AWS Certified Cloud Practitioner CLF-C02 2026 Practice Exam – 190
Questions with Answers & Detailed Rationales, Cloud Concepts,
AWS Services, Security, Compliance, Pricing, Billing & Support
Domain 1: Cloud Concepts (Questions 1–46)
Question 1
A startup is evaluating whether to migrate its on-premises web application to AWS. The
company wants to avoid large upfront capital expenditures and only pay for the compute
resources it actually consumes.
Which cloud computing benefit directly addresses this requirement?
A. High availability
B. Elasticity
C. Trade fixed expense for variable expense
D. Global reach
Correct Answer: C
Explanation: AWS converts capital expenses (servers, data centers) into variable operational
expenses, allowing payment only for consumed resources. This is a core cloud economic
benefit.
Question 2
A media company needs to store video files that are accessed frequently for the first 30
days, then rarely accessed thereafter. The company wants to minimize storage costs without
manual intervention.
Which AWS design principle is being applied?
,A. Loose coupling
B. Design for failure
C. Automate lifecycle management
D. Implement elasticity
Correct Answer: C
Explanation: S3 Lifecycle policies automatically transition objects between storage classes,
optimizing cost based on access patterns without manual effort.
Question 3
An organization is concerned about a single point of failure in its application architecture.
The application currently runs on a single Amazon EC2 instance in one Availability Zone.
Which design principle should the organization adopt?
A. Implement elasticity
B. Remove single points of failure
C. Use managed services
D. Optimize for cost
Correct Answer: B
Explanation: Distributing resources across multiple Availability Zones eliminates single points
of failure, improving reliability and availability per the Well-Architected Framework.
Question 4
,A financial services firm must ensure its cloud architecture can recover from infrastructure
disruptions and dynamically acquire resources to meet demand.
Which AWS Well-Architected Framework pillar does this represent?
A. Security
B. Reliability
C. Performance efficiency
D. Operational excellence
Correct Answer: B
Explanation: The Reliability pillar focuses on a system's ability to recover from disruptions
and dynamically scale to meet demand. It includes designing for failure and self-healing.
Question 5
A company wants to reduce its environmental impact while running workloads in the AWS
Cloud. The company is evaluating its architecture against the Well-Architected Framework.
Which pillar addresses environmental sustainability?
A. Cost optimization
B. Operational excellence
C. Sustainability
D. Performance efficiency
Correct Answer: C
, Explanation: The Sustainability pillar, added to the Well-Architected Framework, focuses on
minimizing the environmental impacts of running cloud workloads.
Question 6
A global retail company wants to deploy its application in multiple AWS Regions to reduce
latency for customers worldwide.
Which benefit of the AWS global infrastructure does this represent?
A. Fault isolation
B. Global reach
C. Data sovereignty
D. Cost reduction
Correct Answer: B
Explanation: Deploying across multiple Regions provides global reach, allowing applications
to serve users with lower latency by placing resources closer to them.
Question 7
A company is migrating from on-premises infrastructure to AWS. The IT director wants to
understand how the AWS Cloud Adoption Framework (CAF) can help structure the
migration.
Which AWS CAF perspective focuses on building an enterprise-grade, scalable cloud
platform?
A. Business
B. People
C. Platform
