What is the benefit of using geo-replication in Azure SQL Database?

Using geo-replication in Azure SQL Database offers enhanced data availability and disaster recovery capabilities. This feature allows you to create readable secondary databases in different geographical regions. In the event of a regional outage or disaster, you can quickly failover to one of these secondary databases, ensuring minimal downtime and maintaining access to critical data.

Geo-replication not only provides an extra layer of security against data loss by having copies of your database in different locations, but it also improves the resilience of your database applications against regional service interruptions. This is particularly important for organizations that require high levels of service availability and rapid recovery from failures.

While other options may suggest enhancements or benefits related to speed, cost, or security, they do not accurately reflect the primary advantage of geo-replication, which specifically focuses on the availability of data and recovery capabilities in different geographical locations.
