   A healthcare organization wants to move its patient-portal application from one cloud provider to another to take advantage of lower data-residency costs in a specific region. The application is a set of containerized microservices with state stored in a managed database. The organization wants to minimize downtime and reconfiguration effort. Which approach best supports this application mobility goal?

   • AUse a container orchestration platform with a portable deployment manifest and migrate the stateful database using a replication or export/import mechanism.
   • BKeep the application in the current provider and use a CDN to serve content from the new region.
   • CRe-architect the application to be stateless and store all data in the new provider's proprietary object storage service.
   • DTake a snapshot of each VM and upload the images to the new provider's image registry.

   A company runs a stateful application on VMs in a private cloud. The company wants to move the application to a public cloud with minimal downtime. The application has a 500 GB database that is updated continuously. The company has a 1 Gbps network connection to the public cloud. Which migration approach minimizes downtime while ensuring data consistency?

   • AStop the application, copy the VM disks and database over the network, and then start the application in the cloud.
   • BMigrate the application code to the cloud and recreate the database from a backup taken the previous day.
   • CPerform an initial copy of the VM disks and database, then use continuous replication to sync changes until the final cutover, and switch traffic to the cloud.
   • DCopy the VM disks and database using a physical shipping device, then start the application in the cloud.
