This FC0-U61 practice question tests your understanding of database fundamentals. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are advantages of using a relational database management system (RDBMS) over a file-based system?
Enforcement of data integrity
Constraints enforce accuracy and consistency.
Faster data access for all queries
Why wrong: Performance varies; indexed queries are fast, but not all.
Reduced data redundancy
Normalization reduces duplication.
No need for a database administrator
Why wrong: Most RDBMS environments require a DBA.
Simpler setup and maintenance
Why wrong: RDBMS is more complex than file-based.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enforcement of data integrity
A relational database management system (RDBMS) enforces data integrity through constraints such as primary keys, foreign keys, unique constraints, and check constraints. These rules ensure that data entered into the database adheres to defined business rules and referential integrity, preventing orphaned records and invalid data entries. In contrast, a file-based system relies on application code to enforce such rules, which is error-prone and inconsistent.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often assume 'faster data access' is always true for RDBMS due to indexing, but they overlook the overhead of SQL processing and the fact that file-based systems can be faster for simple, non-relational lookups.
Detailed technical explanation
Under the hood, an RDBMS uses a query optimizer to parse SQL statements and generate execution plans, leveraging indexes, B-trees, and caching to balance performance with data integrity. A real-world scenario where this matters is in an e-commerce platform: enforcing referential integrity ensures that an order cannot reference a non-existent customer, preventing data corruption that would be possible in a file-based system. Additionally, normalization in an RDBMS reduces data redundancy by decomposing tables into related entities, which minimizes update anomalies and storage waste.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
