ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 88

Question 870

After technical restoration, responders document the weakness exposed by: An Azure subscription shows an unexpected NSG rule allowing RDP from all public IPs. Which long-term control would reduce exposure to this specific pattern?

  1. Remove the unauthorized rule and restrict impacted management access
  2. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  3. Predefine Azure snapshot and network isolation playbooks
  4. Review affected VM sign-ins and reinstate approved NSG configuration
  5. Inspect Azure Activity Log events for the network security group write operation

Explanation

Correct Answer

B:

Guardrails detect or prevent excessive ingress; this turns the weakness behind which Azure record identifies the configuration change into a measurable prevention requirement.

Incorrect Answers

A:

Restoring ingress policy reduces exposure immediately; one-time protection is not durable prevention in the decision about which Azure record identifies the configuration change.

C:

Cloud-native evidence collection should be rehearsed; the relevant condition for that step is how to retain Azure compute evidence, which is not shown for which Azure record identifies the configuration change.

D:

A corrected rule alone does not prove the server was not accessed; for which Azure record identifies the configuration change, case recovery is not future-risk control; recurrence prevention remains necessary.

E:

Control-plane activity captures resource-management changes within the retention scope; the requirement concerns which Azure record identifies the configuration change, so an investigation is not recurrence prevention.

Question 871

The recurrence-prevention decision is based on this report: Responders discover that ephemeral containers vanished after autoscaling removed suspected workloads. What measure strengthens readiness against the observed event?

  1. Use centralized multi-region log aggregation and region inventory
  2. Review orchestrator events, centralized logs and image metadata
  3. Stream container audit and runtime events to durable centralized stores
  4. Reconstruct the workload from signed images and correlated platform logs

Explanation

Correct Answer

C:

Short-lived infrastructure needs durable telemetry; a periodic review of this safeguard can track the risk described by which cloud artifacts outlive short-lived compute instances.

Incorrect Answers

A:

Broad visibility reduces geographic investigation blind spots; the relevant condition for that step is whether the investigation includes regional activity, which is not shown for which cloud artifacts outlive short-lived compute instances.

B:

Ephemeral workloads can disappear before investigators examine their local filesystem; when judging which cloud artifacts outlive short-lived compute instances, an investigation is not recurrence prevention; this is instead evidence validation.

D:

Recovery relies on provenance and off-host observability; the requirement concerns which cloud artifacts outlive short-lived compute instances, so case recovery is not future-risk control.

Question 872

A case is escalated for independent verification after this finding: A suspicious user signs into Microsoft Entra ID and creates a new application credential. What collection or comparison would validate the reported condition?

  1. Correlate Key Vault data-plane audit events with Entra identity activity
  2. Remove rogue credentials and review downstream token and consent activity
  3. Review managed disk, VM and relevant activity metadata before reprovisioning
  4. Disable the compromised identity and revoke unauthorized app secrets
  5. Alert on high-risk sign-ins and unexpected application credential changes
  6. Correlate Entra sign-in logs with directory audit events for credential additions

Explanation

Correct Answer

F:

Identity logs distinguish login activity from application object modifications; this permits a traceable finding about where to investigate identity and application changes before the team makes a disruptive change.

Incorrect Answers

A:

Resource management logs alone may not show every secret read; this serves which telemetry can show secret access, whereas the requested result is evidence validation involving where to investigate identity and application changes.

B:

Recovery must account for access granted to applications; the requirement concerns where to investigate identity and application changes, so recovery is not factual verification.

C:

A replacement operation could remove the disks needed for examination; it is meant to address how to retain Azure compute evidence, not evidence validation for where to investigate identity and application changes.

D:

Both user and service principal paths can retain access; immediate protection does not substantiate findings in the decision about where to investigate identity and application changes.

E:

Identity monitoring can reveal persistence beyond passwords; the case needs evidence validation addressing where to investigate identity and application changes; prevention is not incident verification.

Question 873

The recovery owner is reviewing the underlying failure in this report: A Google Cloud VM may have uploaded data to the internet but investigators have only sparse firewall logs. What action most directly repairs the affected access, evidence or system state?

  1. Capture persistent disk evidence and redeploy a verified instance
  2. Restrict the suspect VM's egress through approved firewall policies
  3. Rotate exposed secrets and replace the workload under reviewed bindings
  4. Enable appropriate flow logging and endpoint telemetry on sensitive workloads

Explanation

Correct Answer

A:

Clean compute restoration follows evidence preservation; this goes beyond temporary protection and addresses the failure identified through where to find network and workload evidence.

