Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.
An organization hosts mission-critical business reports in an Azure Storage account. The organization requires protection against regional disasters by copying data asynchronously to a secondary paired region hundreds of miles away.
In addition, client applications distributed globally need immediate, continuous read access to the data in the secondary region at all times, without waiting for or initiating an account failover.
Which Azure Storage redundancy option should the organization select?
Read-access geo-redundant storage (RA-GRS) is an Azure Storage redundancy option that provides cross-region replication while exposing a dedicated secondary endpoint for read access. Like standard Geo-redundant storage (GRS), RA-GRS synchronously writes data three times within a single physical location in the primary region using Locally-redundant storage (LRS), and then asynchronously replicates that data to a secondary paired region hundreds of miles away.
