ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 85

Question 840

Post-containment analysis identified this issue for correction: An Azure subscription shows an unexpected NSG rule allowing RDP from all public IPs. Which targeted analysis or corrective follow-up determines what trusted recovery requires?

  1. Assess exposed objects and restore intended private access policies
  2. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  3. Remove the unauthorized rule and restrict impacted management access
  4. Review affected VM sign-ins and reinstate approved NSG configuration

Explanation

Correct Answer

D:

A corrected rule alone does not prove the server was not accessed; response staff can use these findings about which Azure record identifies the configuration change to decide what eradication and recovery actually require.

Incorrect Answers

A:

Recovery includes data-sensitivity review and partner migration checks; the other incident centers on whether object exposure resulted from public access settings, not this post-containment assessment question about which Azure record identifies the configuration change.

B:

Guardrails detect or prevent excessive ingress; the case needs post-containment assessment addressing which Azure record identifies the configuration change; future hardening is not current-state recovery.

C:

Restoring ingress policy reduces exposure immediately; when judging which Azure record identifies the configuration change, temporary protection does not complete correction; this is instead initial containment or preservation.

Question 841

The response record begins with an unresolved observation: A Google Cloud project receives an unexpected role binding that grants broad storage access to a service account. What documentation or telemetry would most reliably support the incident determination?

  1. Revoke the unapproved role binding and constrain the service account
  2. Inspect Cloud Audit Logs for service-account key creation and caller identity
  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

C:

Administrative audit records can identify who changed the binding; this permits a traceable finding about which Google Cloud events show entitlement changes before the team makes a disruptive change.

Incorrect Answers

A:

Identity containment limits additional resource access; the case needs evidence validation addressing which Google Cloud events show entitlement changes; immediate protection does not substantiate findings.

B:

A newly minted key may allow access beyond the initial session; the relevant condition for that step is which identity event explains potential long-lived access, which is not shown for which Google Cloud events show entitlement changes.

D:

Governance reduces excessive role grants; the requirement concerns which Google Cloud events show entitlement changes, so prevention is not incident verification.

Question 842

A triage analyst needs to test a report involving these details: An Azure VM is implicated in data theft, but its disk is scheduled for replacement during routine deployment. Which evidence collection or correlation is most relevant to this claim?

  1. Create authorized disk snapshots and investigate copies before clean rebuild
  2. Suspend destructive redeployment and isolate the VM with approved network controls
  3. Review managed disk, VM and relevant activity metadata before reprovisioning
  4. Inspect Azure Activity Log events for the network security group write operation
  5. Predefine Azure snapshot and network isolation playbooks

Explanation

Correct Answer

C:

A replacement operation could remove the disks needed for examination; it connects the question of how to retain Azure compute evidence to an observable record and a reproducible check.

Incorrect Answers

A:

Disk snapshots preserve storage state but do not automatically capture all RAM; when judging how to retain Azure compute evidence, recovery is not factual verification; this is instead trusted restoration.

B:

Controlled access keeps the system from continuing external traffic; for how to retain Azure compute evidence, immediate protection does not substantiate findings; evidence validation remains necessary.

D:

Control-plane activity captures resource-management changes within the retention scope; this serves which Azure record identifies the configuration change, whereas the requested result is evidence validation involving how to retain Azure compute evidence.

E:

Cloud-native evidence collection should be rehearsed; prevention is not incident verification in the decision about how to retain Azure compute evidence.

Question 843

Before destructive cleanup is authorized, the team faces this situation: An Azure administrator finds secret-read activity in a Key Vault following a privileged sign-in. Which protective response should the coordinator authorize now?

  1. Rotate exposed secrets and inspect consumers for unauthorized use
  2. Disable the compromised identity and revoke unauthorized app secrets
  3. Restrict the implicated principal's vault data access and revoke active credentials
  4. Correlate Key Vault data-plane audit events with Entra identity activity

Explanation

Correct Answer

C:

Identity and data-plane controls limit additional secret retrieval; the scope of this restriction follows which telemetry can show secret access rather than indiscriminately changing unrelated assets.

Incorrect Answers

A:

A previously read secret may remain useful even after permission removal; corrective follow-through follows initial protection in the decision about which telemetry can show secret access.

B:

Both user and service principal paths can retain access; the activity targets where to investigate identity and application changes; initial containment or preservation here concerns which telemetry can show secret access.

D:

Resource management logs alone may not show every secret read; for which telemetry can show secret access, investigation alone does not control current conditions; initial containment or preservation remains necessary.

