Sample CLF-C02 diagnostic questions

These are real items from the CLF-C02 bank, one from each of three domains, shown with their answers so you can see the format before you start. The diagnostic itself draws 24 questions from 65 CLF-C02 terms , and does not reveal answers until the end.

  1. Billing, Pricing, and Support

    A service that sets up and governs a secure, multi-account AWS environment with best practices.

    Which term does this describe?

    • ✓ AWS Control Tower
    • · AWS Organizations
    • · Total Cost of Ownership
    • · Reserved Instances

    Exam tip: Control Tower automates landing-zone setup on top of AWS Organizations.

  2. Security and Compliance

    Which best describes “AWS Config”?

    • ✓ A service that records and evaluates the configuration of AWS resources for compliance.
    • · An intelligent threat-detection service that continuously monitors for malicious activity.
    • · A managed service that protects applications against distributed denial-of-service (DDoS) attacks.
    • · A service that records account activity and API calls for governance, auditing, and compliance.

    Exam tip: Config tracks resource configuration changes over time and checks them against rules.

  3. Cloud Concepts

    Which best describes “CapEx vs OpEx”?

    • ✓ Capital expenditure (upfront purchases) versus operational expenditure (ongoing pay-as-you-go costs).
    • · The practice of running systems to deliver business value at the lowest price point.
    • · Designing systems to stay operational with minimal downtime even when components fail.
    • · Paying only for the resources you consume, with no long-term commitment required.

    Exam tip: The cloud shifts spending from CapEx to OpEx — a frequently tested distinction.

What the CLF-C02 diagnostic covers

The quiz mirrors the exam blueprint. Cloud Technology and Services carries the most weight on the real CLF-C02, at about 34% of the test, so it gets the most questions here; Billing, Pricing, and Support, at about 12%, gets the fewest, but never fewer than 3, because a band should never rest on a single question. The questions draw on the site's CLF-C02 term bank, so they measure how well you know the concepts and vocabulary the exam is built on. They are not full-length scenario items.

  1. Cloud Technology and Services

    34% of the exam

    Exam Domains

    Domain 3 — the largest domain: AWS global infrastructure (Regions, Availability Zones, edge locations) plus core compute, storage, database, networking, and management services.

    19 terms · 2 study sets

  2. Security and Compliance

    30% of the exam

    Exam Domains

    Domain 2 — the AWS shared responsibility model, security and compliance concepts, access management with IAM, and the AWS security services used to protect identities, data, and workloads.

    17 terms · 2 study sets

  3. Cloud Concepts

    24% of the exam

    Exam Domains

    Domain 1 — the fundamentals of cloud computing: the value of the AWS Cloud, service models (IaaS, PaaS, SaaS), the AWS Well-Architected Framework, cloud economics, and the benefits of cloud such as elasticity and agility.

    14 terms · 2 study sets

  4. Billing, Pricing, and Support

    12% of the exam

    Exam Domains

    Domain 4 — AWS pricing models, cost management tools, AWS Organizations and consolidated billing, the AWS Support plans, and the resources available to help you build and operate on AWS.

    15 terms · 2 study sets

How your result is scored

Each domain comes back as a band rather than a percentage: Needs work (under 50% correct), Developing (50% to 79%), or Solid (80% and up). A handful of questions per domain is enough evidence to say "this needs work"; it is not enough to trust a number like 67%, so we do not show one.

The study-first list ranks domains by the share of the exam each one puts at risk: its blueprint weight multiplied by the fraction you missed. On the CLF-C02 that maths has teeth, because the domains are not equal — Cloud Technology and Services is worth about 34% and Billing, Pricing, and Support about 12%, so half-knowing Cloud Technology and Services costs you roughly 17 points of the exam while barely knowing Billing, Pricing, and Support costs about 10. Up to three domains make the list; if all 4 come back Solid, the list is empty and the full-length mock exam is the next real test.

Every question you miss is written into that study set's flashcard deck as due now, so the review queue starts with your actual gaps — across the 2 study sets in Cloud Technology and Services alone, that is the difference between re-reading things you already know and drilling the ones you do not. Your attempts are kept in this browser (the last five), and a retake shows which domains moved up or down since last time.

This is a study map, not a prediction. The real CLF-C02 runs 65 questions in 90 minutes and is administered by Amazon Web Services (AWS); this is 24 untimed questions drawn from the same blueprint. No sample that short can estimate a result on it, and the site's own mock exam uses a 70% practice target rather than a pass prediction for the same reason.

What to do with your result

  1. Step 1

    Open your first focus domain

    Start with the top of the study-first list. Its study sets are linked right on the results screen; flashcards for the terms you missed are already due.

  2. Step 2

    Drill the set, then quiz it

    Flashcards build recall; the per-set quiz checks it with confusable distractors drawn from related terms.

  3. Step 3

    Retake, then take the mock exam

    After a study block, retake the diagnostic to see which bands moved. When the focus list is empty, the timed CLF-C02 mock exam is the next real test.

Frequently asked questions

How long is the CLF-C02 diagnostic quiz?
24 questions, untimed. Most people finish in about 8 minutes. Every domain gets at least 3 questions, and the rest are spread in proportion to each domain's weight on the real exam.
Does the result predict whether I will pass?
No. A 24-question sample can tell you which domains need work; it cannot estimate a real CLF-C02 result. Treat it as a study map, then measure progress with the full-length mock exam.
Where is my result stored?
In your browser only, using local storage. Nothing is uploaded and no account is needed. Retake the quiz later and the results screen compares the two attempts domain by domain.
What happens to the questions I miss?
Each missed term is scheduled as due in that study set's flashcards, so your next review session starts with exactly the gaps the diagnostic found.
