The application architecture has an Application Load Balancer, an Amazon EC2 web server that hosts user session states, and a MySQL database that runs on an EC2 instance. The company expects sudden increases in application traffic. The company wants to be able to scale to meet future application capacity demands and to ensure high availability across all three Availability Zones.
Which solution will meet these requirements?
A. Migrate the MySQL database to Amazon RDS for MySQL with a Multi-AZ DB cluster deployment. Use Amazon ElastiCache for Redis with high availability to store session data and to cache reads. Migrate the web server to an Auto Scaling group that is in three Availability Zones. B. Migrate the MySQL database to Amazon RDS for MySQL with a Multi-AZ DB cluster deployment. Use Amazon ElastiCache for Memcached with high availability to store session data and to cache reads. Migrate the web server to an Auto Scaling group that is in three Availability Zones. C. Migrate the MySQL database to Amazon DynamoDB Use DynamoDB Accelerator (DAX) to cache reads. Store the session data in DynamoDB. Migrate the web server to an Auto Scaling group that is in three Availability Zones. D. Migrate the MySQL database to Amazon RDS for MySQL in a single Availability Zone. Use Amazon ElastiCache for Redis with high availability to store session data and to cache reads. Migrate the web server to an Auto Scaling group that is in three Availability Zones.

The company needs to ensure that viewers who are outside the countries to which the company rolls out content are not able to view the content.
Which solution will meet these requirements?
A. Add geographic restrictions to the content in CloudFront by using an allow list. Set up a custom error message. B. Set up a new URL tor restricted content. Authorize access by using a signed URL and cookies. Set up a custom error message. C. Encrypt the data for the content that the company distributes. Set up a custom error message. D.

A company wants to use the AWS Cloud to improve its on-premises disaster recovery (DR) configuration. The company’s core production business application uses Microsoft SQL Server Standard, which runs on a virtual machine (VM). The application has a recovery point objective (RPO) of 30 seconds or fewer and a recovery time objective (RTO) of 60 minutes. The DR solution needs to minimize costs wherever possible.
Which solution will meet these requirements?
A. Configure a multi-site active/active setup between the on-premises server and AWS by using Microsoft SQL Server Enterprise with Always On availability groups. B. Configure a warm standby Amazon RDS for SQL Server database on AWS. Configure AWS Database Migration Service (AWS DMS) to use change data capture (CDC). C. Use AWS Elastic Disaster Recovery configured to replicate disk changes to AWS as a pilot light. D. Use third-party backup software to capture backups every night. Store a secondary set of backups in Amazon S3.
