A solutions architect has developed a web application that uses an Amazon API Gateway Regional endpoint and an AWS Lambda function. The consumers of the web application are all close to the AWS Region where the application will be deployed. The Lambda function only queries an Amazon Aurora MySQL database. The solutions architect has configured the database to have three read replicas.
During testing, the application does not meet performance requirements. Under high load, the application opens a large number of database connections. The solutions architect must improve the application's performance.
Which actions should the solutions architect take to meet these requirements? (Choose two.)
A company developed a pilot application by using AWS Elastic Beanstalk and Java. To save costs during development, the company's development team deployed the application into a single-instance environment. Recent tests indicate that the application consumes more CPU than expected. CPU utilization is regularly greater than 85%, which causes some performance bottlenecks.
A solutions architect must mitigate the performance issues before the company launches the application to production.
Which solution will meet these requirements with the LEAST operational overhead?
A company is launching a new online game on Amazon EC2 instances. The game must be available globally. The company plans to run the game in three AWS Regions: us-east-1, eu-west-1, and ap-southeast-1. The game's leaderboards. player inventory, and event status must be available across Regions.
A solutions architect must design a solution that will give any Region the ability to scale to handle the load of all Regions. Additionally, users must automatically connect to the Region that provides the least latency.
Which solution will meet these requirements with the LEAST operational overhead?
A company maintains information on premises in approximately 1 million .csv files that are hosted on a VM. The data initially is 10 TB in size and grows at a rate of 1 TB each week. The company needs to automate backups of the data to the AWS Cloud.
Backups of the data must occur daily. The company needs a solution that applies custom filters to back up only a subset of the data that is located in designated source directories. The company has set up an AWS Direct Connect connection.
Which solution will meet the backup requirements with the LEAST operational overhead?
A company needs to improve the security of its web-based application on AWS. The application uses Amazon CloudFront with two custom origins. The first custom origin routes requests to an Amazon API Gateway HTTP API. The second custom origin routes traffic to an Application Load Balancer (ALB) The application integrates with an OpenlD Connect (OIDC) identity provider (IdP) for user management.
A security audit shows that a JSON Web Token (JWT) authorizer provides access to the API The security audit also shows that the ALB accepts requests from unauthenticated users
A solutions architect must design a solution to ensure that all backend services respond to only authenticated users

A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years.
The company's business has grown rapidly in the past few months. In response the company's operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.
The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances.
Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)
A company is deploying a new API to AWS. The API uses Amazon API Gateway with a Regional API endpoint and an AWS Lambda function for hosting. The API retrieves data from an external vendor API, stores data in an Amazon DynamoDB global table, and retrieves data from the DynamoDB global table. The API key for the vendor's API is stored in AWS Secrets Manager and is encrypted with a customer managed key in AWS Key Management Service (AWS KMS). The company has deployed its own API into a single AWS Region.
A solutions architect needs to change the API components of the company's API to ensure that the components can run across multiple Regions in an active-active configuration.
Which combination of changes will meet this requirement with the LEAST operational overhead? (Choose three.)
A company has accounts in an organization in AWS Organizations. The organization has all features enabled. The company stores secrets in AWS Secrets Manager in a central AWS account (Account A). The secrets have resource policies that allow read-only access to 1AM roles in an account outside the organization (Account B). A few privileged users in accounts in the organization have access to the secrets by using 1AM roles.
Because of a security incident, the company needs to revoke all access to the secrets in Account A.
