16 – Question

You plan to migrate multiple servers from your local network to Azure. What are the advantages of moving servers from a local network to a public cloud service?

A. Public clouds are owned by the public, not private companies

B. Public cloud is a crowdsourcing solution that enhances cloud capabilities for enterprises

C. All public cloud resources are accessible to the public for free

D. A public cloud is a shared entity in which multiple companies each use a portion of the resources in the cloud

16 – Answer

The correct answer is D

A public cloud is a shared entity, with multiple companies each using a portion of the cloud’s resources. Hardware resources (servers, infrastructure, and so on) are managed by the cloud provider. Multiple companies create resources such as virtual machines and virtual networks on these hardware resources.

Incorrect answers:

A: Public clouds are not owned by the public. In the case of Microsoft Azure, the cloud is owned by Microsoft.

B: Public clouds are not crowdsourced solutions. In the case of Microsoft Azure, the cloud is owned by Microsoft.

C: It is not true that public cloud resources are freely accessible to every member of the public. You need to pay for cloud resources and create an account to access your cloud resources. No one can access your cloud resources until you create an account and provide the appropriate access rights.

20 – Question

You have 1,000 virtual machines hosted on hyper-V hosts in your data center. You plan to migrate all virtual machines to Azure pay-as-you-go subscription services. You need to determine the expenditure model to be used for the planned Azure solution. Which spending model should you decide on?

A. the operation

[B] elastic

C. the capital

[D]

20 – Answer

The correct answer is A

When you move from on-premise to public cloud, one of the major changes you will face is a shift from capital expenditure (buying hardware) to operational expenditure (paying for services as you use them). This transformation also requires more careful management of your costs. The beauty of the cloud is that you can radically reduce the cost of the services you use by simply turning it off or resize when you don’t need it.
