Q361. Which financial measure shows how much profit remains after variable costs

1. Contribution margin
2. Current ratio
3. Debt ratio
4. Asset turnover

Correct Answer: 1. Contribution margin

Explanation

Contribution margin represents sales revenue remaining after variable costs are deducted. The amount contributes toward covering fixed costs and then generating operating profit. Current ratio measures short term liquidity. Debt ratio measures financial leverage. Asset turnover measures how efficiently assets generate revenue. Contribution margin is therefore the correct answer because it helps management understand how changes in sales volume affect profitability. It is commonly used in break even analysis pricing decisions product evaluations and short term operational decisions where management needs to understand the incremental financial effect of additional sales.

Q362. Which security control protects information by converting it into unreadable form

1. Data archiving
2. Encryption
3. Capacity planning
4. File indexing

Correct Answer: 2. Encryption

Explanation

Encryption protects information by transforming readable data into an unreadable form that requires the correct key for access. It can protect data while stored and while transmitted across networks. Data archiving manages long term information retention. Capacity planning estimates future technology resource needs. File indexing improves information retrieval. Encryption is therefore the correct answer because its primary purpose is confidentiality. Organizations should also manage encryption keys securely because weak key management can undermine otherwise strong encryption controls and potentially prevent authorized users from accessing important information when needed.

Q363. Which audit analytics technique tests every transaction in a selected data set

1. Judgmental sampling
2. Random sampling
3. Full population analysis
4. Systematic sampling

Correct Answer: 3. Full population analysis

Explanation

Full population analysis examines every transaction or record in the selected data set rather than testing only a sample. Modern analytics tools can make this approach practical for large transaction populations. Judgmental sampling selects items based on auditor judgment. Random sampling uses probability. Systematic sampling selects items using a defined interval. Full population analysis is therefore the correct answer because it provides broad coverage and can identify unusual items that might not appear in a smaller sample. Auditors still need professional judgment when setting tests and evaluating exceptions identified through the analysis.

Q364. Which project document records who is responsible for major project tasks

1. Gantt chart
2. Risk register
3. Cost baseline
4. Responsibility matrix

Correct Answer: 4. Responsibility matrix

Explanation

A responsibility matrix assigns project responsibilities to individuals or groups and helps clarify who performs approves supports or receives information about important activities. A Gantt chart shows project timing. A risk register records risks and responses. A cost baseline establishes approved project spending. Responsibility matrix is therefore the correct answer because it focuses directly on accountability and task ownership. Clear responsibility reduces confusion and helps prevent important activities from being missed because team members assume another person is responsible for completing or approving the work.

Q365. Which economic measure reflects a general increase in consumer prices

1. Inflation rate
2. Productivity rate
3. Unemployment rate
4. Exchange volume

Correct Answer: 1. Inflation rate

Explanation

Inflation rate measures the pace at which the general price level increases over time. Rising inflation reduces the purchasing power of money and can affect wages interest rates purchasing decisions budgets and investment plans. Productivity rate measures output relative to inputs. Unemployment rate measures labor market conditions. Exchange volume is not the standard measure described. Inflation rate is therefore the correct answer because it specifically reflects broad price increases across the economy. Management should consider inflation when forecasting costs pricing products and evaluating long term financial plans.

Q366. Which control best reduces the risk of duplicate customer refunds

1. File compression
2. Duplicate refund check
3. Data backup
4. Network routing

Correct Answer: 2. Duplicate refund check

Explanation

A duplicate refund check compares customer refund transactions using information such as customer number amount invoice number return number and date. This can identify repeated refunds before or after processing. File compression reduces storage requirements. Data backup supports recovery. Network routing directs communication traffic. Duplicate refund check is therefore the correct answer because it directly targets the risk that the same return or adjustment is refunded more than once. Organizations may also use authorization limits segregation of duties and periodic analytics to strengthen controls over customer refunds.

Q367. Which organizational concept describes the formal chain of authority

1. Corporate culture
2. Job rotation
3. Chain of command
4. Empowerment

Correct Answer: 3. Chain of command

Explanation

Chain of command describes the formal line of authority from higher management levels to lower levels within an organization. It helps employees understand who has authority to make decisions and to whom they report. Corporate culture reflects shared values and behaviors. Job rotation moves employees among different assignments. Empowerment gives employees greater decision authority within defined limits. Chain of command is therefore the correct answer because it specifically describes formal reporting and authority relationships. A clear chain can improve accountability although overly rigid structures may sometimes reduce flexibility and communication speed.

