About the CLF-C02 exam
CLF-C02 checks whether a candidate understands the AWS Cloud at a foundational level: what it offers, how it is secured, what it costs and where to get help. Passing it earns the AWS Certified Cloud Practitioner certification. Candidates range from sales, finance and legal staff to project managers and early-career IT workers, and no technical background is required. AWS recommends six months of AWS Cloud exposure before the exam. The certification stays valid for three years.
Cloud Technology and Services is the largest domain, so the PlanetCert practice test gives most of its questions to services such as Amazon EC2, Amazon S3, Amazon VPC and AWS Lambda. The explanations say why one service fits and the nearest alternative does not, for example Amazon EFS against Amazon EBS. Flashcard mode suits the long list of service names. Brainy AI Assistant can explain which side of the shared responsibility model owns a task, or compare two pricing options for a steady workload.

How to prepare for CLF-C02
- 1
Click through the console once
Launch an EC2 instance, create an S3 bucket and open a VPC in the AWS Management Console, then delete them. Seeing each service once makes the names in the questions concrete.
- 2
Draw the shared responsibility line
List common tasks, such as patching a guest operating system or securing a data center, and mark each one as AWS's job or the customer's. Many Security and Compliance questions turn on this split.
- 3
Learn services in families
Group the services as the exam guide does: compute, storage, database, network, AI/ML and analytics, and the other in-scope categories. Learn one sentence per service that says when to choose it.
- 4
Compare the pricing options
Put On-Demand Instances, Reserved Instances, Savings Plans, Spot Instances and Dedicated Hosts side by side with the workload each one suits. Add AWS Budgets, AWS Cost Explorer and the Pricing Calculator to the same sheet.
