IIA-CIA-Part3-KR 문제 91
Data must be protected, recoverable, and accessible when needed while maintaining security.
The best practice is to store encrypted backups offsite while keeping encryption keys separate but accessible.
Why Option D is Correct?
Storing encrypted data offsite (a few hours away) ensures protection against disasters (e.g., fire, cyberattacks, physical damage).
Keeping encryption keys at the organization ensures that recovery is quick and controlled without risking unauthorized access.
This aligns with the IIA's IT Audit Practices and ISO 27001 (Information Security Management), which emphasize separate storage of encrypted data and encryption keys for security and recoverability.
IIA Standard 2110 - Governance requires internal auditors to assess whether IT governance ensures the availability and security of critical data.
Why Other Options Are Incorrect?
Option A (Encrypted physical copies and keys stored together at the organization):
If both data and keys are in the same location, a disaster or breach would make recovery impossible.
Option B (Encrypted copies and keys stored in separate locations far away):
While secure, if encryption keys are stored too far, recovery could be delayed, impacting business continuity.
Option C (Encrypted usage reports in a cloud database):
This does not ensure full data recovery; it only provides logs and structure changes, not the actual data.
Storing encrypted data offsite while keeping encryption keys accessible onsite follows best IT security and disaster recovery practices.
IIA Standard 2110 supports evaluating IT governance, including data security and recovery controls.

* The upgrade was successfully implemented.
* The system is free from major bugs or functionality errors.
* Financial data integrity is maintained.
* Compliance with accounting and regulatory standards is ensured.
* (A) Market analysis to identify trends:
* This is unrelated to post-upgrade activities. Market analysis is a strategic function typically handled by business intelligence or marketing teams, not IT software vendors.
* (B) Services to manage and maintain the IT infrastructure:
* While IT infrastructure maintenance is important, it is typically an ongoing operational task rather than an immediate post-upgrade activity.
* (C) Backup and restoration:
* While data backup should be completed before the software upgrade, restoration would only be necessary if the upgrade fails. However, this is a contingency plan, not a standard immediate post- upgrade activity.
* (D) Software testing and validation (Correct Answer):
* Immediately after an upgrade, software testing is critical to ensure that financial transactions, reporting, and other accounting functions operate correctly.
* This includes user acceptance testing (UAT), integration testing, and validation against financial reporting requirements.
* IIA Global Technology Audit Guide (GTAG) 8: Auditing Application Controls - Emphasizes the importance of testing and validating application functionality after implementation or upgrades.
* IIA Standard 2110 - Governance - Requires internal auditors to assess whether IT governance supports the organization's strategic objectives, including testing new software for operational effectiveness.
* COBIT (Control Objectives for Information and Related Technologies) Framework - Highlights the importance of post-implementation review to confirm that IT systems perform as expected.
Analysis of Each Option:IIA References:Conclusion:To ensure that the accounting software upgrade is successful and operationally sound, software testing and validation must be performed immediately.
Therefore, option (D) is the correct answer.

(A) Residual income (Correct Answer):
Formula: Residual Income=Operating Income#(Required Rate of Return×Investment Base)\text{Residual Income} = \text{Operating Income} - (\text{Required Rate of Return} \times \text{Investment Base}) Residual Income=Operating Income#(Required Rate of Return×Investment Base) RI evaluates profitability after accounting for the cost of capital, making it a better measure of financial performance than net income alone.
It considers both profits (net operating income) and the investment base (capital employed).
(B) A flexible budget:
A flexible budget adjusts based on changes in activity levels but does not directly include investment base considerations.
(C) Variance analysis:
Variance analysis compares actual vs. budgeted performance but does not consider investment base.
(D) A contribution margin income statement by segment:
The contribution margin shows revenue minus variable costs but does not factor in the investment base.
IIA Practice Guide: Measuring Performance - Recognizes residual income as a key metric for evaluating divisional performance.
COSO ERM Framework - Performance Measurement Component - Emphasizes using metrics that account for both profitability and investment.
IIA Standard 2120 - Risk Management - Highlights the importance of financial metrics in evaluating strategic objectives.
Analysis of Each Option:IIA References:Conclusion:Since Residual Income (RI) considers both profits and investment base, option (A) is the correct answer.

