Free AWS Cloud Practitioner (CLF-C02) practice test

The AWS Certified Cloud Practitioner (CLF-C02) validates cloud literacy: what the cloud is good for, how AWS secures and prices it, and which core services solve which problems. This site gives you 354 original practice questions in the exam's real formats, free and without an account.

The real exam is multiple choice and multiple response only, and so is our simulator: 65 questions in 90 timed minutes, scored on the real 100 to 1,000 scale with the 700 pass line. Every topic links into the free 13-hour freeCodeCamp course at the matching chapter.

Practice questions from this bank

Sample question 1 · CLF-C02 · Cloud Concepts

A retail company currently buys servers every three years and pays for them up front. After moving its workloads to AWS, how does the company's cost structure change?

  1. ACompute costs become a fixed annual fee that is set at migration
  2. BHardware costs shift into per-user software licensing charges
  3. CLarge capital purchases are replaced by operational expenses that vary with usage
  4. DVariable operating costs are consolidated into a single upfront capital payment
Show answer and explanation

C. Large capital purchases are replaced by operational expenses that vary with usage

Moving to AWS trades capital expense for variable operational expense: the company pays for what it uses instead of buying hardware years in advance. Costs are not fixed annually and do not become an upfront payment; they track actual consumption.

Sample question 2 · CLF-C02 · Security and Compliance

Under the AWS shared responsibility model, which task remains an AWS responsibility no matter which service a customer uses?

  1. AApplying security patches to guest operating systems
  2. BConfiguring bucket policies that restrict object access
  3. CControlling physical access to data center facilities
  4. DRotating the access keys assigned to IAM users
Show answer and explanation

C. Controlling physical access to data center facilities

AWS is responsible for security OF the cloud, which includes the physical facilities, hardware, and global infrastructure. Guest OS patching, bucket policies, and credential rotation all sit with the customer because they involve what the customer runs and configures in the cloud.

Sample question 3 · CLF-C02 · Cloud Technology and Services

Which statement describes an Availability Zone within the AWS global infrastructure?

  1. AA geographic area that contains several independent AWS Regions
  2. BA logically isolated section of a network defined inside a VPC
  3. COne or more discrete data centers with independent power inside a Region
  4. DA worldwide set of caching endpoints used for content delivery
Show answer and explanation

C. One or more discrete data centers with independent power inside a Region

An Availability Zone consists of one or more discrete data centers with independent power, cooling, and networking inside a Region. Regions contain Availability Zones, not the reverse, and the caching-endpoint description refers to edge locations.

Sample question 4 · CLF-C02 · Billing, Pricing, and Support

A finance analyst wants an interactive view of the past 12 months of AWS spend, grouped by service, along with a forecast of the next three months. Which tool should the analyst use?

  1. AAWS Pricing Calculator
  2. BAWS Cost Explorer
  3. CAWS Budgets
  4. DAWS Cost and Usage Report
Show answer and explanation

B. AWS Cost Explorer

Cost Explorer provides interactive charts of historical spend with grouping, filtering, and built-in forecasting. The Pricing Calculator estimates planned workloads that are not running yet, Budgets sends threshold alerts, and the Cost and Usage Report is a raw data export rather than a visualization tool.

Sample question 5 · CLF-C02 · Cloud Concepts

An on-premises team must order hardware months before each product launch and usually ends up over-provisioned or short of capacity. What changes when the launch runs on AWS instead?

  1. AAWS sizes the launch environment from a submitted traffic forecast and pre-allocates it before the event
  2. BA fixed block of launch capacity must be reserved up front and is billed whether or not it is used
  3. CHardware requests are fulfilled from AWS inventory after a lead time of several days
  4. DCapacity can be provisioned to match live demand and adjusted afterward
Show answer and explanation

D. Capacity can be provisioned to match live demand and adjusted afterward

The core change is that you stop guessing capacity: resources are provisioned to match observed demand and resized in minutes as it shifts. AWS does not pre-allocate an environment from a submitted forecast on the customer's behalf, provisioning has no multi-day lead time, and reserving a fixed pre-paid block is an optional pricing choice rather than a requirement for launch capacity.

Sample question 6 · CLF-C02 · Security and Compliance

A healthcare company must show a regulator that its patient portal hosted on AWS meets industry requirements. Which statement reflects how compliance works in this situation?

  1. AWorkloads inherit the compliance status of the AWS services they run on, so no separate assessment is needed
  2. BAWS attests to the infrastructure, while the company must show its own workload handles data compliantly
  3. CThe regulator must obtain permission from AWS before it can audit a workload hosted in an AWS Region
  4. DResponsibility for meeting the requirements transfers to AWS once the company signs the applicable agreement
Show answer and explanation

B. AWS attests to the infrastructure, while the company must show its own workload handles data compliantly

Compliance is shared: AWS provides attestations for the cloud infrastructure, and customers remain accountable for configuring and operating their workloads to meet the applicable requirements. Running on certified infrastructure does not by itself make an application compliant.

Sample question 7 · CLF-C02 · Cloud Technology and Services

A media company keeps quarterly compliance reports in Amazon S3. The files are read only a few times per year, must be available within milliseconds when requested, and must survive the loss of an Availability Zone. Which storage class fits at the lowest cost?

  1. AS3 Standard
  2. BS3 One Zone-Infrequent Access
  3. CS3 Glacier Flexible Retrieval
  4. DS3 Standard-Infrequent Access
Show answer and explanation

D. S3 Standard-Infrequent Access

S3 Standard-IA offers millisecond access at a lower storage price for infrequently read data and replicates objects across multiple Availability Zones. One Zone-IA is cheaper still but stores data in a single AZ, and Glacier Flexible Retrieval takes minutes to hours to return objects.

Sample question 8 · CLF-C02 · Billing, Pricing, and Support

Which AWS Support plan includes a designated Technical Account Manager who provides proactive guidance and coordinates access to AWS subject-matter experts?

  1. ADeveloper
  2. BBusiness
  3. CEnterprise On-Ramp
  4. DEnterprise
Show answer and explanation

D. Enterprise

Enterprise Support assigns a designated Technical Account Manager to the account. Enterprise On-Ramp provides consultative access to a shared pool of technical account managers rather than a named individual, and Business and Developer include no TAM at all.

Common questions

How many questions are on the CLF-C02 exam?

65 questions in 90 minutes: 50 scored plus 15 unscored. The exam uses multiple-choice and multiple-response questions, and passing requires a scaled score of 700 on a 100 to 1,000 range.

Is Cloud Practitioner worth it before an associate cert?

It's the standard on-ramp: it proves cloud literacy for less technical roles and builds the vocabulary the associate exams assume. If you already administer AWS daily, some people skip straight to Solutions Architect Associate.

What are the CLF-C02 domains?

Cloud Concepts (24%), Security and Compliance (30%), Cloud Technology and Services (34%), and Billing, Pricing, and Support (12%). Our drills track your accuracy in each domain separately.
