How many questions are on CLF-C02?

65, of which 50 count toward your score. The other 15 are unscored questions AWS is trialling for future use, and they aren't identified on the exam.

What score do I need?

700 on a scale of 100 to 1,000. It's a scaled score, so it isn't the same as getting 70% of questions right — the number you need depends on the difficulty of the form you're given.

Do I have to pass every domain?

No. AWS uses a compensatory model, so only your overall score decides the result.

Do I need to know how to code?

No. AWS's exam guide explicitly lists coding as out of scope for this candidate, along with designing architecture, troubleshooting, implementation, and load and performance testing.

How much AWS experience do I need?

The target candidate has up to six months of exposure to AWS design, implementation or operations — or works alongside people in AWS roles.

Should I take CLF-C02 before SAA-C03?

Not necessarily. Cloud Practitioner isn't a prerequisite for the associate exams, and people who already build on AWS often skip it. It earns its place if you need to demonstrate cloud literacy rather than build skill.

Are these real exam questions?

No. Every item is original, written against AWS's published task statements and kept inside the in-scope service list. Sites selling recalled questions put your certification at risk as well as their own.

What can I do without paying?

Untimed practice across all four domains, with every question explained. Timed mocks, a scaled score and your readiness range need a subscription.

Is Acedify affiliated with AWS?

No. We're independent and we don't administer this exam.

The entry AWS exam, practiced against its own guide

Four domains, weighted the way AWS weights them. 50 questions count toward your score and 15 don't. Multiple-response items enforced properly, because that's where marks go missing. Free to start.

Domain mix matched to the official weighting, so a mock feels like the exam
Only in-scope services, because AWS publishes which ones those are
Readiness shown against 700, not as an invented percentage

CLF-C02Cloud Technology and ServicesHard

A company transfers a large, steady volume of data between its own datacenter and AWS every day. It needs consistent network performance and a connection that does not traverse the public internet.

Which service meets both requirements? Select one.

One choice only. Your earliest pick was dropped.

Scope

AWS says what's out of scope. Most prep ignores it.

The exam guide describes the target candidate as someone with up to six months of exposure to AWS, and then lists what that candidate is not expected to do. Coding is out of scope. So is designing cloud architecture, troubleshooting, implementation, and load and performance testing.

That matters because most free CLF-C02 material is written by people preparing for associate-level exams, and it pulls you into depth the exam never asks for.

What the exam expects, and what it does not
You're expected to	You're not expected to
Explain the value of the AWS Cloud	Write code
Understand the shared responsibility model	Design cloud architecture
Understand the Well-Architected Framework	Troubleshoot
Understand security best practices	Implement
Understand AWS costs, economics and billing	Run load and performance tests
Describe and position core compute, network, database and storage services
Identify AWS services for common use cases

AWS also publishes in-scope and out-of-scope service lists. Every question we write stays inside them, so you're never revising a service the exam won't ask about.

Scoring

50 questions count. 15 don't.

The exam has 65 questions, but only 50 affect your score. The other 15 are being trialled for future use, they aren't marked, and there's no way to tell which is which — so treat every question as if it counts.

Your result comes back as a scaled score from 100 to 1,000, and 700 passes. Because it's scaled, 700 isn't the same as answering 70% correctly. AWS also uses a compensatory model: you don't need to pass each domain, only the exam overall.

Unanswered questions are scored as incorrect and there's no penalty for guessing, so never leave one blank.

One domain well under the rest, and still a pass. AWS scores compensatorily: only the overall result decides it.

700 isn't 70%. AWS's scaled score isn't a percentage, and a weak domain doesn't fail you on its own.

AWS's score report may include a section-level breakdown, but its own guide advises caution in interpreting it. A domain score from a single sitting is a small sample, which is the same reason we report your readiness as a range rather than a number.

Hard

A company runs applications on Amazon EC2 instances and stores data in Amazon RDS databases. A reviewer asks which security responsibilities belong to the company in both cases.

Which two are the customer's responsibility for both services? Select two.

Applying operating system patches to the underlying instance.

Configuring security group rules that control network access.

Classifying the data and choosing how it is encrypted.

Maintaining the hypervisor and the physical host it runs on.

Security groups and data classification stay with the customer on both EC2 and RDS. OS patches move with the service, and the hypervisor is always AWS. Domain: Security and Compliance.

What you get back

Not a prediction. A distance from the line.

Your readiness is a range, because it's an inference from the questions you've answered rather than a result you've earned. For a certification the outcome is binary, so the only question is whether the whole range sits above 700. While it straddles the line, you're a coin flip, and we'll say so.

Domains

Four domains, and two of them are most of the exam

AWS publishes exact weights as a share of scored content, so our mocks can match the real mix rather than approximate it.

CLF-C02 domain weights
Domain	Weight
Cloud Technology and Services	34%
Security and Compliance	30%
Cloud Concepts	24%
Billing, Pricing, and Support	12%

Weights are exact rather than ranges, because AWS publishes them that way. Last checked against the exam guide on 13 September 2026.

Security and Compliance plus Cloud Technology and Services is 64% of the scored content. If you have a limited week, that's where it goes.

Billing, Pricing and Support is the smallest domain at 12% — around six scored questions. It's also the one people over-revise, because it's the easiest to make flashcards for.
