Master AWS Certifications with Confidence

Which AWS tool enables developers to embed AWS service functionalities natively within their application codebase?

A company is developing a web application hosted on AWS and wants users to authenticate using social media platforms such as Google and Facebook. The solution must integrate seamlessly with these identity providers (IdPs) without managing user credentials. Which AWS service should be used to fulfill this requirement?

A company is hosting a web application on multiple Amazon EC2 instances spread across several Availability Zones within a single VPC. The application requires a scalable, low-latency storage solution that is simultaneously accessible by all instances, with strict data residency requirements to ensure all data remains within the VPC. What should a solutions architect propose?

A company operates a three-tier application on AWS. The data tier utilizes Amazon RDS for PostgreSQL configured with a Multi-AZ deployment and 8 TB of Provisioned IOPS SSD storage. The application stores images as binary large objects (BLOBs) with an average size of 5 MB. Over time, the database has experienced performance degradation and increased storage costs. The company requires a highly available and resilient solution to enhance performance and reduce expenses.

Which solution MOST cost-effectively meets these requirements?

A company is running a project that launches Amazon EC2 instances larger than necessary. The project's account cannot join the company's AWS Organizations due to compliance requirements mandating operational independence. Developers in the project's account must only launch t3.medium EC2 instances restricted to the us-west-1 Region. What should a solutions architect do to fulfill these requirements?

A large enterprise is planning to migrate its hybrid IT environment, which includes on-premises physical servers running Red Hat Enterprise Linux and Windows Server, along with containerized applications using Docker and Kubernetes, and databases including PostgreSQL and Microsoft SQL Server. The environment has complex interdependencies with legacy systems hosted in a colocation facility and third-party SaaS applications. The existing documentation is outdated and lacks details on current resource utilization. The solutions architect must assess the existing infrastructure, identify dependencies, and provide a detailed cost estimate for the AWS migration.

Which combination of AWS services or tools should the solutions architect use to meet these requirements? (Choose three.)

A company uses AWS CloudFormation to deploy an application with an Amazon API Gateway REST API integrated with AWS Lambda. Data is stored in Amazon DynamoDB, with separate tables for development, testing, and production stages. The company faces challenges when deploying updates to production, despite success in earlier stages. For the next release, the developer must direct 10% of production traffic to the new version while keeping 90% on the current version, ensuring minimal customer errors.

Which approach meets these requirements?

A developer is designing an AWS CloudFormation template for a serverless application that includes Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. Which AWS service or tool allows the developer to define these serverless resources using a simplified YAML syntax?
