Answer: Read-only geo-redundant storage
Based on the requirements: data must be stored on multiple nodes, data must be stored on nodes in separate geographic locations, and data can be read from both the primary and secondary locations. The best option is Read-only geo-redundant storage (RA-GRS). RA-GRS allows data to be read from the secondary location even when the primary location is still accessible, providing higher availability compared to other options. Geo-redundant storage (GRS) would replicate the data to a secondary location, but it is only accessible if a failover to the secondary region is initiated, making it less suitable for the need to read from both locations at any time.

You are tasked with configuring these datacenters as geo-clustered sites to enhance site resiliency. To achieve this, you need to recommend an Azure storage redundancy option that ensures the following: ✑ Data is stored across multiple nodes. ✑ Data is replicated across nodes in distinct geographic locations. ✑ Data can be accessed for reading from both the primary and secondary locations. Which Azure storage redundancy option would you recommend to meet these criteria?
A
Geo-redundant storage
B
Read-only geo-redundant storage
C
Zone-redundant storage
