Question 910
A technical closure review begins after this incident: An AWS incident begins with unexpected IAM policy attachment to an automation role. After the immediate situation is stabilized, what addresses the enabling failure?
- Alert on sensitive IAM policy attachments and enforce least privilege
- Assess alternative evidence and restore properly scoped data-event logging
- Review subsequent actions by the role and restore approved IAM permissions
- Remove the unauthorized policy and restrict the compromised principal
Explanation
Correct Answer
C:Rollback requires assessing what the expanded privileges enabled; it is the corrective action needed for which AWS audit events explain privilege escalation after the immediate hazard is controlled.
Incorrect Answers
A:High-impact entitlement changes should be monitored; for which AWS audit events explain privilege escalation, future hardening is not current-state recovery; trusted restoration remains necessary.
B:Investigation should distinguish missing logs from proof of no reads; the activity targets why the audit record lacks individual object reads; trusted restoration here concerns which AWS audit events explain privilege escalation.
D:Privilege containment reduces potential follow-on API access; temporary protection does not complete correction in the decision about which AWS audit events explain privilege escalation.
Question 911
The response team seeks the relevant control point for this problem: An Azure subscription shows an unexpected NSG rule allowing RDP from all public IPs. What protection would be proportionate to the observed incident?
- Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
- Inspect Azure Activity Log events for the network security group write operation
- Suspend destructive redeployment and isolate the VM with approved network controls
- Remove the unauthorized rule and restrict impacted management access
- Review affected VM sign-ins and reinstate approved NSG configuration
Explanation
Correct Answer
D:Restoring ingress policy reduces exposure immediately; it protects the affected workflow while investigators continue resolving which Azure record identifies the configuration change.
Incorrect Answers
A:Guardrails detect or prevent excessive ingress; the case needs initial containment or preservation addressing which Azure record identifies the configuration change; prevention cannot replace immediate action.
B:Control-plane activity captures resource-management changes within the retention scope; when judging which Azure record identifies the configuration change, investigation alone does not control current conditions; this is instead evidence validation.
C:Controlled access keeps the system from continuing external traffic; this serves how to retain Azure compute evidence, whereas the requested result is initial containment or preservation involving which Azure record identifies the configuration change.
E:A corrected rule alone does not prove the server was not accessed; the goal is initial containment or preservation for which Azure record identifies the configuration change. Corrective follow-through follows initial protection.
Question 912
An evidence-led review starts with the following report: An unknown access key downloads large volumes of objects from a cloud storage container. What investigation should establish the disputed activity and its timeline?
- Prefer short-lived workload identity and monitor bulk object reads
- Compare effective ingress rules with recent configuration-change audit events
- Disable or rotate the exposed key and constrain storage access
- Correlate data-access audit events, credential identity and object request timing
Explanation
Correct Answer
D:API activity can identify which key accessed which protected objects when logging is enabled; this evidence is scoped to whether API credentials were used for unauthorized reads, not a generic system-health reading.
Incorrect Answers
A:Reducing static-key use narrows long-term credential risk; the goal is evidence validation for whether API credentials were used for unauthorized reads. Prevention is not incident verification.
B:A broad public rule makes the service reachable regardless of intended management design; that method could help with whether cloud network policy introduced internet exposure; the evidence validation decision here involves whether API credentials were used for unauthorized reads.
C:Stopping credential replay limits continued downloads; the case needs evidence validation addressing whether API credentials were used for unauthorized reads; immediate protection does not substantiate findings.
Question 913
A triage analyst needs to test a report involving these details: A cloud team stores incident logs in the same account that compromised tenant administrators can delete. Which evidence collection or correlation is most relevant to this claim?
- Validate immutable retention and repository integrity checks
- Normalize event times to UTC while preserving source timestamps and clock offsets
- Use dedicated cross-account log archives with restricted deletion rights
- Replicate available logs to a protected security-owned account
- Review log repository permissions and independent audit-sink access
Explanation
Correct Answer
E:Attacker-controlled accounts can undermine retention and chain of custody; that evidence directly tests the concern about whether evidence storage is isolated from suspect administrators, rather than relying on a single unverified indicator.
