ISA/IEC 62443 Cybersecurity Fundamentals Specialist — Question 44

Which of the following ISA-99 (IEC 62443) Reference Model levels is named correctly?

Answer options

• A. Level 1: Supervisory Control
• B. Level 2: Quality Control
• C. Level 3: Operations Management
• D. Level 4: Process

Correct answer: C

Explanation

The correct answer is C, as Level 3 is indeed referred to as Operations Management in the ISA-99 model. Options A, B, and D do not correctly represent the names of their respective levels, as they either misidentify or misclassify the levels according to the ISA-99 framework.
