Your company is building a music sharing platform on which users can
upload their songs. As a solutions architect for the platform, you have
designed an architecture that will leverage a Network Load Balancer linked
to an Auto Scaling Group across multiple availability zones. The songs live on
an FTP that your EC2 instances can easily access. You are currently running
