ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 12

Question 110

A case commander must regain control of an open handling problem: The SOC calls every ATT&CK technique observed in logs a separate incident and loses the attack narrative. Which immediate assignment, safeguard or coordination decision is justified?

  1. Correlate technique observations by actor activity, time and affected assets
  2. Build a cohesive intrusion timeline with mapped ATT&CK techniques
  3. Commission a control effectiveness review rather than declaring compliance
  4. Group related detections into a single managed incident when supported by evidence

Explanation

Correct Answer

D:

Correlation improves coordinated containment and avoids fragmented response; the immediate coordination decision concerns how technique mapping relates to incident grouping; it keeps the response process under explicit control.

Incorrect Answers

A:

ATT&CK classifies behavior, while incident scope depends on connected events and impact; the requirement concerns how technique mapping relates to incident grouping, so investigation alone does not control current conditions.

B:

A technique map helps explain behavior without replacing incident evidence; the goal is immediate response coordination for how technique mapping relates to incident grouping. Corrective follow-through follows initial protection.

C:

Independent evaluation reveals untested steps before they are relied upon; that method could help with the gap between guidance adoption and operational evidence; the immediate response coordination decision here involves how technique mapping relates to incident grouping.

Question 111

An immediate process decision is needed for the following concern: A responder removes one malicious executable but leaves its service configuration and remote credentials active. What near-term response-governance action should be taken while the issue is open?

  1. Remove persistence, rotate compromised credentials and verify clean scanning
  2. Examine service configuration, scheduled starts and account-use records
  3. Halt destructive steps and secure remaining evidence with documented custody
  4. Disable malicious services and revoke affected secrets during controlled containment

Explanation

Correct Answer

D:

Blocking execution and access paths reduces the chance of immediate re-entry; the case needs an authorized near-term step for whether eradication removed the attack's persistence, with longer-term playbook changes handled separately.

Incorrect Answers

A:

Complete eradication addresses both malware artifacts and associated identity compromise; for whether eradication removed the attack's persistence, corrective follow-through follows initial protection; immediate response coordination remains necessary.

B:

Persistence and stolen credentials can sustain access after one file is deleted; the requirement concerns whether eradication removed the attack's persistence, so investigation alone does not control current conditions.

C:

Preservation protects evidentiary value while investigators assess what remains; the relevant condition for that step is why evidence collection must precede destructive remediation, which is not shown for whether eradication removed the attack's persistence.

Question 112

An incident-process audit asks for a defensible finding about this case: A service provider receives an alert but its contract lacks clear escalation and evidence-retention responsibilities. Which recorded evidence or practical test establishes the stated response-process issue?

  1. Search the ticket queue for an immutable case identifier and assignment history
  2. Compare contract clauses, contact trees and tested vendor response procedures
  3. Invoke emergency vendor contacts and establish a joint incident coordinator
  4. Include notification SLAs, evidence access and rehearsal requirements in agreements

Explanation

Correct Answer

B:

Missing duties can delay notification, collection and containment across boundaries; this provides an auditable basis for the disputed finding: whether third-party handoffs are executable.

Incorrect Answers

A:

Unstructured emails do not provide the consistent audit trail needed for response governance; this serves how incident recording supports traceability, whereas the requested result is process validation involving whether third-party handoffs are executable.

C:

Named decision makers enable immediate scope and evidence coordination; the case needs process validation addressing whether third-party handoffs are executable; immediate protection does not substantiate findings.

D:

Specific obligations reduce dependency ambiguity during incidents; when judging whether third-party handoffs are executable, prevention is not incident verification; this is instead readiness improvement.

Question 113

A case closure review must correct this incident-management failure: A restored server passes a boot test but its business transactions fail integrity checks. What is the appropriate procedural remediation for the gap described?

  1. Keep the server in a restricted validation segment until data integrity passes
  2. Reconcile all prior messages and artifacts into the case timeline
  3. Reconcile data, test dependent services and obtain application-owner acceptance
  4. Compare application transactions against known-good reconciliation results
  5. Add integrity checks and business-owner sign-off to restoration testing

Explanation

Correct Answer

C:

Recovery completes only when usable and trusted business functionality returns; the correction restores accountability or sequence for what recovery validation must include before case sign-off.

Incorrect Answers

A:

Controlled access prevents unreliable service from affecting production users; temporary protection does not complete correction in the decision about what recovery validation must include.

B:

A complete record prevents decisions and evidence references from being lost; this serves how incident recording supports traceability, whereas the requested result is procedural correction involving what recovery validation must include.

