Which of the following architectural choices should you make?
You have a web application running on six Amazon EC2 instances, consuming about 45% of resources on each
instance. You are using auto-scaling to make sure that six instances are running at all times. The number of
requests this application processes is consistent and does not experience spikes. The application is critical to
your business and you want high availability at all times. You want the load to be distributed evenly between
all instances. You also want to use the same Amazon Machine Image (AMI) for all instances. Which of the
following architectural choices should you make?

What is the minimum number of subnets that need to be configured in the VPC?
A company wants to implement their website in a virtual private cloud (VPC). The web tier will use an Auto
Scaling group across multiple Availability Zones (AZs). The database will use Multi-AZ RDS MySQL and should

Why is the Internet unreachable from this instance?
You have launched an Amazon Elastic Compute Cloud (EC2) instance into a public subnet with a primary
private IP address assigned, an internet gateway is attached to the VPC, and the public route table is
configured to send all Internet-based traffic to the Internet gateway. The instance security group is set to allow
all outbound traffic but cannot access the internet. Why is the Internet unreachable from this instance?
