Instructions

Your primary challenge in this 70-question exam is accurate, applied thinking under timed conditions.

Pacing: 140 minutes for 70 questions allows approximately 2 minutes per question. Maintain your pace to ensure you complete the exam.

Question types: Questions are scenario-based and definition-based. Scenario questions require you to select the best action or identify the most likely cause given a realistic operational situation. Read each scenario carefully before selecting your answer.

Strategy: Eliminate answers you know are incorrect first. In ICS security, the correct answer often depends on whether the question is asking about OT-specific constraints (no active scanning, safety before containment, allow-listing over deny-listing) rather than standard IT security practice.

Break policy: You may take a single, self-managed break during the exam; however, the clock will not stop. Plan accordingly.

Goal: Achieve a 70% passing score. Focus on understanding ICS/OT security principles and how they differ from traditional IT security -- the exam tests this distinction throughout.

Review: Use any remaining time to revisit marked questions before submitting your final score.
