Your company has datacenters in Los Angeles and New York. The company has a Microsoft Azure subscription.
You are configuring the two datacenters as geo-clustered sites for site resiliency.
You need to recommend an Azure storage redundancy option.
You have the following data storage requirements:
✑ Data must be stored on multiple nodes.
✑ Data must be stored on nodes in separate geographic locations.
✑ Data can be read from the secondary location as well as from the primary location
Which of the following Azure stored redundancy options should you recommend?
Read-only geo-redundant storage
RA-GRS allows you to have higher read availability for your storage account by providing ג€read onlyג€ access to the data replicated to the secondary location. Once you enable this feature, the secondary location may be used to achieve higher availability in the event the data is not available in the primary region. This is an
ג€opt-inג€ feature which requires the storage account be geo-replicated.
Your company’s Azure subscription includes a Basic support plan.
They would like to request an assessment of an Azure environment’s design from Microsoft. This is, however, not supported by the existing plan.
You want to make sure that the company subscribes to a support plan that allows this functionality, while keeping expenses to a minimum.
Solution: You recommend that the company subscribes to the Professional Direct support plan.

Your company is planning to migrate all their virtual machines to an Azure pay-as-you-go subscription. The virtual machines are currently hosted on the Hyper-V hosts in a data center.
You are required make sure that the intended Azure solution uses the correct expenditure model.
Solution: You should recommend the use of the elastic expenditure model.
Does the solution meet the goal?
No,
Elasticity is not an expenditure model rather is one of the characteristics of could computing. The basic advantage of cloud computing is shifting your high Capital Expenditure (CAPEX) requirements to optimal Pay -As-You-Go model which is Operational Expenditure (OPEX)
Your company is planning to migrate all their virtual machines to an Azure pay-as-you-go subscription. The virtual machines are currently hosted on the Hyper-V hosts in a data center.
You are required make sure that the intended Azure solution uses the correct expenditure model.
Solution: You should recommend the use of the scalable expenditure model.
Does the solution meet the goal?
No,
Because we have two expenditure models. One is Cap-Ex, another is Op-Ex. So Scalable Expenditure is not the right answer.
