Difficulty: MediumReliability, Predictability, and Disaster Recovery

A health insurance provider needs to design its customer portal so that if a catastrophic event causes a complete outage of an entire primary Azure region, the portal can be restored and data recovered in a secondary region. Which cloud concept is represented by this requirement?

  1. Disaster recoveryAnswer
  2. B
    High availability
  3. C
    Elasticity
  4. D
    Availability Zone replication

Answer

Disaster recovery
The correct answer is Disaster Recovery because it is specifically designed to handle catastrophic events and wide-scale outages (such as the loss of an entire region) by recovering systems and data in a separate location.

Step-by-Step Solution

1
Analyze the requirement of recovering from an outage of an entire primary Azure region to a secondary region.
Identify that this represents recovering from a large-scale catastrophic failure.
To determine whether the solution requires regional recovery or local resilience.
2
Compare the definitions of High Availability, Disaster Recovery, Elasticity, and Availability Zones.
Confirm that Disaster Recovery is the concept dedicated to restoring services and data in a secondary region after a catastrophic regional event.
To map the requirement to the correct Azure cloud concept.
