AWS Certified Cloud Practitioner (CLF-C02) is Amazon's entry-level cloud certification. It validates foundational knowledge of AWS services, pricing, security, and the shared responsibility model — without requiring any hands-on technical experience. It is the natural starting point for anyone moving into cloud or AWS roles.
Official prerequisite
None
Recommended experience
6 months of AWS exposure (any role) helpful but not required
No cloud experience required. Basic IT literacy helps.
Should you skip this exam?
If you already use AWS regularly or hold any other AWS certification, skip CLF-C02 and go straight to SAA-C03 or the role-specific Associate.
Courseiva study tip
Focus on the pricing and billing domain — it catches most people off guard. Know the difference between S3 storage classes and the shared responsibility model cold.
UK salary range
£30,000–£50,000 (entry cloud/IT roles)

You need a score of 700 out of 1000 to pass the CLF-C02 exam.
No. CLF-C02 is AWS's easiest certification. It tests conceptual knowledge only — no hands-on skills are required. Most candidates with 20–40 hours of study pass on their first attempt.
Most candidates need 20–40 hours of study. If you have some IT background, 2–3 weeks of evening study is typically enough.
Yes. CLF-C02 is valid for 3 years. After that you need to recertify by taking the latest version of the exam or a higher-level AWS certification.
CLF-C02 is a foundational credential. It helps with entry-level cloud roles, technical sales, IT administration, and demonstrates AWS literacy for any tech role. For engineering and architecture roles, the Associate-level certs carry far more weight.
Yes. The CLF-C02 is available via online proctoring through Pearson VUE OnVUE or PSI Bridge. You need a quiet room, a webcam, and a stable internet connection.

Sample questions
Select your answer before revealing the explanation. These questions are original exam-style — not copied from any exam or dump site.
Trap 1: Amazon SQS
SQS is a point-to-point queue — a message can be consumed by only one consumer. To deliver the same message to three services simultaneously, each service would need its own queue, requiring three separate publishes. SNS fan-out to multiple SQS queues is the standard pattern.
Trap 2: Amazon Kinesis Data Streams
Kinesis is designed for real-time data streaming and replay of large-volume streams. For simply delivering a notification to multiple services, SNS is the simpler and more appropriate service.
Trap 3: AWS EventBridge
EventBridge can route events to multiple targets and is a valid alternative, but SNS is the classic and most direct AWS service for fan-out pub/sub messaging to multiple simultaneous subscribers.
Amazon SQS
Why wrong: SQS is a point-to-point queue — a message can be consumed by only one consumer. To deliver the same message to three services simultaneously, each service would need its own queue, requiring three separate publishes. SNS fan-out to multiple SQS queues is the standard pattern.
Amazon SNS
SNS supports the fan-out pattern where a single message published to a topic is delivered to all subscribers simultaneously. The three services can each subscribe to the SNS topic and receive every product update message at the same time.
Amazon Kinesis Data Streams
Why wrong: Kinesis is designed for real-time data streaming and replay of large-volume streams. For simply delivering a notification to multiple services, SNS is the simpler and more appropriate service.
AWS EventBridge
Why wrong: EventBridge can route events to multiple targets and is a valid alternative, but SNS is the classic and most direct AWS service for fan-out pub/sub messaging to multiple simultaneous subscribers.
Trap 1: S3 One Zone-IA
S3 One Zone-IA stores data in a single Availability Zone, reducing availability. For frequently accessed thumbnails that need high availability, this is inappropriate.
Trap 2: S3 Glacier Flexible Retrieval
S3 Glacier Flexible Retrieval has retrieval times of minutes to hours. Thumbnails that are accessed multiple times per day need immediate access, making Glacier unsuitable.
Trap 3: S3 Standard-IA
S3 Standard-IA is for infrequently accessed data. Using it for data accessed multiple times per day incurs retrieval charges that would make it more expensive than S3 Standard.
S3 One Zone-IA
Why wrong: S3 One Zone-IA stores data in a single Availability Zone, reducing availability. For frequently accessed thumbnails that need high availability, this is inappropriate.
S3 Glacier Flexible Retrieval
Why wrong: S3 Glacier Flexible Retrieval has retrieval times of minutes to hours. Thumbnails that are accessed multiple times per day need immediate access, making Glacier unsuitable.
S3 Standard
S3 Standard is designed for frequently accessed data with high durability across three AZs and high availability. It provides immediate access with low latency — perfect for frequently read video thumbnails.
