Difficulty: EasyReliability, Predictability, and Disaster Recovery

An administrator claims that implementing a disaster recovery (DR) plan is the primary method to ensure that an Azure-hosted application remains continuously available and running without any downtime during a localized hardware failure.

Answer: Answer

Answer

False
The claim is false because the described functionality—maintaining continuous uptime during localized hardware failures—is the definition of High Availability. Disaster Recovery is focused on restoring application function and data after a major event, which generally involves an acceptable period of downtime.

Step-by-Step Solution

1
Analyze the administrator's claim about maintaining continuous availability with no downtime during localized failures.
The claim states that a disaster recovery plan is the primary method for achieving this.
To identify the specific cloud concept being referenced in the scenario.
2
Compare the scenario description with the definitions of High Availability (HA) and Disaster Recovery (DR).
Maintaining continuous operations and preventing downtime during local hardware failures is the definition of High Availability. Disaster Recovery is about recovering from catastrophic events and restoring service, which often accepts some downtime.
To determine if the administrator's statement is correct.
