How many types of query suites are there?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Three types of query suites are typically used to cover different testing scopes: quick, isolated checks that verify individual queries' behavior; moderate-sized suites that check how multiple queries work together and share data; and comprehensive, end-to-end suites that simulate real-world usage and validate the entire workflow. This three-tier approach is right because it provides fast feedback, ensures interactions are correct, and confirms the system behaves as expected in realistic scenarios. Pairing fewer types would risk missing either integration issues or end-to-end correctness, while adding more categories often adds maintenance overhead without substantially improving coverage.
