Introduction


The AWS Certified Solutions Architect – Associate 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 using architecture best practices.
  • Provide guidance on architectural best practices to developers and system administrators throughout the lifecycle of the project.
  • The knowledge and skills required at this level should include all of the following areas and objective components.

AWS Knowledge


• Hands-on experience using compute, networking, storage, and database AWS services
• Professional experience architecting large-scale distributed systems
• Understanding of elasticity and scalability concepts
• Understanding of the AWS global infrastructure
• Understanding of network technologies as they relate to AWS
• A good understanding of all security features and tools that AWS provides and how they relate to traditional services
• A strong understanding of client interfaces to the AWS platform
• Hands-on experience with AWS deployment and management services

General IT Knowledge
• Excellent understanding of typical multi-tier architectures: web servers, caching, application servers, load balancers, and storage
• Understanding of Relational Database Management System (RDBMS) and NoSQL
• Knowledge of message queuing and Enterprise Service Bus (ESB)
• Familiarity with loose coupling and stateless systems
• Understanding of different consistency models in distributed systems
• Knowledge of Content Delivery Networks (CDN)
• Hands-on experience with core LAN/WAN network technologies
• Experience with route tables, access control lists, firewalls, NAT, HTTP, DNS, IP and OSI Network
• Knowledge of RESTful Web Services, XML, JSON
• Familiarity with the software development lifecycle
• Work experience with information and application security concepts, mechanisms, and tools
• Awareness of end-user computing and collaborative technologies


These training courses or other equivalent methodologies will assist in exam preparation:

• Architecting on AWS (aws.amazon.com/training/architect)
• In-depth knowledge or training in at least one high-level programming language
• AWS Cloud Computing Whitepapers (aws.amazon.com/whitepapers)
   o Overview of Amazon Web Services
   o Overview of Security Processes
   o AWS Risk & Compliance Whitepaper
   o Storage Options in the Cloud
   o Architecting for the AWS Cloud: Best Practices
• Experience deploying hybrid systems with on-premises and AWS components
• Use of the AWS Architecture Center website (aws.amazon.com/architecture)

Response Limits
The examinee selects—from four or more response options—the one or multiple options that best complete the statement or answer the question. Distracters, or wrong answers, are response options that examinees with incomplete knowledge or skill would probably choose, and are generally plausible responses that fit 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: Examinee reads the statement or question and, from the response options, selects only the options that represent the most correct or best answers given the information.
