Question 308
A company recently migrated a message processing system to AWS. The system receives messages into an ActiveMQ queue running on an Amazon EC2 instance. Messages are processed by a consumer application running on Amazon EC2. The consumer application processes the messages and writes results to a MySQL database running on Amazon EC2. The company wants this application to be highly available with low operational complexity. Which architecture offers the HIGHEST availability?
Question 309
A company is planning on deploying a newly built application on AWS in a default VPC. The application will consist of a web layer and database layer. The web server was created in public subnets, and the MySQL database was created in private subnets. All subnets are created with the default network ACL settings, and the default security group in the VPC will be replaced with new custom security groups. The following are the key requirements: - The web servers must be accessible only to users on an SSL connection. - The database should be accessible to the web layer, which is created in a public subnet only. - All traffic to and from the IP range 182.20.0.0/16 subnet should be blocked. Which combination of steps meets these requirements? (Choose two.)
