You need your DynamoDB-backed API to remain operational amid a catastrophic regional AWS failure. During a significant failure event, you can accept a few minutes of lag or slowness, but the system should resume regular functioning after those few minutes.
What is an effective strategy?

Correct! Wrong!

There is no such thing as a cross-region ELB, or a cross-region Auto Scaling Group, or a DynamoDB Multi-Region Table. The only viable solution is the cross-regional replication version with two ELBs and ASGs, as well as Route53 Failover and Latency DNS.

A table in an Amazon RDS MySQL DB instance must be dropped and repopulated at each deployment for an n-tier application. This procedure can take several minutes, and the web tier cannot be accessed until it is completed. The web layer is currently set up as an Amazon EC2 Auto Scaling group, with instances terminated and replaced at each deployment. An AWS CodeBuild task does a SQL query to populate the MySQL table.
What steps should be taken to make sure that the web tier does not go online before the database is fully configured?

Correct! Wrong!

Amazon EC2 Auto Scaling lets you add lifecycle hooks to your Auto Scaling groups. These hooks enable you to design solutions that are aware of Auto Scaling instance lifecycle events and then conduct a custom action on instances when the correct lifecycle event happens. A lifecycle hook allows the instance to wait for a given period of time (one hour by default) for the action to finish before moving on to the next stage.
