1. A company runs an internal browser-based application. The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales up to 20 instances during work hours, but scales down to 2 instances overnight. Staff are complaining that the application is very slow when the day begins, although it runs well by mid-morning.How should the scaling be changed to address the staff complaints and keep costs to a minimum?

A) Implement a step scaling action triggered at a lower CPU threshold and decrease the cooldown period.
B) Implement a scheduled action that sets the desired capacity to 20 shortly before the office opens.
C) Implement a scheduled action that sets the minimum and maximum capacity to 20 shortly before the office opens.
D) Implement a target tracking action triggered at a lower CPU threshold and decrease the cooldown period



2. A company has recently updated its internal security standards. The company must now ensure all Amazon S3 buckets and Amazon Elastic Block Store (Amazon EBS) volumes are encrypted with keys created and periodically rotated by internal security specialists. The company is looking for a native, software-based AWS service to accomplish this goal.What should a solutions architect recommend as a solution?

A) Use AWS Systems Manager Parameter Store with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in the Parameter Store.
B) Use an AWS CloudHSM cluster with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in the CloudHSM cluster modes.
C) Use AWS Secrets Manager with customer master keys (CMKs) to store master key material and apply a routine to create a new CMK periodically and replace it in AWS Secrets Manager
D) Use AWS Key Management Service (AWS KMS) with customer master keys (CMKs) to store master key material and apply a routine to re-create a new key periodically and replace it in AWS KMS.



3. A company has a web application with sporadic usage patterns. There is heavy usage at the beginning of each month, moderate usage at the start of each week, and unpredictable usage during the week. The application consists of a web server and a MySQL database server running inside the data center. The company would like to move the application to the AWS Cloud, and needs to select a cost-effective database platform that will not require database modification.Which solution will meet these requirements?

A) MySQL-compatible Amazon Aurora Serverless
B) Amazon DynamoDB
C) Amazon RDS for MySQL
D) MySQL deployed on Amazon EC2 in an Auto Scaling group



4. A company has been storing analytics data in an Amazon RDS instance for the past few years. The company asked a solutions architect to find a solution that allows users to access this data using an API. The expectation is that the application will experience periods of inactivity but could receive bursts off traffic within seconds.Which solution should the solutions architect suggest?

A) Set up an Amazon API Gateway and use AWS Lambda functions
B) Set up an Amazon API Gateway and use Amazon EC2 with auto Scaling
C) Set up an Amazon API Gateway and use Amazon ECS
D) Set up an Amazon API Gateway and use AWS Elastic Beanstalk



5. A company's dynamic website is hosted using on-premises servers in the United States. The company is launching its product in Europe, and it wants to optimize site loading times for new European users. The site's backend must remain in the United States. The product is being launched in a few days, and an immediate solution is needed.What should the solutions architect recommend?

A) Move the website to Amazon S3. Use cross-Region replication between Regions.
B) Use Amazon CloudFront with a custom origin pointing to the on-premises servers
C) Launch an Amazon EC2 instance in us-east-1 and migrate the site to it
D) Use an Amazon Route 53 geo-proximity routing policy pointing to on-premises servers.
