Zorluk: KolayReliability, Predictability, and Disaster Recovery

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.)

  1. High availability, which keeps the application running during localized hardware or datacenter failures.Cevap
  2. Disaster recovery, which restores application services in a secondary region after a catastrophic regional outage.Cevap
  3. C
    Elasticity, which automatically replicates application data to a secondary region to protect against disasters.
  4. D
    Availability 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.

Adım Adım Çözüm

1
Analyze the first requirement: ensuring accessibility during localized hardware failures.
Identify that localized resilience within a region is addressed by High Availability.
High availability is designed to protect against single points of failure, such as hardware, power, or cooling failures in a datacenter.
2
Analyze the second requirement: restoring services in a secondary region after a catastrophic natural disaster.
Identify that recovering from a regional disaster is addressed by Disaster Recovery.
Disaster recovery refers to the policies, tools, and procedures that enable the recovery or continuation of vital infrastructure and systems following a natural or human-induced disaster.
