,Q1. In an ERP system, which of the following best describes the primary advantage of using a single
integrated database for accounting and operational data?
A. Reduced need for data validation
B. Elimination of data redundancy
C. Real-time data consistency across modules
D. Simplified user access controls
Correct Answer: C. Real-time data consistency across modules
Rationale: A single integrated database ensures that data entered in one module (e.g., sales) is
immediately available in others (e.g., inventory, accounting), providing real-time consistency. While it
reduces redundancy (B), it does not eliminate it entirely, and it does not reduce the need for data
validation (A) or simplify access controls (D).
Why Wrong:
A - Data validation is still required to ensure accuracy and completeness.
B - Redundancy is reduced but not fully eliminated; duplicate data can still exist.
D - Access controls become more complex due to integrated data across modules.

Q2. A company uses a continuous auditing approach that relies on embedded audit modules (EAMs)
to monitor transactions. Which of the following is a key limitation of this approach?
A. EAMs cannot detect unauthorized access to the system.
B. EAMs require significant manual intervention to set parameters.
C. EAMs are ineffective for detecting errors in non-financial data.
D. EAMs may slow down transaction processing due to real-time monitoring.
Correct Answer: D. EAMs may slow down transaction processing due to real-time monitoring.
Rationale: Embedded audit modules operate in real-time, which can degrade system performance and
slow transaction processing, especially in high-volume environments. EAMs can detect unauthorized
access (A) if programmed to do so. They are automated and require minimal manual intervention after
setup (B). They can be configured to monitor any data type, not just financial (C).
Why Wrong:
A - EAMs can be designed to detect unauthorized access patterns.
B - Once configured, EAMs operate automatically with little manual effort.
C - EAMs can monitor any data, including non-financial, based on rules.

, Q3. Which of the following data analytics techniques is most appropriate for identifying anomalies
in journal entries that may indicate fraudulent financial reporting?
A. Regression analysis to predict future account balances
B. Benford's Law analysis to test the distribution of leading digits
C. Cluster analysis to group similar transactions
D. Time-series analysis to detect seasonal patterns
Correct Answer: B. Benford's Law analysis to test the distribution of leading digits
Rationale: Benford's Law is commonly used in fraud detection to identify unnatural patterns in numerical
data, such as fabricated journal entries, because genuine data sets follow a predictable distribution of
leading digits. Regression (A) predicts trends, not anomalies. Cluster analysis (C) groups similar items
but does not flag individual anomalies. Time-series (D) identifies patterns over time, not specific outliers.
Why Wrong:
A - Regression predicts future values, not anomalies in existing data.
C - Cluster analysis groups data but does not specifically identify outliers.
D - Time-series analysis focuses on patterns over time, not individual anomalies.

Q4. An organization is implementing a new cloud-based accounting system. Which of the following
controls is most critical for ensuring data integrity during the transition?
A. Implementing role-based access controls in the new system
B. Performing parallel runs of old and new systems
C. Encrypting data at rest and in transit
D. Conducting user acceptance testing
Correct Answer: B. Performing parallel runs of old and new systems
Rationale: Parallel runs allow comparison of outputs from both systems to verify that data is accurately
migrated and processed, directly ensuring data integrity. Role-based access (A) and encryption (C) are
important for security, not specifically for transition integrity. User acceptance testing (D) checks
functionality but may not catch data accuracy issues.
Why Wrong:
A - Access controls are for security, not for verifying data accuracy during migration.
C - Encryption protects data confidentiality, not integrity during transition.
D - UAT focuses on system functionality, not data accuracy in migration.