Question 844

A security analyst is asked to validate the following reported behavior: Investigators suspect an Amazon S3 bucket was read using a stolen access key but only management events are available. Which check can confirm the relevant facts before a disruptive action?

  1. Check whether CloudTrail S3 data events were enabled for the bucket
  2. Enable appropriate S3 object data events for high-risk data stores
  3. Query organization-wide CloudTrail events by access key and region
  4. Revoke the exposed key and tighten the bucket's effective access

Explanation

Correct Answer

A:

Object-level API activity generally requires configured data event collection; for this investigation, the relevant uncertainty is why the audit record lacks individual object reads, so independent confirmation matters.

Incorrect Answers

B:

Targeted logging strengthens future disclosure investigations; for why the audit record lacks individual object reads, prevention is not incident verification; evidence validation remains necessary.

C:

API event records can trace principal actions across affected regions; the other incident centers on which record reconstructs cross-region API actions, not this evidence validation question about why the audit record lacks individual object reads.

D:

Stopping credential and data access is urgent despite log gaps; the goal is evidence validation for why the audit record lacks individual object reads. Immediate protection does not substantiate findings.

Question 845

The response record begins with an unresolved observation: A multicloud response requires correlating Azure, AWS and Google events with clocks recorded in different zones. What documentation or telemetry would most reliably support the incident determination?

  1. Normalize event times to UTC while preserving source timestamps and clock offsets
  2. Protect exports from all three providers before analysts merge records
  3. Standardize time synchronization and log schemas across cloud tenants
  4. Inspect automation sequence, snapshots and instance metadata retention

Explanation

Correct Answer

A:

Comparable timing supports sequence analysis without altering raw evidence; it makes the determination of whether event timestamps form a reliable unified timeline defensible and reviewable by the incident owner.

Incorrect Answers

B:

Keeping originals prevents later enrichment from overwriting source data; when judging whether event timestamps form a reliable unified timeline, immediate protection does not substantiate findings; this is instead initial containment or preservation.

C:

Consistent telemetry accelerates future cross-platform investigations; for whether event timestamps form a reliable unified timeline, prevention is not incident verification; evidence validation remains necessary.

D:

Destructive cleanup may erase the only persistent artifacts; the relevant condition for that step is whether remediation destroys evidence before acquisition, which is not shown for whether event timestamps form a reliable unified timeline.

Question 846

Active first response is underway for the following condition: An attacker disables centralized audit export from a tenant shortly before modifying access policies. What is the most appropriate short-term restriction or first-response decision?

  1. Reconstruct actions from available provider and downstream service logs
  2. Restore protected logging and restrict identities able to alter audit sinks
  3. Restrict identities authorized to modify retention and stop deletion operations
  4. Inspect audit-export configuration changes and independent sink receipt records

Explanation

Correct Answer

B:

Containment protects remaining records and future visibility; it protects the affected workflow while investigators continue resolving whether log tampering obscured follow-on actions.

Incorrect Answers

A:

Investigators must mark periods where coverage is incomplete; the case needs initial containment or preservation addressing whether log tampering obscured follow-on actions; corrective follow-through follows initial protection.

C:

Separating backup control from workload administration limits damage; this serves whether backup immutability was weakened before destructive changes, whereas the requested result is initial containment or preservation involving whether log tampering obscured follow-on actions.

D:

Control-plane disablement may create evidence gaps after the change; the requirement concerns whether log tampering obscured follow-on actions, so investigation alone does not control current conditions.

Question 847

The incident is not yet closed. Response staff report: Investigators suspect an Amazon S3 bucket was read using a stolen access key but only management events are available. The incident owner wants a corroborating check and a protective action before recovery begins. Which TWO choices fit these separate tasks? (Choose TWO.)

  1. Assess alternative evidence and restore properly scoped data-event logging
  2. Revoke the exposed key and tighten the bucket's effective access
  3. Use temporary credentials and central CloudTrail monitoring
  4. Enable appropriate S3 object data events for high-risk data stores
  5. Check whether CloudTrail S3 data events were enabled for the bucket

Explanation

Correct Answers

B:

Stopping credential and data access is urgent despite log gaps; within the combined response for why the audit record lacks individual object reads, this supplies initial containment or preservation: the immediate response addresses why the audit record lacks individual object reads while the team preserves relevant case records.

E:

Object-level API activity generally requires configured data event collection; within the combined response for why the audit record lacks individual object reads, this supplies evidence validation: the objective is to establish why the audit record lacks individual object reads; the result can then guide the later protective decision.

Incorrect Answers

A:

Investigation should distinguish missing logs from proof of no reads; corrective follow-through follows initial protection in the decision about why the audit record lacks individual object reads.

