Cloud Practitioner (CLF-C02) exam. Each question is meticulously designed to reflect the actual
exam's difficulty, wording, and topic distribution across all four domains:
1. Cloud Concepts (24% of exam)
2. Security and Compliance (30% of exam)
3. Technology (34% of exam)
4. Billing, Pricing, and Support (12% of exam)
Domain 1: Cloud Concepts (Questions 1–12)
1. Which of the following is a benefit of moving from an on-premises data center to the AWS Cloud?
A. Fixed monthly infrastructure costs
B. Trade capital expense for variable expense
C. Elimination of all security risks
, D. Mandatory reduction in staff headcount
Rationale: AWS replaces upfront capital expenditure (servers, racks) with pay-as-you-go variable
expense.
2. Which design principle allows AWS Cloud infrastructure to withstand failures without significant
downtime?
A. Vertical scaling
B. High availability
C. Single point of failure
D. Manual failover
Rationale: High availability uses redundant components across Availability Zones to maintain
operations despite component failure.
3. What is the primary advantage of AWS’s global infrastructure?
A. Single data center location for compliance
B. Ability to deploy workloads closer to end users
C. Guaranteed zero latency worldwide
D. Automatic code compilation
Rationale: AWS Regions and Edge Locations allow you to place applications near users, reducing
latency.
4. Which AWS service provides a virtual network environment in the cloud?
A. Amazon S3
B. AWS Lambda
C. Amazon VPC
D. Amazon RDS
,Rationale: Amazon Virtual Private Cloud (VPC) lets you provision logically isolated sections of the
AWS Cloud.
5. What is the term for the ability to increase or decrease AWS resources automatically based on demand?
A. Manual scaling
B. Elasticity
C. Fixed provisioning
D. Reserved capacity
Rationale: Elasticity automatically adjusts resources to match current workload, optimizing cost
and performance.
6. A company wants to run a short-term batch job for 20 minutes. Which pricing model is most cost-
effective?
A. 1-year All Upfront Reserved Instance
B. On-Demand Instance
C. 3-year Partial Upfront Reserved Instance

and RDS.
8. What does “pay-as-you-go” pricing enable in AWS?
, A. Long-term capacity planning only
B. No upfront costs and pay only for what you use
C. Fixed monthly bill regardless of usage
D. Free data transfer between all regions

resources.
9. Which AWS service is used to launch and manage virtual servers?
A. AWS Lambda
B. Amazon EC2
C. Amazon S3
D. Amazon DynamoDB
Rationale: Amazon Elastic Compute Cloud (EC2) provides resizable virtual machines.
10. A startup expects unpredictable traffic spikes. Which cloud characteristic helps them avoid over-
provisioning?
A. Elasticity
B. Security groups
C. Edge locations
D. Availability Zones
Rationale: Elasticity automatically adds or removes capacity as traffic changes, preventing over-
provisioning.
11. Which statement best describes the concept of “scaling out”?
A. Replacing a server with a larger server
B. Adding more instances to handle load
