Simulate real exam conditions
For the most realistic SAA-C03 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (130 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
What this SAA-C03 mock exam covers
This free SAA-C03 mock exam uses the same question distribution as the real SAA-C03 exam. Each session draws questions proportionally from all 4 blueprint domains published by Amazon Web Services, so the topic mix you see accurately reflects what you'll face on test day.

Design Resilient Architectures

Every question is written by certified engineers against the 2026 SAA-C03 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Mock exam vs practice test: what's the difference?
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your SAA-C03 study plan.
Practice test — for learning
Use the SAA-C03 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the SAA-C03 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A Lambda function needs to read the current value of exactly one AWS Secrets Manager secret at startup. Which least-privilege IAM permission (action and resource scope) should you grant to the Lambda execution role?

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?

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?

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 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?

You store application logs in an S3 bucket. After 30 days, the logs are rarely accessed, but you must retain them for 1 year for compliance. Which S3 feature is the best way to reduce storage cost while meeting the retention requirement?

SAA-C03 exam-day strategy
Sitting the SAA-C03 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The SAA-C03 gives you 0.1 minutes per question. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most SAA-C03 distractors contain a subtle error — look for absolute language (always, never, only) as a red flag.
Amazon Web Services writes many SAA-C03 questions as realistic IT scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real SAA-C03 is a mental marathon. In the week before your exam, do at least two full 1000-question sessions on separate days to build concentration stamina. If you cannot focus for 130 minutes in practice, you will struggle on exam day.

Scaled scoring
The SAA-C03 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 720 threshold, giving you a buffer for any unexpected question types on the real exam.
SAA-C03 mock exam — frequently asked questions
Is this SAA-C03 mock exam free?
Yes — all mock exam questions are completely free with no account required. Create a free Courseiva account to save your scores, see per-domain performance, and track your readiness over time. The platform is free forever, supported by advertising.
How does the SAA-C03 mock exam differ from the practice test?
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
What score should I aim for before booking my SAA-C03 exam?
Aim for consistent scores of 80% or above on full-length SAA-C03 mock exams before booking your test date. The official passing score of 720/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for the difficulty variation and question styles on the real exam.
How many times should I do a full SAA-C03 mock exam?
Most candidates who pass SAA-C03 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
Are these SAA-C03 mock questions the same as exam dumps?
No — all Courseiva questions are original, written by certified engineers against public Amazon Web Services exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Amazon Web Services certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
