Explanations & Success Workbook
What's New in 2026 for CLF-C02
AWS refreshed the CLF-C02 exam guide in early 2026 with significant updates:
• Generative AI and ML — Amazon Bedrock, Amazon Q, and foundational
model concepts now have dedicated mention
• Security & Compliance expansion — More detailed coverage of IAM
policies, ABAC, cross-account access
• Sustainability — The AWS Well-Architected Framework's sustainability
pillar is now an explicit objective

Instance flexibility, AWS Cost Optimization Hub
DOMAIN 1: CLOUD CONCEPTS (24%)
Questions 1–24
Question 1
Which of the following is a key benefit of cloud computing that allows
organizations to trade capital expense (CapEx) for operational expense (OpEx)?
A) High availability
B) Pay-as-you-go pricing
C) Global reach
D) Fault tolerance
Answer: B) Pay-as-you-go pricing
,Rationale: Pay-as-you-go pricing allows organizations to trade capital expense
(CapEx) for operational expense (OpEx) — no upfront investment, only paying for
what is consumed. High availability (A) refers to systems remaining operational
without downtime. Global reach (C) refers to deploying applications in multiple
geographic locations. Fault tolerance (D) refers to systems surviving component
failures without degradation.
Question 2
Which of the following best describes the AWS Well-Architected Framework?
A) A set of security best practices for AWS deployments
B) A framework of six pillars that provides best practices for designing and
operating reliable, secure, efficient, and cost-effective systems in the cloud
C) A cost optimization tool for AWS resources
D) A monitoring service for AWS infrastructure
Answer: B) A framework of six pillars that provides best practices for
designing and operating reliable, secure, efficient, and cost-effective systems
in the cloud
Rationale: The AWS Well-Architected Framework consists of six pillars —
Operational Excellence, Security, Reliability, Performance Efficiency, Cost
Optimization, and Sustainability — that provide best practices for cloud
architecture. It is not just security (A), a cost tool (C), or a monitoring service (D).
Question 3
A company wants to deploy applications closer to users in multiple geographic
locations to reduce latency. Which cloud computing benefit enables this?
A) Increase speed and agility
B) Go global in minutes
C) Stop guessing capacity
D) Economy of scale
Answer: B) Go global in minutes
,Rationale: "Go global in minutes" means you can deploy applications in multiple
AWS Regions around the world with just a few clicks, bringing applications closer
to end users for lower latency. Speed and agility (A) refers to rapid resource
provisioning. Stop guessing capacity (C) refers to scaling based on demand.
Economy of scale (D) refers to lower costs from AWS's scale.
Question 4
Which of the following is NOT one of the six pillars of the AWS Well-Architected
Framework?
A) Operational Excellence
B) Security
C) Cost Optimization
D) Network Performance
Answer: D) Network Performance
Rationale: The six pillars of the AWS Well-Architected Framework are
Operational Excellence, Security, Reliability, Performance Efficiency, Cost
Optimization, and Sustainability. Network Performance is not a pillar — it falls
under Performance Efficiency.
Question 5
What is the primary purpose of the AWS Cloud Adoption Framework (CAF)?
A) To provide a structure for migrating workloads to the cloud with guidance
across business, people, governance, platform, security, and operations
perspectives
B) To define security best practices for AWS
C) To provide cost estimation tools
D) To monitor AWS resources
Answer: A) To provide a structure for migrating workloads to the cloud with
guidance across business, people, governance, platform, security, and
operations perspectives
, Rationale: The AWS CAF provides a structure to migrate workloads, organized
into six perspectives: Business, People, Governance (business perspectives);
Platform, Security, Operations (technical perspectives). It is not just security (B),
cost (C), or monitoring (D).
Question 6
Which cloud computing characteristic allows systems to automatically
scale resources based on demand?
A) High availability
B) Fault tolerance
C) Elasticity
D) Agility
Answer: C) Elasticity
Rationale: Elasticity is the ability to automatically scale resources up or down
based on workload demand. High availability (A) refers to systems remaining
operational. Fault tolerance (B) refers to surviving component failures. Agility (D)
refers to rapid provisioning of resources.
Question 7
Which of the following is an example of capital expenditure (CapEx) in the
context of cloud computing?
A) Monthly AWS service fees
B) Pay-as-you-go compute charges
C) Purchasing physical servers for an on-premises data center
D) AWS Support Plan costs
Answer: C) Purchasing physical servers for an on-premises data center
Rationale: Capital expenditure (CapEx) involves upfront investment in physical
assets like servers, storage, and networking equipment. Monthly AWS fees (A),
pay-as-you-go charges (B), and Support Plan costs (D) are operational expenses
(OpEx).
