A healthcare clinic is migrating its patient portal application to Microsoft Azure. The clinic has two primary requirements:
1. The application must remain accessible during localized hardware failures within a single datacenter.
2. The application must be capable of being restored in a secondary geographic region if a catastrophic natural disaster occurs.
Which two cloud concepts directly address these requirements? (Select two.)
- High availability, which keeps the application running during localized hardware or datacenter failures.Cevap
- Disaster recovery, which restores application services in a secondary region after a catastrophic regional outage.Cevap
- CElasticity, which automatically replicates application data to a secondary region to protect against disasters.
- DAvailability Zones, which protect against regional failures by spanning across multiple separate geographical regions.
Cevap
High availability keeps the application running during localized hardware failures, while disaster recovery restores services in a secondary region after a major outage.
The requirements are met by high availability, which ensures system uptime during localized failures, and disaster recovery, which provides a plan and infrastructure to restore services in another region during a catastrophic outage.
