YOUR CLF-C02 LEARNING MAP
Know what to learn—and how to recognize it in a question.
The percentages show the scored-content weighting in the CLF-C02 exam guide. Use the focus and question lens to connect service facts to exam scenarios.
Security and Compliance
Shared responsibility, identity, protection, detection, and governance.
QUESTION LENS
Who is responsible, and which control matches the threat or evidence?
Cloud Technology and Services
Compute, storage, databases, networking, integration, and analytics.
QUESTION LENS
Which service fits the workload with the least unnecessary operations?
Billing, Pricing, and Support
Purchase models, cost tools, billing structure, and support plans.
QUESTION LENS
Is the requirement to estimate, analyze, alert, optimize, or get support?

Welcome to Daily Prep
Start here
Use this roadmap as a short daily review, then confirm changing service details in current AWS documentation.
Key points
- The roadmap follows the four CLF-C02 domains.
- Previously unlocked lessons never close.
- Practice scores and this learning roadmap are independent.
MEMORY CUE
Small, repeated reviews beat one long cram session.
CLF-C02 exam snapshot
Start here
The exam has 65 questions and a 90-minute appointment, with both multiple-choice and multiple-response items.
Key points
- AWS reports a scaled score; the commonly published passing score is 700 out of 1000.
- Some questions are unscored and are not identified during the exam.
- There is no penalty for guessing, so answer every item.
MEMORY CUE
65 questions - 90 minutes - answer every item.
A reliable question method
Start here
Identify the requirement before comparing services. Most distractors solve a different category of problem.
Key points
- Underline cues such as lowest cost, least operations, highest availability, and fastest migration.
- Eliminate services outside the requested category.
- Prefer managed or serverless options when the prompt emphasizes less administration.
- Watch scope words: global, Region, Availability Zone, and edge location.
MEMORY CUE
Classify the need first; choose the service second.
Cloud value and economics
Cloud Concepts
Cloud value comes from speed, flexible capacity, global reach, and consumption-based economics.
Key points
- Agility means provisioning and experimenting quickly.
- Elasticity adds or removes resources with demand; scalability is the ability to grow capacity.
- CapEx becomes variable OpEx, reducing large upfront data-center purchases.
- Economies of scale can lower variable cost.
MEMORY CUE
Elasticity follows demand; scalability supports growth.
Regions, AZs, and edge locations
Cloud Concepts
AWS infrastructure scopes solve different latency, resilience, and compliance needs.
Key points
- A Region is a separate geographic area containing multiple Availability Zones.
- An AZ contains one or more discrete data centers; Multi-AZ designs improve availability.
- Edge locations bring CloudFront content and Route 53 responses closer to users.
- Local Zones, Wavelength, and Outposts address specialized low-latency or hybrid needs.
MEMORY CUE
Region = geography, AZ = resilience, edge = proximity.
