Differentiate software validation from software verification in the CBM T6 context.

• A. Verification checks software meets requirements; validation confirms it fulfills its intended use; CBM T6 contexts require both for critical software.
• B. Validation and Verification are the same.
• C. CBM T6 contexts require only verification.
• D. CBM T6 contexts require neither verification nor validation.

Answer: (C)

Verification focuses on confirming the product is built right—it conforms to the design and requirements. Validation checks whether the product will do the right job in its real use and environment. In CBM T6 contexts, the prescribed practice is verification only, meaning you verify conformance to specifications and interfaces during development, while validating the intended use is not required within this context. This keeps the emphasis on correctness and conformance, with validation either addressed elsewhere or outside the scope of this CBM T6 assessment. The other options would imply that validation is also required, that verification and validation are the same, or that neither is needed, none of which aligns with the CBM T6 approach described.
