question 76

Multiple Choice

A company needs to deploy a web application on two Amazon EC2 instances behind an Application Load Balancer (ALB) . Two EC2 instances will also be deployed to host the database.

How should this be achieved within a VPC?

• A) Use two AZs and create a public subnet in each AZ for the Application Load Balancer, a private subnet in each AZ for the web servers, and a private subnet in each AZ for the database servers.
• B) Use two AZs and create a public subnet in each AZ for the Application Load Balancer, a public subnet in each AZ for the web servers, and a public subnet in each AZ for the database servers.
• C) Use two AZs and create one public subnet for the Application Load Balancer, a private subnet in each AZ for the web servers, and a public subnet in each AZ for the database servers.
• D) Use two AZs and create one public subnet for the Application Load Balancer, a public subnet in each AZ for the web servers, and a private subnet in each AZ for the database servers.
