Prep for AWS exams by Designing Solutions.

Design challenges that make you architect real solutions under real constraints. Then answer Exam Style Questions from official AWS documentation. Built by AWS-certified professionals.

The gap

You can spot the right answer in a list of four. Can you choose it when nobody shows you the options?

Design challenges give you a realistic engagement brief with hard constraints and make you decide. Choose a service, configure it, justify it in a line. No four options with one right answer.

That distance between recognising the right architecture and actually choosing it is what the real exam tests.

A design challenge builds a real diagram from your decisions, then runs the month-end spike through it. Here the queue soaks up the burst so the datastore holds. Choose the wrong topology and you watch it break.

How scoring works

55% is deterministic code. 45% grades your reasoning.

40%Deterministic
Constraint satisfaction

Your design is checked against the brief’s hard constraints in code. Same input, same score, every time.

15%Deterministic
Failure simulation

We run the month-end traffic spike through your architecture and see what breaks. Pure simulation, nothing to grade.

45%Model-graded
Reasoning quality

A graded pass per decision against a fixed rubric, quoting your own justification. It checks whether you engaged the constraint and explained the mechanism, not whether it likes your taste.

Timed, exam-format questions written from official AWS documentation. Domain-weighted and scored the way the real exam is.

Instant explanations

Every question comes with a full breakdown: the concept, the service, why the right answer is right and each wrong one is wrong. Straight from the docs.

Progress tracking

Track your readiness across every domain, and see where you recognise the right answer but aren’t yet choosing it.
