Exam Title: AWS Certified Cloud Practitioner (CLF-C02) – 150 Advanced & Mixed Difficulty
Practice Questions with Detailed Rationales
Domain 1: Cloud Concepts (24%) – Questions 1–36
Question 1
A multinational e-commerce company is migrating its on-premises infrastructure to AWS. The
CFO is concerned about the financial implications of moving from a capital expenditure (CAPEX)
model to an operational expenditure (OPEX) model. Which of the following correctly describes a
key financial benefit of this transition?
A) AWS requires a long-term capital investment upfront for reserved capacity
B) The company can trade capital expense for variable expense and pay only for what they use
C) The company must purchase physical servers in advance to ensure capacity
D) AWS charges a fixed monthly fee regardless of resource consumption
-” detailed answer 100 % correct :-”B
Rationale: The cloud value proposition includes trading capital expense (CAPEX) for variable
expense (OPEX). Instead of investing heavily in data centers and servers before knowing how
they will be used, customers pay only when they consume computing resources, aligning costs
with actual business needs.
Question 2
Which of the following is a design principle of the AWS Well-Architected Framework?
A) Stop guessing capacity needs
B) Use monolithic architectures for all workloads
C) Minimize automation to reduce complexity
D) Provision resources manually for better control
-” detailed answer 100 % correct :-”A
Rationale: "Stop guessing capacity" is one of the key cloud design principles. In the cloud, you
can scale capacity based on actual demand rather than forecasting, eliminating the risk of over-
provisioning or under-provisioning.

Question 3
A startup is building a new mobile application and expects highly variable traffic patterns. They
want to minimize costs while maintaining performance during traffic spikes. Which cloud
characteristic best addresses this requirement?
A) High availability
B) Elasticity
C) Global reach
D) Sustainability
-” detailed answer 100 % correct :-”B
Rationale: Elasticity enables systems to automatically scale resources up or down based on
demand. This allows the startup to handle traffic spikes without over-provisioning, optimizing
costs while maintaining performance.
Question 4
The AWS Cloud Adoption Framework (AWS CAF) provides guidance for organizations planning
cloud migration. How many perspectives does the AWS CAF include, and which of the following
is one of them?
A) 5 perspectives; Financial perspective
B) 6 perspectives; Governance perspective
C) 4 perspectives; Technical perspective
D) 6 perspectives; Development perspective
-” detailed answer 100 % correct :-”B
Rationale: The AWS CAF groups its guidance into six perspectives: Business, People,
Governance, Platform, Security, and Operations. The Governance perspective focuses on
aligning cloud strategy with business goals and managing risk.
Question 5
Which of the following is a benefit of the economies of scale provided by AWS?
A) Each customer must negotiate individual hardware pricing with vendors
B) AWS passes on cost savings from massive scale to customers through lower pay-as-you-go
, 4
prices
C) Customers receive dedicated physical servers at no additional cost
D) AWS charges premium prices for all services regardless of usage
-” detailed answer 100 % correct :-”B
Rationale: AWS achieves economies of scale by aggregating demand from hundreds of
thousands of customers, allowing them to achieve lower costs than any single customer could
achieve independently. These savings are passed on to customers through lower variable costs.
Question 6
A company is evaluating whether to migrate a legacy application to AWS. The application has
predictable, steady-state usage. Which pricing model would be MOST cost-effective for this
workload?
A) On-Demand Instances
B) Spot Instances
C) Reserved Instances
D) Savings Plans only
-” detailed answer 100 % correct :-”C
Rationale: Reserved Instances provide significant discounts (up to 75%) compared to On-
Demand pricing for workloads with predictable, steady-state usage. For applications with
consistent capacity requirements, Reserved Instances offer the best cost optimization.
Question 7
What is the primary purpose of the AWS Well-Architected Framework?
A) To provide a certification path for AWS professionals
B) To offer architectural best practices for designing and operating workloads in the cloud
C) To replace the need for security assessments
D) To automatically deploy infrastructure without user input
-” detailed answer 100 % correct :-”B
Rationale: The AWS Well-Architected Framework provides architectural best practices across six
pillars to help customers build secure, high-performing, resilient, and efficient infrastructure.
