CA Information Systems 2 — Questions and Answers
Question 1: Which control ensures that data entered into an accounting system falls within a predefined acceptable range?
- Completeness check
- Range check (Correct answer)
- Validity check
- Sequence check
Correct answer: Range check
A range check validates that entered data values fall between a specified minimum and maximum to prevent out-of-bounds entries.
Question 2: In a relational database, a foreign key is used to:
- Uniquely identify each record in a table
- Encrypt sensitive data fields
- Establish a link between two tables (Correct answer)
- Index frequently queried columns
Correct answer: Establish a link between two tables
A foreign key references the primary key of another table, enforcing referential integrity between related tables.
Question 3: Which disaster recovery strategy involves maintaining a fully operational duplicate site ready to take over immediately?
- Cold site
- Warm site
- Hot site (Correct answer)
- Mirror archive
Correct answer: Hot site
A hot site is a fully equipped and operational backup facility that can assume production workloads immediately after a failure.
Question 4: The primary purpose of an IT general control (ITGC) review is to:
- Test individual transaction accuracy
- Assess controls over the IT environment that support application controls (Correct answer)
- Verify software license compliance
- Evaluate network bandwidth utilization
Correct answer: Assess controls over the IT environment that support application controls
ITGCs encompass controls over change management, access, and operations that provide the foundation for application-level controls.
Question 5: A hash total used as a batch control is best described as:
- A sum of meaningful dollar amounts for reconciliation
- A meaningless arithmetic total of a non-dollar field used for error detection (Correct answer)
- An encrypted checksum of transmitted data
- A count of records processed in a batch
Correct answer: A meaningless arithmetic total of a non-dollar field used for error detection
A hash total is the sum of a field (such as account numbers) that has no inherent meaning but detects missing, added, or altered records.
Question 6: Which access control model assigns permissions based on an individual's role within the organization?
- Discretionary Access Control (DAC)
- Mandatory Access Control (MAC)
- Role-Based Access Control (RBAC) (Correct answer)
- Attribute-Based Access Control (ABAC)
Correct answer: Role-Based Access Control (RBAC)
RBAC grants access rights to users based on their assigned organizational roles, simplifying permission management.
Question 7: Which of the following best describes a 'system changeover' using the parallel operation method?
- The old system is shut down before the new one starts
- Both old and new systems run simultaneously until the new system is verified (Correct answer)
- Users are migrated in phases by department
- The new system replaces the old one over a single weekend
Correct answer: Both old and new systems run simultaneously until the new system is verified
Parallel operation runs both systems concurrently so outputs can be compared, reducing risk before full cutover.
