AWS Certified Cloud Practitioner AWS Certified Cloud Practitioner (CLFC01) Free Practice Test — 30 Questions
This practice bank of 30 questions exercises foundational AWS knowledge required for the CLFC01 exam. It tests understanding of core AWS services, the Shared Responsibility Model, disaster recovery strategies, data residency compliance, migration approaches, and cost optimization. Key decisions involve selecting appropriate AWS services for scalability, reliability, security, and operational efficiency. The scenarios emphasize practical application of concepts like Auto Scaling, Elastic Load Balancing, AWS Regions, IAM, encryption, and monitoring services. Mastery of these topics is critical for the exam.

This is an analysis of the practice bank, not a claim about the vendor's live exam blueprint. Use it to identify the knowledge, judgment, and recall patterns exercised here, then verify your coverage against the current official exam guide.
Core AWS Services and Architecture
This practice bank frequently tests knowledge of core AWS compute, storage, and database services and how they combine to build scalable, resilient architectures. Scenarios involve choosing between EC2, Lambda, Elastic Beanstalk, EKS, RDS, and S3 based on workload characteristics, performance needs, and operational overhead. Understanding when to use managed vs. unmanaged services is key.
- Recognize use cases for EC2, Lambda, Elastic Beanstalk, and EKS based on application requirements.
- Differentiate between Amazon RDS, Aurora, and self-managed databases on EC2.
- Understand how S3, CloudFront, and Global Accelerator support content delivery and data storage.
Security, Compliance, and Shared Responsibility
The Shared Responsibility Model is a recurring theme, particularly for data protection and encryption. Questions require identifying which security controls are customer-managed vs. AWS-managed. Services like IAM, KMS, CloudTrail, and GuardDuty are evaluated for meeting compliance requirements such as GDPR and data residency.
- Distinguish between customer and AWS responsibilities under the Shared Responsibility Model.
- Apply IAM policies, KMS encryption, and CloudTrail logging for audit and compliance.
- Select appropriate AWS Regions and Availability Zones to adhere to data residency laws.
Scalability, Performance, and Cost Optimization
Many scenarios involve handling unpredictable traffic spikes while controlling costs. AWS Auto Scaling, Elastic Load Balancing, and Savings Plans/Reserved Instances are central. The bank tests choosing between on-demand, reserved, or savings plans based on workload predictability, and between vertical and horizontal scaling strategies.
- Implement Auto Scaling and ELB to automatically adjust compute capacity.
- Evaluate cost savings from Reserved Instances and Savings Plans for stable workloads.
- Compare scaling approaches: vertical vs. horizontal, and when to use each.
Migration and Disaster Recovery
Migration strategies (lift-and-shift, re-architecting, blue/green deployment) and disaster recovery (pilot light, warm standby) are covered. Questions assess how to minimize downtime, enable rollback, and meet recovery objectives (RTO/RPO) when moving to AWS or recovering from failures.
- Choose appropriate migration strategy based on business continuity requirements.
- Design disaster recovery with multi-region deployments and services like AWS DRS.
- Evaluate trade-offs between pilot light, warm standby, and multi-site active-active architectures.

A global e-commerce platform hosted on AWS experiences significant, unpredictable surges in user traffic during promotional events. These surges often overwhelm their current infrastructure, leading to slow response times and intermittent service unavailability, directly impacting customer experience and sales. The platform\'s IT team has implemented basic security measures and is managing their EC2 instances manually. Which AWS capability should they prioritize to ensure continuous availability and optimal performance during these high-demand periods, aligning with their responsibilities under the AWS Shared Responsibility Model?
Study workflow
Turn one CLFC01 attempt into a study plan
- 1
Assess Workload Characteristics
Determine if the workload is predictable or variable, stateful or stateless, and its performance and compliance requirements. This guides service selection (e.g., EC2 for legacy, Lambda for auto-scaling) and determines whether to use Auto Scaling, Savings Plans, or Reserved Instances.
- 2
Apply the Shared Responsibility Model
Identify which security controls are customer-owned. For example, IAM policies, encryption of data at rest and in transit, and VPC configurations are your responsibility. AWS handles physical security, hypervisor, and network infrastructure.
- 3
Choose Regional Deployment
For data residency, deploy resources in the appropriate AWS Region. Use multiple Availability Zones for high availability. Understand that data stored in a Region stays within that Region unless you explicitly transfer it.
- 4
Implement Scalability Patterns
Use Auto Scaling groups with Elastic Load Balancers to handle traffic spikes. For stateful components, consider distributed caching (ElastiCache) or database read replicas. Monitor with CloudWatch and adjust scaling policies based on metrics.
- 5
Plan for Disaster Recovery
Define RTO and RPO. For regional failures, implement pilot light or warm standby in another Region via AWS DRS or manual snapshots. Regularly test failover procedures to ensure rapid recovery.
FAQ
Questions about this CLFC01 practice page
Clear boundaries on what the bank covers, how to use it, and where official vendor information still matters.
What is the difference between AWS CloudTrail and CloudWatch?+
CloudTrail records API activity for audit and compliance, while CloudWatch collects performance metrics, logs, and sets alarms. In the practice bank, CloudTrail is used for tracking resource changes, and CloudWatch for monitoring application health and scaling triggers.
How does the Shared Responsibility Model apply to data encryption?+
AWS manages encryption of the underlying infrastructure (e.g., EBS volume encryption at the hypervisor). The customer is responsible for encrypting data via services like KMS, enabling encryption in-transit (TLS), and configuring application-level encryption.
When should I use Amazon RDS versus self-managed databases on EC2?+
Use RDS for managed backups, patching, and scaling if your database is compatible. Choose EC2 with self-managed DB if you need custom extensions or full control over configuration, as in the practice bank scenario with a proprietary database.
What are AWS Savings Plans and how do they differ from Reserved Instances?+
Savings Plans offer flexible, hourly commitment across compute services (EC2, Lambda, Fargate) giving discounts similar to Reserved Instances but with more flexibility. Reserved Instances require a specific instance family and region. Both are suitable for predictable workloads as seen in the practice bank.
Why is blue/green deployment recommended for critical migrations?+
Blue/green deployment runs two environments (blue = existing, green = new) and switches traffic gradually. This allows immediate rollback if issues arise, minimizing downtime. The practice bank highlights this for applications where continuous availability is mandatory.
