A cross-region read replica is a read replica created in a different region from the primary Cloud SQL instance to improve read performance, assist migration, or support disaster recovery. On Associate Data Practitioner it comes up as a disaster recovery and read scalability mechanism within the data management domain when evaluating regional availability trade-offs.

What you can expect on the exam

Disaster recovery and high availability pairing. Be ready to assess how combining a cross-region replica with high availability protects a Cloud SQL deployment against both zonal and regional failures.
Failover capabilities in Enterprise Plus. Expect to recognize how Cloud SQL Enterprise Plus edition uses a cross-region replica to support advanced disaster recovery with zero data loss during failover.
Promotion during regional failover. You may need to understand how disaster recovery can be accomplished by promoting a cross-region read replica to a standalone instance in another region.
Replication data transfer costs. Know that operating a cross-region replica incurs network egress charges for replication logs transmitted from the primary instance to the replica instance.