D:

Boot success does not prove that business data and dependent workflows remain correct; for what recovery validation must include, verification is not the corrective step; procedural correction remains necessary.

E:

A functional recovery gate catches failures missed by infrastructure checks; the requirement concerns what recovery validation must include, so future hardening is not current-state recovery.

Question 114

The response coordinator tests a weakness described in these records: A payroll server shows a new administrator login immediately before confidential reports appeared on an unknown share. What case-specific check would establish how this response procedure failed?

  1. Correlate privileged sign-in records with file-share audit events
  2. Alert on abnormal privileged logins followed by bulk file-share access
  3. Suspend the suspect privileged session while preserving its session identifiers
  4. Compare the alert with approved scanner inventory and change-window records

Explanation

Correct Answer

A:

The joined timeline can connect an identity, access to protected files, and the suspicious destination; that check tests whether a security event involved unauthorized access without assuming that a policy citation alone proves operational compliance.

Incorrect Answers

B:

A behavioral correlation catches the combined access pattern rather than either event alone; the requirement concerns whether a security event involved unauthorized access, so prevention is not incident verification.

C:

Revoking the active access path limits further disclosure without discarding the account activity already logged; the goal is process validation for whether a security event involved unauthorized access. Immediate protection does not substantiate findings.

D:

Authorized source and timing explain why the detection may be a benign true positive; that method could help with whether an alert is a confirmed incident; the process validation decision here involves whether a security event involved unauthorized access.

Question 115

A documented handling problem requires corrective follow-through: A containment change was implemented on an internet router without notifying the network duty officer and broke partner connectivity. What corrective record or operational change resolves this process weakness?

  1. Predefine emergency network-change authorities and rollback criteria
  2. Track detection and control fixes to evidence-backed completion
  3. Activate the emergency change coordination path and assess immediate rollback
  4. Validate the mitigation and partner connectivity before closing the change

Explanation

Correct Answer

D:

Both threat containment and service availability must be checked; the affected handling process should be validated against the control approval missing from the change after the change.

Incorrect Answers

A:

A tested authorization path prevents uncontrolled containment disruption; when judging the control approval missing from the change, future hardening is not current-state recovery; this is instead readiness improvement.

B:

Measured remediation converts the review into preventive change; it is meant to address what post-incident learning is missing, not procedural correction for the control approval missing from the change.

C:

Controlled action restores oversight while limiting further incident exposure; the requirement concerns the control approval missing from the change, so temporary protection does not complete correction.

Question 116

Response staff seek a controlled first step after this problem: A SOC manager assesses responder performance only by how quickly tickets are closed. Which immediate decision would restore control of the ongoing handling process?

  1. Sample fast-closed cases for evidence completeness and recurrence
  2. Appoint a cross-functional incident lead and merge correlated scope findings
  3. Introduce quality checks and track repeat compromise after closure
  4. Suspend automatic closure incentives during active high-impact investigations

Explanation

Correct Answer

D:

The incident outcome should drive decisions rather than a throughput target; the case needs an authorized near-term step for whether speed metrics reward poor incident decisions, with longer-term playbook changes handled separately.

Incorrect Answers

A:

Closure time alone cannot establish whether the attack was actually resolved; investigation alone does not control current conditions in the decision about whether speed metrics reward poor incident decisions.

B:

One coordinated response reduces contradictory containment measures; the relevant condition for that step is how to normalize severity across organizational units, which is not shown for whether speed metrics reward poor incident decisions.

C:

Outcome measures reveal cases prematurely marked resolved; when judging whether speed metrics reward poor incident decisions, corrective follow-through follows initial protection; this is instead procedural correction.

Question 117

A procedural case requires a near-term protective assignment: An organization has a CSF 2.0 profile but incorrectly claims it is a forensic evidence acquisition standard. Before long-term corrections, which authorized response action fits the current need?

  1. Examine the profile's Govern, Identify, Protect, Detect, Respond and Recover functions
  2. Maintain clear mappings between strategic frameworks and tactical procedures
  3. Flag the reference for governance correction without abandoning active response procedures
  4. Use a separate validated forensic procedure for evidence handling
  5. Map incident response capabilities to CSF functions and forensic SOPs

Explanation

Correct Answer

D:

Specific acquisition methods are still needed alongside strategic cybersecurity outcomes; the immediate coordination decision concerns what CSF 2.0 actually organizes; it keeps the response process under explicit control.

Incorrect Answers

A:

These risk-management outcomes do not prescribe bit-for-bit disk imaging procedures; the case needs immediate response coordination addressing what CSF 2.0 actually organizes; investigation alone does not control current conditions.

