AWS architecture, understood.SAA-C03

Read the constraint.
See the architecture.

You understand the AWS services. Small distinctions and misread constraints can still cost you points. Practice connecting the words in a scenario to the architectural decisions they require—and explaining why the alternatives fall short.

Your prediction comes first

Try the first step of Model.

Choose an answer and your confidence. Then Model shows the reasoning, step by step.

Global static site with a private S3 origin

Aster Labs publishes a static documentation and marketing site: HTML, CSS, JavaScript, and about 900 product screenshots, held in one S3 bucket in eu-west-1.

Readers open it from three continents, and the two-person platform team wants every asset answered by a cache close to the reader rather than the single Region.

A security review closed with one rule: viewers may reach the site only through the CDN, and no browser request may read an object from the bucket itself.

Which architecture keeps the S3 origin private while serving the site from the edge?
How certain is your prediction?

Inside the learning loop

From explanation to independence

Don’t just recognize the answer.
Understand what makes it work.

The Deconstructor gives you three ways into the same scenario. Start with a model, practice with support, then put your own reasoning to the test.

  1. Model01

    See the reasoning unfold.

    Follow a worked scenario from its key phrases to the requirements they create. See why one architecture fits—and where the alternatives fall short.

    A worked example, with the connections visible.

  2. Coach02

    Build the connections yourself.

    Identify the evidence in the brief and connect it to architectural requirements. Use focused feedback to check the connections you make.

    Your reasoning, with guidance along the way.

  3. Solo03

    Make your own case.

    Work through the scenario independently, then compare your decisions with the expert reasoning. Return to the connections that need another look.

    Independent practice, with something to learn from.

Before you begin

A few useful answers.

How we create and correct content
Who is CertGraph for?

Learners working through AWS architecture and SAA-C03 concepts who want to understand the tradeoffs behind a decision. You can explore the practice content without an AWS account or a CertGraph account.

How does the first workout work?

Start by predicting an answer and recording your confidence. Model then walks through the scenario’s evidence, requirements, and architectural choices. The guidance is authored, prepared content—not a live AI tutor.

Where does my progress go?

Guest progress stays in this browser. It does not automatically sync to another device. Use Local Data in the gym to export a backup; clearing browser data can remove your saved progress.

Are these official AWS exam questions?

No. CertGraph is independent and uses synthetic practice content informed by AWS documentation. It is not affiliated with AWS, does not include real exam items, and does not promise a certification result.

Does CertGraph track me?

Not unless you turn it on. CertGraph loads no third-party analytics or advertising tools. Product analytics is off by default and optional: if you enable it in Data & feedback or Privacy choices, CertGraph sends a few pseudonymous milestone events (like “workout started” or “Model walkthrough completed”) to its own server—never your answers, scores, reasoning, name, or IP address. You can turn it off or delete what was shared at any time.

Your next architectural decision

Start with one scenario.

A global site. A private origin. A reason for every choice.
