CLF-C02 Practice Questions (Free Sample)
Real CLF-C02 exam-style questions from our 500-question AWS Certified Cloud Practitioner bank, each with the correct answer and a detailed explanation.
Question 1 — CLF-C02
A startup wants to run a containerized web app without managing any servers or capacity planning, paying only for the compute it actually uses. Which AWS service best fits this requirement?
A
Amazon EC2 with an Auto Scaling group
B
AWS Fargate
C
Amazon Lightsail
D
Amazon EC2 Reserved Instances
Correct answer: B — Explanation
AWS Fargate is a serverless compute engine for containers — you pay per vCPU/memory consumed with no servers to provision or scale. EC2 (with or without Auto Scaling or Reserved Instances) still requires you to manage instance capacity. Lightsail offers simplified VPS-style servers but is not serverless and not container-native at scale.
Question 2Cloud ConceptsEasy
Which AWS service is an example of Infrastructure as a Service (IaaS)?
A
AWS Lambda
B
Amazon SageMaker
C
Amazon RDS
D
Amazon EC2
Show answer & explanation
Correct answer: D — Amazon EC2
IaaS provides fundamental compute, storage, and networking. EC2 provides virtual servers where the customer manages OS and above. Lambda is FaaS; SageMaker and RDS are higher-level managed services.
Question 3Cloud Technology and ServicesEasy
What type of database is Amazon ElastiCache?
A
Relational database
B
In-memory cache
C
NoSQL database
D
Data warehouse
Show answer & explanation
Correct answer: B — In-memory cache
ElastiCache provides in-memory caching (Redis or Memcached) to improve application performance by reducing database load.
Question 4Security and ComplianceMedium
A company wants to encrypt data stored in Amazon S3. Which AWS service can automatically encrypt new objects by default?
A
AWS KMS with S3 default bucket encryption (auto-encrypts new objects)
B
AWS WAF (web application firewall that inspects and filters inbound web requests)
C
AWS CloudHSM (dedicated hardware module for key storage)
D
Amazon GuardDuty (intelligent threat detection from logs)
Show answer & explanation
Correct answer: A — AWS KMS with S3 default bucket encryption (auto-encrypts new objects)
Amazon S3 supports default bucket encryption with AWS KMS (SSE-KMS), which automatically encrypts every new object written to the bucket without per-request configuration. AWS WAF filters inbound web traffic and does not encrypt stored data. AWS CloudHSM provides dedicated hardware for managing keys but does not itself enable S3 default encryption. Amazon GuardDuty detects threats by analyzing logs and network activity and performs no encryption.
Question 5Billing, Pricing, and SupportEasy
A company needs a dedicated Technical Account Manager (TAM) from AWS to help optimize their cloud environment. Which AWS Support plan(s) include this benefit?
A
AWS Partner Network (APN) program membership
B
Business Support plan (24/7 phone and chat included)
C
Developer Support plan (business-hours email access)
D
Enterprise On-Ramp and Enterprise Support plans
Show answer & explanation
Correct answer: D — Enterprise On-Ramp and Enterprise Support plans
A dedicated Technical Account Manager is available only with Enterprise On-Ramp Support (shared pool of TAMs) and Enterprise Support (dedicated TAM). Business Support includes a 24/7 support team and access to Trusted Advisor checks but not a TAM. Developer Support provides email-based support for development questions only. The AWS Partner Network is a partner program, not a customer support tier.
Question 6Cloud ConceptsMedium
An online education platform sees enrollment and course traffic surge every September at the start of the academic year, then taper off for the rest of the year. Which cloud characteristic saves them the most money compared to on-premises?
