No Health Check to secudary fail over.

No needed for configure health check for S3 static website, only for ALB. Image if you have both health check and both of them unhealthy. In this scenarion no meaning of failover routing.

A and E ALB and S3 are both alias record so no need to create and associate additional health checks. Instead you configuring active-passive failover with one primary and one secondary resource.

D E The combination of actions that will meet these requirements is creating a primary failover routing policy record, configuring the value to be the ALB, and creating a secondary failover routing policy record, configuring the value to be the static website. This allows the SysOps administrator to use the static website as a backup to the web application, and automatically fail over to the static website if the health check fails. The administrator can also associate the record with a Route 53 health check to monitor the health of the web application and trigger the failover if necessary. Option A is not appropriate for this situation, as it does not include the secondary failover routing policy record that is necessary for automatic failover. Option B is not appropriate, as it does not involve configuring the routing policy records, which are necessary for directing traffic to the appropriate website. Option C is not appropriate, as it does not include the secondary failover routing policy record that is necessary for automatic failover.
