A county emergency archive must replicate Blob data to a secondary Azure region for disaster recovery. Which redundancy concept fits at describe level?
Select an answer to reveal the explanation.
Short Explanation
When the county says “another region,” think geo—GRS (and related geo options) copy data to a paired secondary region. LRS stays local; Hot is just an access tier, not a plane ticket to another geography. File Sync is a hybrid file story, not the blob geo-redundancy label.
Full Explanation
Geo-redundant storage (GRS) replicates data asynchronously to a secondary region, supporting regional disaster-recovery scenarios for Azure Storage. Related options such as RA-GRS add read access in the secondary region, but the core AZ-900 idea is geo-replication beyond the primary region. LRS does not provide cross-region copies, and access tiers do not themselves create geo-redundancy. Candidates should map a secondary-region requirement to a geo-redundant storage option.
