What Is AWS Certified Cloud Practitioner CLF-C02?

AWS Certified Cloud Practitioner is a foundational AWS certification designed to validate overall knowledge of the AWS Cloud, its core services, terminology, security concepts, cloud economics and common AWS use cases.

The CLF-C02 certification is not limited to one technical job role. It is particularly useful for people beginning an AWS or cloud career, professionals who work with cloud teams, and business or technical professionals who want a strong understanding of AWS Cloud.

The current AWS exam guide identifies four major content domains: Cloud Concepts, Security and Compliance, Cloud Technology and Services, and Billing, Pricing, and Support.

CLF-C02 Is a Cloud Foundation Certification

You do not need to become an AWS architect, developer or administrator before taking Cloud Practitioner. The goal is to understand what AWS services do, when they are used, how cloud security works, how AWS pricing works and how the major AWS services fit together.

Underlying hardware
Global AWS infrastructure
Foundation of managed services

Customer Responsibilities

Identity and access configuration
Data protection
Application security
Network configuration where applicable
Operating system patching for services such as EC2
Security configuration

AWS Global Infrastructure Explained

Region: A geographic area containing multiple Availability Zones.
Availability Zone: An isolated location within an AWS Region.
Edge location: A location used by AWS services such as CloudFront to serve content closer to users.
Multi-AZ: Used to improve availability and resilience.
Multi-Region: Can support disaster recovery, business continuity, latency and data sovereignty requirements.
