Which of the below is an example of an architectural benefit of moving to the cloud?
1. Elasticity
2. Monolithic services
3. Proprietary hardware
4. Vertical scalability

A user is planning to launch three EC2 instances behind a single Elastic Load Balancer. The deployment should be highly available.
1. Launch the instances across multiple Availability Zones in a single AWS Region
2. Launch the instances as EC2 Spot Instances in the same AWS Region and the same Availability Zone
3. Launch the instances in multiple AWS Regions, and use Elastic IP addresses
4. Launch the instances as EC2 Reserved Instances in the same AWS Region, but in different Availability Zones
1. Launch the instances across multiple Availability Zones in a single AWS Region
Explanation: To make the deployment highly available the user should launch the instances across multiple Availability Zones in a single AWS Region. Elastic Load Balancers can only serve targets in a single Region so it is not possible to deploy across Regions.
