AWS lists coding, designing cloud architecture, troubleshooting, and implementation as out of scope for CLF-C02 (exam guide). All 65 questions test whether you can match a plain business need to the AWS idea built for it. So the study plan is a recognition plan. Take the free CLF-C02 assessment before you study anything, spend four weeks on the four content domains in weight order at about 5 hours a week, and let the pairs you got wrong set the syllabus.
The exam measures four domains and scores one total
The official CLF-C02 exam guide lists four content domains, as shares of scored content:
- Cloud Concepts: 24%
- Security and Compliance: 30%
- Cloud Technology and Services: 34%
- Billing, Pricing, and Support: 12%
The guide also lists what the exam validates as a whole. It covers the value of the AWS Cloud, the shared responsibility model, the Well-Architected Framework, security best practices, AWS Cloud costs and billing practices, and the core compute, network, database, and storage services.
Format facts that shape the plan:
- You get 90 minutes for 65 questions, each either multiple choice (one correct answer) or multiple response (two or more correct out of five or more), at a Pearson VUE test center or online proctored (exam page).
- Only 50 questions affect your score. The other 15 are unscored and not identified. Unanswered questions count as incorrect, and there is no penalty for guessing, so answer every question (exam guide).
- Your result is a scaled score from 100 to 1,000, and 700 passes (exam guide).
- The exam uses a compensatory scoring model. You pass on the overall score, and you do not need a passing score in each section. The score report can include a table of section-level classifications, and the guide says to use caution when you interpret section-level feedback (exam guide).
The target candidate has up to 6 months of exposure to AWS Cloud and may have no IT background (exam page). If you work in sales, marketing, product, or project management and you are starting from zero, that is the exam AWS points you to. Recheck the exam page before you book, because details like the available languages change there. The Italian and German versions of the exam retire after December 31, 2026.
Take the free assessment first, and record the pairs
Take the free CLF-C02 assessment before you study. It is free, needs no card, and returns a Readiness Report with your top gaps. Answer it without looking anything up. For each question you get wrong, write down the pair in your own words: the service or idea you chose, and the one the question wanted.
The exam guide says the distractors "are generally plausible responses that match the content area" (exam guide). A plausible wrong answer names the pair that confused you, and that pair is the part of the syllabus that matters for you.
Do not skip Billing, Pricing, and Support because it is only 12%. Its distinctions (Savings Plans versus Reserved Instances, AWS Budgets versus Cost Explorer, which Support option covers what) are exactly the kind of pair that is easy to mix up.
Four weeks, about 5 hours a week, in weight order
This plan assumes about 5 hours a week. The two heaviest domains (Security and Compliance at 30%, Cloud Technology and Services at 34%) each get a full week. Cloud Concepts comes first because every later domain uses its vocabulary, and Billing comes last because its tools build on the services you meet in weeks 2 and 3.
- Week 1: Cloud Concepts (24%). The benefits of the AWS Cloud, the Well-Architected pillars, migration strategies, and cloud economics. Done when you can explain each in plain language without notes.
- Week 2: Security and Compliance (30%). The shared responsibility model, security and compliance concepts, access management, and security components. Done when you can say who handles what on Amazon EC2 versus AWS Lambda, and name the MFA and root-user protections for a new account.
- Week 3: Cloud Technology and Services (34%). Deployment models, global infrastructure, and the compute, database, network, storage, and analytics services. Done when you can place Regions, Availability Zones, and edge locations, and match a compute, database, network, or storage service to a use case.
- Week 4: Billing, Pricing, and Support (12%), then mixed review and retests. Done when you can pick a compute purchasing option, a cost tool, and a Support option for a stated need.
Cloud Technology and Services has eight task statements in the exam guide, more than any other domain. If the Readiness Report shows it is your weakest area, start it in week 2 alongside security.
If you have less than four weeks, keep the order and compress it. Do not drop the diagnostic or the final mixed retest. They are what tell you whether the compressed version worked.
Cloud Concepts (24%): match the benefit to the constraint in the stem
The domain 1 task statements ask you to define the benefits of the AWS Cloud, its design principles, the benefits and strategies for migration, and cloud economics (domain 1). In a benefit question, several options are true statements about AWS. The stem picks the answer by naming a constraint, a location, a budget, a traffic pattern, or a deadline, and you read for it before you read the options.
The constraints and the benefit they point to:
- Users are somewhere the company has no facility. The benefit is global infrastructure. AWS Regions give global reach without a local data center.
- The system must survive a failure in one place. That is high availability.
- Load grows and shrinks with demand. That is elasticity.
- The company wants to avoid capital expense or pay only for what it uses. That is consumption-based pricing. The cloud economics task statement covers it alongside fixed versus variable costs, rightsizing, and licensing choices such as bring-your-own-license.
- The question is about the cost advantage of a provider operating at massive scale. That is economies of scale.
The options that do not match the constraint are genuine AWS benefits, which is why they read as plausible. Each one answers a different constraint from the one in the stem.
