CISA-KR 문제 31
The programmer having access to the production programs is the most likely control weakness that would have contributed to the unauthorized changes to the payroll system report. This is because the programmer could modify the production code without proper authorization, documentation, or testing, and bypass the change management process. This could result in errors, fraud, or data integrity issues in the payroll system.
The programmer should only have access to the development or test environment, and the production programs should be under the control of a librarian or a change manager.

The best method to determine if IT resource spending is aligned with planned project spending is earned value analysis (EVA). EVA is a technique that compares the actual cost, schedule, and scope of a project with the planned or budgeted values. EVA can help to measure the project progress and performance, and identify any variances or deviations from the baseline plan1.
EVA uses three basic values to calculate the project status: planned value (PV), earned value (EV), and actual cost (AC). PV is the amount of work that was expected to be completed by a certain date, according to the project plan. EV is the amount of work that was actually completed by that date, measured in terms of the budgeted cost. AC is the amount of money that was actually spent to complete the work by that date1.
By comparing these values, EVA can determine if the project is on track, ahead, or behind schedule and budget. EVA can also calculate various indicators, such as cost variance (CV), schedule variance (SV), cost performance index (CPI), and schedule performance index (SPI), to quantify the magnitude and direction of the variances. EVA can also forecast the future performance and completion of the project, based on the current trends and assumptions1.
The other options are not as effective as EVA in determining if IT resource spending is aligned with planned project spending. Option B, return on investment (ROI) analysis, is a technique that evaluates the profitability or efficiency of an investment, by comparing the benefits or revenues with the costs. ROI analysis can help to justify or prioritize a project, but it does not measure the actual progress or performance of the project against the plan2. Option C, Gantt chart, is a tool that displays the tasks, durations, dependencies, and milestones of a project in a graphical format. Gantt chart can help to plan and monitor a project schedule, but it does not show the actual cost or scope of the project3. Option D, critical path analysis, is a technique that identifies the longest sequence of tasks or activities that must be completed on time for the project to finish on schedule. Critical path analysis can help to optimize and control a project schedule, but it does not account for the actual cost or scope of the project4.

Data analytics can be used to compare data from different sources and identify any discrepancies or anomalies. In this case, comparing a population of loans input in the origination system to loans booked on the servicing system can help detect any errors or frauds in the loan origination process. The other options are not examples of data analytics, but rather controls for data integrity, reconciliation, and error handling.

CISA-KR 문제 34
A balanced scorecard is a strategic planning framework that companies use to assign priority to their products, projects, and services; communicate about their targets or goals; and plan their routine activities1. The scorecard enables companies to monitor and measure the success of their strategies to determine how well they have performed. A balanced scorecard for IT management can help assess IT functions and processes by defining four perspectives: financial, customer, internal business process, and learning and growth2. These perspectives can help IT management align their IT objectives with the organization's vision and mission, identify and prioritize the key performance indicators (KPIs) for IT, and evaluate the effectiveness and efficiency of IT operations and services3.

CISA-KR 문제 35
A top-down approach in the development of IT policies means that the policies are derived from the strategic objectives and goals of the organization, and are aligned with the business needs and expectations. This should result in greater consistency across the organization, as the policies will be coherent, integrated and applicable to all levels and functions of the organization. A bottom-up approach, on the other hand, means that the policies are developed by individual units or departments based on their operational needs and preferences, which may lead to inconsistency, duplication or conflict among different policies.
