,Q1. In designing a relational database for an accounting information system, which normalization
step eliminates partial dependencies by ensuring that every non-key attribute is fully functionally
dependent on the entire primary key?
A. First Normal Form (1NF)
B. Second Normal Form (2NF)
C. Third Normal Form (3NF)
D. Boyce-Codd Normal Form (BCNF)
Correct Answer: B. Second Normal Form (2NF)
Rationale: Second Normal Form (2NF) requires that all non-key attributes be fully functionally dependent
on the entire primary key, eliminating partial dependencies. 1NF only requires atomic values; 3NF
eliminates transitive dependencies; BCNF is a stricter version of 3NF.
Why Wrong:
A - 1NF only requires atomic columns and a unique identifier, not addressing partial dependencies.
C - 3NF addresses transitive dependencies, not partial dependencies.
D - BCNF is a stronger form than 3NF and does not specifically target partial dependencies.

Q2. A company uses a cloud-based ERP system with role-based access control. Which combination
of segregation of duties conflicts would most likely arise if a single user is granted both the 'create
purchase order' and 'receive goods' roles?
A. Fraudulent payment processing and inventory theft
B. Duplicate vendor creation and unauthorized write-offs
C. Overstatement of accounts payable and understatement of inventory
D. Unauthorized credit memos and revenue overstatement
Correct Answer: A. Fraudulent payment processing and inventory theft
Rationale: Combining 'create purchase order' and 'receive goods' allows a user to create a fictitious
purchase and then record receipt, enabling fraudulent payment to a fake vendor and potential inventory
theft. Other conflicts involve different functions.
Why Wrong:
B - Vendor creation and write-offs are not directly related to purchase order and goods receipt.
C - Overstatement of AP and understatement of inventory would not directly result from this
conflict.
D - Credit memos and revenue overstatement relate to sales and billing cycles, not procurement.

, Q3. During an audit of a company's revenue cycle, an auditor uses Benford's Law to test the
distribution of invoice amounts. Which of the following findings would most strongly indicate
potential manipulation?
A. The first digit distribution closely matches Benford's expected frequencies
B. The last digit distribution shows an unusually high frequency of the digit 9
C. The first digit '1' appears 29% of the time and '9' appears 5% of the time
D. The second digit distribution shows a uniform distribution across digits 0-9
Correct Answer: B. The last digit distribution shows an unusually high frequency of the digit 9
Rationale: Benford's Law primarily applies to first digits; last digit analysis is not standard. However, a
high frequency of the digit 9 in the last position may suggest rounding up to avoid detection. Option C
matches expected Benford frequencies; option D shows uniformity which is not inherently suspicious.
Why Wrong:
A - Close match to Benford's Law indicates data integrity, not manipulation.
C - These percentages are within expected Benford frequencies for first digits.
D - Second digit distribution is not typically tested; uniformity is not a red flag.
Reference: Nigrini, M. J. (2020). Forensic Analytics, 2nd Ed., Ch. 3
Q4. Which of the following is the most critical control for preventing unauthorized access to
sensitive financial data in a public cloud environment?
A. Encryption of data at rest and in transit
B. Regular vulnerability scanning of the cloud infrastructure
C. Multi-factor authentication for all user accounts
D. Implementation of a security information and event management (SIEM) system
Correct Answer: C. Multi-factor authentication for all user accounts
Rationale: Multi-factor authentication (MFA) is the most effective control against credential theft and
unauthorized access. While encryption, vulnerability scanning, and SIEM are important, they do not
directly prevent unauthorized access if credentials are compromised.
Why Wrong:
A - Encryption protects data if accessed, but does not prevent unauthorized access itself.
B - Vulnerability scanning identifies weaknesses but does not prevent access in real time.
D - SIEM provides monitoring and alerting, but does not block unauthorized access.
