AWS Cloud Practitioner (CLF-C02) Exam Guide 2026 — Cost, Format, Passing Score

AWS Certified Cloud Practitioner (CLF-C02) is the foundational credential in the AWS certification path. It does not ask you to design an architecture or debug a Terraform plan — it asks whether you understand what AWS is, how the cloud value proposition works, and which service does roughly what. If you are new to AWS, in a non-technical role that touches cloud (sales, finance, project management), or preparing to climb toward Solutions Architect or Developer Associate, Cloud Practitioner is the sensible starting point.

This guide covers the exam format itself: cost, time, scoring, question types, retake rules, validity period, and what the exam actually tests. For the week-by-week study path, see the 4-week Cloud Practitioner study plan. For a fast final-review reference, see the Cloud Practitioner cheat sheet.

What Cloud Practitioner is (and is not)

Cloud Practitioner sits at the base of the AWS certification ladder, below the Associate tier (Solutions Architect, Developer, SysOps Administrator), the Professional tier, and the Specialty exams.

What Cloud Practitioner is:

• A conceptual credential. Expect questions on cloud value proposition, the AWS shared responsibility model, and pricing philosophy rather than hands-on configuration.
• A breadth exam. You need working familiarity with 20-plus AWS services well enough to recognize what each one is for, not how to configure it.
• Open to any background. AWS explicitly markets it toward both technical and non-technical roles — sales engineers and finance staff sit CLF-C02 alongside junior developers.

What Cloud Practitioner is not:

• Not an architecture exam. Solutions Architect Associate (SAA-C03) covers actual design trade-offs and is meaningfully harder.
• Not a hands-on exam. There are no CLI-output or YAML-interpretation questions like you will see on Associate-level exams.
• Not a coding exam. AWS Developer Associate (DVA-C02) is the credential that tests SDK usage and application code.

Exam format at a glance

90 minutes for 65 questions is about 83 seconds each — tighter than it sounds once you hit the scenario-style questions that run three or four sentences. Plan to move fast on the recall-style questions (service name matching, pricing model definitions) so you have slack for the handful of genuinely two-step scenario questions.

Cost, currency, and vouchers

CLF-C02 costs $100 USD, charged at booking. There is no standing discount for individuals, but AWS runs periodic 50%-off voucher programs through AWS re/Start, AWS Educate, university partnerships, and attendee perks at AWS conferences like re:Invent. Watch the AWS Certification site and your regional AWS user-group mailing list for these.

Pearson VUE converts the price to local currency at checkout in non-USD regions. VAT or local sales tax may apply on top of the $100 depending on your country.

Scoring and the passing score

Unlike some vendors, AWS publishes the passing score outright: 700 out of 1000. This is a scaled score, not a raw percentage — AWS converts your raw correct-answer count through a statistical model that accounts for question difficulty, so “700” does not mean “70% of 65 questions correct.” The exact conversion formula is not published.

Some of the 65 questions are unscored — AWS includes them to gather performance data for future exam versions, but does not disclose which ones, so treat every question as if it counts.

CertSharp's recommendation: score consistently above 85 percent on full-length 65-question timed mocks before booking. Because the scaled conversion is not linear and unscored items are invisible, a comfortable margin above the raw pass threshold protects you from a bad scaling day.

Question types you will see

CLF-C02 uses two question formats:

1. Multiple choice. The dominant format — a scenario or definitional stem, four options, one correct answer.
2. Multiple response. The stem says “select TWO” (occasionally three). Five or more options, exactly two or three correct. You must select the full correct set to earn the point — there is no partial credit.

There are no labs, no CLI output to interpret, and no drag-and-drop items on Cloud Practitioner. That level of hands-on testing starts at the Associate tier.

The four exam domains

AWS publishes four domains with their relative weights:

Domain 3 carries the largest weight — this is where the “name that service” questions live, covering compute, storage, networking, and database options. Domain 2 is close behind, and it is where most first-time candidates lose points: the shared responsibility model is tested from several angles, and it is easy to misjudge where AWS's responsibility ends and yours begins. For the concept in full, see AWS Shared Responsibility Model Explained.

Test center vs OnVUE online

Both delivery methods produce the same exam content and the same pass/fail outcome.

Pearson VUE test center is in-person. You arrive with valid ID, store your belongings in a locker, and sit at a provided workstation while the center staff proctor in person.

OnVUE online proctoring lets you test from home. You install the OnVUE application, complete an ID check and room scan on camera, and a remote proctor monitors you for the full 90 minutes. You need a stable connection, a single monitor, and a private room with a clear desk.

Which to choose: OnVUE saves travel time and is available around the clock in most regions, but any connectivity hiccup or background noise can trigger a proctor intervention. If your home setup is not private and quiet, book a test center slot instead — it removes that variable entirely.

How to register

1. Create or sign in to your AWS Certification account.
2. Select AWS Certified Cloud Practitioner and choose “Schedule this exam.”
3. Pick a delivery method: Pearson VUE test center or OnVUE online.
4. Choose an available date and time slot — OnVUE slots run 24/7 in most regions.
5. Pay the $100 fee (or apply a voucher code if you have one).
6. Save the confirmation email; it has your exam appointment details and any pre-exam requirements.

You can reschedule for free up to 24 hours before your appointment. Inside that window, you forfeit the exam fee.

ID and check-in rules

You need government-issued photo ID that matches the name on your AWS Certification account exactly. Test centers may ask for a second form of ID; OnVUE typically accepts one primary ID plus the on-camera identity verification built into the check-in flow.

For OnVUE, check-in opens 30 minutes before your slot. Expect a full room scan (walls, desk, ceiling) via your webcam. Clear your desk completely and remove watches, headphones, and any second screen. For test centers, arrive at least 15 minutes early; late arrivals beyond the grace period forfeit the appointment.

Retake policy

If you fail CLF-C02, AWS applies a flat 14-day wait before you can retake it — this does not escalate with repeated failures, unlike some other vendors. There is no cap on total lifetime attempts. Each retake costs the full $100 fee. AWS sends a section-level score breakdown after a fail, so use the wait to drill your weakest domain rather than re-studying everything evenly.

How long the cert lasts

Cloud Practitioner is valid 3 years from the pass date. Recertify by retaking the current version of CLF-C02 within the renewal window, or read on — there is a way to extend your status without retaking the exact same exam.

Recertification without retaking

AWS lets you extend your certified status early by passing a higher-level AWS certification before your Cloud Practitioner credential expires — for example, passing Solutions Architect Associate resets your 3-year clock without sitting CLF-C02 again. This matters for planning: if you intend to climb the AWS ladder anyway, your natural progression to Associate-level certs keeps you continuously certified without a separate Cloud Practitioner retake.

Prerequisites and recommended experience

Cloud Practitioner has no formal prerequisites and no required prior AWS certification. AWS recommends 6 months of foundational AWS Cloud exposure in any role — this can be hands-on, or it can be exposure through working alongside teams that use AWS.

If you have zero cloud background, plan on 3-4 weeks of focused study. If you already work with AWS in a non-certified capacity, 1-2 weeks of terminology and service-mapping review is often enough.
