Isaca CISM Practice Test 48

Question 470

New analysts know detection tools but not who can approve quarantining a business-critical server. Which decision is BEST supported by the business and security evidence?

  1. Coach evidence logging and rehearse documentation as part of exercises.
  2. Train responders on decision authority, escalation and business-impact criteria.
  3. Train qualified alternates and test succession for each critical response role.
  4. Conduct cross-regional exercises that include legal escalation and local notification duties.

Explanation

Correct Answer

B:

Technical competency must be paired with governance knowledge for safe containment. This directly meets the requirement to train on high-impact response approvals.

Incorrect Answers

A:

Reliable incident records require practiced behavior under time pressure. That action would improve incident documentation skills; it does not address the case's priority to train on high-impact response approvals.

C:

Response continuity requires coverage when designated personnel are absent. This would help avoid single-person response dependency; the scenario instead requires a decision to train on high-impact response approvals.

D:

Geographic response effectiveness depends on understanding jurisdictional coordination. That action would train global incident response handoffs; it does not address the case's priority to train on high-impact response approvals.

Question 471

A recovery exercise proves a single server restores but not whether dependent applications are usable. What is the MOST appropriate next action for the information security manager?

  1. Record detection and response timing against predefined objectives for comparison.
  2. Use synthetic evidence and controlled exercise infrastructure with authorized boundaries.
  3. Test end-to-end business service restoration and dependency validation.
  4. Establish controlled scope, safety safeguards and approval before execution.

Explanation

Correct Answer

C:

A component being online does not prove that customers can use the service. This directly meets the requirement to verify service-level restoration in exercises.

Incorrect Answers

A:

A baseline makes subsequent capability improvement observable. That action would quantify incident simulation response timeliness; it does not address the case's priority to verify service-level restoration in exercises.

B:

Training simulations should not create the compromise they are intended to prevent. It is primarily relevant when the need is to prevent exercise-induced data disclosure, rather than to verify service-level restoration in exercises.

D:

High-impact testing must avoid creating unacceptable service risks. That action would safely scope live-system incident exercises; it does not address the case's priority to verify service-level restoration in exercises.

Question 472

Repeated incident drills show slow decisions but no leadership review is conducted. Which management response BEST addresses the stated risk or governance priority?

  1. Run a targeted cross-party exercise and update arrangements based on results.
  2. Benchmark response processes, capability coverage and outcomes against comparable criteria.
  3. Evaluate actual readiness using exercises, evidence of capability and unresolved improvement actions.
  4. Escalate measured exercise gaps and obtain funded corrective-action ownership.

Explanation

Correct Answer

D:

Governance must use practice evidence to strengthen capability rather than archive findings. This directly meets the requirement to secure accountable incident readiness improvements.

Incorrect Answers

A:

Supplier obligations need evidence of practical execution under realistic timing. That action would validate outsourced incident notification readiness; it does not address the case's priority to secure accountable incident readiness improvements.

B:

Incident counts depend on exposure and detection, not simply maturity. It is primarily relevant when the need is to benchmark incident capability fairly, rather than to secure accountable incident readiness improvements.

C:

A plan's existence cannot demonstrate that teams will perform it effectively. This would help assess operational incident readiness; the scenario instead requires a decision to secure accountable incident readiness improvements.

Question 473

Security monitoring produces events but no one can differentiate a policy violation from an actual incident. Which management action BEST meets the stated requirement?

  1. Define documented incident criteria combining evidence, impact and response thresholds.
  2. Use a provisional classification and time-bound triage with clear escalation triggers.
  3. Standardize enterprise severity definitions and examples across responding teams.
  4. Evaluate scope and business impact before final severity designation.

Explanation

Correct Answer

A:

Classification separates routine events from cases requiring coordinated intervention. This directly meets the requirement to distinguish events from declared incidents.

Incorrect Answers

B:

Uncertainty should prompt structured investigation rather than dismissal or unfounded certainty. It is primarily relevant when the need is to classify uncertain high-impact security events, rather than to distinguish events from declared incidents.

C:

Consistent categories improve escalation, metrics and resource allocation. This would help standardize incident severity terminology; the scenario instead requires a decision to distinguish events from declared incidents.

D:

Early reports may understate a rapidly expanding incident. That action would avoid premature low-severity incident classification; it does not address the case's priority to distinguish events from declared incidents.

Question 474

A simulated phishing drill risks sending real customer information to an external testing site. Which decision is BEST supported by the business and security evidence?

  1. Record detection and response timing against predefined objectives for comparison.
  2. Use synthetic evidence and controlled exercise infrastructure with authorized boundaries.
  3. Establish controlled scope, safety safeguards and approval before execution.
  4. Test end-to-end business service restoration and dependency validation.

