This free SAA-C03 practice test mirrors the structure and difficulty of the real SAA-C03 exam. Every question is written against the official 2026 exam blueprint published by Amazon Web Services, ensuring you practise exactly what the exam tests — not last year's objectives.
The SAA-C03 blueprint is divided into 4weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Design Secure Architectures and Design Resilient Architectures contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.

67 numbered sets, 4 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass SAA-C03 on their first attempt:
Answer before revealing
Read each SAA-C03 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which SAA-C03 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real SAA-C03 gives you roughly 2 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass SAA-C03 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 1,040+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.

A security team requires that every object uploaded to s3://secure-bucket/uploads/ must be encrypted using SSE-KMS with a specific customer-managed KMS key. Which S3 bucket policy condition approach best enforces this requirement for PutObject requests?
Select an answer to reveal the explanation
An application in Account B (IAM role arn:aws:iam::account-b:role/app-read) reads objects from an S3 bucket in Account A. The bucket uses SSE-KMS with a customer-managed KMS key in Account A. Object reads consistently fail with an error that includes "AccessDenied" and "kms:Decrypt".
The IAM permissions in Account B for kms:Decrypt are correct, but the requests still fail.
Which change will most directly fix the failure?
Select an answer to reveal the explanation
A server assumes an IAM role and must read export objects only from this prefix in an S3 bucket: s3://customer-data/exports/acme/ . The application also needs to list the objects under that exact prefix so it can discover which export folders exist. The application performs ListBucket requests with Prefix set to exactly "exports/acme/".
The current role policy allows s3:ListBucket on the bucket ARN without a prefix condition, and security reports the role can list other tenants’ export object keys.
Which IAM policy change best enforces least privilege for both ListBucket and GetObject?

A company serves private images stored in S3 through Amazon CloudFront. Only authenticated users should be able to access each image, and access should expire after 1 hour. Which CloudFront feature best meets this requirement?
Select an answer to reveal the explanation
A backend service uses an IAM role to read files from an S3 bucket. It must only read objects under s3://prod-reporting/incoming/ but currently receives AccessDenied (403) on GetObject for that prefix.
The role already has this statement: - Action: s3:ListBucket - Resource: arn:aws:s3:::prod-reporting
Which policy statement would most directly follow least privilege to allow only the required reads under the incoming prefix?
Select an answer to reveal the explanation
An order-processing service consumes messages from an Amazon SQS Standard queue using a custom worker. During traffic spikes, the worker occasionally times out after performing some work but before acknowledging the message, so SQS redelivers it and it may be processed again.
You also observe that a small set of “poison” messages always fail validation.
What change most directly improves resilience by (1) preventing poison messages from retrying indefinitely and (2) avoiding duplicate side effects caused by legitimate retries?

Based on the exhibit, the application sees several minutes of connection errors during an Aurora failover. What is the best change to reduce failover impact?
Select an answer to reveal the explanation
A payments service receives payment orders by consuming messages from an Amazon SQS Standard queue. The downstream processor occasionally exceeds its processing timeout. As a result, some messages reappear in the queue and may be processed more than once.
The team wants to prevent duplicate side effects (for example, double-charging) and also ensure poison messages do not repeatedly consume processing capacity.
What approach best satisfies both goals?

A company runs an application behind an Application Load Balancer (ALB). An Auto Scaling group (ASG) is configured with desired capacity 2, but it is attached only to subnets in a single Availability Zone. The ALB is healthy because it is configured across multiple Availability Zones.
When the Availability Zone that contains the ASG subnets experiences an outage, what change most directly improves resilience and allows capacity to be restored automatically?

Based on the exhibit, DNS still sends traffic to the primary Region even though Route 53 health checks show the primary endpoint is unhealthy. What is the best change to make failover work as intended?

A production application writes to an Amazon Aurora PostgreSQL cluster. Users report that during business-hour reporting runs, write latency increases. The application team wants to keep the writer focused on OLTP writes while still providing low-latency reads for reporting queries. What architectural approach should the solutions architect recommend?

A DynamoDB table stores device status items. The partition key is deviceId, and the partition distribution is healthy (no single partition dominates). However, during peak periods the application experiences high read latency because many clients repeatedly request the latest status for the same devices. Which action best improves read latency without changing the DynamoDB partitioning model?

An API team runs an AWS Lambda function behind an Application Load Balancer (ALB). During predictable hourly traffic spikes, p95 response latency increases due to occasional cold starts. The team wants stable latency during those spikes without permanently overprovisioning resources for all functions. Which configuration is the most appropriate way to reduce cold starts for this Lambda function?
Select an answer to reveal the explanation
A Lambda function behind an API needs consistent low latency. Traffic normally drops to near zero, then spikes several times per hour. During spikes, the p95 latency often spikes above 800 ms due to cold starts. The team wants to keep using Lambda (no containers) but minimize cold start impact during predictable spikes. What is the best AWS configuration to meet this goal?

A structured study plan dramatically increases your chances of passing SAA-C03 on the first attempt. The most effective approach combines reading the official Amazon Web Services documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for SAA-C03 preparation:
Cover each SAA-C03 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing SAA-C03 score.
On exam day, the SAA-C03 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The SAA-C03 exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 720/1000 does not mean you need 72% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 720/1000 on the real exam.

Every question is written against the official SAA-C03 exam blueprint published by Amazon Web Services. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass SAA-C03 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The SAA-C03 covers 4 domains: Design Secure Architectures (30%), Design Resilient Architectures (26%), Design High-Performing Architectures (24%), Design Cost-Optimized Architectures (20%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Design Secure Architectures and Design Resilient Architectures — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Amazon Web Services's authorisation. Using them violates your NDA and Amazon Web Services's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
