1. A Certified Quality Inspector is primarily responsible for which core
function in a quality system?
A. Designing manufacturing processes
B. Performing financial audits of production costs
C. Verifying conformance of products to specifications
D. Managing corporate procurement contracts
Answer: C
A quality inspector’s primary role is to examine products and
processes to ensure they meet defined specifications, drawings, and
standards, rather than designing processes or handling financial or
procurement functions.
2. Which document is most critical for determining inspection
acceptance criteria?
A. Work order
B. Engineering drawing
C. Employee handbook
D. Shipping manifest
, Answer: B
Engineering drawings define tolerances, dimensions, and
specifications that inspectors use as the authoritative basis for
determining product conformity.
3. What is the main purpose of a calibration system in quality inspection?
A. To increase production speed
B. To ensure measurement accuracy of tools
C. To reduce workforce requirements
D. To eliminate inspection steps
Answer: B
Calibration ensures that measuring instruments produce accurate
and reliable readings, which is essential for valid inspection results.
4. Which of the following best describes a “nonconformance”?
A. A product that exceeds customer expectations
B. A deviation from a specified requirement
C. A product shipped ahead of schedule
D. A process that improves efficiency
Answer: B
A nonconformance occurs when a product, service, or process fails to
meet specified requirements or standards.
5. What is the primary purpose of sampling inspection?
A. Inspect every single unit produced
B. Reduce inspection time by testing all defects
C. Evaluate a subset of items to infer lot quality
D. Replace all quality documentation
Answer: C
Sampling inspection evaluates a representative portion of a lot to
determine whether the entire batch meets quality requirements.
, 6. Which tool is most appropriate for measuring internal diameters?
A. Outside micrometer
B. Vernier caliper inside jaws
C. Surface plate
D. Feeler gauge
Answer: B
The inside jaws of a vernier caliper are specifically designed to
measure internal dimensions such as hole diameters.
7. What is the purpose of Statistical Process Control (SPC)?
A. To eliminate inspection entirely
B. To monitor and control process variation
C. To increase production speed only
D. To replace engineering drawings
Answer: B
SPC uses statistical methods to monitor process variation and ensure
processes remain stable and capable.
8. Which term describes variation caused by random, inherent process
factors?
A. Assignable cause variation
B. Special cause variation
C. Common cause variation
D. Correctable defect variation
Answer: C
Common cause variation is natural and inherent in a process,
resulting from normal system fluctuations.
9. What is the purpose of a control chart?
A. To record employee attendance
B. To track inventory levels
C. To monitor process stability over time
