You need to create a storage account that meets the following requirements:

✑ Remains available if a single data center in the region fails.
How should you configure the storage account? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Accepted Answer

1. **Replication (ZRS):** Zone-redundant storage (ZRS) replicates your data synchronously across three Azure availability zones (which represent unique physical data centers with independent power, cooling, and networking) within the primary region. This satisfies the requirements of synchronous replication and remaining available if a single data center fails. LRS only replicates inside a single data center (cannot survive a data center failure). GRS/RA-GRS replication to the secondary region is asynchronous.
2. **Account type (StorageV2):** General-purpose v2 (GPv2) is the standard storage account type that fully supports standard ZRS replication. Older GPv1 and classic Blob storage accounts do not support standard ZRS.
