How to Pass AWS Cloud Practitioner (CLF-C02) in 15 Days: 2026 Roadmap

A structured 15-day study plan for the AWS Certified Cloud Practitioner CLF-C02 exam. Covers all four domains, daily tasks, top services to memorize, free resources, and a practice-question strategy that gets you to 700+ on exam day.

The AWS Certified Cloud Practitioner (CLF-C02) is the most popular entry-level cloud certification in the world. It proves you understand core AWS services, security fundamentals, billing concepts, and the business value of cloud computing. Whether you are pivoting into tech, adding a credential before tackling the Solutions Architect Associate, or validating cloud knowledge for a non-technical role, the CLF-C02 is the fastest way to earn an AWS badge in 2026.

This guide gives you a concrete 15-day roadmap — no fluff, no vague "study until you feel ready." Each day maps to a specific topic, a set of tasks, and a target number of practice questions. If you follow this plan and score 85%+ on practice exams consistently, you will pass.

Exam Overview

Before you start studying, understand exactly what you are signing up for. The CLF-C02 replaced the CLF-C01 in September 2023 and remains the current version through 2026. Here are the key logistics:

Detail Value
Exam Code CLF-C02
Total Questions 65 (50 scored, 15 unscored)
Time Limit 90 minutes
Passing Score 700 out of 1000 (scaled)
Exam Cost $100 USD
Delivery Pearson VUE (testing center or online proctored)
Question Types Multiple choice and multiple response
Validity 3 years

Key point: 15 of the 65 questions are unscored experimental questions. You will not know which ones they are, so treat every question as if it counts. The 90-minute time limit is generous — most candidates finish in 40 to 50 minutes. Use the extra time to review flagged questions.

The Four Exam Domains

The CLF-C02 blueprint distributes questions across four domains. Understanding these weights tells you exactly where to invest your study hours:

Domain Weight Approx. Scored Questions
1. Cloud Concepts 24% ~12
2. Security and Compliance 30% ~15
3. Cloud Technology and Services 34% ~17
4. Billing, Pricing, and Support 12% ~6

Domain 3 (Cloud Technology) is the largest domain at 34%. It requires you to know dozens of AWS services, what they do, and when to pick one over another. Domain 2 (Security) at 30% is the second-heaviest and focuses on the Shared Responsibility Model, IAM, encryption, and compliance. Together these two domains account for 64% of your scored questions — they must be your primary study focus.

15-Day Coach Study Plan

This plan assumes 2 to 3 hours of study per day. If you have prior IT or cloud experience, you can compress Days 1 through 3 into a single day. If you are brand new to cloud, consider extending to 20 days by giving yourself extra time on Domain 3.

Coach Tip: The total across 15 days is roughly 400 practice questions. Research shows that active recall (answering questions) is 2 to 3 times more effective than passive reading. Prioritize practice over re-watching videos.

Exam Day Tips

  • Read every word in the question. CLF-C02 questions often include qualifiers like "most cost-effective" or "with the LEAST operational overhead" that change the correct answer.
  • Eliminate two answers first. Most questions have two clearly wrong options and two plausible ones. Get to a 50/50 decision quickly.
  • Flag and move on. Do not spend more than 90 seconds on any question. Flag it and come back — you have plenty of time.
  • Trust your preparation. If you are scoring 85%+ on CertLand practice exams, you are ready. The real exam is not harder than good practice questions.

The AWS Cloud Practitioner is your entry point into the AWS ecosystem. Pass it in 15 days, then use the momentum to tackle the Solutions Architect Associate. Good luck — and start your practice on CertLand today.
