An IT administrator is planning a migration to Microsoft Azure and wants to align the new infrastructure with cloud design principles. Which two statements about reliability and predictability in Azure are correct?
- Reliability ensures that an application can recover from infrastructure failures and continue to function.Cevap
- Predictability allows a company to forecast billing costs and maintain consistent application performance.Cevap
- CDisaster recovery is the mechanism used to maintain maximum uptime of resources during a localized network disruption within a single Availability Zone.
- DPredictability is the ability of an application to automatically scale resources up and down to match demand fluctuations.
Cevap
The correct statements are that reliability ensures an application can recover from infrastructure failures and continue to function, and predictability allows a company to forecast billing costs and maintain consistent application performance.
The correct statements accurately define reliability and predictability. Reliability represents the capacity of a system to recover from failures and maintain operational status. Predictability describes the capability to maintain a consistent user experience (performance predictability) and reliably forecast monthly or annual spending (cost predictability).
