AWS Cloud Practitioner Study Guide: A 4-Week Plan for CLF-C02

How to use this AWS Cloud Practitioner study guide

This AWS Cloud Practitioner study guide turns the official CLF-C02 exam guide into a week-by-week plan. The Cloud Practitioner is AWS's foundational certification. It checks that you understand what the AWS Cloud is, how its core services fit together, how security is shared between AWS and the customer, and how AWS pricing and support work. It does not ask you to build or code anything.

AWS says the target candidate has up to 6 months of exposure to AWS, but that experience is not required, and the exam suits people without an IT background. That makes it a good first cloud credential for students, career changers and non-technical staff who work alongside cloud teams.

The plan below assumes about 6 to 8 hours of study a week. If you already work with AWS, compress it into three weeks. If cloud computing is completely new to you, stretch it to five or six.

CLF-C02 exam facts you need before you start

• Exam code: CLF-C02.
• Questions: 65, of which 50 are scored and 15 are unscored. You cannot tell which ones are unscored.
• Time: 90 minutes.
• Question types: multiple choice (one correct answer out of four) and multiple response (two or more correct answers out of five or more options).
• Scoring: a scaled score from 100 to 1,000, with 700 needed to pass. Scoring is compensatory, so you need to pass the exam overall, not each domain.
• Guessing: unanswered questions are scored as incorrect and there is no penalty for guessing, so never leave a question blank.
• Delivery: a Pearson VUE test center or online proctored.
• Validity: 3 years.

The question counts are our own arithmetic from the published weights, not an AWS figure, and the exact mix can vary between exam forms.

The 4-week study plan mapped to the CLF-C02 domains

This plan follows the domain weights: the two biggest domains get the most time, and the last week is for practice tests and fixing gaps. Keep the official exam guide open as your checklist and tick off each task statement as you cover it.

Week 1: Cloud Concepts (24%)

• Learn the benefits of the AWS Cloud: paying only for what you use, scaling up and down, speed of deployment and global reach.
• Understand the six pillars of the AWS Well-Architected Framework and what each one is for.
• Learn the main migration ideas and cloud economics: fixed versus variable costs, and why rightsizing matters.
• Learn the AWS global infrastructure: Regions, Availability Zones and edge locations, and why you would deploy across several Availability Zones.
• End of week: a short untimed practice set on Cloud Concepts only.

Week 2: Security and Compliance (30%)

• Master the shared responsibility model. Know which tasks belong to AWS and which belong to the customer for different service types.
• Learn IAM: users, groups, roles and policies, the root user and why you protect it, and multi-factor authentication.
• Learn where to find compliance information and which services help with security monitoring, threat detection, encryption and key management.
• Open an AWS Free Tier account and create an IAM user with MFA yourself. Doing it once makes the questions far easier.
• End of week: a practice set covering weeks 1 and 2 together.

Week 3: Cloud Technology and Services (34%)

• Compute: EC2 and its purchasing options, containers and serverless options such as AWS Lambda.
• Storage: S3 and its storage classes, block storage and file storage, and when each fits.
• Databases: relational versus NoSQL options, and managed database services.
• Networking: VPCs, subnets, security groups, and content delivery and DNS services.
• Ways to work with AWS: the console, the CLI, SDKs and infrastructure as code.
• Hands-on: launch a small EC2 instance, create an S3 bucket, then delete both so you are not charged.

Week 4: Billing, Pricing, and Support (12%), then full practice exams

• Spend the first two days on pricing models (on-demand, reserved, savings plans, spot), billing and cost management tools, and the AWS Support plans and what each includes.
• Take a full timed practice exam: 65 questions in 90 minutes.
• Review every question, including the ones you got right, and note why each wrong option is wrong.
• Re-study your weakest domain, then take a second full practice exam two or three days later.
• Book the exam when you score comfortably above the passing standard on fresh practice questions, not ones you have already seen.

AWS Cloud Practitioner exam cost

The AWS Cloud Practitioner exam cost is USD 100 per attempt. AWS notes that additional costs and foreign exchange rates may apply depending on where you sit the exam, and that exam prices are updated at least once a year, in May, to reflect exchange rates. Local taxes can also be added at checkout.

Here is what the full cost can look like:

One benefit is worth planning around: AWS gives certified people access to a 50% discount voucher that can be used for recertification or any other AWS exam. If you plan to go on to the Solutions Architect - Associate, that voucher cuts the cost of your next exam. See the AWS certification path for which exam usually comes next.

You can reschedule an appointment up to twice, and only up to 24 hours before it starts. Cancelling later, or not turning up, means losing the fee.

What trips people up on CLF-C02

The Cloud Practitioner is an entry-level exam, but people still fail it, usually for predictable reasons.

• Similar-sounding services. Many questions ask you to pick the right service for a need. Make a one-line description of each in-scope service and quiz yourself on it until you can tell similar ones apart.
• The shared responsibility model. Questions often hinge on whether something is AWS's job or the customer's. The answer changes with the service type, so learn the principle, not a memorized list.
• Multiple-response questions. The question tells you how many answers to choose. Partly right answers do not earn credit, so read every option.
• Ignoring the small domain. Billing, Pricing, and Support is only 12%, but it is mostly straightforward recall. Those are points you can bank.
• Practising on remembered questions. A high score on a test you have taken three times measures memory, not readiness. Always judge readiness on questions you have not seen.

On exam day, flag any question that takes more than a minute and come back to it. 90 minutes for 65 questions leaves time for a review pass if you keep moving.

Is the AWS Cloud Practitioner worth it?

It depends on your goal. For someone with no cloud background, it gives a structured overview of AWS and a credential you can earn in weeks for a modest fee. For non-technical roles in sales, finance, procurement or project management, it shows you can follow technical conversations about AWS.

For engineers who already build on AWS, the Cloud Practitioner adds less. AWS itself recommends that people with no IT experience start here, while people with about a year of hands-on AWS work often go straight to the Solutions Architect - Associate.
