How to read a CLF-C02 question
- Find the operative keyword — words like *serverless*, *archive*, *real-time*, *NoSQL*, *DDoS*, *on-premises*, *audit* usually map directly to one service.
- Eliminate the obviously wrong two options first; most questions become a 50/50.
- 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.
- Don't overthink — this is a foundational exam. The straightforward reading is usually right.
- Flag and move on if stuck; 90 minutes ÷ 65 questions ≈ 80 seconds each, so banking time on easy ones pays off.
Superlative → answer pattern
| When the question says… | Lean toward… |
|---|---|
| Least operational overhead / no servers to manage | Serverless & managed: Lambda, Fargate, DynamoDB, RDS, S3 |
| Most cost-effective for interruptible work | Spot Instances |
| Most cost-effective for steady 24/7 work | Reserved Instances / Savings Plans |
| Highly available | Multi-AZ, ELB + Auto Scaling |
| Global users, low latency | CloudFront, Route 53, multiple Regions |
| Compliance evidence about AWS itself | AWS Artifact |
| Who performed an action | CloudTrail |
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.
Knowledge check
Question 1 of 2A 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?
