What is the main reliability benefit a customer gets from running a workload in a public cloud like Azure compared to a single on-premises datacenter?
ARemoval of the shared responsibility model entirely
BGuarantee that the workload never needs to be tested or monitored
CConversion of all monthly bills into a one-time payment
DAccess to multiple geographically separated regions and availability zones for fault isolation
Answer & Solution
Correct answer: D. Access to multiple geographically separated regions and availability zones for fault isolation
Public cloud providers offer many regions and AZs that the customer can spread a workload across for fault isolation — far beyond what a single on-prem datacenter can provide on its own. The other options misstate reliability, responsibility, or billing.