Q368. Which security principle requires proof that a user is who they claim to be

1. Availability
2. Confidentiality
3. Integrity
4. Authentication

Correct Answer: 4. Authentication

Explanation

Authentication verifies the identity of a user device or system before access is granted. Common methods include passwords security tokens biometrics and multifactor techniques. Availability ensures resources remain accessible. Confidentiality protects information from unauthorized disclosure. Integrity protects information from unauthorized modification. Authentication is therefore the correct answer because it establishes whether the requesting party is actually the identity being presented. Strong authentication is an important foundation for access control because authorization decisions are useful only when the identity of the user has been verified reliably.

Q369. Which ratio compares current assets excluding inventory with current liabilities

1. Quick ratio
2. Debt ratio
3. Gross margin
4. Return on equity

Correct Answer: 1. Quick ratio

Explanation

The quick ratio measures short term liquidity using highly liquid current assets and normally excludes inventory because inventory may require more time to convert into cash. Debt ratio measures leverage. Gross margin measures profitability after cost of goods sold. Return on equity compares profit with owners equity. Quick ratio is therefore the correct answer because it provides a more conservative view of short term payment ability than the current ratio. Analysts often use it when inventory is relatively slow moving or when they want to focus on assets more readily available to meet current obligations.

Q370. Which process evaluates whether controls remain effective after a major system change

1. File archiving
2. Post implementation review
3. Data compression
4. Capacity planning

Correct Answer: 2. Post implementation review

Explanation

A post implementation review evaluates whether a completed system change or project achieved expected objectives and whether related controls operate effectively after deployment. It can identify unresolved issues weaknesses benefits and lessons learned. File archiving manages retained information. Data compression reduces storage size. Capacity planning estimates future resource demand. Post implementation review is therefore the correct answer because significant changes can introduce new risks even when implementation appears successful. Management and internal audit can use the review results to identify corrective actions and improve future change processes.

Q371. Which market force increases when customers have many alternative suppliers

1. Supplier power
2. Entry barrier
3. Buyer power
4. Fixed cost

Correct Answer: 3. Buyer power

Explanation

Buyer power increases when customers have many supplier choices low switching costs or significant purchasing volume. Strong buyer power can pressure sellers to reduce prices improve quality or provide better service. Supplier power concerns the influence vendors have over buyers. Entry barriers affect how easily new competitors enter a market. Fixed cost is a cost behavior concept. Buyer power is therefore the correct answer because customers with many alternatives can negotiate more effectively and can switch providers if they are dissatisfied with price quality or service.

Q372. Which control best helps ensure only approved software changes reach production

1. Data backup
2. Password aging
3. File compression
4. Formal change approval

Correct Answer: 4. Formal change approval

Explanation

Formal change approval requires authorized review before software modifications are moved into production. This helps prevent unauthorized or poorly considered changes from affecting live systems. Data backup supports recovery. Password aging changes credentials periodically. File compression reduces storage requirements. Formal change approval is therefore the correct answer because production systems should be protected by a structured change process. Effective change management also includes testing documentation segregation between development and production and post implementation review for significant changes that could affect business operations or security.

Q373. Which budget variance occurs when actual sales volume differs from planned volume

1. Volume variance
2. Rate variance
3. Price variance
4. Efficiency variance

Correct Answer: 1. Volume variance

Explanation

Volume variance arises when the actual quantity of activity or sales differs from the amount expected in the budget or standard. Rate variance generally relates to differences in cost or pay rates. Price variance relates to the difference between actual and expected purchase or selling prices. Efficiency variance often compares actual input usage with standard input usage. Volume variance is therefore the correct answer because it isolates the financial effect associated with changes in activity quantity. Management can analyze the cause to determine whether market demand capacity or other factors influenced results.

