GCP Professional Data Engineer Practice Question

A healthcare provider must migrate a 50 TB on-premises MySQL database to Cloud SQL for MySQL using Database Migration Service (DMS). The migration has two non-negotiable requirements:

  • Continuous data replication is needed to keep cut-over time under 5 minutes.
  • Patient-data traffic must stay off the public internet and sustain at least 10 Gbps throughput during the bulk-load phase.

Which network connectivity approach best satisfies these constraints while keeping operational overhead low?

  • Provision a Dedicated Cloud Interconnect to the Google Cloud VPC and configure DMS to use private connectivity over the Interconnect link.

  • Establish an HA Cloud VPN tunnel and configure DMS to use public IP connectivity with source IP allow-listing.

  • Export the database to encrypted dump files, transfer them with Transfer Appliance to Cloud Storage, then import into Cloud SQL after shipment.

  • Run DMS over standard internet links using public IP connectivity and protect traffic with SSL/TLS during transit.