S3 Standard-IA
Why wrong: S3 Standard-IA is for infrequently accessed data. Using it for data accessed multiple times per day incurs retrieval charges that would make it more expensive than S3 Standard.
Trap 1: Amazon VPC
VPC provides network isolation but does not perform DNS resolution, health checking, or traffic failover routing.
Trap 2: Amazon CloudFront
CloudFront is a CDN that caches and delivers content. It does not perform DNS resolution or health-based failover routing for backend servers.
Trap 3: AWS Direct Connect
Direct Connect provides dedicated network connectivity between on-premises and AWS. It does not provide DNS, health checking, or traffic routing capabilities.
Amazon VPC
Why wrong: VPC provides network isolation but does not perform DNS resolution, health checking, or traffic failover routing.
Amazon CloudFront
Why wrong: CloudFront is a CDN that caches and delivers content. It does not perform DNS resolution or health-based failover routing for backend servers.
Amazon Route 53
Route 53 is AWS's DNS service. It translates domain names to IP addresses, performs health checks on endpoints, and supports failover routing policies that redirect traffic to a healthy resource when the primary fails.
AWS Direct Connect
Why wrong: Direct Connect provides dedicated network connectivity between on-premises and AWS. It does not provide DNS, health checking, or traffic routing capabilities.
Trap 1: Rapid elasticity
Rapid elasticity refers to the ability to scale resources up or down quickly. While related to cloud economics, it describes capacity flexibility rather than usage-based billing.
Trap 2: On-demand self-service
On-demand self-service is about the ability to provision resources without contacting the provider, not about how billing is calculated.
Trap 3: Resource pooling
Resource pooling is about the provider sharing infrastructure across customers, not about how customers are charged for what they use.
Measured service
Measured service is the cloud characteristic where resource usage is metered and customers are billed only for what they consume — compute hours, storage bytes, data transfer — with transparent reporting.
Rapid elasticity
Why wrong: Rapid elasticity refers to the ability to scale resources up or down quickly. While related to cloud economics, it describes capacity flexibility rather than usage-based billing.
On-demand self-service
Why wrong: On-demand self-service is about the ability to provision resources without contacting the provider, not about how billing is calculated.
Resource pooling
Why wrong: Resource pooling is about the provider sharing infrastructure across customers, not about how customers are charged for what they use.
Trap 1: Public cloud
Public cloud means all workloads run in the provider's infrastructure. This company still maintains on-premises infrastructure for its core banking system.
Trap 2: Private cloud
Private cloud means all resources are managed privately with no public cloud involvement. This company actively uses AWS, so it is not purely private cloud.
Trap 3: Multi-cloud
Multi-cloud means using multiple public cloud providers. This company uses one public cloud provider (AWS) combined with on-premises — that is hybrid, not multi-cloud.
Public cloud
Why wrong: Public cloud means all workloads run in the provider's infrastructure. This company still maintains on-premises infrastructure for its core banking system.
Hybrid cloud
Hybrid cloud integrates on-premises or private cloud infrastructure with public cloud resources. Running core systems on-premises while using AWS for analytics, connected via Direct Connect, is textbook hybrid cloud.
Private cloud
Why wrong: Private cloud means all resources are managed privately with no public cloud involvement. This company actively uses AWS, so it is not purely private cloud.
Multi-cloud
Why wrong: Multi-cloud means using multiple public cloud providers. This company uses one public cloud provider (AWS) combined with on-premises — that is hybrid, not multi-cloud.
Trap 1: Amazon EC2 with a self-managed MySQL installation
Running MySQL on EC2 gives full control but requires the customer to manage installation, patching, backups, and replication manually — the opposite of the stated requirement.
Trap 2: Amazon Redshift
Amazon Redshift is a managed data warehouse service designed for analytical queries against large datasets, not for operational OLTP relational database workloads.
Trap 3: Amazon ElastiCache
Amazon ElastiCache is an in-memory caching service (Redis or Memcached). It is not a relational database and does not support SQL schemas.
Amazon EC2 with a self-managed MySQL installation
Why wrong: Running MySQL on EC2 gives full control but requires the customer to manage installation, patching, backups, and replication manually — the opposite of the stated requirement.
Amazon RDS
Amazon RDS is a fully managed relational database service. AWS handles patching, automated backups, Multi-AZ failover, and monitoring while the customer focuses on schema design and queries.
