Q1. A company notices inconsistent customer records across multiple systems.
Which approach best ensures a single, reliable source of truth?
A. Increasing data entry speed
B. Implementing a master data management system
C. Deleting duplicate records manually
D. Limiting access to databases
Correct Answer: B. Implementing a master data management system
Explanation: Master Data Management (MDM) centralizes and
standardizes data across systems, ensuring consistency. Option A does not
address consistency, C is inefficient and error-prone, and D limits access but
does not resolve inconsistencies.
Q2. A business analyst needs to ensure data accuracy before reporting. What is
the most effective first step?
A. Data visualization
,B. Data validation and cleansing
C. Data storage optimization
D. Data encryption
Correct Answer: B. Data validation and cleansing
Explanation: Data must be accurate before analysis. Validation ensures
correctness, and cleansing removes errors. Visualization (A) comes later,
storage (C) is unrelated, and encryption (D) addresses security, not accuracy.
Q3. A database system enforces relationships between tables using foreign keys.
What is the primary purpose?
A. Improve query speed
B. Ensure referential integrity
C. Increase storage capacity
D. Encrypt sensitive data
Correct Answer: B. Ensure referential integrity
Explanation: Foreign keys maintain consistent relationships between tables.
A is performance-related, C is unrelated, and D is security-focused.
Q4. A manager wants dashboards updated in real time. Which system capability
is required?
A. Batch processing
B. Real-time data streaming
C. Manual data entry
D. Periodic backups
, Correct Answer: B. Real-time data streaming

processing (A) is delayed, manual entry (C) is inefficient, and backups (D) do
not affect real-time updates.
Q5. What is the main advantage of using a data warehouse over operational
databases?
A. Faster transaction processing
B. Optimized for analytical queries
C. Reduced data redundancy
D. Real-time updates
Correct Answer: B. Optimized for analytical queries
Explanation: Data warehouses are designed for analysis, not transactions. A
applies to operational systems, C is not guaranteed, and D is typically not a
warehouse feature.
Q6. A company uses role-based access control (RBAC). What is the primary
benefit?
A. Faster data retrieval
B. Simplified user permission management
C. Increased storage efficiency
D. Improved data visualization
