A company has an application that sells tickets online and experiences bursts of demand every 7
days. The application has a stateless presentation layer running on Amazon EC2. an Oracle database
to store unstructured data catalog information, and a backend API layer. The front-end layer uses an

Zones (AZs). The Oracle database is running on a single EC2 instance. The company is experiencing
performance issues when running more than two concurrent campaigns. A solutions architect must
design a solution that meets the following requirements:
• Address scalability issues.
• Increase the level of concurrency.
• Eliminate licensing costs.
• Improve reliability.

Question 6/106/10
A solutions architect has an operational workload deployed on Amazon EC2 instances in an Auto
Scaling group. The VPC architecture spans two Availability Zones (AZ) with a subnet in each that the
Auto Scaling group is targeting. The VPC is connected to an on-premises environment and
connectivity cannot be interrupted. The maximum size ol the Auto Scaling group is 20 instances in
service. The VPC IPv4 addressing is as follows:
VPC CIDR: 10.0.0.0/23
AZ1 subnet CIDR: 10.0.0.0/24
AZ2 subnet CIDR: 10.0.1.0/24
Since deployment, a third AZ has become available in the Region. The solutions architect wants to
adopt the new AZ without adding additional IPv4 address space and without service downtime.
