Introduction
The AWS Certified Solutions Architect – Professional Level exam is intended for individuals who perform a Solutions Architect role. This exam validates an examinee’s ability to:

  • Identify and gather requirements in order to define a solution to be built on AWS
  • Evolve systems by introducing new services and features
  • Assess the tradeoffs and implications of architectural decisions and choices for applications deployed in AWS
  • Design an optimal system by meeting project requirements while maximizing characteristics such as scalability, security, reliability, durability, and cost effectiveness
  • Evaluate project requirements and make recommendations for implementation, deployment, and provisioning applications on AWS
  • Provide best practice and architectural guidance over the lifecycle of a project

AWS Knowledge

  • AWS core services, including: Compute and Networking, Storage and CDN, Database, Application Services, Deployment and Management.
  • Security features that AWS provides and best practices
  • Able to design and implement for elasticity and scalability
  • Network technologies as they relate to AWS networking, including: DNS & load balancing, Amazon VPC, and AWS Direct Connect
  • Storage and archival options
  • State management
  • Database and replication methodologies
  • Self-healing techniques and fault-tolerant services
  • Disaster Recovery and fail-over strategies
  • Application migration plans to AWS
  • Network connectivity options
  • Deployment and management

General IT Knowledge


  • Large-scale distributed systems architecture
  • Eventual consistency
  • Relational and non-relational databases
  • Multi-tier architectures: load balancers, caching, web servers, application servers, networking and databases
  • Loose coupling and stateless systems
  • Content Delivery Networks
  • System performance tuning
  • Networking concepts including routing tables, access control lists, firewalls, NAT, HTTP, DNS, TCP/IP, OSI model
  • RESTful Web Services, XML, JSON
  • One or more software development models
  • Information and application security concepts including public key encryption, remote access, access credentials, and certificate-based authentication


These training courses and materials will assist in exam preparation:


Architecting on AWS (aws.amazon.com/training/architect)
Architecting on AWS – Advanced Concepts
In-depth knowledge or training in at least one high-level programming language
AWS Cloud Computing Whitepapers (aws.amazon.com/whitepapers)
    o Overview of Security Processes
    o Storage Options in the Cloud
    o Defining Fault Tolerant Applications in the AWS Cloud
    o Overview of Amazon Web Services
    o Compliance Whitepaper
    o Architecting for the AWS Cloud
Experience deploying hybrid systems with on-premises and AWS components
Utilization of the AWS Architecture Center website (aws.amazon.com/architecture)

Response Limits
The examinee selects from four (4) or more response options the option(s) that best completes the statement or answers the question. Distracters or wrong answers are response options that examinees with incomplete knowledge or skill would likely choose, but are generally plausible responses fitting into the content area defined by the test objective.


Test item formats used in this examination are:


Multiple-choice: examinee selects one option that best answers the question or completes a statement. The option can be embedded in a graphic where the examinee “points and clicks” on their selection choice to complete the test item.
Multiple-response: examinee selects more than one option that best answers the question or completes a statement.
Sample Directions: Read the statement or question and from the response options, select only the option(s) that represent the most correct or best answer(s) given the information.
