AWS CLF-C02 Cloud Computing Exam
Questions 2026–2027 | Cloud
Practitioner Fundamentals Study Prep
with Answers & Explanations
1. A company operates an application on several physical servers in its own
data center. During periods of low demand, most of the servers remain
idle. Which AWS Cloud concept most directly addresses this inefficiency?
A. Fault isolation
B. Elasticity
C. Encryption
D. Data sovereignty
Answer: B. Elasticity
Rationale: Elasticity allows computing resources to increase or decrease in
response to changing demand. Instead of maintaining idle physical capacity, a
,workload can scale resources when needed and release them when demand
decreases.
2. A company wants to move from purchasing servers every five years to
paying for computing resources based on actual consumption. Which cloud
characteristic provides this benefit?
A. Fixed-capacity infrastructure
B. Pay-as-you-go pricing
C. Dedicated tenancy
D. Physical virtualization
Answer: B. Pay-as-you-go pricing
Rationale: AWS follows a consumption-based model for many services, allowing
customers to pay for resources they use rather than making large upfront
infrastructure purchases.
3. Which AWS Cloud benefit allows an organization to experiment with a new
application without purchasing physical servers first?
A. Agility
B. Data residency
C. Hardware ownership
D. Capital expenditure
Answer: A. Agility
Rationale: Cloud agility enables organizations to provision infrastructure
quickly, experiment, test, and deploy applications without lengthy physical
hardware procurement cycles.
, 4. A workload requires additional compute capacity during business hours and
significantly less capacity overnight. Which cloud principle should the
company use?
A. Elasticity
B. Durability
C. Encryption
D. Federation
Answer: A. Elasticity
Rationale: Elasticity is the ability to dynamically acquire and release resources
as workload requirements change.
5. Which statement best describes the AWS shared responsibility model?
A. AWS is responsible for all security controls in the customer environment.
B. Customers are responsible for all physical security controls.
C. AWS and customers have different security responsibilities depending on the
service.
D. Customers are responsible for securing AWS data centers.
Answer: C. AWS and customers have different security responsibilities
depending on the service.
Rationale: AWS secures the underlying infrastructure, while customers remain
responsible for security tasks within their control, such as data, identities,
configurations, and operating systems where applicable.
6. Which concept describes distributing applications across multiple
Availability Zones to reduce the effect of a single infrastructure failure?
A. Vertical scaling
B. High availability
, C. Data compression
D. Centralized processing
Answer: B. High availability
Rationale: Deploying resources across multiple Availability Zones helps
applications remain available if one Availability Zone experiences a failure.
7. A company wants an application to continue operating if one data center
facility experiences a hardware failure. Which AWS architectural approach
is most appropriate?
A. Deploy all resources in one Availability Zone
B. Deploy resources across multiple Availability Zones
C. Use a single larger instance
D. Disable automatic scaling
Answer: B. Deploy resources across multiple Availability Zones
Rationale: Availability Zones are separate infrastructure locations within an
AWS Region. Multi-AZ architectures improve resilience against failures affecting
a single Availability Zone.
8. Which statement best describes an AWS Region?
A. A single physical data center
B. A geographic area containing multiple isolated Availability Zones
C. A virtual private network
D. A single edge location
Answer: B. A geographic area containing multiple isolated Availability Zones
