ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 94

Question 930

To avoid broad unnecessary disruption, responders consider this finding: An Azure storage account was unintentionally configured for anonymous blob reads during a migration. Which operational control should take effect first?

  1. Review effective container access settings and anonymous request evidence
  2. Suspend deployment of the affected digest and restrict registry write access
  3. Enforce policies that disallow unnecessary public blob access
  4. Assess exposed objects and restore intended private access policies
  5. Disable unintended anonymous access while retaining request and configuration logs

Explanation

Correct Answer

E:

Public retrieval should cease without erasing exposure evidence; this reduces current exposure associated with whether object exposure resulted from public access settings and permits later corrective work.

Incorrect Answers

A:

Storage exposure depends on both account and container configurations; when judging whether object exposure resulted from public access settings, investigation alone does not control current conditions; this is instead evidence validation.

B:

Digest-level containment prevents promotion of the tainted image; that method could help with whether mutable image tags conceal a supply-chain compromise; the initial containment or preservation decision here involves whether object exposure resulted from public access settings.

C:

Preventive governance catches exposure before release; the requirement concerns whether object exposure resulted from public access settings, so prevention cannot replace immediate action.

D:

Recovery includes data-sensitivity review and partner migration checks; the goal is initial containment or preservation for whether object exposure resulted from public access settings. Corrective follow-through follows initial protection.

Question 931

The team needs temporary protection and must retain evidence. The observed event is: An AWS access key is used from an unapproved IP to call resource-creation APIs in multiple regions. What narrowly scoped action would best control the immediate risk?

  1. Query organization-wide CloudTrail events by access key and region
  2. Find unauthorized resources, remove them after evidence capture and reissue scoped credentials
  3. Revoke the exposed key and tighten the bucket's effective access
  4. Deactivate the exposed access key and restrict associated permissions

Explanation

Correct Answer

D:

Credential containment prevents new cloud resources from being created; this is a first-response safeguard for which record reconstructs cross-region API actions, not a substitute for full root-cause analysis.

Incorrect Answers

A:

API event records can trace principal actions across affected regions; for which record reconstructs cross-region API actions, investigation alone does not control current conditions; initial containment or preservation remains necessary.

B:

Recovery includes cost and persistence cleanup; the requirement concerns which record reconstructs cross-region API actions, so corrective follow-through follows initial protection.

C:

Stopping credential and data access is urgent despite log gaps; this serves why the audit record lacks individual object reads, whereas the requested result is initial containment or preservation involving which record reconstructs cross-region API actions.

Question 932

An evidence-led review starts with the following report: An attacker disables centralized audit export from a tenant shortly before modifying access policies. What investigation should establish the disputed activity and its timeline?

  1. Restore protected logging and restrict identities able to alter audit sinks
  2. Reconstruct actions from available provider and downstream service logs
  3. Identify attached volumes, relevant runtime events and upcoming termination action
  4. Enumerate API keys, service principals and session use in audit history
  5. Inspect audit-export configuration changes and independent sink receipt records
  6. Use separate security accounts and tamper-resistant log storage

Explanation

Correct Answer

E:

Control-plane disablement may create evidence gaps after the change; this evidence is scoped to whether log tampering obscured follow-on actions, not a generic system-health reading.

Incorrect Answers

A:

Containment protects remaining records and future visibility; the goal is evidence validation for whether log tampering obscured follow-on actions. Immediate protection does not substantiate findings.

B:

Investigators must mark periods where coverage is incomplete; recovery is not factual verification in the decision about whether log tampering obscured follow-on actions.

C:

Ephemeral compute replacement can destroy disk state and local logs; the activity targets whether termination will erase useful host evidence; evidence validation here concerns whether log tampering obscured follow-on actions.

D:

Interactive console access is only one possible authorization route; the activity targets which identities still allow malicious API actions; evidence validation here concerns whether log tampering obscured follow-on actions.

F:

Administrative separation reduces attacker ability to hide traces; the requirement concerns whether log tampering obscured follow-on actions, so prevention is not incident verification.

Question 933

The incident is not yet closed. Response staff report: Automated cloud remediation deletes suspicious instances without preserving their attached storage or identity context. Which short-term measure protects the affected process or asset?

