Question 470

Management reports that this issue has been corrected: A payment service uses a load balancer, two application servers and one database but its diagram lists only the web servers as critical. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Conflicting updates resolve consistently with an auditable business rule.
  2. An end-to-end fault analysis covers each critical dependency and its recovery plan.
  3. A realistic stress test meets response targets with required failover headroom.
  4. Representative warehouse transactions continue correctly after the planned router change.

Explanation

Correct Answer

B:

An end-to-end fault analysis covers each critical dependency and its recovery plan. It addresses it components. Underlying audit concern: End-to-end service availability depends on all critical infrastructure and application components.

Incorrect Answers

A:

Conflicting updates resolve consistently with an auditable business rule. This would be relevant to a different issue such as: Two systems independently update the same customer address, producing unpredictable last-write results. In the present case, the most directly relevant verification is: An end-to-end fault analysis covers each critical dependency and its recovery plan. The governing distinction is: End-to-end service availability depends on all critical infrastructure and application components.

C:

A realistic stress test meets response targets with required failover headroom.

  1. Active licenses, contract costs and actual deployments agree within documented exceptions.
  2. A measured peak-like exercise meets agreed recovery times and identifies capacity shortfalls.
  3. Safety-critical services receive priority proportionate to validated harm.
  4. A recovery test completes reconciled business transactions within required limits.

Explanation

Correct Answer

B:

A measured peak-like exercise meets agreed recovery times and identifies capacity shortfalls. It addresses disaster recovery plans. Underlying audit concern: DR readiness should be tested under credible operational demand and resource constraints.

Incorrect Answers

A:

Active licenses, contract costs and actual deployments agree within documented exceptions.

Question 472

An IS auditor evaluates this situation: An audit query joins employee and privilege tables but mistakenly duplicates rows for users with multiple roles. Which audit principle MOST directly applies to this situation?

  1. A zero-exception result is unreliable if data completeness and pipeline health are unverified.
  2. Remediation after the audit period does not retroactively prove the control operated during that period.
  3. Join multiplicity can distort counts and audit conclusions even when query syntax succeeds.
  4. Risk-based audit planning is dynamic when business context and material exposures change.

Explanation

Correct Answer

C:

Join multiplicity can distort counts and audit conclusions even when query syntax succeeds. The corresponding audit procedure is: Reconcile unique user IDs, row counts and cardinality before and after joins.

Incorrect Answers

A:

A zero-exception result is unreliable if data completeness and pipeline health are unverified.
