MDFT Academy Quizzes

Choose the correct Azure storage redundancy

MDFT Academy has a Microsoft Azure subscription with resources in two datacenters in geo-paired regions. You are configuring the resources as geo-clustered sites for site resiliency.

You need to recommend an Azure storage redundancy option.

You have the following data storage 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 of the following Azure storage redundancy options should you recommend?

Choose the correct answer from the options below.

Explanations for each answer:

Geo-redundant storage (GRS) is incorrect. While geo-redundant storage (GRS) replicates data to a secondary region, it does not provide read access to the data in the secondary location. This does not meet the requirement for data to be readable from the secondary location.
Read-only geo-redundant storage (RA-GRS) is correct
Zone-redundant storage (ZRS) is incorrect. Zone-redundant storage (ZRS) replicates data across availability zones within a single region. This does not meet the requirement for data to be stored in separate geographic locations.
Locally redundant storage (LRS) is incorrect. Locally redundant storage (LRS) only replicates data within a single data center. This does not meet the requirements for data to be stored in separate geographic locations.
