Question

an organization is evaluating an application hosted on multiple virtual machines (vms) in azure. the it organization has mandated that the application must continue to function when a region - wide failure occurs in azure. which of the following accomplishes this obligation?
a azure stack
b elasticity
c disaster recovery
d on - premises model

Explanation:

• Azure Stack: It is a hybrid cloud platform for running Azure services on - premises. It is not related to handling region - wide Azure failures.
• Elasticity: Refers to the ability of a system to scale resources (up or down) based on demand. It does not address region - wide failures.
• Disaster recovery: Disaster recovery plans and solutions are designed to ensure that systems (like applications hosted on VMs) can continue to function in the event of a major disruption such as a region - wide failure.
• On - premises model: This is about running infrastructure within an organization's own physical location. It is not relevant to maintaining functionality during an Azure region - wide failure.

Answer:

C. Disaster recovery