  1. Require a preservation checkpoint before automatic termination
  2. Capture disks and metadata then redeploy clean instances with approved controls
  3. Inspect automation sequence, snapshots and instance metadata retention
  4. Protect exports from all three providers before analysts merge records

Explanation

Correct Answer

A:

The guardrail protects evidence while allowing later replacement; it restricts the path implicated in whether remediation destroys evidence before acquisition; later eradication and restoration remain separate decisions.

Incorrect Answers

B:

A sequenced workflow balances forensics and service recovery; corrective follow-through follows initial protection in the decision about whether remediation destroys evidence before acquisition.

C:

Destructive cleanup may erase the only persistent artifacts; the case needs initial containment or preservation addressing whether remediation destroys evidence before acquisition; investigation alone does not control current conditions.

D:

Keeping originals prevents later enrichment from overwriting source data; the relevant condition for that step is whether event timestamps form a reliable unified timeline, which is not shown for whether remediation destroys evidence before acquisition.

Question 934

The team requires traceable proof for an event described as follows: An organization assumes a cloud provider will preserve every customer application log after a tenant account is compromised. What should be correlated to determine whether the case finding is justified?

  1. Document shared-responsibility assignments in cloud incident playbooks
  2. Map the contract and shared-responsibility model to the affected log sources
  3. Classify compromised identity, customer configuration and provider-managed service components
  4. Enable authorized export of existing tenant logs to protected storage

Explanation

Correct Answer

B:

Cloud providers secure underlying services but customers often configure application logging and retention; this permits a traceable finding about which party is responsible for tenant-specific evidence retention before the team makes a disruptive change.

Incorrect Answers

A:

Clear roles reduce response gaps across service boundaries; the goal is evidence validation for which party is responsible for tenant-specific evidence retention. Prevention is not incident verification.

C:

The responsible party differs by the resource and underlying failure; it is meant to address which responsibility boundary controls remediation, not evidence validation for which party is responsible for tenant-specific evidence retention.

D:

Immediate preservation reduces loss from service-specific retention limits; when judging which party is responsible for tenant-specific evidence retention, immediate protection does not substantiate findings; this is instead authorized visibility or enforcement preparation.

Question 935

The team wants a measurable hardening change following this situation: Cloud investigators do not know whether the incident affects the tenant, provider platform or a managed service. What improvement best addresses the root weakness in a future incident?

  1. Classify compromised identity, customer configuration and provider-managed service components
  2. Document customer-owned fixes and provider dependencies before service restoration
  3. Maintain service-specific responsibility matrices and support escalation contacts
  4. Stream container audit and runtime events to durable centralized stores

Explanation

Correct Answer

C:

Prepared boundaries improve cloud incident coordination; the ongoing control is targeted at which responsibility boundary controls remediation, rather than a one-time emergency fix.

Incorrect Answers

A:

The responsible party differs by the resource and underlying failure; the case needs recurrence prevention addressing which responsibility boundary controls remediation; an investigation is not recurrence prevention.

B:

Recovery plans should include both sides' obligations; when judging which responsibility boundary controls remediation, case recovery is not future-risk control; this is instead trusted restoration.

D:

Short-lived infrastructure needs durable telemetry; the relevant condition for that step is which cloud artifacts outlive short-lived compute instances, which is not shown for which responsibility boundary controls remediation.

Question 936

A responder is tasked with limiting immediate impact after this report: Responders discover that ephemeral containers vanished after autoscaling removed suspected workloads. Which immediate safeguard protects the case while later remediation is planned?

  1. Reconstruct the workload from signed images and correlated platform logs
  2. Restrict compromised cross-region identities while preserving logs in every affected scope
  3. Preserve control-plane records and prevent further deletion of implicated images
  4. Review orchestrator events, centralized logs and image metadata

Explanation

Correct Answer

C:

Evidence external to containers survives ordinary replacement; the scope of this restriction follows which cloud artifacts outlive short-lived compute instances rather than indiscriminately changing unrelated assets.

Incorrect Answers

A:

Recovery relies on provenance and off-host observability; when judging which cloud artifacts outlive short-lived compute instances, corrective follow-through follows initial protection; this is instead trusted restoration.

B:

Identity containment must cover all reachable deployments; the other incident centers on whether the investigation includes regional activity, not this initial containment or preservation question about which cloud artifacts outlive short-lived compute instances.

D:

Ephemeral workloads can disappear before investigators examine their local filesystem; the goal is initial containment or preservation for which cloud artifacts outlive short-lived compute instances. Investigation alone does not control current conditions.

