Your company has an on-premises network that contains multiple servers.
The company plans to reduce the following administrative responsibilities of network administrators:
✑ Backing up application data
✑ Replacing failed server hardware
✑ Managing physical server security
✑ Updating server operating systems
✑ Managing permissions to shared documents
The company plans to migrate several servers to Azure virtual machines.
You need to identify which administrative responsibilities will be eliminated after the planned migration.
Which two responsibilities should you identify? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A. Replacing failed server hardware
B. Backing up application data
C. Managing physical server security
D. Updating server operating systems
E. Managing permissions to shared documents

Suggested Answer: AC
Azure virtual machines run on Hyper-V physical servers. The physical servers are owned and managed by Microsoft. As an Azure customer, you have no access to the physical servers. Microsoft manage the replacement of failed server hardware and the security of the physical servers so you donג€™t need to.
Incorrect Answers:
B: Microsoft have no control over the applications you run on the virtual machines. Therefore, it is your responsibility to ensure that application data is backed up.
D: Microsoft do not manage the operating systems you run on the virtual machines. Therefore, it is your responsibility to ensure that the operating systems are updated.
E: Microsoft have no control over the shared folders you host on the virtual machines. Therefore, it is your responsibility to ensure that folder permissions are configured appropriately.

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?

A. high availability
B. high latency
C. elasticity
D. load balancing

Correct Answer: C

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 doesnג€™t have to worry about investing in the purchase or maintenance of additional resources and equipment.

B. Platform as a Service (PaaS)
C. Infrastructure as a Service (IaaS)
D. Database as a Service (DaaS)

Correct Answer: B

App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile
