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?
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.
Geo-redundant storage is incorrect. GRS stores data in secondary locations but doesn't allow read access from the secondary.
Locally redundant storage is incorrect. LRS stores data on multiple nodes within a single datacenter, not separate geographic locations.
Zone-redundant storage is incorrect. ZRS replicates across availability zones within a single region, not separate geographic locations.
