A company has an on-premise Active Directory (AD) that manages identities for its employees. They have recently begun leveraging AWS for their new cloud-native applications. The security team has specified that the company must maintain a single unified identity management system. They want to ensure that on-premise users can access AWS resources without requiring separate AWS IAM user accounts, and permissions should be managed centrally through AD groups. They will also need to share certain AWS resources within various departments using AWS accounts without replicating resources or compromising security controls. Given these criteria, which solution should the Solutions Architect recommend?
Show answer
CORRECT ANSWERThe Architect should federate the on-premise AD with AWS using AWS Directory Service and IAM roles, and use AWS Resource Access Manager to share resources across the AWS accounts.
Federating an on-premise directory service with AWS IAM roles allows users to assume IAM roles based on their AD credentials, eliminating the need to create IAM users for each employee. AWS Resource Access Manager enables the sharing of AWS resources between accounts in a secure manner, which aligns with the requirement to share resources without replicating them or compromising security.
A company with an international customer base is running a multi-tier web application on AWS, which includes web servers, application servers, and a MySQL database. The application experiences high latency and traffic congestion due to its global user base. The company's goal is to improve the application's performance and reduce the latency for its users worldwide without making changes to the application code or infrastructure. As an AWS Certified Solutions Architect - Associate, which AWS service would you recommend to reduce latency and improve overall performance by routing user traffic through the AWS global network infrastructure?
Show answer
CORRECT ANSWERAWS Global Accelerator
AWS Global Accelerator improves application performance by routing user traffic through AWS's global network infrastructure, reducing latency and improving the user experience. It optimally routes traffic to the nearest application endpoint, even across multiple AWS regions, thus fulfilling the company's requirement without altering the application itself.
A company is developing a new web application that will be deployed on AWS. The application requires a shared file system that can automatically scale as the number of application instances increases due to user demand. The file system must also support a POSIX-compliant file system interface to allow their existing on-premises applications to integrate seamlessly without code modifications. Which AWS storage service should the Solutions Architect recommend?
Show answer
CORRECT ANSWERAmazon Elastic File System (Amazon EFS)
Amazon EFS is a scalable file storage to use with AWS Cloud services and on-premises resources. It is designed to scale on demand to petabytes without disrupting applications, grow and shrink automatically as you add and remove files, and is POSIX-compliant which makes it suitable for the company's requirements.
A company has recently transitioned to AWS, but still maintains a significant amount of on-premises data, generating about 1 TB of new data each month. This data is rarely accessed, but must be preserved for regulatory reasons. The company needs a cost-effective solution that allows them to store their on-premises backup data on AWS, while ensuring that the data is readily accessible when needed for compliance. Which AWS service should they use to meet these requirements?
Show answer
CORRECT ANSWERAWS Storage Gateway in a File Gateway configuration.
AWS Storage Gateway's File Gateway configuration allows the organization to store and access files in S3 as they would on-premises storage, which is cost-effective because it takes advantage of the low cost of S3 storage and lifecycle policies to automatically transfer data to S3 Glacier or S3 Glacier Deep Archive for even more cost savings on infrequently accessed items.

About the SAA-C03 exam
The AWS Certified Solutions Architect - Associate exam's difficulty is significantly influenced by the extensive scope of topics it covers. This wide-ranging content demands a thorough understanding of many AWS services and their integration, which can be daunting, especially for those new to AWS or cloud computing.
The exam covers key areas including compute, storage, databases, networking, security, and application architecture. For compute, you need to understand services like EC2, which involves knowledge of instance types, pricing models, and scaling strategies. You must also be familiar with Lambda, which introduces a serverless paradigm that requires a different approach to architecture and deployment compared to traditional server-based models.
Storage is another critical domain, with services like S3 and EBS. Understanding S3 includes grasping its storage classes, bucket policies, and lifecycle management, while EBS requires knowledge of volume types, performance characteristics, and backup solutions. Databases on AWS span both relational (RDS) and non-relational (DynamoDB) systems, each with its own configuration, scaling, and maintenance considerations.
Networking on AWS involves VPC, subnets, routing tables, and gateways, which are foundational to designing secure and efficient cloud architectures. You must understand how to set up and manage these components to ensure proper isolation, connectivity, and security. Security itself is a vast topic, covering IAM (Identity and Access Management), encryption, and compliance requirements. Mastery of these elements is crucial, as security misconfigurations can lead to vulnerabilities.
The application architecture domain requires knowledge of how to design distributed systems that are highly available, fault-tolerant, and scalable. This involves using load balancers, auto-scaling groups, and designing stateless applications. Moreover, understanding the cost implications of architectural decisions is vital for optimizing performance while managing expenses.
The interrelated nature of these topics adds to the complexity. For instance, designing a fault-tolerant application involves not just compute and storage considerations but also networking and security configurations.
Effective preparation for the exam requires an integrated understanding of how these services work together to build robust, efficient, and secure solutions.
The breadth and depth of knowledge required across these domains, coupled with the need to stay updated with AWS’s frequent service updates and enhancements, contribute significantly to the exam's difficulty.
Technologies and concepts
Compute
Computing involves the use of computers to process data, execute tasks, and run applications. In the context of cloud computing, this translates to leveraging remote servers hosted on the internet to perform these functions rather than relying on local servers or personal computers. AWS supports this with Amazon EC2 for scalable virtual servers, AWS Lambda for serverless computing that executes code in response to events, Amazon ECS and EKS for managing containerized applications, and AWS Fargate for running containers without managing servers.
Cost management
Cost management involves monitoring, controlling, and optimizing spending on cloud resources. AWS supports this with AWS Cost Explorer for visualizing and analyzing cost and usage over time, AWS Budgets for setting and tracking custom cost and usage budgets, AWS Trusted Advisor for providing recommendations to optimize costs, and AWS Cost and Usage Report for detailed billing information.
