The AWS Certified Cloud Practitioner (CLF-C02) is the entry point to AWS certification. It proves you understand what the cloud is, what the main AWS services do, how AWS is secured and how it is priced. It does not expect you to build complex architectures, which makes it ideal for career changers, managers, sales and finance people, students, and engineers starting their AWS journey.
The exam in brief
- Format: multiple choice and multiple response questions, 90 minutes. Some questions are unscored pilot items.
- Passing score: 700 on a scale of 100–1000.
- Delivery: at a test center or online proctored.
Check the official exam guide on the AWS Certification site before you book: it lists the exact domains, weights and in-scope services, and AWS updates it over time.
The four domains
| Domain | What it covers |
|---|---|
| Cloud Concepts | Benefits of the cloud, the Well-Architected Framework, migration strategies, cloud economics |
| Security and Compliance | Shared responsibility model, IAM, security services, compliance resources |
| Cloud Technology and Services | Deployment methods, global infrastructure, compute, databases, networking, storage, AI/ML and analytics services |
| Billing, Pricing and Support | Pricing models, cost tools, support plans, AWS Marketplace |
Technology and services is the largest domain, followed by security.
Concepts you must be sure about
- Shared responsibility model: AWS secures the cloud (hardware, facilities, global network, managed service infrastructure); you secure what you put in it (data, IAM, OS patching on EC2, security group rules, encryption choices). Expect several questions that test where the line falls for EC2 vs RDS vs Lambda.
- Global infrastructure: Regions, Availability Zones, edge locations, Local Zones. Know why you spread across AZs and why you choose a Region (latency, compliance, service availability, price).
- The six advantages of cloud computing and the six pillars of the Well-Architected Framework (operational excellence, security, reliability, performance efficiency, cost optimization, sustainability).
- Pricing models: On-Demand, Savings Plans, Reserved Instances, Spot, Dedicated Hosts; plus free tier, data transfer basics and how storage is priced.
- Cost tools: AWS Pricing Calculator (estimate before you build), Cost Explorer (analyze spend), AWS Budgets (alerts), Cost and Usage Report, cost allocation tags.
- Support plans: Basic, Developer, Business, Enterprise On-Ramp, Enterprise. Know which include a technical account manager and which give 24/7 access to engineers.
Services to know by purpose
| Category | Services |
|---|---|
| Compute | EC2, Lambda, ECS, EKS, Fargate, Elastic Beanstalk, Lightsail |
| Storage | S3 (and storage classes), EBS, EFS, FSx, S3 Glacier, AWS Backup, Storage Gateway |
| Databases | RDS, Aurora, DynamoDB, ElastiCache, Redshift, Neptune, DocumentDB |
| Networking | VPC, Route 53, CloudFront, Direct Connect, VPN, Global Accelerator, ELB |
| Security | IAM, IAM Identity Center, KMS, Shield, WAF, GuardDuty, Inspector, Macie, Security Hub, Artifact |
| Management | CloudWatch, CloudTrail, Config, Systems Manager, Trusted Advisor, Organizations, Control Tower |
You do not need to configure these; you need to recognize which service fits a described need. "Record API calls for auditing" is CloudTrail; "evaluate resource configurations against rules" is Config; "find exposed sensitive data in S3" is Macie.
A four-week study plan
- Week 1: Cloud concepts, global infrastructure, IAM basics. Create a free account or sandbox, set up MFA, create an IAM user and group.
- Week 2: Compute, storage and networking. Launch an EC2 instance, host a website on S3, build a VPC.
- Week 3: Databases, security services, monitoring. Create an RDS database and a DynamoDB table; explore CloudWatch and CloudTrail.
- Week 4: Pricing, support and review. Use the Pricing Calculator, read the support plan comparison, and take practice exams, studying every wrong answer.
Why hands-on practice helps even for a "non-technical" exam
Many questions describe a scenario and ask which service fits. If you have actually created an S3 bucket, seen a security group block traffic or watched a CloudWatch alarm fire, the right answer is obvious instead of memorized. Twenty minutes in a real console beats an hour of flashcards.
Cloud Arena's AWS Certified Cloud Practitioner path follows the exam's services with guided labs in real AWS accounts, and every task is checked automatically. Start with the free labs: Host Your First Website on Amazon S3, VPC with Public and Private Subnets and Getting Started with Amazon DynamoDB.
Exam-day tips
- Read the last line of the question first: it tells you what is being asked.
- Eliminate obviously wrong answers; two options are often clearly out.
- Watch for keywords: "most cost-effective", "least operational overhead", "highly available".
- Flag and move on; come back with fresh eyes. There is no penalty for guessing.
FAQ
Do I need technical experience?
No. AWS recommends some familiarity with the cloud, which you can build during your preparation.
Should I skip Cloud Practitioner and go straight to Solutions Architect Associate?
If you already work with AWS daily, you can. If you are new, CLF-C02 builds the vocabulary that makes the associate exams much easier.
How long is the certification valid?
Three years. You recertify by passing the current version or a higher-level exam.