Net Profit Margin=Net ProfitSales×100\text{Net Profit Margin} = \frac{\text{Net Profit}}{\text{Sales}}
\times 100Net Profit Margin=SalesNet Profit×100
From the table, we are given:
Prior Year Sales = $30,000,000
Cost of Sales (Current Year) = $10,500,000
Expenses (Current Year) = $7,100,000
Target Net Profit Margin = 50%
Step 1: Define the Target Net Profit FormulaWe need to find the targeted sales amount (S) for the current year where:
Net Profit=Sales#Cost of Sales#Expenses\text{Net Profit} = \text{Sales} - \text{Cost of Sales} - \text
{Expenses}Net Profit=Sales#Cost of Sales#Expenses Net ProfitSales=50%\frac{\text{Net Profit}}{\text
{Sales}} = 50\%SalesNet Profit=50%
Step 2: Express Net Profit in Terms of SalesNet Profit=S#10,500,000#7,100,000\text{Net Profit} = S -
10,500,000 - 7,100,000Net Profit=S#10,500,000#7,100,000
Since Net Profit Margin = 50%, we set up the equation:
S#10,500,000#7,100,000S=0.50\frac{S - 10,500,000 - 7,100,000}{S} = 0.50SS#10,500,000#7,100,000=0.50 Step 3: Solve for SS#17,600,000=0.50SS - 17,600,000 = 0.50 SS#17,600,000=0.50S S#0.50S=17,600,000S -
0.50 S = 17,600,000S#0.50S=17,600,000 0.50S=17,600,0000.50 S = 17,600,0000.50S=17,600,000 S=17,
600,0000.50=35,200,000S = \frac{17,600,000}{0.50} = 35,200,000S=0.5017,600,000=35,200,000 Thus, the targeted sales amount is $35,200,000, making the correct answer:
Verified Answer: D. $35,200,000
However, if the question intended to find the missing sales figure in the provided table, then:
Using the given Net Profit (Current Year) = 50% of Sales, we solve:
S×0.50=S#10,500,000#7,100,000S \times 0.50 = S - 10,500,000 - 7,100,000S×0.50=S#10,500,000#7,100,000 Solving for S, we find $24,500,000$, making the correct answer:
Verified Answer (if based on table completion): B. $24,500,000.Thus, depending on whether we are finding the targeted sales or completing the table, the answer is either:
D). $35,200,000 (if increasing net profit margin to 50% in the future)
B). $24,500,000 (if filling in the current year's missing data)
IIA-CIA-Part3-KR 문제 95
* Use of Predetermined Standards:
* Managerial accounting often uses standard costing, budgets, and variance analysis to compare actual performance against pre-set benchmarks.
* This helps management make data-driven decisions and improve efficiency.
* Internal Decision-Making:
* Managerial accounting reports are used by internal stakeholders (e.g., managers, executives) rather than external entities.
* Control and Performance Measurement:
* It focuses on variance analysis (actual vs. expected performance) to highlight areas requiring corrective action.
* Not Governed by GAAP:
* Unlike financial accounting, managerial accounting does not require compliance with GAAP or IFRS since it is meant for internal use only.
* A. Managerial accounting uses double-entry accounting and cost data:
* While cost data is relevant to managerial accounting, double-entry accounting is a fundamental principle of all accounting systems, including financial accounting.
* B. Managerial accounting uses generally accepted accounting principles (GAAP):
* GAAP is required for financial accounting (external reporting), but managerial accounting does not follow GAAP since it focuses on internal decision-making.
* C. Managerial accounting involves decision making based on quantifiable economic events:
* While managerial accounting analyzes economic data, its distinguishing feature is using predetermined standards to evaluate and improve performance, which makes Option D the best choice.
* IIA Standard 2110 - Governance: Internal auditors should assess decision-making processes, including managerial accounting techniques.
* IIA Standard 2120 - Risk Management: Cost control and budget variance analysis are key components of risk management.
* COSO Framework - Performance Monitoring: Emphasizes variance analysis, which aligns with predetermined standards in managerial accounting.
Key Reasons Why Option D is Correct:Why Other Options Are Incorrect:IIA References:Thus, the correct answer is D. Managerial accounting involves decision making based on predetermined standards.
