Correct answer - "Increase the minimum instances in the ASG to 2" : To maintain the same number
of instances, Amazon EC2 Auto Scaling performs a periodic health check on running instances
within an Auto Scaling group. When it finds that an instance is unhealthy, it terminates that
instance and launches a new one.
"Change the target auto scaling policy for network bytes" - Changing the metric to network byte
will not get you where you need to be because we are dealing with CPU load and not network bytes
"Configure ASG fast failover" - No such option exist
"Enable RDS Multi AZ" - This one of the things you can do if you have a database. In addition to
this you will also need to have more than 1 instance in separate availability zones to make it
highly available