The Well-Architected part names six pillars: operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability. The exam also asks you to identify the differences between the pillars (domain 1). Migration questions point at the AWS Cloud Adoption Framework, whose components the guide lists as reduced business risk, improved environmental, social, and governance performance, increased revenue, and increased operational efficiency.

Security and Compliance (30%): draw the responsibility line per service
The shared responsibility model is the first task statement of the domain, and the line it draws moves with the service you choose. AWS's model page makes the EC2 split explicit. You are responsible for the guest operating system, including updates and security patches, for the software you install on the instance, and for the security group configuration on each instance (AWS shared responsibility model). On every other service the line is set by what AWS runs for you, and that shift is what the questions test.
Three families fill the rest of the domain (domain 2 task statements):
- Access. Multi-factor authentication (MFA), IAM Identity Center, cross-account IAM roles, access keys, password policies, and credential storage. The root user has its own list of tasks and its own protection methods.
- Compliance. Where AWS compliance information lives (AWS Artifact is the example the guide gives), compliance needs by geography or industry, and encryption in transit or at rest.
- Security components. The services that surface security issues, such as AWS Trusted Advisor.
The access questions point at the IAM basics. Work through Getting started with IAM once. It covers who can sign in, how, and what they can do, which is what the access questions ask.
Cloud Technology and Services (34%): separate the tools that move workloads from the services that host them
This is the largest domain, with eight task statements, more than any other domain. It runs from the deployment models and the AWS global infrastructure to the compute, database, network, and storage services, AI/ML and analytics, and the remaining in-scope categories (domain 3). Every question here asks the same thing. Given a need, pick the service built for it.
Wrong answers cluster where a question describes a move, a migration, or a hybrid setup, and the options include services that would host the result but do not do the moving. The clearest example is database migration. Task statement 3.4 names the pair that handles it, AWS Database Migration Service (AWS DMS) and AWS Schema Conversion Tool (AWS SCT). If the stem wants existing records carried into AWS while schema differences between the source and target engines are handled, that pair is the answer. Amazon RDS and Amazon Aurora can host the destination, but they do not do the moving, so they are the close distractors.
Global infrastructure is its own task statement. Be able to define a Region, an Availability Zone, and an edge location, and say what a workload gains at each level.
The rest of the domain is the service list. The exam guide keeps the in-scope services organized by category. Write one sentence per service on the problem it solves, and the recognition part of the exam is mostly done.
Billing, Pricing, and Support (12%): learn the two pairs before anything else
This domain has three task statements (domain 4): compare the pricing models, understand the billing and cost management resources, and identify the technical resources and Support options. Two of them carry pairs the questions use directly.
AWS Budgets or Cost Explorer. If the stem wants a warning before or when spend passes a number, that is AWS Budgets. A cost budget sets a spending limit for services, and you get alerts when costs approach or exceed your defined threshold (AWS Budgets). If the stem wants to see where money went or where it is heading, that is Cost Explorer. It shows up to the last 13 months of cost data and forecasts the next 18 months (Cost Explorer).
Savings Plans or Reserved Instances. Both trade a 1-year or 3-year commitment for a lower price. The difference is flexibility. Compute Savings Plans commit to an amount of compute usage measured in dollars per hour, instead of a specific instance configuration. In AWS's comparison, they automatically apply pricing to any instance family, any instance size, and any tenancy or operating system, across AWS Regions, to Amazon ECS and Amazon EKS using Fargate, and to Lambda. Reserved Instances show no flexibility on those rows. Convertible RIs can be exchanged manually, and Savings Plans cannot be cancelled during the term (Savings Plans and Reserved Instances). If the stem says the workload will change instance types or move to containers or serverless, the answer leans toward Savings Plans.
For the Support side, the guide lists the options: customer service and communities, Basic Support, AWS Business Support+, AWS Enterprise Support, and AWS Unified Operations (domain 4). A Support question names a need and asks which option covers it.
Create a budget in your practice account before you launch anything for the other domains. Anything you create can incur charges, so delete what you create when you finish.
How you know a weak area is fixed
Reading a service description after a wrong answer is not the same as picking that service from four plausible options next time. At the end of each week, check the domain again with questions you have not seen, and see whether the pairs you recorded still catch you. A weak area is fixed when the pair stops showing up even when the wording changes.
CramHQ's CLF-C02 path is free, with no card required. The free assessment returns a Readiness Report with your top gaps, and the full CLF-C02 course supplies the weekly retests. It includes original CLF-C02 practice questions with hints and explanations, flashcards, 5 practice tests, a Final Timed Simulation, and targeted Pass Plan repairs.
The readiness call: book or spend a few more days
In the last days, take a fresh mixed timed set from the course, and work the AWS exam prep resources linked from the exam page, including the AWS Certification Official Practice Question Set and the Official Pretest. Count only questions you have not seen before, and note which domain each wrong answer comes from.
The official score report can include section-level feedback, and the exam guide says to use caution when interpreting it. The same applies to practice. One weak domain on one set is not a verdict. Book the exam when your wrong answers are scattered across the domains. Spend a few more days when one pair keeps coming back.
Take the free CLF-C02 assessment if you have not taken it yet. Its Readiness Report is where the four weeks start, and the mixed set decides when you book.