A
Reserved Instances for consistent, year-round workloads
B
Multi-Region high availability and redundancy
C
High availability and fault tolerance
D
Elasticity and pay-as-you-go pricing flexibility
Show answer & explanation
Correct answer: D — Elasticity and pay-as-you-go pricing flexibility
Elasticity is the ability to scale resources up or down automatically based on demand and to pay only for what is consumed. Cloud computing eliminates the need to over-provision for peak load, reducing waste during low-demand periods. Reserved Instances are a pricing model, not a scaling benefit. High availability and fault tolerance describe reliability features, not cost-efficiency through variable capacity. Multi-Region redundancy addresses disaster recovery, not elastic scaling.
Question 7Cloud Technology and ServicesMedium
A company stores large datasets that are rarely accessed - typically only once per quarter - but must be retrievable within milliseconds when needed. Which S3 storage class provides the lowest cost for this access pattern?
A
S3 Standard-Infrequent Access
B
S3 Intelligent-Tiering
C
S3 Standard
D
S3 Glacier Instant Retrieval
Show answer & explanation
Correct answer: D — S3 Glacier Instant Retrieval
Amazon S3 Glacier Instant Retrieval is designed for data accessed infrequently (roughly once per quarter) but requiring millisecond retrieval. It offers lower storage cost than Standard-IA while maintaining instant access. S3 Standard is optimized for frequently accessed data. S3 Standard-IA suits monthly access but costs more per GB than Glacier Instant Retrieval. S3 Glacier Flexible Retrieval is cheaper still but takes minutes to hours to restore, which does not meet the millisecond requirement.
Question 8Security and ComplianceHard
A company wants to ensure that no one can delete objects from an S3 bucket for 1 year after they are uploaded, for compliance reasons. Which S3 feature should be used?
A
MFA Delete
B
Versioning
C
Object Lock in compliance mode
D
Object Lock in governance mode
Show answer & explanation
Correct answer: C — Object Lock in compliance mode
Object Lock compliance mode prevents any user (including root) from deleting or overwriting an object for the specified retention period.
Question 9Billing, Pricing, and SupportMedium
A company has a workload that runs 12 hours per day. They are considering a 1-year Compute Savings Plan. How is the discount applied?
A
Commit to a consistent hourly spend for 1 or 3 years in exchange for a discounted rate
B
Commitment measured in instance hours per month, locked to specific instance families
C
Savings are measured by vCPU count across a single designated AWS Region
D
The discount applies after monthly billing usage passes a defined threshold
Show answer & explanation
Correct answer: A — Commit to a consistent hourly spend for 1 or 3 years in exchange for a discounted rate
AWS Savings Plans offer significant discounts (up to 72%) on compute usage in exchange for a commitment to a consistent spend (dollars per hour) for 1 or 3 years. They apply automatically to any EC2 instance type, size, OS, and Region (for Compute Savings Plans). Savings Plans are not tied to vCPU counts or minimum monthly billing thresholds. Reserved Instances require specifying instance type and Region but offer similar discount levels.
Question 10Cloud ConceptsHard
A company wants to deploy a multi-Region application with active-active failover. Which characteristic of AWS global infrastructure enables this?
A
CloudFront edge locations caching content at the network edge for latency reduction
B
Multiple Availability Zones within the same single AWS Region boundary
C
Independent AWS Regions connected by a fast private global network backbone
D
AWS Local Zones positioned near major metropolitan population centers
Show answer & explanation
Correct answer: C — Independent AWS Regions connected by a fast private global network backbone
Each Region is independent, but the AWS global network backbone provides high-bandwidth, low-latency connectivity between Regions for active-active setups.

What is the CLF-C02 passing score?
The CLF-C02 passing score is 700 out of 1000. That maps to roughly 70% of scored questions correct. AWS uses scaled scoring, so the exact number of correct answers required is not published.
How long does it take to prepare for CLF-C02?
Most candidates prepare in 3–6 weeks studying 1 hour per day. Review the four exam domains, learn the core compute/storage/database/networking services, understand the shared responsibility model, and complete at least two full mock exams.
How long is the AWS Cloud Practitioner certification valid?
CLF-C02 is valid for 3 years. You can recertify by passing any current AWS exam in your track or by retaking the Cloud Practitioner exam before it expires.
