Each question shows the correct answer and an explanation of why it is right
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 reduced 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.
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 don't need to.
Which service provides serverless computing in Azure?
The correct answer is Azure Functions.
Azure Functions is Microsoft's primary serverless computing service in Azure:
Other serverless services in Azure include Azure Logic Apps and Azure App Service Plan with consumption tier, but Azure Functions is the primary and most commonly used serverless computing offering.
You plan to map a network drive from several computers that run Windows 10 to Azure Storage. You need to create a storage solution in Azure for the planned mapped drive.
What should you create?
Azure Files is Microsoft's easy-to-use cloud file system. Azure file shares can be seamlessly used in Windows and Windows Server.
To use an Azure file share with Windows, you must either mount it, which means assigning it a drive letter or mount point path, or access it via its UNC path.
Unlike other SMB shares you may have interacted with, such as those hosted on a Windows Server, Linux Samba server, or NAS device, Azure file shares do not currently support Kerberos authentication with your Active Directory (AD) or Azure Active Directory (AAD) identity, although this is a feature we are working on. Instead, you must access your Azure file share with the storage account key for the storage account containing your Azure file share. A storage account key is an administrator key for a storage account, including administrator permissions to all files and folders within the file share you're accessing, and for all file shares and other storage resources (blobs, queues, tables, etc) contained within your storage account.

You have an on-premises network that contains several servers.
You plan to migrate all the servers to Azure.
You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period.
What should you include in the recommendation?
Fault tolerance is the ability of a system to continue to function in the event of a failure of some of its components.
In this question, you could have servers that are replicated across datacenters.
Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures.
With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

This question requires that you evaluate the underlined text to determine if it is correct.
An Availability Zone in Azure has physically separate locations across two continents.
Instructions: Review the underlined text. If it makes the statement correct, select ''No change is needed.'' If the statement is incorrect, select the answer choice that makes the statement correct.
Availability Zones is a high-availability offering that protects your applications and data from datacenter
failures. Availability Zones are unique physical locations within an Azure region.

What is the longest term you can purchase for Azure Reserved VM Instances?
The longest term you can purchase for Azure Reserved VM Instances is 3 years. You can also purchase 1-year reservations. The 3-year commitment provides a greater discount compared to 1-year terms.
What does a customer provide in a software as a service (SaaS) model?
In a Software as a Service (SaaS) model, the customer provides only data. The SaaS provider manages and maintains the application, platform, infrastructure, security, and all other operational aspects. The customer is responsible only for the data they input into the application.
