Which strategy is commonly used in a hybrid cloud design to ensure that if the primary on-premises data center fails, the cloud environment can take over?

Keeping all data on-premises and only using the cloud for testing

Disabling cloud resources to save costs

Using a single load balancer in the on-premises data center

Replicating data to the cloud and maintaining a standby environment there

A company runs a batch processing application that runs for 30 minutes every hour. The application is CPU-intensive and runs on a single virtual machine. The company wants to reduce costs while maintaining the ability to process the batch job within the hour. Which solution should they implement?

Use a larger VM instance type to process the batch job faster and then stop the VM.

Keep the virtual machine running 24/7 to ensure it is always available to process the batch job.

Use a scheduled auto-scaling policy to start the VM 30 minutes before the batch job is scheduled to run and stop it after the job completes.

Use a serverless compute service that scales to zero when the job is not running and scales up to process the batch job.