Question 937

The response record begins with an unresolved observation: A company assigns a data-loss prevention policy that blocks all attachments, causing employees to use personal messaging apps. What documentation or telemetry would most reliably support the incident determination?

  1. Provide an approved secure exception process and restrict actual unauthorized sharing
  2. Review blocked business workflows and observed unsanctioned transfer channels
  3. Inspect whistleblowing escalation and confidential incident intake procedures
  4. Measure user friction and update DLP controls with targeted exceptions

Explanation

Correct Answer

B:

Unusable policies may push sensitive data outside enterprise monitoring; it makes the determination of whether preventive controls created unsafe workarounds defensible and reviewable by the incident owner.

Incorrect Answers

A:

A workable controlled path reduces immediate policy bypass; the case needs evidence validation addressing whether preventive controls created unsafe workarounds; immediate protection does not substantiate findings.

C:

Reports against executives require independent handling to prevent suppression; the other incident centers on whether reporting channels bypass a conflict of interest, not this evidence validation question about whether preventive controls created unsafe workarounds.

D:

Effective prevention must support normal authorized operations; the requirement concerns whether preventive controls created unsafe workarounds, so prevention is not incident verification.

Question 938

A control owner is preparing preventive actions after observing: Following insider data theft, a business team declares success once the suspect user is suspended despite active shared credentials. What tested hardening or process measure follows from the lessons learned?

  1. Include service identities and task owners in privileged offboarding
  2. Rotate service secrets and verify no unauthorized data pulls persist
  3. Inventory related shared tokens, sessions and delegated resources
  4. Minimize shared secrets and use attributable identities with revocation hooks

Explanation

Correct Answer

D:

Individual authorization improves incident control; it makes the lesson about whether access containment is complete part of normal operations.

Incorrect Answers

A:

Lifecycle coverage prevents retained backdoors; the relevant condition for that step is whether non-person identity persistence remains, which is not shown for whether access containment is complete.

B:

Recovery needs evidence that continued access has stopped; case recovery is not future-risk control in the decision about whether access containment is complete.

C:

One disabled login may leave alternate authorized routes functional; the case needs recurrence prevention addressing whether access containment is complete; an investigation is not recurrence prevention.

Question 939

The first task is to corroborate an alert. The case notes state: A support analyst queries records of celebrities without a business case and exports hundreds of profiles. What should the investigator examine to distinguish a substantiated finding from an assumption?

  1. Correlate sensitive record reads with assigned cases and export logs
  2. Detect access to sensitive profiles without matching business transactions
  3. Correlate query volume, time, business tasks and destination transfer records
  4. Suspend unusual bulk export privileges and preserve audit trails

Explanation

Correct Answer

A:

Legitimate role membership does not explain accesses outside assigned duties; the objective is to establish whether database access patterns show insider snooping; the result can then guide the later protective decision.

Incorrect Answers

B:

Behavioral baselines reveal suspicious but authenticated activity; when judging whether database access patterns show insider snooping, prevention is not incident verification; this is instead recurrence prevention.

C:

Large night exports can be suspicious when outside normal assigned work; the activity targets whether unusual legitimate tooling masks insider exfiltration; evidence validation here concerns whether database access patterns show insider snooping.

D:

Targeted containment limits further disclosure while findings are reviewed; the requirement concerns whether database access patterns show insider snooping, so immediate protection does not substantiate findings.

Question 940

The team wants a measurable hardening change following this situation: A company allows departing administrators to retain remote tokens until the end of a monthly access review. What improvement best addresses the root weakness in a future incident?

  1. Automate identity revocation from verified HR lifecycle events
  2. Use privileged access management with session recording and just-in-time grants
  3. Compare termination timestamps with active remote sessions and token expiration
  4. Audit post-termination activity and reclaim registered devices and secrets

Explanation

Correct Answer

A:

Event-driven offboarding reduces exposure windows; its effectiveness can be exercised against the warning conditions associated with whether offboarding revokes privileges promptly.

Incorrect Answers

B:

Traceability supports insider investigation and prevention; the activity targets whether insider action attribution is possible; recurrence prevention here concerns whether offboarding revokes privileges promptly.

C:

A delayed review leaves usable credentials after authorization ends; for whether offboarding revokes privileges promptly, an investigation is not recurrence prevention; recurrence prevention remains necessary.

D:

Offboarding completeness includes machine and application credentials; the requirement concerns whether offboarding revokes privileges promptly, so case recovery is not future-risk control.