B:

Document clarity prevents responders from expecting nonexistent implementation instructions; when judging what CSF 2.0 actually organizes, prevention cannot replace immediate action; this is instead readiness improvement.

C:

A citation update must not interrupt evidence preservation during a live incident; the relevant condition for that step is whether cited incident-response guidance is current, which is not shown for what CSF 2.0 actually organizes.

E:

Complementary guidance avoids treating a framework as a detailed tool runbook; the goal is immediate response coordination for what CSF 2.0 actually organizes. Corrective follow-through follows initial protection.

Question 118

The response coordinator tests a weakness described in these records: A triage analyst has only an IP address from an old NAT gateway log and assigns the incident to the wrong user. What case-specific check would establish how this response procedure failed?

  1. Correct the case attribution and document uncertain mappings
  2. Pause individual account sanctions until attribution is independently validated
  3. Correlate source port, timestamp, NAT translation and identity session records
  4. Compare the incident change ticket with the designated approval and escalation matrix
  5. Compare deletion times with evidence acquisition records and case directives
  6. Retain synchronized NAT, DHCP and authentication logs at adequate granularity

Explanation

Correct Answer

C:

Shared addresses cannot identify a unique user without translation and timing context; that check tests how to attribute network activity reliably without assuming that a policy citation alone proves operational compliance.

Incorrect Answers

A:

Traceable assumptions keep an investigation from building on false identity claims; for how to attribute network activity reliably, recovery is not factual verification; process validation remains necessary.

B:

Evidence-based escalation avoids disrupting an innocent user's access; the requirement concerns how to attribute network activity reliably, so immediate protection does not substantiate findings.

D:

The record shows whether emergency authority and network coordination were followed; the other incident centers on the control approval missing from the change, not this process validation question about how to attribute network activity reliably.

E:

The timeline can show that potentially relevant bytes were removed before a verified image; this serves why evidence collection must precede destructive remediation, whereas the requested result is process validation involving how to attribute network activity reliably.

F:

Correlated records make future attribution defensible; when judging how to attribute network activity reliably, prevention is not incident verification; this is instead readiness improvement.

Question 119

An immediate process decision is needed for the following concern: An orchestration playbook automatically isolates every host with a single low-confidence malware alert. What response coordination or restriction step should take priority?

  1. Trigger an approved indicator-distribution playbook from the correlated alert
  2. Test revised triggers against representative benign and malicious alerts
  3. Use risk-based automation tiers and rollback controls
  4. Require analyst approval before high-impact isolation on ambiguous alerts
  5. Review the playbook trigger thresholds and isolation execution logs

Explanation

Correct Answer

D:

A human gate limits business disruption while preserving rapid automated evidence gathering; this protective or assignment decision directly addresses the risk of excessive automated containment while response governance is still active.

Incorrect Answers

A:

Automated propagation shortens the delay while maintaining change records; it is meant to address where manual coordination delays indicator response, not immediate response coordination for the risk of excessive automated containment.

B:

Simulation checks that the updated workflow reduces false containment; corrective follow-through follows initial protection in the decision about the risk of excessive automated containment.

C:

Different thresholds for enrichment and disruptive action make orchestration safer; the case needs immediate response coordination addressing the risk of excessive automated containment; prevention cannot replace immediate action.

E:

Comparing alert confidence to actions shows whether automation exceeded agreed risk tolerance; for the risk of excessive automated containment, investigation alone does not control current conditions; immediate response coordination remains necessary.

Question 120

After technical restoration, responders document the weakness exposed by: An alert involving payment-card data was categorized low because only one host was affected. Which long-term control would reduce exposure to this specific pattern?

  1. Publish severity definitions with worked examples and training
  2. Reassess scope and record the corrected severity and response deadlines
  3. Include data sensitivity and regulatory triggers in triage scoring
  4. Review affected data classification together with host criticality and exposure

Explanation

Correct Answer

C:

Impact criteria prevent host-count-only severity mistakes; this turns the weakness behind whether incident priority reflects business impact into a measurable prevention requirement.

Incorrect Answers

A:

Common interpretation reduces repeated classification disputes; this serves how to normalize severity across organizational units, whereas the requested result is readiness improvement involving whether incident priority reflects business impact.

B:

An impact-driven case update fixes the prioritization error before closure; the case needs readiness improvement addressing whether incident priority reflects business impact; case recovery is not future-risk control.

D:

Business sensitivity can outweigh the number of visibly impacted machines; for whether incident priority reflects business impact, an investigation is not recurrence prevention; readiness improvement remains necessary.