Q374. Which business continuity measure identifies the maximum acceptable time a system may be unavailable

1. RPO
2. RTO
3. ROI
4. TCO

Correct Answer: 2. RTO

Explanation

RTO defines the target maximum time allowed to restore a system or process after disruption. RPO defines acceptable data loss measured by time. ROI evaluates investment return. TCO evaluates total lifecycle cost. RTO is therefore the correct answer because it directly addresses how quickly operations must resume. More demanding recovery time objectives usually require greater investment in resilient infrastructure automation recovery sites and tested procedures. Management should set the objective based on business impact rather than technical preference alone.

Q375. Which audit procedure checks mathematical accuracy of a client calculation

1. Inquiry
2. Observation
3. Recalculation
4. Confirmation

Correct Answer: 3. Recalculation

Explanation

Recalculation involves independently checking the mathematical accuracy of calculations prepared by management or employees. It can be used for depreciation interest payroll totals inventory extensions and other computations. Inquiry obtains information through questions. Observation involves watching procedures. Confirmation obtains evidence from an external party. Recalculation is therefore the correct answer because the auditor personally verifies the arithmetic or computational result. The procedure provides evidence about accuracy but does not by itself establish whether the assumptions or source information used in the calculation are appropriate.

Q376. Which organizational practice best preserves knowledge when experienced employees retire

1. Downsizing
2. Centralization
3. Outsourcing
4. Knowledge transfer

Correct Answer: 4. Knowledge transfer

Explanation

Knowledge transfer captures and shares important skills processes experience and institutional knowledge before key employees leave the organization. Downsizing reduces organizational size. Centralization concentrates authority. Outsourcing transfers activities to external providers. Knowledge transfer is therefore the correct answer because valuable operational knowledge can otherwise disappear when experienced employees retire or resign. Organizations can use documentation mentoring cross training job shadowing and structured handover activities to reduce dependence on individuals and maintain continuity of important processes.

Q377. Which financial measure compares revenue with average total assets

1. Asset turnover
2. Current ratio
3. Debt ratio
4. Net margin

Correct Answer: 1. Asset turnover

Explanation

Asset turnover compares revenue with average total assets and measures how efficiently the organization uses its asset base to generate sales. Current ratio measures liquidity. Debt ratio measures leverage. Net margin measures profitability relative to revenue. Asset turnover is therefore the correct answer because it focuses on operating efficiency associated with assets. A declining ratio can indicate underused assets weak sales or significant investment that has not yet produced expected revenue. Industry characteristics should be considered because asset intensity varies significantly across different types of businesses.

Q378. Which control helps prevent unauthorized disclosure through removable storage devices

1. File indexing
2. Device control
3. Data normalization
4. Capacity planning

Correct Answer: 2. Device control

Explanation

Device control restricts or monitors the use of removable media such as external drives and portable storage devices. This can reduce the risk of sensitive information being copied without authorization or malicious software entering the environment. File indexing improves search performance. Data normalization organizes database structures. Capacity planning estimates future resource needs. Device control is therefore the correct answer because removable media can bypass normal network security boundaries. Strong controls may include encryption approved device lists logging and disabling removable storage when business use is not required.

Q379. Which strategic analysis evaluates strengths weaknesses opportunities and threats

1. Ratio analysis
2. Trend analysis
3. SWOT analysis
4. Break even analysis

Correct Answer: 3. SWOT analysis

Explanation

SWOT analysis evaluates internal strengths and weaknesses together with external opportunities and threats. Ratio analysis evaluates relationships among financial measures. Trend analysis examines changes over time. Break even analysis identifies the sales level at which revenue equals total cost. SWOT analysis is therefore the correct answer because it provides a structured strategic view of both internal capabilities and external conditions. Management can use the results to identify areas of competitive advantage weaknesses needing improvement and external developments that may support or threaten organizational objectives.

Q380. Which governance practice best strengthens independence of internal audit leadership

1. Reporting only to finance management
2. Management approval of every audit conclusion
3. Limiting board communication
4. Functional reporting to the audit committee

Correct Answer: 4. Functional reporting to the audit committee

Explanation

Functional reporting to the audit committee strengthens internal audit independence by giving the chief audit executive direct access to the body responsible for oversight. Reporting only to finance management could create conflicts. Requiring management approval of audit conclusions undermines objectivity. Limiting board communication weakens governance. Functional reporting to the audit committee is therefore the correct answer because the committee can approve the internal audit charter plan resources and significant communications while management may still provide appropriate administrative support. This structure helps protect internal audit from inappropriate operational influence.
