What is the AWS Cloud Practitioner certification?
AWS Certified Cloud Practitioner (CLF-C02) is the entry-level AWS certification. It validates a broad, foundational understanding of the AWS Cloud — what the services do, how they fit together, and how security, pricing and support work — rather than deep hands-on engineering of any single service.
The exam spans four domains: cloud concepts, security and compliance, cloud technology and services, and billing, pricing and support. The recurring themes are the shared responsibility model, the roles of the core services (EC2, S3, RDS, Lambda, VPC), and how AWS charges for what you use.
This track breaks those domains into bite-sized, practical questions and uses spaced repetition so the service names and concepts move from "I read that once" to long-term recall — exactly what a broad, terminology-heavy exam like CLF-C02 rewards.
Not sure this is the right exam to sit? Which AWS certification should you choose? compares Cloud Practitioner against the three Associate exams — including why people who already build on AWS usually skip straight past it.

18 cardsSample questions
A taste of the real flashcards. Pick an answer, then reveal the explanation.
You need 200 servers for one afternoon. What makes the cloud fit?
- AResources come on demand and are billed only while they exist
- BHardware costs less per server than buying the same machines
- CCapacity is reserved in advance for the afternoon you name
- DServers are shared, so each one costs a fraction of the price
AWS secures the cloud itself. Which item does that cover?
- AThe physical data centres and the hypervisor under the instances
- BThe IAM users, roles and policies that exist in your account
- CThe guest operating system and the packages on your instances
- DThe security group rules that decide which ports are reachable
An EC2 instance is stopped. What are you still billed for?
- AIts attached EBS volumes, which keep existing while it is stopped
- BNothing at all, because billing ends the moment the instance stops
- CThe instance hours, charged at a reduced stopped-state rate per hour
- DIts instance store disks, which are preserved until you terminate it
Where do you put 40 TB of images that browsers fetch directly?
- AAmazon S3, where each image is an object served over HTTPS
- BAmazon EBS, with a volume per web server that grows as needed
- CAmazon EFS, with one shared mount that every web server reads
- DAn instance store, using the local disks of the serving instances

Why AWS fundamentals are worth your time
The default cloud
AWS is the largest cloud provider; knowing its building blocks is a baseline skill across most modern engineering roles.
A shared vocabulary
EC2, S3, IAM, VPC — fluency in the core services lets you follow architecture discussions instead of nodding along.
Spend and security sense
Understanding the shared responsibility model and the pricing models helps you avoid surprise bills and misconfigurations.
Certification-ready
The fundamentals here map directly to the four CLF-C02 exam domains.
Common questions
Do I need any AWS experience first? +
No. Cloud Practitioner is the entry point — this track starts from what the cloud is and builds up the core services, so beginners and people refreshing the basics both benefit.
How long does it take? +
About 10 minutes a day. Spaced repetition means short, frequent sessions beat cramming — most learners get comfortable with the fundamentals within a couple of weeks.
Is it free? +
Yes, completely free. No registration or credit card is required, and all your progress is stored locally in your browser.
Will this prepare me for the CLF-C02 exam? +
It covers the conceptual core the AWS Certified Cloud Practitioner (CLF-C02) exam tests across all four domains. It is a companion, not a full course — pair it with the official exam guide and some hands-on time in the AWS console.
