The correct answer is D. geo-redundant storage (GRS). The difference between GRS and RA GRS is fairly simple, GRS only allows to be read in the secondary zone in the even of a failover from the primary to secondary while RA GRS allows the option to read in the secondary whenever.
Question
You have an Azure Data Lake Storage Gen2 container that contains 100 TB of data. You need to ensure that the data in the container is available for read workloads in a secondary region if an outage occurs in the primary region. The solution must minimize costs. Which type of data redundancy should you use?
Options
- Azone-redundant storage (ZRS)
- Bread-access geo-redundant storage (RA-GRS)
- Clocally-redundant storage (LRS)
- Dgeo-redundant storage (GRS)
