An online education platform is designing a storage solution for video course materials using Azure Blob Storage. The solution must meet the following requirements:
- Replicate data across three availability zones in the primary region to protect against a zone outage.
- Replicate data to a secondary region to protect against a regional disaster.
Which two redundancy configuration options should you recommend? (Select two.)
- Geo-zone-redundant storage (GZRS)Answer
- Read-access geo-zone-redundant storage (RA-GZRS)Answer
- CGeo-redundant storage (GRS)
- DZone-redundant storage (ZRS)
- ELocally redundant storage (LRS)
Answer
Geo-zone-redundant storage (GZRS) and Read-access geo-zone-redundant storage (RA-GZRS)
The correct options are Geo-zone-redundant storage (GZRS) and Read-access geo-zone-redundant storage (RA-GZRS). These tiers replicate data across three Azure availability zones in the primary region, which protects against zone outages, and asynchronously replicate it to a secondary region, which protects against regional disasters.
