The primary objective of a disaster recovery plan is recovery of interrupted IT-related activities in a way that minimizes the impact of the disruption. Official ISACA definitions describe disaster recovery as activities and programs designed to return the enterprise to an acceptable condition and restore critical business functions through a DRP. ISACA's glossary defines a disaster recovery plan (DRP) as a set of human, physical, technical, and procedural resources to recover an interrupted activity within a defined time and cost.
Among the answer choices, A. Minimizing loss of information is the best match. ISACA guidance states that a DRP contains procedures for restoring systems and data, minimizing loss of information and downtime, and ensuring business continuity. This makes option A the strongest answer because it captures a direct purpose of the DRP itself.
Option B ("Assessing the risk of key applications") is an important planning activity, but it is not the primary objective of the DRP. Risk assessment is part of developing continuity capability, not the ultimate aim of the plan. ISACA continuity guidance treats assessing risks and impacts as a step in the DRP process, not the main end goal.
Option C ("Identifying key business processes") is also an important prerequisite, typically associated more with business impact analysis and business continuity planning. It helps define what must be protected and restored, but it is not itself the primary objective of the DRP. ISACA distinguishes business continuity activities from disaster recovery, with DR focusing more specifically on restoring IT systems, infrastructure, and data after disruption.
Option D ("Documenting all IT assets") may support recovery preparedness, but this is clearly not the primary objective of a DRP. Asset documentation is administrative and supportive; the goal of the plan is restoration and recovery with minimal disruption and data loss.
Therefore, A is the correct answer because official ISACA material directly states that the DRP is intended to restore systems and data while minimizing loss of information and downtime.

Reconciliation of total amounts by project is the best control to ensure that data is accurately entered into the job-costing system from spreadsheets. Reconciliation is a process of comparing two sets of data to identify any differences or discrepancies between them. By reconciling the total amounts by project from spreadsheets with those from the job-costing system, any errors or omissions in data entry can be detected and corrected.
Validity checks are controls that verify that data conforms to predefined formats or ranges. They can prevent entry of character data into numeric fields, but they cannot ensure that the numeric data is correct or complete.
Reasonableness checks are controls that verify that data is within expected or acceptable limits. They can detect outliers or anomalies in data, but they cannot ensure that the data matches the source. Display back of project detail after entry is a control that allows the user to review and confirm the data entered into the system. It can help reduce human errors, but it cannot guarantee that the data is accurate or consistent with the source.

Capability maturity models (CMMs) are frameworks that help organizations assess and improve their processes in various domains, such as software development, project management, service delivery, and cybersecurity1. CMMs define different levels of process maturity, from initial to optimized, and describe the characteristics and best practices of each level. By using CMMs, organizations can benchmark their current processes against a common standard, identify gaps and weaknesses, and implement improvement actions to achieve higher levels of process maturity2. CMMs can also help organizations align their processes with their strategic goals, measure their performance, and increase their efficiency, quality, and customer satisfaction3.
Therefore, the use of CMMs would best enhance a process improvement program, as they provide a systematic and structured approach to evaluate and improve processes based on proven principles and practices. Option C is the correct answer.
Option A is not correct because model-based design notations are graphical or textual languages that help designers specify, visualize, and document the structure and behavior of systems4. While they can be useful for designing and communicating complex systems, they do not directly address the process improvement aspect of a program.
Option B is not correct because balanced scorecard is a strategic management tool that helps organizations translate their vision and mission into measurable objectives and indicators. While it can be useful for monitoring and evaluating the performance of a program, it does not provide specific guidance on how to improve processes.
Option D is not correct because project management methodologies are sets of principles and practices that help organizations plan, execute, and control projects. While they can be useful for managing the scope, schedule, cost, quality, and risk of a program, they do not focus on the process improvement aspect of a program.
