AWS Solutions Architect - Professional (SAP-C02) — Practice Questions and Mock Exam

The AWS Certified Solutions Architect – Professional is AWS's most demanding architecture credential, validating advanced technical skills in designing complex, multi-tier applications on AWS. It covers organizational complexity, hybrid architectures, migration strategies, cost control mechanisms, and continuous improvement of existing solutions at enterprise scale.

This certification targets experienced solutions architects with two or more years of hands-on AWS experience. It demonstrates the ability to evaluate complex requirements and design architectures that address security, reliability, performance, and cost optimization across multiple AWS accounts and regions.

Design for New Solutions carries the most weight at 29%, covering deployment strategy, business continuity, security controls, reliability, performance, and cost optimization for architectures being built from scratch. Design Solutions for Organizational Complexity follows at 26%, testing network connectivity across a sprawling account structure, multi-account governance, and the security controls that have to hold consistently across all of it.

Continuous Improvement for Existing Solutions takes 25%, nearly matching the two design domains combined, and shifts the question from how to build something new to how to evaluate and fix what's already running — operational excellence, security posture, performance, reliability, and cost, all assessed against an existing workload. Accelerate Workload Migration and Modernization closes the blueprint at 20%, covering the 7 Rs of migration strategy and identifying which workloads are ready for a serverless or specialized database rebuild once they land.

The exam draws 75 questions (65 scored, 10 unscored) from multiple-choice and multiple-response formats inside a 180-minute window. Questions are long and dense, often laying out several pages of business requirements before asking for the single best architectural approach among multiple valid options. At 2.4 minutes per question, strict time discipline matters — reading for the specific constraints buried in a scenario is the skill being tested.

Every domain of the SAP-C02 exam has enough questions in the pool to practice it in depth. A mock exam asks 75 questions in one sitting, on the same 180-minute clock as the real thing.

How long you'll need depends on how much hands-on experience you bring. The rest is set by the vendor: how the exam is delivered, how soon you can retake it, and how long the credential stays valid.

The exam runs through Pearson VUE, either at a testing center or online with a remote proctor, and is offered in English, Japanese, Korean, Portuguese (Brazil), Spanish (Latin America), and Simplified Chinese. Certification holds for 3 years; passing a recertification exam renews it, and because this is a professional-level credential, earning it also renews any associate-level AWS certification you hold.

The lengthy, multi-page scenarios consume significant reading time, and candidates who haven't practiced pacing often run out of time before finishing. Multi-account design (AWS Organizations, service control policies, cross-account IAM roles, and Control Tower) comes up repeatedly in the organizational-complexity domain, and hybrid networking questions expect a working grasp of how Direct Connect, Transit Gateway, VPN, and PrivateLink fit together rather than definitions of each in isolation. Migration questions test judgment across the full set of migration strategies rather than memorization of a fixed list, and on questions where several answers are technically valid, the exam wants the best one given every stated constraint — being technically correct isn't enough.
