An organization requires that its application remain available even if an entire Azure region suffers a complete outage. Which cloud benefit directly addresses this?
Show answer and explanation
Answer: C
Surviving the loss of an entire region requires disaster-recovery design built on geo-redundancy: running the application in a second region with data replicated so it can serve traffic there. Deploying into a region pair supports such designs, though replication and failover must be configured through the chosen services and the architecture itself.
Scalability and agility describe capacity and speed of deployment, and elasticity only adjusts resources that remain within the deployed footprint.
Why the other options are wrong
- A. Scalability is about handling increased load by adding capacity, which does nothing for the application when its whole host region is down.
- B. Agility is the speed at which new resources can be provisioned; deploying quickly does not keep a service running through a regional failure.
- D. Elasticity adjusts capacity to match demand but stays within the regions already deployed to, so it cannot rescue the application from a region-wide outage.
