A company is migrating a 5 TB on-premises database to the cloud. The database is actively used during business hours and the migration must not impact performance. The company has a 100 Mbps dedicated internet connection to the cloud provider. The migration window is limited to weekends. Which data migration strategy should the team choose?

Migrate the database schema first, then copy data row-by-row using a custom script during business hours.

Set up a continuous database replication link and cut over during the next business day.

Use a cloud provider's offline data transfer device to ship the initial full backup, then perform incremental syncs over the internet.

Perform a one-time full database backup and transfer it over the internet during the weekend window.

After migrating a database to a cloud-managed database service, the migration team needs to validate that the data was migrated correctly. The team has a list of row counts and checksums from the source database. Which validation step should the team perform?

Verify that the target database is accessible from the application server.

Run a performance test on the target database to ensure it can handle the expected load.

Compare the row counts and checksums of the source and target databases.

Check the cloud provider's status page to ensure the database service is operational.

After migrating a workload to the cloud, what is the purpose of conducting a smoke test?

To test the application under heavy load to determine performance limits

To verify that the basic functionality of the application works after migration

To check for security vulnerabilities in the application

To verify that all data has been encrypted
