How to read a CLF-C02 question

  1. Find the operative keyword — words like *serverless*, *archive*, *real-time*, *NoSQL*, *DDoS*, *on-premises*, *audit* usually map directly to one service.
  2. Eliminate the obviously wrong two options first; most questions become a 50/50.
  3. Watch for superlatives — "MOST cost-effective", "LEAST operational overhead", "SIMPLEST". Two answers may work; pick the one that best satisfies the superlative. "Least operational overhead" almost always means the most managed/serverless option.
  4. Don't overthink — this is a foundational exam. The straightforward reading is usually right.
  5. Flag and move on if stuck; 90 minutes ÷ 65 questions ≈ 80 seconds each, so banking time on easy ones pays off.

The final week

  • Take Mock Exam 1 under real conditions. Review every miss and reread those lessons.
  • Drill your weakest domain in the practice bank.
  • Take Mock Exam 2. If you score 750+, book the real exam while the material is fresh.
  • The night before: skim the cheat sheet, then rest. Rested recall beats one more cram hour.
Exam tip

On exam day arrive 30 minutes early (or test your webcam/setup for online proctoring), bring two IDs for test centers, and remember: unanswered = wrong, so answer everything.

After you pass

Your certification lasts 3 years, and you get a 50% discount voucher for your next AWS exam. The natural next steps: Solutions Architect – Associate for a technical path, or AI Practitioner to add AI credentials — both on the Certivara roadmap.

A question asks for the option with the "LEAST operational overhead" to run code. Two technically valid answers are EC2 and Lambda. Which should you choose, and why?
