Answer: fault tolerance
The correct answer is 'A' - fault tolerance. Fault tolerance is the capability of a system to continue operation even if one or more components fail. In the context of Azure, ensuring fault tolerance involves replicating servers across different availability zones or regions. Availability Zones are unique physical locations within an Azure region that ensure resilience and continuous service availability in the event of a data center failure. By architecting solutions with fault tolerance, applications and data remain accessible even if a single data center goes offline.