C:

Short-lived identity reduces replay windows; the relevant condition for that step is which record reconstructs cross-region API actions, which is not shown for why the audit record lacks individual object reads.

D:

Targeted logging strengthens future disclosure investigations; for why the audit record lacks individual object reads, prevention cannot replace immediate action; initial containment or preservation remains necessary.

Question 848

The owner must verify the return to a trusted state for the following: An Azure administrator finds secret-read activity in a Key Vault following a privileged sign-in. Choose THREE actions that separately (1) verify the reported facts, (2) protect against immediate harm and (3) correct the underlying failure before service returns. (Choose THREE.)

  1. Rotate exposed secrets and inspect consumers for unauthorized use
  2. Alert on high-risk sign-ins and unexpected application credential changes
  3. Correlate Key Vault data-plane audit events with Entra identity activity
  4. Predefine Azure snapshot and network isolation playbooks
  5. Enable suitable Key Vault diagnostics and review privileged secret access
  6. Restrict the implicated principal's vault data access and revoke active credentials

Explanation

Correct Answers

A:

A previously read secret may remain useful even after permission removal; within the combined response for which telemetry can show secret access, this supplies trusted restoration: the affected workflow should not be considered trusted until the issue of which telemetry can show secret access is resolved.

C:

Resource management logs alone may not show every secret read; within the combined response for which telemetry can show secret access, this supplies evidence validation: this evidence is scoped to which telemetry can show secret access, not a generic system-health reading.

F:

Identity and data-plane controls limit additional secret retrieval; within the combined response for which telemetry can show secret access, this supplies initial containment or preservation: it restricts the path implicated in which telemetry can show secret access; later eradication and restoration remain separate decisions.

Incorrect Answers

B:

Identity monitoring can reveal persistence beyond passwords; the relevant condition for that step is where to investigate identity and application changes, which is not shown for which telemetry can show secret access.

D:

Cloud-native evidence collection should be rehearsed; this serves how to retain Azure compute evidence, whereas the requested result is trusted restoration involving which telemetry can show secret access.

E:

Central audit collection improves visibility into sensitive operations; the case needs trusted restoration addressing which telemetry can show secret access; future hardening is not current-state recovery.

Question 849

The team wants a measurable hardening change following this situation: A cloud workload has a public security group rule exposing its remote administration port to every address. What improvement best addresses the root weakness in a future incident?

  1. Use immutable backup design with independent administrative controls
  2. Compare effective ingress rules with recent configuration-change audit events
  3. Review access history, remove unauthorized changes and rotate exposed credentials
  4. Use policy-as-code checks for administrative ingress rules

Explanation

Correct Answer

D:

Preventive review catches accidental public exposure; the ongoing control is targeted at whether cloud network policy introduced internet exposure, rather than a one-time emergency fix.

Incorrect Answers

A:

Protection should withstand compromise of ordinary workload identities; the other incident centers on whether backup immutability was weakened before destructive changes, not this recurrence prevention question about whether cloud network policy introduced internet exposure.

B:

A broad public rule makes the service reachable regardless of intended management design; when judging whether cloud network policy introduced internet exposure, an investigation is not recurrence prevention; this is instead evidence validation.

C:

Closing the port alone cannot undo possible prior logins; for whether cloud network policy introduced internet exposure, case recovery is not future-risk control; recurrence prevention remains necessary.

Question 850

Cleanup is not considered complete. The case record describes: An Amazon EC2 instance makes unusual outbound connections and might be running an attacker-controlled process. Which remediation task is necessary rather than merely suppressing the visible symptom?

  1. Maintain preapproved isolation groups and forensic snapshot procedures
  2. Apply a restrictive security group or approved isolation mechanism to the instance
  3. Review subsequent actions by the role and restore approved IAM permissions
  4. Snapshot relevant EBS volumes and redeploy from a trusted image

Explanation

Correct Answer

D:

Disk capture and clean replacement address evidence and persistence separately; the recovery decision is tied to how to isolate suspected AWS compute without destroying evidence, not merely to reduced alert volume.

Incorrect Answers

A:

Prepared tooling avoids ad hoc instance termination; the case needs trusted restoration addressing how to isolate suspected AWS compute without destroying evidence; future hardening is not current-state recovery.

B:

Network quarantine limits egress while preserving disks for collection; when judging how to isolate suspected AWS compute without destroying evidence, temporary protection does not complete correction; this is instead initial containment or preservation.

C:

Rollback requires assessing what the expanded privileges enabled; that method could help with which AWS audit events explain privilege escalation; the trusted restoration decision here involves how to isolate suspected AWS compute without destroying evidence.
