Question

Options

Explanation

Verifying model completeness and consistency requires active testing mechanisms: the Test lab (B) lets you run scenarios through the model to expose missing paths or contradictory outcomes; the 'check' option in the Decision table (C) specifically validates that decision rules are complete (all inputs covered) and consistent (no conflicting rules); and the Simulation tool (D) executes the model dynamically to reveal logical gaps or behavioral inconsistencies that static inspection would miss. The Diagram comparison (A) is incorrect because it only highlights structural differences between two versions of a model - it does not validate correctness or completeness. The Syntax check (E) is incorrect because it only verifies that the model is structurally well-formed (correct notation usage), not that its logic is complete or free of contradictions.

Memory tip: Think of the three correct answers as "running the model" - Test lab, Check (in Decision tables), and Simulation all actively execute or evaluate logic, while the distractors (Diagram comparison and Syntax check) are purely passive structural inspections that can't catch missing or conflicting logic.
