AWS Certified Solutions Architect - Professional Practice Test
The AWS Certified Solutions Architect - Professional (SAP-C03) assesses advanced design judgment for AWS solutions aligned with the Well-Architected Framework. Candidates apply architecture experience to complex requirements involving availability, security, performance, and cost. Practice-bank scenarios include selecting data and configuration services, granting workload permissions, automating infrastructure, auditing activity, and routing users across Regions.
Exam overview
About the AWS Certified Solutions Architect - Professional Exam
Professional architecture work requires translating business and technical constraints into designs that remain reliable as workloads, traffic, and failure conditions change. That includes choosing storage and database patterns for access and scaling needs, separating application state from durable data, and designing multi-Availability Zone or multi-Region behavior. Security decisions include assigning least-privilege permissions to workloads, controlling encryption-key use, and retaining activity records for investigation. Candidates also need to compare managed services and operational tradeoffs, automate resource changes with declarative infrastructure, and plan observability for application behavior. The practice bank uses scenarios touching these decisions; use them to explain why a service or pattern fits a stated requirement, and identify the tradeoff that rules out alternatives.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A team wants to store an application's configuration files in a fully managed service that can keep data synchronized and replicated across multiple Availability Zones with high availability. Which service is most appropriate?
Show answer
Correct answer: BAmazon EFS is a managed file system that is highly available and designed for shared access across multiple Availability Zones. FSx for Lustre is specialized for high-performance workloads, Glacier Deep Archive is for archival storage, and EBS Multi-Attach is limited to specific use cases and does not provide a shared file system experience like EFS.
An application running on EC2 needs permission to read from an S3 bucket. Which approach is the most secure and operationally preferred way to provide those permissions?
Show answer
Correct answer: BAttaching an IAM role to the EC2 instance provides temporary credentials automatically and avoids managing long-term secret keys in the application. This is the preferred pattern for AWS access from compute resources.
A web application on Amazon EC2 must store temporary session data with very low latency. The data does not need to survive an instance stop or host failure. Which service is the best fit?
Show answer
Correct answer: CAmazon ElastiCache is designed for in-memory caching and very low-latency access. For nonpersistent session data, it is a better fit than block storage or object storage.
A team needs to deploy and manage AWS infrastructure using declarative templates that can create, update, and roll back related resources together. Which service should they use?
Show answer
Correct answer: AAWS CloudFormation is the infrastructure as code service for defining and provisioning AWS resources as stacks with change management and rollback support.
A company needs encrypted data-at-rest for an application and wants AWS to manage the key lifecycle while keeping fine-grained access control over key usage. Which service should be used?
Show answer
Correct answer: AAWS KMS is the AWS service used to create and manage encryption keys and control their use through IAM policies and key policies. It is the standard choice for encrypting data at rest across many AWS services.
A team needs a managed relational database that can scale read traffic by adding replicas while keeping the primary writer separate. Which AWS service best supports this pattern?
Show answer
Correct answer: AAmazon RDS read replicas are used to scale read-heavy workloads by offloading read traffic from the primary database instance. They are a standard relational scaling option.
A workload needs a fully managed, serverless SQL data warehouse that can query data using standard SQL and scale storage and compute separately. Which AWS service should be used?
Show answer
Correct answer: AAmazon Redshift Serverless is designed for analytics and data warehousing with managed infrastructure and elastic scaling. RDS is for relational OLTP databases, Neptune is a graph database, and DynamoDB is a NoSQL key-value/document store.
How to use this practice test
The free US Practice Tests practice bank contains 50 published questions. Each session presents up to 20 questions selected at random, then shows your results. Use missed or uncertain items to pinpoint decisions to revisit—for example, IAM role design, database scaling, infrastructure deployment, or Route 53 latency routing—and explain the requirement each choice addresses.
Preparation tips
- For each architecture scenario, list its availability, latency, durability, security, and cost constraints before comparing services.
- Practice explaining when EC2 instance profiles and least-privilege IAM policies are preferable to embedded credentials for S3 access.
- Compare relational read replicas, in-memory caching, and durable storage by workload behavior, failure tolerance, and data consistency needs.
- Trace how CloudFormation stack updates and rollbacks affect related resources, dependencies, and operational recovery.
- Distinguish Route 53 latency-based routing from other traffic policies, and connect the choice to client location and regional endpoints.
