
The initial scene or threat protection decision concerns the following: An organization assumes a cloud provider will preserve every customer application log after a tenant account is compromised. What controlled initial step is justified before more disruptive network or cloud actions?
- Open provider support and customer security response channels in parallel as warranted
- Establish independent evidence collection and restore procedures for customer workloads
- Map the contract and shared-responsibility model to the affected log sources
- Enable authorized export of existing tenant logs to protected storage
Explanation
Correct Answer
D:Immediate preservation reduces loss from service-specific retention limits; the first response establishes the necessary visibility or enforcement point for which party is responsible for tenant-specific evidence retention.
Incorrect Answers
A:Coordinated escalation avoids delay at an unclear boundary; the activity targets which responsibility boundary controls remediation; authorized visibility or enforcement preparation here concerns which party is responsible for tenant-specific evidence retention.
B:Cloud operations cannot assume provider backups cover every investigation need; the case needs authorized visibility or enforcement preparation addressing which party is responsible for tenant-specific evidence retention; corrective follow-through follows initial protection.
C:Cloud providers secure underlying services but customers often configure application logging and retention; when judging which party is responsible for tenant-specific evidence retention, investigation alone does not control current conditions; this is instead evidence validation.
Question 826
A triage analyst needs to test a report involving these details: Cloud investigators do not know whether the incident affects the tenant, provider platform or a managed service. Which evidence collection or correlation is most relevant to this claim?
- Classify compromised identity, customer configuration and provider-managed service components
- Maintain service-specific responsibility matrices and support escalation contacts
- Map the contract and shared-responsibility model to the affected log sources
- Open provider support and customer security response channels in parallel as warranted
Explanation
Correct Answer
A:The responsible party differs by the resource and underlying failure; it connects the question of which responsibility boundary controls remediation to an observable record and a reproducible check.
Incorrect Answers
B:Prepared boundaries improve cloud incident coordination; for which responsibility boundary controls remediation, prevention is not incident verification; evidence validation remains necessary.
C:Cloud providers secure underlying services but customers often configure application logging and retention; this serves which party is responsible for tenant-specific evidence retention, whereas the requested result is evidence validation involving which responsibility boundary controls remediation.
D:Coordinated escalation avoids delay at an unclear boundary; the goal is evidence validation for which responsibility boundary controls remediation. Immediate protection does not substantiate findings.
Question 827
The owner must verify the return to a trusted state for the following: An unknown user invokes Google Cloud API operations that create new service-account keys. What corrective work is needed before routine operations resume?
- Review actions performed under the expanded grant and restore reviewed IAM policy
- Delete unauthorized keys after evidence capture and review their subsequent usage
- Limit service-account key creation and prefer short-lived impersonation
- Disable suspicious keys and restrict the creating principal's access
Explanation
Correct Answer
B:A key may have been copied to an external operator; technical closure should demonstrate that the control gap behind which identity event explains potential long-lived access is actually corrected.
Incorrect Answers
A:Recovery requires both least-privilege restoration and scoping; the activity targets which Google Cloud events show entitlement changes; trusted restoration here concerns which identity event explains potential long-lived access.
C:Reducing downloadable keys narrows persistence options; for which identity event explains potential long-lived access, future hardening is not current-state recovery; trusted restoration remains necessary.
D:Both the credential and source identity need containment; the requirement concerns which identity event explains potential long-lived access, so temporary protection does not complete correction.
Question 828
The incident is resolved, but its root weakness still requires policy attention: A suspicious virtual machine is about to be deleted by an autoscaling group after a failed health check. What durable process or monitoring change would make a repeat less likely?
- Build acquisition hooks into autoscaling and incident runbooks
- Snapshot relevant disks and preserve instance metadata before trusted replacement
- Prefer short-lived workload identity and monitor bulk object reads
- Identify attached volumes, relevant runtime events and upcoming termination action
Explanation
Correct Answer
A:Automated preservation reduces loss from routine lifecycle events; a periodic review of this safeguard can track the risk described by whether termination will erase useful host evidence.
Incorrect Answers
B:Investigation can continue from copies without retaining compromised production machines indefinitely; the requirement concerns whether termination will erase useful host evidence, so case recovery is not future-risk control.
C:Reducing static-key use narrows long-term credential risk; this serves whether API credentials were used for unauthorized reads, whereas the requested result is recurrence prevention involving whether termination will erase useful host evidence.
D:Ephemeral compute replacement can destroy disk state and local logs; an investigation is not recurrence prevention in the decision about whether termination will erase useful host evidence.
Question 829
The initial scene or threat protection decision concerns the following: A Google Cloud VM may have uploaded data to the internet but investigators have only sparse firewall logs. How should responders limit the damage while retaining the investigation trail?
- Correlate available VPC Flow Logs with guest telemetry and audit activity
- Revoke the unapproved role binding and constrain the service account
- Restrict the suspect VM's egress through approved firewall policies
- Capture persistent disk evidence and redeploy a verified instance
Explanation
Correct Answer
C:Host-specific containment limits ongoing outbound traffic; the protective decision should be recorded and its effect tested against where to find network and workload evidence.
Incorrect Answers
A:Network flows provide metadata and may need configuration before sufficient history exists; investigation alone does not control current conditions in the decision about where to find network and workload evidence.
B:Identity containment limits additional resource access; the other incident centers on which Google Cloud events show entitlement changes, not this initial containment or preservation question about where to find network and workload evidence.
D:Clean compute restoration follows evidence preservation; for where to find network and workload evidence, corrective follow-through follows initial protection; initial containment or preservation remains necessary.
Question 830
An improvement plan must address recurrence after this case: A suspicious user signs into Microsoft Entra ID and creates a new application credential. What should the owner add to the normal control review to reduce recurrence?
- Alert on high-risk sign-ins and unexpected application credential changes
- Enable suitable Key Vault diagnostics and review privileged secret access
- Remove rogue credentials and review downstream token and consent activity
- Correlate Entra sign-in logs with directory audit events for credential additions
Explanation
Correct Answer
A:Identity monitoring can reveal persistence beyond passwords; the ongoing control is targeted at where to investigate identity and application changes, rather than a one-time emergency fix.
Incorrect Answers
B:Central audit collection improves visibility into sensitive operations; the other incident centers on which telemetry can show secret access, not this recurrence prevention question about where to investigate identity and application changes.
C:Recovery must account for access granted to applications; the goal is recurrence prevention for where to investigate identity and application changes. Case recovery is not future-risk control.
D:Identity logs distinguish login activity from application object modifications; an investigation is not recurrence prevention in the decision about where to investigate identity and application changes.
