AWS Solutions Architect Associate is a AWS certification with approximately 65 questions in 130 minutes. The table below shows the exam weighting published for each domain, so you can decide where to spend your study time instead of working through the syllabus in order.
| Domain | Exam weight | What it covers |
|---|---|---|
| Design Secure Architectures | 30% | Design secure access to AWS resources |
| Design Resilient Architectures | 26% | Design highly available and fault-tolerant architectures |
| Design High-Performing Architectures | 24% | Determine high-performing solutions |
| Design Cost-Optimized Architectures | 20% | Design cost-optimized architectures |
A passing study plan usually trails the weighting: spend the most sessions on Design Secure Architectures (30%), then check the next domain down before moving on. If your accuracy on a high-weight domain stays under 80%, more practice there is worth more than another pass at a low-weight topic.
These questions come from the AWS Solutions Architect Associate practice bank. Read the rationale even when you answer correctly — the explanation is usually where the exam technique lives.
A sports streaming service serves highlight clips from an Amazon S3 bucket in one Region to viewers across four continents. Viewers far from the bucket report slow first-byte times, and the same popular clips are fetched from the origin again and again. The team wants faster delivery of those clips without changing the storage layout. Which service should the team place in front of the bucket?
Answer: A. Option A is correct because CloudFront stores popular objects at edge locations near viewers and serves repeat requests from cache, which lowers first-byte time and reduces how often the origin is contacted. Global Accelerator in Option B optimizes the network path to an endpoint but does not cache the clips. Transfer Acceleration in Option C speeds uploads into the bucket rather than downloads to viewers. The latency records in Option D redirect clients to different Regions, and each request still reaches an origin without caching.
An advertising analytics firm stores 900 TB of clickstream data in Amazon S3. About 10 percent of the objects are read daily, 30 percent are read about once a month, and the rest are accessed less than once a year with patterns that keep changing. The team wants automatic cost reduction without building a retrieval process. Which storage approach should the team adopt?
Answer: B. Option B is correct because S3 Intelligent-Tiering moves objects between access tiers as their usage changes and charges no retrieval fees, which fits data with unknown and shifting access patterns. The lifecycle rule in Option A archives frequently read objects and adds retrieval cost plus delay. Standard-IA in Option C charges per-object retrieval and early deletion fees for data that is read daily. One Zone-IA in Option D lowers durability, and replication adds cost that cancels the saving.
A seismic processing company runs a relational analysis workload on a single Amazon EC2 instance that reads and writes a self-managed database on an Amazon EBS volume. The workload needs roughly 40,000 provisioned IOPS with consistent sub-millisecond latency, and predictable throughput matters more than storage price. Which volume configuration should the team choose?
Answer: C. Option C is correct because an io2 Block Express volume can be sized to satisfy extreme IOPS demands with sub-millisecond latency, which suits a self-managed database that needs consistent performance. The gp3 ceiling in Option A sits below the stated demand, so the job would throttle during heavy scans. A throughput-optimized HDD in Option B targets sequential access and cannot sustain that random IOPS figure. Option D adds I/O capacity by striping gp2 volumes on the instance, but gp2 performance depends on volume size and the combined latency stays variable.

The SAA-C03 exam is organised into 4 domains: Design Secure Architectures (30%), Design Resilient Architectures (26%), Design High-Performing Architectures (24%), Design Cost-Optimized Architectures (20%). The weighting above shows how much of the exam each domain represents, so budget study time in the same proportion.
The SAA-C03 exam has approximately 65 questions in 130 minutes, with a passing score of 720. Practice sets here are scored the same way as the real exam so you can see whether you are above or below the line before test day.
Start with Design Secure Architectures, the highest-weighted domain, then work down the list. Answer a mixed set after each domain pass — mixing domains forces you to identify what a question is asking before recalling the content, which is what the real exam does.
No. These are original practice questions written against the published SAA-C03 exam objectives. They mirror the style, difficulty, and domain weighting of the real exam, but the actual exam content is confidential and is not reproduced here.
