Designing an Azure Data Solution (legacy) — Question 2

A company is designing a solution that uses Azure Databricks.
The solution must be resilient to regional Azure datacenter outages.
You need to recommend the redundancy type for the solution.
What should you recommend?

Answer options

• A. Read-access geo-redundant storage
• B. Locally-redundant storage
• C. Geo-redundant storage
• D. Zone-redundant storage

Correct answer: C

Explanation

Geo-redundant storage (GRS) is the most suitable option because it replicates data across geographically distant regions, providing resilience against regional outages. Locally-redundant storage (LRS) only protects against localized failures, while zone-redundant storage (ZRS) offers redundancy within a single region, and read-access geo-redundant storage (RA-GRS) provides read access to data in a secondary region but is not primarily focused on resiliency against outages.
