AWS Solutions Architect Flashcards: Sorting Exam Material from AWS Trivia (140 Cards)
Study the AWS Solutions Architect deck the smart way: tag 140 cards by SAA-C03 domain, separate exam material from AWS history and add the missing cards.
Most AWS Cloud Practitioner study material drills the same product definitions. The AWS Cloud Practitioner deck on Flip It (deck code BP7875, 191 cards) takes a broader angle: it combines the core cloud concepts you need for the CLF-C02 exam (pay-as-you-go billing, autoscaling, the shared responsibility model, regions and Availability Zones) with the history, numbers and incidents that explain why AWS is built the way it is. It suits anyone who wants to understand AWS, not just pass a multiple-choice test.

What you will memorise
- Core concepts: metered pay-as-you-go billing, autoscaling, on-demand compute, the difference between physical security (Amazon's job) and account management, vulnerability scanning and patching (your job).
- Foundational services: EC2 (virtual computers via REST APIs, CLI or console), S3, Lambda (serverless functions triggered by hundreds of events), SQS (the first public infrastructure service, November 2004), EBS vs EC2 Instance Store, Amazon Bedrock and Amazon Nova.
- Global infrastructure: 38 regions and 120 Availability Zones (October 2025), nine regions in North America, nine in Europe, four in the Middle East, thirteen in Asia-Pacific, over 700 edge points of presence, opt-in regions introduced after March 20, 2019.
- History: web services launch in July 2002, cloud launch in March 2006, S3 on March 14, 2006, EC2 in August 2006, first re:Invent on November 27, 2012, certification programme from April 30, 2013, Andy Jassy, Werner Vogels and the two-pizza teams.
- Business figures: 31% cloud market share (2023 Q1) vs Azure 25% and Google Cloud 11%; revenue of $17.46 billion in 2017, $46 billion in 2020 and $128.7 billion in 2025.
- Outages and security incidents: April 20, 2011 (EBS), October 22, 2012 (memory leak), February 28, 2017 (S3, human error), November 25, 2020 (Kinesis, US-East-1), October 20, 2025, plus the 2019 Capital One breach.
- Programmes and sustainability: AWS Activate, APN, re/Start, Impact Accelerator, the Climate Neutral Data Centre Pact and the 100% renewable energy goal.
Sample cards
| Front | Back |
|---|---|
| What billing model does AWS use? | Metered, pay-as-you-go basis |
| What security aspects are the subscriber's responsibility? | Account management, vulnerability scanning, patching |
| What are Availability Zones? | One or more discrete data centers with redundant power, networking and connectivity |
| Do Availability Zones automatically provide redundancy within a region? | No, they are intentionally isolated to prevent outages from spreading |
| What was AWS's first infrastructure service for public usage? | Simple Queue Service (SQS) |
| What is AWS Lambda? | A serverless function that can run arbitrary code in any language |
| What are the two block-storage options AWS offers? | EC2 Instance Store and Elastic Block Store (EBS) |
| Are IAM resources propagated to disabled opt-in regions? | No, only to enabled regions |
| What caused the February 28, 2017 S3 outage? | Human error during debugging that removed more server capacity than intended |
| What is Amazon Bedrock? | A fully managed service making foundation models available through a single API |
How to study this deck for the exam
Separate exam-critical cards from context cards. Roughly a third of the deck is directly testable on the Cloud Practitioner exam: billing, shared responsibility, regions/AZs, opt-in regions, IAM propagation, EC2/S3/Lambda/EBS definitions. Learn those to 100% first. The history, revenue and outage cards are what make the concepts stick, but you don't need every quarterly figure by heart, so let spaced repetition schedule them at a slower pace.
Turn the outage cards into architecture lessons. Each incident in the deck maps to a design principle the exam expects you to know: the 2011 EBS failure and the 2020 Kinesis outage both hit a single region (US-East-1), which is the argument for multi-AZ and multi-region design; the 2017 S3 outage was human error, which is the argument for automation and least privilege; Capital One was a misconfigured customer resource, which is the shared responsibility model in practice. Reviewing them this way makes two cards out of one.
At 25 new cards a day the deck takes about eight days. Log in at flip-it.app and search the library for AWS Cloud Practitioner or the code BP7875 to add it to your study queue.
