AWS Cloud Practitioner in 30 Days

The AWS Certified Cloud Practitioner (CLF-C02) is achievable in 30 days with focused, daily study. At 1-2 hours per day, you can comfortably cover all four domains and pass your exam.

Why Start with Cloud Practitioner?

CLF-C02 is the entry point to the AWS certification track. It validates foundational cloud literacy and is recognised by thousands of employers as a signal of cloud competence. No prior cloud experience is required.

Exam Overview

• 65 questions (multiple choice and multiple response)
• 90 minutes
• Scaled score approximately 700/1000 to pass
• Valid for 3 years
• Cost: USD 100 (vouchers often available through AWS Training)

The Four Domains and What to Focus On

Domain 1: Cloud Concepts (24%)

The value proposition of cloud computing, AWS global infrastructure (Regions, AZs, Edge Locations), the 6 advantages of cloud (trade capital for operational expense, massive economies of scale, stop guessing capacity, increase speed and agility, stop spending on data centres, go global in minutes).

Domain 2: Security and Compliance (30%)

Tour is the highest-weighted domain. Focus on: Shared Responsibility Model (AWS manages security OF the cloud, you manage security IN the cloud), IAM (users, groups, roles, policies), MFA, encryption at rest and in transit, compliance programmes (HIPAA, SOC, PCI DSS).

Domain 3: Cloud Technology and Services (34%)

The largest domain. Core services to know well:

• Compute: EC2 (instance types and pricing), Lambda, ECS, EKS, Fargate, Elastic Beanstalk
• Storage: S3 (storage classes), EBS, EFS, Glacier, Storage Gateway
• Databases: RDS, Aurora, DynamoDB, Redshift, ElastiCache
• Networking: VPC, subnets, security groups, NACLs, Route 53, CloudFront
• Monitoring: CloudWatch, CloudTrail, AWS Config, Trusted Advisor

Domain 4: Billing, Pricing and Support (12%)

Pricing models (On-Demand, Reserved, Spot, Savings Plans), Cost Explorer, Budgets, pricing calculators, support plans (Basic, Developer, Business, Enterprise).

30-Day Daily Study Plan

• Days 1-5: Cloud concepts, AWS global infrastructure, 6 advantages
• Days 6-12: Security - Shared Responsibility Model, IAM deep dive, compliance
• Days 13-20: Core services - EC2, S3, RDS, Lambda, VPC, CloudFront, Route 53, CloudWatch
• Days 21-25: Billing, pricing models, support plans, Cost Explorer
• Days 26-30: Daily practice exams. Review every wrong answer. Identify weak areas and revisit.

The 30-day plan, day by day

Week 1 (Days 1–7): Core concepts. AWS Global Infrastructure (Regions, AZs, Edge Locations). Core services: EC2, S3, RDS, Lambda. IAM fundamentals. The Shared Responsibility Model. Pricing models (On-Demand, Reserved, Spot). Spend 45 minutes per day reading, then 15 minutes on Dragonfly practice questions for that day's topic.

Week 2 (Days 8–14): Service depth. CloudFront, Route 53, VPC fundamentals, Load Balancers, Auto Scaling. Security services: KMS, Shield, WAF, Inspector, GuardDuty. Storage services: EBS, EFS, Storage Gateway, Snow family. Continue daily practice questions focused on each day's topics.

Week 3 (Days 15–21): Breadth across all domains. Database services: DynamoDB, Aurora, ElastiCache, Redshift. Application services: SQS, SNS, EventBridge, Step Functions. Management tools: CloudWatch, CloudTrail, Config, Trusted Advisor. Billing: Cost Explorer, Budgets, Savings Plans.

Week 4 (Days 22–30): Practice tests and gap closure. Do a full 65-question practice test on Day 22. Review every wrong answer in detail. Spend Days 23–27 on your weakest domains. Day 28–29: two more full practice tests. Day 30: light review only, rest, sleep well.

What the exam actually tests

The CLF-C02 exam has 65 questions (50 scored, 15 unscored) and a 90-minute time limit. The four domains are: Cloud Concepts (24%), Security and Compliance (30%), Cloud Technology and Services (34%), and Billing, Pricing, and Support (12%). Security is the largest domain — many candidates underweight it. Know the Shared Responsibility Model in detail, understand which services are customer-managed versus AWS-managed, and know the security services (Shield, WAF, GuardDuty, Inspector, Macie) and what each one does.

Free study resources from AWS

AWS provides free official training specifically designed for Cloud Practitioner preparation through AWS Skill Builder (explore.skillbuilder.aws). The Cloud Practitioner Essentials course is available at no cost and covers all four exam domains in structured modules with knowledge checks. Supplementing paid courses with AWS Skill Builder is strongly recommended because official materials reflect the exact terminology and service descriptions that appear in the actual exam — third-party courses sometimes use different wording for the same concepts, which can cause confusion in the exam.

Practice exams are the single most effective preparation tool in the final two weeks before your sitting. AWS offers an official practice exam through AWS Skill Builder (paid), but free community practice exams are widely available and sufficient. Aim for a consistent score of 80% or above on practice exams before booking — the real exam pass mark is 700/1000 (approximately 70%), but practising to a higher standard gives you a buffer for exam-day pressure and unfamiliar question phrasing.