Incorrect Answers
A:Trusted evidence should survive customer-workload credential theft; when judging whether evidence storage is isolated from suspect administrators, recovery is not factual verification; this is instead trusted restoration.
B:Comparable timing supports sequence analysis without altering raw evidence; the relevant condition for that step is whether event timestamps form a reliable unified timeline, which is not shown for whether evidence storage is isolated from suspect administrators.
C:Isolation makes forensic records more resilient; the requirement concerns whether evidence storage is isolated from suspect administrators, so prevention is not incident verification.
D:Administrative separation helps preserve evidence during ongoing compromise; the goal is evidence validation for whether evidence storage is isolated from suspect administrators. Immediate protection does not substantiate findings.
Question 914
A post-incident audit examines the following failure mode: A Google Cloud project receives an unexpected role binding that grants broad storage access to a service account. What recurring check or restriction would best address the weakness?
- Review actions performed under the expanded grant and restore reviewed IAM policy
- Limit service-account key creation and prefer short-lived impersonation
- Inspect Cloud Audit Logs for IAM policy modifications and affected principals
- Use IAM Recommender and policy reviews with security monitoring
Explanation
Correct Answer
D:Governance reduces excessive role grants; the control owner can test whether this reduces repeat conditions affecting which Google Cloud events show entitlement changes.
Incorrect Answers
A:Recovery requires both least-privilege restoration and scoping; case recovery is not future-risk control in the decision about which Google Cloud events show entitlement changes.
B:Reducing downloadable keys narrows persistence options; that method could help with which identity event explains potential long-lived access; the recurrence prevention decision here involves which Google Cloud events show entitlement changes.
C:Administrative audit records can identify who changed the binding; when judging which Google Cloud events show entitlement changes, an investigation is not recurrence prevention; this is instead evidence validation.
Question 915
The response team seeks the relevant control point for this problem: An Azure container registry shows an unauthorized image pushed under an existing trusted tag. What protection would be proportionate to the observed incident?
- Suspend deployment of the affected digest and restrict registry write access
- Compare registry manifest digests, push audit records and pipeline release history
- Remove the unauthorized rule and restrict impacted management access
- Redeploy a signed verified image and inspect workloads that pulled the malicious digest
Explanation
Correct Answer
A:Digest-level containment prevents promotion of the tainted image; it protects the affected workflow while investigators continue resolving whether mutable image tags conceal a supply-chain compromise.
Incorrect Answers
B:A familiar tag can reference a different artifact after a malicious overwrite; when judging whether mutable image tags conceal a supply-chain compromise, investigation alone does not control current conditions; this is instead evidence validation.
C:Restoring ingress policy reduces exposure immediately; that method could help with which Azure record identifies the configuration change; the initial containment or preservation decision here involves whether mutable image tags conceal a supply-chain compromise.
D:Recovery must account for prior deployment as well as repository state; the requirement concerns whether mutable image tags conceal a supply-chain compromise, so corrective follow-through follows initial protection.
Question 916
Before granting routine access again, the team reviews this case: A suspicious virtual machine is about to be deleted by an autoscaling group after a failed health check. What must the response owner validate as part of safe recovery?
- Snapshot relevant disks and preserve instance metadata before trusted replacement
- Build acquisition hooks into autoscaling and incident runbooks
- Temporarily suspend the implicated termination workflow under incident authority
- Review access history, remove unauthorized changes and rotate exposed credentials
Explanation
Correct Answer
A:Investigation can continue from copies without retaining compromised production machines indefinitely; technical closure should demonstrate that the control gap behind whether termination will erase useful host evidence is actually corrected.
Incorrect Answers
B:Automated preservation reduces loss from routine lifecycle events; future hardening is not current-state recovery in the decision about whether termination will erase useful host evidence.
C:A controlled hold creates an opportunity for acquisition; the case needs trusted restoration addressing whether termination will erase useful host evidence; temporary protection does not complete correction.
D:Closing the port alone cannot undo possible prior logins; the activity targets whether cloud network policy introduced internet exposure; trusted restoration here concerns whether termination will erase useful host evidence.
Question 917
Active first response is underway for the following condition: An unknown user invokes Google Cloud API operations that create new service-account keys. What is the most appropriate short-term restriction or first-response decision?
