Prepare for AWS Certified Solutions Architect - Associate by connecting business requirements to design choices across all four exam domains. This SAA-C03 guide explains the tested areas, gives you an original database scenario to reason through, and provides a practical preparation checklist.
Is Solutions Architect Associate right for you?
The AWS Certified Solutions Architect – Associate (SAA-C03) exam validates your ability to design solutions based on the AWS Well-Architected Framework: architectures that are secure, resilient, high-performing, and cost-optimized.
AWS recommends at least one year of hands-on experience designing cloud solutions with AWS services. The exam asks you to design solutions for business requirements and review existing designs for improvements.
Cloud Practitioner and an AWS training course are not prerequisites. AWS suggests Cloud Practitioner for candidates without IT work experience. Deep hands-on coding experience is not required for SAA-C03, although basic programming familiarity can help.

What to expect on the exam
The exam runs 130 minutes with 65 questions in multiple-choice or multiple-response form. Fifty questions affect your score; 15 are unscored pretest items that are not identified on the exam.
Multiple-choice questions have one correct answer and three distractors. Multiple-response questions have two or more correct answers among five or more options. Follow each question’s selection instructions. Unanswered questions count as incorrect, and there is no penalty for guessing.
The passing score is 720 on a scale of 100–1,000. This scaled score cannot be read as a raw requirement to answer 72% correctly. You pass on the overall result, with no separate passing requirement for every domain.
Most AWS exams do not show a pass or fail result immediately on screen. Check your AWS Certification Account for detailed results within five business days.

What to study in each domain
Cover all four domains. Their weights describe scored content; use your own knowledge gaps as well as those weights when allocating study time.
The official guide breaks each domain into tasks and supporting knowledge and skills. Its content and service lists are not exhaustive. Use the table to organize your study, then check the detailed tasks in the current guide. The practice activities are suggestions for learning those topics.
| Domain | Weight | Topics and suggested practice |
|---|---|---|
| Design Secure Architectures | 30% | Secure access, workloads, applications, and data. Review a sample design’s access requirements and identify which security decisions you need to justify. |
| Design Resilient Architectures | 26% | Scalability, loose coupling, high availability, and fault tolerance. Work through a failure scenario and explain which design requirement each option meets. |
| Design High-Performing Architectures | 24% | Storage, compute, databases, networking, and data ingestion and transformation. Compare design options against the performance and scaling needs in a scenario. |
| Design Cost-Optimized Architectures | 20% | Storage, compute, database, and network costs. Identify the usage assumptions you need before comparing the cost of two designs. |

Understand availability and read scaling
An RDS Multi-AZ DB instance deployment uses a synchronous standby in another Availability Zone for high availability. That standby cannot serve read traffic.
This is specifically the deployment with a single standby DB instance. AWS directs you to a read replica or a Multi-AZ DB cluster when you need to serve read-only traffic. Keep those deployment types distinct when reading a scenario.
RDS automatically switches to the standby for the documented failover conditions. Automatic failover still takes time, and existing connections must be re-established. Do not turn an availability feature into a promise of uninterrupted application service.

Practice: choose an RDS availability option
Read the requirement and compare the three options before revealing the answer. The follow-up checks whether the standby can also take reporting traffic.
This is an original study exercise about a Multi-AZ DB instance deployment, not a Multi-AZ DB cluster.
Practice decision
A team has a Single-AZ Amazon RDS for PostgreSQL DB instance. It needs managed, automatic failover to another Availability Zone if the primary becomes unavailable because of an infrastructure failure. Current read capacity is sufficient; there is no cross-Region requirement or engine change. Which option meets the failover requirement? A) Keep Single-AZ and use nightly backups with a manual restore runbook. B) Convert to a Multi-AZ DB instance deployment with a synchronous standby in a different Availability Zone. C) Keep Single-AZ and select a larger primary instance class. Follow-up: can the standby in option B serve reporting queries?
Show answer
B meets the stated failover requirement. Its single standby cannot serve reporting queries.
A Multi-AZ DB instance deployment provides failover support through its standby in another Availability Zone. AWS documents an automatic switch for an infrastructure outage. Option A still depends on a manual restore; option C still leaves the instance in one Availability Zone. Neither supplies the requested standby failover arrangement. The RDS documentation explicitly excludes read traffic on that single standby. A new reporting requirement would need a separate design decision, such as considering a read replica or Multi-AZ DB cluster. Automatic failover is not a guarantee of zero interruption: existing database connections must be re-established.

Practice explaining the design decision
For each practice scenario, write a short explanation that connects the chosen option to the stated requirements.
The exam guide includes architecture concepts such as scaling, loose coupling, event-driven applications, messaging, and disaster recovery. Use those topics to choose practice tasks; consult the relevant service documentation for the behavior you rely on.
- List the requirements before choosing a service: for example, availability, performance, security, and cost.
- Explain why the chosen option meets the stated need and why each alternative does not.
- State what would need to change in the scenario for a different option to become appropriate.
- Record any assumption that the question did not establish, and check it before treating it as a fact.

Your preparation checklist
Use this suggested sequence to turn the syllabus into manageable study tasks.
AWS’s preparation path combines exam-style questions, learning to address gaps, practice, and a readiness assessment. Adapt those steps to your experience; a familiar topic list or one practice score is not a guarantee of readiness.
- Confirm SAA-C03 on your booking and use the corresponding official exam guide.
- Review every domain task and mark where you need explanation, hands-on practice, or further reading.
- Use the official practice question set to learn the question style, then review the reasoning behind your answers.
- Choose labs or design exercises for your weak areas and write down the requirement, result, and trade-off you learned.
- Revisit the RDS example and explain both the failover choice and the standby’s read-traffic limitation.
- Use a practice exam to identify remaining gaps. Check your appointment instructions, testing mode, language, and schedule-change deadline.

Booking and keeping your certification current
The listed exam fee is USD 150, with taxes and local-currency pricing where applicable. The certification is valid for three years.
Book through your AWS Certification Account with Pearson VUE, choosing a test center or online proctoring where available. The standard policy permits cancellation or rescheduling up to 24 hours before the appointment; check the full policy for exceptions.
After a failed attempt, wait 14 calendar days before retaking the exam. AWS states that each attempt requires the full registration fee and that there is no limit on attempts.
The Italian version of SAA-C03 will retire after December 31, 2026. This is a language-specific announcement, not retirement of the whole exam. Check language availability when booking.
To recertify, AWS lists passing the latest version of the Associate exam or earning AWS Certified Solutions Architect - Professional. Check the current recertification rules before your credential expires.
