AWS Cloud Practitioner Study Plan: Pass CLF-C02 Faster
AWS Cloud Practitioner is broad, vocabulary-heavy, and easier to over-study than under-study. You do not need to configure every AWS service. You need to recognize what each service is for, when it is priced a certain way, and how AWS frames security responsibility.
Know the four exam domains
CLF-C02 covers cloud concepts, security and compliance, cloud technology and services, and billing/pricing/support. The services domain is the largest, but security and pricing are where many candidates lose easy points.
Services to memorize first
Focus on high-frequency services before edge cases.
- Compute — EC2, Lambda, Elastic Beanstalk, ECS, EKS.
- Storage — S3, EBS, EFS, Glacier, Storage Gateway.
- Databases — RDS, DynamoDB, Redshift, Aurora.
- Security — IAM, KMS, Shield, WAF, GuardDuty, Security Hub.
Two-week schedule
Week one should be concept learning and service recognition. Week two should be practice tests, reviewing wrong answers, and memorizing billing/support details. If you score above 80% on two clean practice exams, schedule the real exam.
Common CLF-C02 traps
Candidates often confuse reserved instances with savings plans, mix up Trusted Advisor with AWS Config, and forget that IAM is global while most services are regional. Build a one-page mistake list and review it daily.