- Delete unauthorized keys after evidence capture and review their subsequent usage
- Disable suspicious keys and restrict the creating principal's access
- Revoke the unapproved role binding and constrain the service account
- Inspect Cloud Audit Logs for service-account key creation and caller identity
Explanation
Correct Answer
B:Both the credential and source identity need containment; the immediate response addresses which identity event explains potential long-lived access while the team preserves relevant case records.
Incorrect Answers
A:A key may have been copied to an external operator; the case needs initial containment or preservation addressing which identity event explains potential long-lived access; corrective follow-through follows initial protection.
C:Identity containment limits additional resource access; that method could help with which Google Cloud events show entitlement changes; the initial containment or preservation decision here involves which identity event explains potential long-lived access.
D:A newly minted key may allow access beyond the initial session; the requirement concerns which identity event explains potential long-lived access, so investigation alone does not control current conditions.
Question 918
The coordinator needs corrective action rather than another alert. The event was: A suspicious user signs into Microsoft Entra ID and creates a new application credential. Which follow-through step verifies the weakness was removed?
- Alert on high-risk sign-ins and unexpected application credential changes
- Remove rogue credentials and review downstream token and consent activity
- Disable the compromised identity and revoke unauthorized app secrets
- Rotate exposed secrets and inspect consumers for unauthorized use
Explanation
Correct Answer
B:Recovery must account for access granted to applications; the affected workflow should not be considered trusted until the issue of where to investigate identity and application changes is resolved.
Incorrect Answers
A:Identity monitoring can reveal persistence beyond passwords; the goal is trusted restoration for where to investigate identity and application changes. Future hardening is not current-state recovery.
C:Both user and service principal paths can retain access; the case needs trusted restoration addressing where to investigate identity and application changes; temporary protection does not complete correction.
D:A previously read secret may remain useful even after permission removal; the relevant condition for that step is which telemetry can show secret access, which is not shown for where to investigate identity and application changes.
Question 919
A security analyst is asked to validate the following reported behavior: An Azure administrator finds secret-read activity in a Key Vault following a privileged sign-in. Which check can confirm the relevant facts before a disruptive action?
- Restrict the implicated principal's vault data access and revoke active credentials
- Correlate Entra sign-in logs with directory audit events for credential additions
- Enable suitable Key Vault diagnostics and review privileged secret access
- Correlate Key Vault data-plane audit events with Entra identity activity
Explanation
Correct Answer
D:Resource management logs alone may not show every secret read; the review should retain source and timing information relevant to which telemetry can show secret access.
Incorrect Answers
A:Identity and data-plane controls limit additional secret retrieval; when judging which telemetry can show secret access, immediate protection does not substantiate findings; this is instead initial containment or preservation.
B:Identity logs distinguish login activity from application object modifications; that method could help with where to investigate identity and application changes; the evidence validation decision here involves which telemetry can show secret access.
C:Central audit collection improves visibility into sensitive operations; the requirement concerns which telemetry can show secret access, so prevention is not incident verification.
Question 920
A tabletop exercise is being updated using the following real-world failure: An Azure VM is implicated in data theft, but its disk is scheduled for replacement during routine deployment. Which improvement should be tracked through the next control-assurance cycle?
- Enforce immutable tags, image signatures and least-privilege registry permissions
- Create authorized disk snapshots and investigate copies before clean rebuild
- Review managed disk, VM and relevant activity metadata before reprovisioning
- Predefine Azure snapshot and network isolation playbooks
Explanation
Correct Answer
D:Cloud-native evidence collection should be rehearsed; this turns the weakness behind how to retain Azure compute evidence into a measurable prevention requirement.
Incorrect Answers
A:Artifact integrity controls reduce malicious replacement; the other incident centers on whether mutable image tags conceal a supply-chain compromise, not this recurrence prevention question about how to retain Azure compute evidence.
B:Disk snapshots preserve storage state but do not automatically capture all RAM; for how to retain Azure compute evidence, case recovery is not future-risk control; recurrence prevention remains necessary.
C:A replacement operation could remove the disks needed for examination; the requirement concerns how to retain Azure compute evidence, so an investigation is not recurrence prevention.
