Your company hosts an accounting application named App1 that is used by all the customers of the company. App1 has low usage during the first three weeks of each month and very high usage during the last week of each month. Which benefit of Azure Cloud Services supports cost management for this type of usage pattern?

high availability
high availability
high latency
high latency
elasticity
elasticity
load balancing
load balancing
Suggested answer: C
Explanation:

Elasticity in this case is the ability to provide additional compute resource when needed and reduce the compute resource when not needed to reduce costs. Autoscaling is an example of elasticity. Elastic computing is the ability to quickly expand or decrease computer processing, memory and storage resources to meet changing demands without worrying about capacity planning and engineering for peak usage. Typically controlled by system monitoring tools, elastic computing matches the amount of resources allocated to the amount of resources actually needed without disrupting operations. With cloud elasticity, a company avoids paying for unused capacity or idle resources and doesn't have to worry about investing in the purchase or maintenance of additional resources and equipment.

You plan to migrate a web application to Azure. The web application is accessed by external users.

You need to recommend a cloud deployment solution to minimize the amount of administrative effort used to manage the web application. What should you include in the recommendation?

Software as a Service (SaaS)
Software as a Service (SaaS)
Platform as a Service (PaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS)
Database as a Service (DaaS)
Database as a Service (DaaS)
Suggested answer: B
Explanation:

Azure App Service is a platform-as-a-service (PaaS) offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises. App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile Services.

Question 284

You have an on-premises network that contains 100 servers.

You need to recommend a solution that provides additional resources to your users. The solution must minimize capital and operational expenditure costs. What should you include in the recommendation?

a complete migration to the public cloud
a complete migration to the public cloud
an additional data center
an additional data center
a private cloud
a private cloud
a hybrid cloud
a hybrid cloud
Suggested answer: D
Explanation:

A hybrid cloud is a combination of a private cloud and a public cloud.

Capital expenditure is the spending of money up-front for infrastructure such as new servers.

With a hybrid cloud, you can continue to use the on-premises servers while adding new servers in the public cloud (Azure for example). Adding new servers in Azure minimizes the capital expenditure costs as you are not paying for new servers as you would if you deployed new server on-premises.

Incorrect Answers:

A: A complete migration of 100 servers to the public cloud would involve a lot of operational expenditure (the cost of migrating all the servers). B: An additional data center would involve a lot of capital expenditure (the cost of the new infrastructure). C: A private cloud is hosted on on-premises servers to this would involve a lot of capital expenditure (the cost of the new infrastructure to host the private cloud).

Question 285

You plan to migrate several servers from an on-premises network to Azure.

What is an advantage of using a public cloud service for the servers over an on-premises network?

The public cloud is owned by the public, NOT a private corporation
The public cloud is owned by the public, NOT a private corporation
The public cloud is a crowd-sourcing solution that provides corporations with the ability to enhance the cloud
The public cloud is a crowd-sourcing solution that provides corporations with the ability to enhance the cloud
All public cloud resources can be freely accessed by every member of the public
All public cloud resources can be freely accessed by every member of the public
The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud
The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud
Suggested answer: D
Explanation:

The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud. The hardware resources (servers, infrastructure etc.) are managed by the cloud provider. Multiple companies create resources such as virtual machines and virtual networks on the hardware resources.

Incorrect Answers:

A: The public cloud is not owned by the public. In the case of Microsoft Azure, the cloud is owned by Microsoft. B: The public cloud is a not crowd-sourcing solution. In the case of Microsoft Azure, the cloud is owned by Microsoft. C: It is not true that public cloud resources can be freely accessed by every member of the public. You pay for a cloud subscription and create accounts for your users to access your cloud resources. No one can access your cloud resources until you create user accounts and provide the appropriate access permissions.
