ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 92

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?

  1. Alert on sensitive IAM policy attachments and enforce least privilege
  2. Assess alternative evidence and restore properly scoped data-event logging
  3. Review subsequent actions by the role and restore approved IAM permissions
  4. 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?

  1. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  2. Inspect Azure Activity Log events for the network security group write operation
  3. Suspend destructive redeployment and isolate the VM with approved network controls
  4. Remove the unauthorized rule and restrict impacted management access
  5. 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?

  1. Prefer short-lived workload identity and monitor bulk object reads
  2. Compare effective ingress rules with recent configuration-change audit events
  3. Disable or rotate the exposed key and constrain storage access
  4. 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?

  1. Validate immutable retention and repository integrity checks
  2. Normalize event times to UTC while preserving source timestamps and clock offsets
  3. Use dedicated cross-account log archives with restricted deletion rights
  4. Replicate available logs to a protected security-owned account
  5. 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?

  1. Review actions performed under the expanded grant and restore reviewed IAM policy
  2. Limit service-account key creation and prefer short-lived impersonation
  3. Inspect Cloud Audit Logs for IAM policy modifications and affected principals
  4. 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?

  1. Suspend deployment of the affected digest and restrict registry write access
  2. Compare registry manifest digests, push audit records and pipeline release history
  3. Remove the unauthorized rule and restrict impacted management access
  4. 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?

  1. Snapshot relevant disks and preserve instance metadata before trusted replacement
  2. Build acquisition hooks into autoscaling and incident runbooks
  3. Temporarily suspend the implicated termination workflow under incident authority
  4. 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?

  1. Delete unauthorized keys after evidence capture and review their subsequent usage
  2. Disable suspicious keys and restrict the creating principal's access
  3. Revoke the unapproved role binding and constrain the service account
  4. 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?

  1. Alert on high-risk sign-ins and unexpected application credential changes
  2. Remove rogue credentials and review downstream token and consent activity
  3. Disable the compromised identity and revoke unauthorized app secrets
  4. 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?

  1. Restrict the implicated principal's vault data access and revoke active credentials
  2. Correlate Entra sign-in logs with directory audit events for credential additions
  3. Enable suitable Key Vault diagnostics and review privileged secret access
  4. 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?

  1. Enforce immutable tags, image signatures and least-privilege registry permissions
  2. Create authorized disk snapshots and investigate copies before clean rebuild
  3. Review managed disk, VM and relevant activity metadata before reprovisioning
  4. 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.
