Zorluk: OrtaReliability, Predictability, and Disaster Recovery

A smart agriculture company hosts its global sensor data processing solution in Azure. The solution must meet the following operational requirements:
- The system must remain operational and recover its data in a different geographic region if the primary region suffers a complete, catastrophic outage.
- The deployment template must ensure that application performance and resource costs remain consistent and within expected thresholds across testing and production environments.

Which two cloud concepts are directly demonstrated by these requirements? (Select TWO.)

  1. PredictabilityCevap
  2. Disaster RecoveryCevap
  3. C
    Fault Tolerance
  4. D
    Scalability

Cevap

Predictability and Disaster Recovery are the correct concepts.
The requirement to recover data and restore operations in a different region after a catastrophic regional outage represents Disaster Recovery. The requirement to maintain consistent performance and cost behavior across multiple environments represents Predictability.

Adım Adım Çözüm

1
Analyze the first requirement regarding regional outage recovery.
Identify that recovering from a catastrophic regional outage in a separate geographic region represents disaster recovery rather than fault tolerance.
Disaster recovery involves failing over to another region to restore service after a disaster, whereas fault tolerance keeps systems up and running during localized component failures within a region.
2
Analyze the second requirement regarding performance and cost consistency.
Identify that ensuring consistent performance and resource costs across different environments is a benefit of predictability.
Predictability in the cloud can be configuration-based (ensuring templates deploy identical environments) or cost-based (ensuring costs are forecastable and consistent).
