Mark, the CTO of MDFT Pro, has asked you to configure the company's two datacenters in Los Angeles and New York as geo-clustered sites for site resiliency. You need to recommend an Azure storage redundancy option that meets the following requirements:
- Data must be stored on multiple nodes
- Data must be stored on nodes in separate geographic locations
- Data can be read from the secondary location as well as from the primary location
Which Azure storage redundancy option should you recommend?
Locally redundant storage is incorrect. LRS stores data on multiple nodes within a single datacenter, not separate geographic locations.
Geo-redundant storage is incorrect. GRS stores data in secondary locations but doesn't allow read access from the secondary.
Read-only geo-redundant storage is correct. RA-GRS meets all requirements: multiple nodes, separate geographic locations, and read access from both primary and secondary.
Zone-redundant storage is incorrect. ZRS replicates across availability zones within a single region, not separate geographic locations.