Incorrect Answers

B:

Host-specific containment limits ongoing outbound traffic; the goal is trusted restoration for where to find network and workload evidence. Temporary protection does not complete correction.

C:

Rebuilds without permission repair can repeat the exposure; the activity targets whether workload identity and authorization allowed the read; trusted restoration here concerns where to find network and workload evidence.

D:

Layered visibility improves attribution and scope; the case needs trusted restoration addressing where to find network and workload evidence; future hardening is not current-state recovery.

Question 874

During lessons learned, the security owner reviews this completed incident: An Azure storage account was unintentionally configured for anonymous blob reads during a migration. Which repeatable safeguard best prevents this failure mode in the future?

  1. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  2. Enforce policies that disallow unnecessary public blob access
  3. Assess exposed objects and restore intended private access policies
  4. Review effective container access settings and anonymous request evidence

Explanation

Correct Answer

B:

Preventive governance catches exposure before release; this turns the weakness behind whether object exposure resulted from public access settings into a measurable prevention requirement.

Incorrect Answers

A:

Guardrails detect or prevent excessive ingress; the other incident centers on which Azure record identifies the configuration change, not this recurrence prevention question about whether object exposure resulted from public access settings.

C:

Recovery includes data-sensitivity review and partner migration checks; case recovery is not future-risk control in the decision about whether object exposure resulted from public access settings.

D:

Storage exposure depends on both account and container configurations; the case needs recurrence prevention addressing whether object exposure resulted from public access settings; an investigation is not recurrence prevention.

Question 875

An improvement plan must address recurrence after this case: Automated cloud remediation deletes suspicious instances without preserving their attached storage or identity context. What should the owner add to the normal control review to reduce recurrence?

  1. Require a preservation checkpoint before automatic termination
  2. Use dedicated cross-account log archives with restricted deletion rights
  3. Capture disks and metadata then redeploy clean instances with approved controls
  4. Test cloud response automation for idempotence and preservation steps
  5. Inspect automation sequence, snapshots and instance metadata retention

Explanation

Correct Answer

D:

Safe orchestration avoids irreversible evidence loss; its effectiveness can be exercised against the warning conditions associated with whether remediation destroys evidence before acquisition.

Incorrect Answers

A:

The guardrail protects evidence while allowing later replacement; for whether remediation destroys evidence before acquisition, one-time protection is not durable prevention; recurrence prevention remains necessary.

B:

Isolation makes forensic records more resilient; that method could help with whether evidence storage is isolated from suspect administrators; the recurrence prevention decision here involves whether remediation destroys evidence before acquisition.

C:

A sequenced workflow balances forensics and service recovery; the goal is recurrence prevention for whether remediation destroys evidence before acquisition. Case recovery is not future-risk control.

E:

Destructive cleanup may erase the only persistent artifacts; the case needs recurrence prevention addressing whether remediation destroys evidence before acquisition; an investigation is not recurrence prevention.

Question 876

A technical closure review begins after this incident: An organization assumes a cloud provider will preserve every customer application log after a tenant account is compromised. After the immediate situation is stabilized, what addresses the enabling failure?

  1. Document customer-owned fixes and provider dependencies before service restoration
  2. Enable authorized export of existing tenant logs to protected storage
  3. Establish independent evidence collection and restore procedures for customer workloads
  4. Document shared-responsibility assignments in cloud incident playbooks

Explanation

Correct Answer

C:

Cloud operations cannot assume provider backups cover every investigation need; the affected workflow should not be considered trusted until the issue of which party is responsible for tenant-specific evidence retention is resolved.

Incorrect Answers

A:

Recovery plans should include both sides' obligations; the relevant condition for that step is which responsibility boundary controls remediation, which is not shown for which party is responsible for tenant-specific evidence retention.

B:

Immediate preservation reduces loss from service-specific retention limits; the requirement concerns which party is responsible for tenant-specific evidence retention, so temporary protection does not complete correction.

D:

Clear roles reduce response gaps across service boundaries; future hardening is not current-state recovery in the decision about which party is responsible for tenant-specific evidence retention.

Question 877

To avoid broad unnecessary disruption, responders consider this finding: An AWS account's central CloudTrail trail is stopped just before new IAM users appear. Which operational control should take effect first?

  1. Correlate StopLogging events with IAM user-creation activity and downstream archives
  2. Restore logging and restrict actors with trail-configuration permissions
  3. Remove unauthorized IAM identities and reconstruct actions during the gap
  4. Deactivate the exposed access key and restrict associated permissions

Explanation

Correct Answer

B:

Protection of the audit plane helps contain further concealment; the action limits the impact connected to whether audit tampering preceded unauthorized identities without assuming the underlying flaw is already gone.

