A question you'd getAWS SAA-C03
Domain 3 · Databases

Which AWS service provides a fully managed NoSQL database with single-digit millisecond latency at any scale?

AAmazon RDS
BAmazon DynamoDBCorrect
CAmazon Redshift
Why

DynamoDB is AWS's managed NoSQL store, built for consistent single-digit-millisecond reads at any scale. RDS and Aurora are relational; Redshift is built for analytics, not low-latency lookups.

№ 02How it worksFrom today to exam day

Four steps. Nothing to buy first.

There's no question bank to purchase and no course to hunt down. Prepa builds the syllabus, the lessons, the labs and the questions around the exam you're actually sitting.

Start free — no card

01

Tell Prepa which exam you're taking

Pick one of 20 certifications, describe any other exam, or upload your own study notes. About thirty seconds later you have a full syllabus, weighted exactly like the real test.

02

Learn each topic, then go and build it

Lessons teach the topic properly — decision tables, examiner traps, the facts worth memorising. Then a hands-on lab drops you into a real cloud console to do it for yourself.

03

Practise where you're actually weak

Every session brings fresh questions aimed at the domains dragging your score down, with explanations you can check and a tutor for the follow-up questions.

04

Book the exam when the score says go

Sit timed, full-length mocks in the real question formats. Your readiness score and per-domain mastery tell you when you're ready — and the daily plan gets you there by your exam date.

№ 03What you getEverything in one subscription
Lessons

Learn the syllabus, not just the questions

Your exam's full syllabus, weighted exactly like the real test, taught with decision tables, the traps examiners love, and the facts worth memorising — then a knowledge check that proves it stuck.

Practice

Drill the topics you keep getting wrong

Fresh exam-style questions every session, aimed at your weakest domains. The more you practise, the more the questions target what's actually holding your score down.

Hands-on labs

Build it for real, in a real console

Guided labs you run in your own free-tier cloud account — build the VPC, deploy the pipeline. Checkpoints confirm you did it, and a cleanup list means nothing keeps running and nothing gets billed.

Mock exams

Sit the real thing before you sit the real thing

Timed, full-length mocks in your exam's actual question formats — multiple choice, drag-to-order, matching, Yes/No grids, even typed CLI commands. No surprises on the day.

Readiness score

Know when you're ready to book

One number that climbs as you improve, backed by mastery tracking in every exam domain. Book with evidence instead of a gut feeling.

Study plan

Know what to study today

Set your exam date and Prepa builds the daily plan — weighted to your weak areas, rebalanced when life gets in the way, and honest with you about pace.

AI tutor

Get an answer to 'but why?'

Every question and lesson has a tutor attached. Ask a follow-up, ask for a mnemonic, ask for it again but simpler — until it actually makes sense.

Flashcards

Stop forgetting what you already learned

Questions you miss and key facts from your lessons turn into flashcards automatically, scheduled to reappear right before you'd have forgotten them.

Verified answers

Never revise from a wrong answer

A second, independent AI answers every multiple-choice question with the answer key hidden. If it disagrees, the question is thrown out before it ever reaches you.

Real sources

Check the answer against the vendor

Explanations link to the official documentation — AWS, Microsoft Learn, Google Cloud, Cisco. Links anywhere else, or links that have gone dead, are stripped before you see them.

№ 04Why you can trust itHow every answer is checked

An AI wrote your questions. So we check them.

Nothing hurts your score like revising a wrong answer for a week. Three checks stand between a new question and your screen — and any one of them will throw it out.

01

Written from the official exam blueprint

Questions follow your exam's published domains and weightings — the vendor's own outline, not somebody's guess at what might come up.

02

Answered again by a second AI

A different AI answers the question with the answer key hidden from it. If the two don't agree, the question is thrown out. You only ever see the ones they both got right.

03

Backed by a link you can check yourself

Every explanation cites the vendor's own documentation, and we test the link works before you see it. Made-up URLs get stripped out.

Still think a question is wrong? Flag it. We re-check it independently, and if the check agrees with you it comes straight out of your review queue.

Dumps ask you to trust them. Prepa shows its work.

A question bank sells you someone else's answers, frozen the day they were written. Here's what you get instead.

№ 08Questions, answeredBefore you sign up

What people ask before they start.

Anything still unclear? You can try the whole thing free before you decide — no card, nothing to cancel.

How do I know the answer keys are right?

Every multiple-choice question is answered a second time by a separate, independent model that never sees the answer key — it sits the question cold. If its answer doesn't match, the question is discarded and you never see it. Explanations link to the vendor's own documentation, and those links are checked before delivery. If a question still looks wrong, flag it: it gets independently re-checked and removed from your review queue if the check agrees with you.

Which certification exams does Prepa cover?

Prepa ships 20 certifications built from their official exam blueprints — including AWS Certified Solutions Architect – Associate, AWS Certified Cloud Practitioner, AWS Certified AI Practitioner, AWS Certified Developer – Associate, AWS Certified CloudOps Engineer – Associate, AWS Certified Data Engineer – Associate and more — and works with any other certification exam you describe. You can also upload your own PDF study notes and Prepa will build questions from them.

Is Prepa free to use?

Yes. The free plan lets you generate practice questions, a mock exam, and lessons to try everything out. Pro ($12/month, or $79/year) unlocks daily practice, mock exams, hands-on labs, and the AI tutor and coach. Exam Pass ($39 one-time) gives you everything at exam-cram volume — 250 questions and 2 full mock exams every day — for 90 days. Teams get per-seat pricing at $15/seat/month.

How is Prepa different from static question banks?

Question banks recycle a fixed set of questions and ask you to trust the answer key. Prepa checks its own work — every multiple-choice key is blind-verified by a second, independent model, and every explanation cites the vendor's own documentation. On top of that you get lessons that teach the syllabus, questions tuned to your weak areas, hands-on labs in the real cloud console, spaced-repetition flashcards, and a readiness score that tells you when you're prepared.

What are hands-on labs? Do I need a cloud account?

Labs are guided, step-by-step exercises you run in your own free-tier AWS, Azure, or Google Cloud account — build a real VPC, deploy a real pipeline. Each lab names only free-tier-eligible resources, ends with checkpoint questions that prove you did the work, and includes a cleanup checklist so nothing keeps running and nothing gets billed.

Can I study for more than one exam at once?

Yes. Add as many certifications as you like — each gets its own syllabus, lessons, practice history, readiness score, and study plan. Prepa follows whichever exam you practised last, and you can switch views anytime.

Can I use my own study material?

Yes — upload your PDF notes or course material and Prepa generates practice questions directly from it, alongside its own exam-style questions.

Can I use Prepa with a team, class, or bootcamp cohort?

Yes — the Team plan is $15 per seat per month. Every member gets full Pro access, and team leads can assign the same mock exam to everyone and compare results, track cohort readiness on a team dashboard with a weekly leaderboard and at-risk flags, export progress as CSV, and get a weekly email digest. One subscription, one invoice, add or remove seats anytime.

Does it work on my phone?

Prepa is built mobile-first. Install it to your home screen like a native app and keep practising even when your connection drops.

Walk in knowing you'll pass.

Set up takes under a minute. You get 30 practice questions, two lessons, a hands-on lab and a mock exam free — enough to know whether Prepa suits the way you study.