Explanation

Correct Answer

B:

Training simulations should not create the compromise they are intended to prevent. This directly meets the requirement to prevent exercise-induced data disclosure.

Incorrect Answers

A:

A baseline makes subsequent capability improvement observable. That action would quantify incident simulation response timeliness; it does not address the case's priority to prevent exercise-induced data disclosure.

C:

High-impact testing must avoid creating unacceptable service risks. This would help safely scope live-system incident exercises; the scenario instead requires a decision to prevent exercise-induced data disclosure.

D:

A component being online does not prove that customers can use the service. That action would verify service-level restoration in exercises; it does not address the case's priority to prevent exercise-induced data disclosure.

Question 475

Employees learn about ransomware from news because internal briefings are not assigned. What is the MOST appropriate next action for the information security manager?

  1. Establish secure alternate communication channels and test their availability.
  2. Define authorized public spokesperson and approval process for verified statements.
  3. Define internal stakeholder cadence, message owner and update triggers.
  4. Maintain a jurisdiction-aware notification matrix and responsible legal decision makers.

Explanation

Correct Answer

C:

Reliable internal communication reduces rumor and supports coordinated business action. This directly meets the requirement to plan timely workforce incident updates.

Incorrect Answers

A:

Compromised or unavailable primary systems must not prevent coordination. That action would preserve crisis communication during email compromise; it does not address the case's priority to plan timely workforce incident updates.

B:

Crisis communications must be accurate, coordinated and legally appropriate. It is primarily relevant when the need is to control public incident messaging, rather than to plan timely workforce incident updates.

D:

Reporting duties vary with incident type, location and affected data. That action would prepare for varied regulatory notification deadlines; it does not address the case's priority to plan timely workforce incident updates.

Question 476

The incident bridge has no backup internet or independent contact roster. Which management response BEST addresses the stated risk or governance priority?

  1. Prearrange scoped emergency roles and tested access to required evidence sources.
  2. Define surge staffing, external assistance and rotation plans for prolonged incidents.
  3. Stage essential equipment and establish vendor emergency supply arrangements.
  4. Establish resilient coordination channels and offline contact information.

Explanation

Correct Answer

D:

Crisis teams need reliable command communication when normal systems fail. This directly meets the requirement to make crisis mobilization resilient.

Incorrect Answers

A:

Missing permissions can delay investigation even with skilled responders. That action would ensure incident evidence access readiness; it does not address the case's priority to make crisis mobilization resilient.

B:

Extended crises exhaust normal staffing unless capability can expand. It is primarily relevant when the need is to prepare sufficient incident response surge capacity, rather than to make crisis mobilization resilient.

C:

Response plans depend on available physical and technical resources. This would help assure incident response equipment availability; the scenario instead requires a decision to make crisis mobilization resilient.

Question 477

An incident communication plan assumes corporate email will remain available during a mailbox attack. Which management action BEST meets the stated requirement?

  1. Establish secure alternate communication channels and test their availability.
  2. Maintain a jurisdiction-aware notification matrix and responsible legal decision makers.
  3. Define internal stakeholder cadence, message owner and update triggers.
  4. Define authorized public spokesperson and approval process for verified statements.

Explanation

Correct Answer

A:

Compromised or unavailable primary systems must not prevent coordination. This directly meets the requirement to preserve crisis communication during email compromise.

Incorrect Answers

B:

Reporting duties vary with incident type, location and affected data. It is primarily relevant when the need is to prepare for varied regulatory notification deadlines, rather than to preserve crisis communication during email compromise.

C:

Reliable internal communication reduces rumor and supports coordinated business action. This would help plan timely workforce incident updates; the scenario instead requires a decision to preserve crisis communication during email compromise.

D:

Crisis communications must be accurate, coordinated and legally appropriate. That action would control public incident messaging; it does not address the case's priority to preserve crisis communication during email compromise.

Question 478

A security analyst is authorized to block accounts but not to disconnect a life-sustaining system. Which decision is BEST supported by the business and security evidence?

  1. Design deputies and tested after-hours succession for incident leadership.
  2. Define safety-sensitive action approvals and business continuity escalation.
  3. Establish an incident command hierarchy and delegated decisions for high-impact actions.
  4. Create an incident role matrix including technical, legal and communications responsibilities.

Explanation

Correct Answer

B:

Some containment decisions require authority beyond routine technical response. This directly meets the requirement to govern high-impact containment authority.

Incorrect Answers

A:

Response must continue when designated personnel are absent. That action would maintain incident command availability; it does not address the case's priority to govern high-impact containment authority.

C:

Unified command resolves competing directions in time-critical situations. This would help prevent conflicting crisis containment orders; the scenario instead requires a decision to govern high-impact containment authority.

D:

Defined duties reduce omissions and unclear handoffs. That action would assign complete incident response responsibilities; it does not address the case's priority to govern high-impact containment authority.