Incorrect Answers

A:

Independent logging may preserve evidence of the attempt to suppress telemetry; when judging whether audit tampering preceded unauthorized identities, investigation alone does not control current conditions; this is instead evidence validation.

C:

Investigators should not assume the missing interval was benign; the requirement concerns whether audit tampering preceded unauthorized identities, so corrective follow-through follows initial protection.

D:

Credential containment prevents new cloud resources from being created; the relevant condition for that step is which record reconstructs cross-region API actions, which is not shown for whether audit tampering preceded unauthorized identities.

Question 878

The incident is resolved, but its root weakness still requires policy attention: An attacker modifies cloud object retention settings immediately before mass deletion of backup files. What durable process or monitoring change would make a repeat less likely?

  1. Compare retention-configuration audit events with deletion timestamps
  2. Use separate security accounts and tamper-resistant log storage
  3. Restore copies from independent protected repositories and reapply retention controls
  4. Use immutable backup design with independent administrative controls
  5. Restrict identities authorized to modify retention and stop deletion operations

Explanation

Correct Answer

D:

Protection should withstand compromise of ordinary workload identities; its effectiveness can be exercised against the warning conditions associated with whether backup immutability was weakened before destructive changes.

Incorrect Answers

A:

A settings change can remove a safeguard immediately before data loss; for whether backup immutability was weakened before destructive changes, an investigation is not recurrence prevention; recurrence prevention remains necessary.

B:

Administrative separation reduces attacker ability to hide traces; the relevant condition for that step is whether log tampering obscured follow-on actions, which is not shown for whether backup immutability was weakened before destructive changes.

C:

Recovery requires trusted data beyond the compromised policy scope; the goal is recurrence prevention for whether backup immutability was weakened before destructive changes. Case recovery is not future-risk control.

E:

Separating backup control from workload administration limits damage; the case needs recurrence prevention addressing whether backup immutability was weakened before destructive changes; one-time protection is not durable prevention.

Question 879

The initial scene or threat protection decision concerns the following: A suspicious virtual machine is about to be deleted by an autoscaling group after a failed health check. How should responders limit the damage while retaining the investigation trail?

  1. Snapshot relevant disks and preserve instance metadata before trusted replacement
  2. Build acquisition hooks into autoscaling and incident runbooks
  3. Disable or rotate the exposed key and constrain storage access
  4. Temporarily suspend the implicated termination workflow under incident authority
  5. Identify attached volumes, relevant runtime events and upcoming termination action

Explanation

Correct Answer

D:

A controlled hold creates an opportunity for acquisition; the protective decision should be recorded and its effect tested against whether termination will erase useful host evidence.

Incorrect Answers

A:

Investigation can continue from copies without retaining compromised production machines indefinitely; corrective follow-through follows initial protection in the decision about whether termination will erase useful host evidence.

B:

Automated preservation reduces loss from routine lifecycle events; the case needs initial containment or preservation addressing whether termination will erase useful host evidence; prevention cannot replace immediate action.

C:

Stopping credential replay limits continued downloads; it is meant to address whether API credentials were used for unauthorized reads, not initial containment or preservation for whether termination will erase useful host evidence.

E:

Ephemeral compute replacement can destroy disk state and local logs; the requirement concerns whether termination will erase useful host evidence, so investigation alone does not control current conditions.

Question 880

An improvement plan must address recurrence after this case: A Google Cloud VM may have uploaded data to the internet but investigators have only sparse firewall logs. What should the owner add to the normal control review to reduce recurrence?

  1. Enable appropriate flow logging and endpoint telemetry on sensitive workloads
  2. Capture persistent disk evidence and redeploy a verified instance
  3. Use least-privilege workload identities and admission checks
  4. Correlate available VPC Flow Logs with guest telemetry and audit activity

Explanation

Correct Answer

A:

Layered visibility improves attribution and scope; the ongoing control is targeted at where to find network and workload evidence, rather than a one-time emergency fix.

Incorrect Answers

B:

Clean compute restoration follows evidence preservation; the requirement concerns where to find network and workload evidence, so case recovery is not future-risk control.

C:

Deployment guardrails reduce overprivileged containers; the other incident centers on whether workload identity and authorization allowed the read, not this recurrence prevention question about where to find network and workload evidence.

D:

Network flows provide metadata and may need configuration before sufficient history exists; an investigation is not recurrence prevention in the decision about where to find network and workload evidence.
