You need to recommend a solution that ensures all VMs are redundant and deployable between locations. You also want the solution to minimize downtime in the event of an outage at either physical location.
Which solution should you recommend?
Configure a backup vault in Azure and use Data Protection Manager to back up The Windows Servers.
Use Data Protection Manager and back up the VMs in each location.
Use Azure site recovery in an on-premises to Azure protection configuration.
Use Azure site recovery in an on-premises to on-premises protection configuration.
Answer: D Explanation:
On-Premises to On-Premises (Hyper-V replication)
Replicated data is stored in location specified on target Hyper-V server.

You federate your on-premises Active Directory with Azure Active Directory (Azure AD) by using Active Directory Federations Services (AD FS) 2.0. You plan to secure cloud and on- premises resources by using an Azure Multi-Factor Authentication (MFA) server. You install the MFA server on the AD FS proxy server. You configure the MFA server and successfully import all AD users into the MFA user database.
Development teams in your organization must be able to secure their non-browser based apps.
You need to document the authentication mechanisms.
For each requirement, which authentication mechanism is used. To answer, select the appropriate authentication mechanism from each list in the answer area.
Securing Azure AD resources using Azure MFA First factor: performed on-premises using AD FS.
Second factor: phone-based method carried out using cloud authentication.
Securing Azure AD resources using Active Directory FS First factor: performed on-premises using AD FS.
Second factor: performed on-premises by honoring the claim.

a private IPv4 IP address and a RRAS running on Windows Server 2012
a public-facing IPv4 IP address and a compatible VPN device
a public-facing IPv4 IP address and a RRAS running on Windows Server 2012
Answer: C,D Explanation:
You must have an externally facing IPv4 IP address and a VPN device or RRAS to configure a site-to-site VPN connection.

You administer an Azure Virtual Machine (VM) named server1. The VM is in a cloud service named ContosoService1.
You discover that the VM is experiencing storage issues due to increased application logging on the server.
You need to create a new 256-GB disk and attach it to the server.
Which Power Shell cmdlets should you use? To answer, drag the appropriate cmdlet to the correct location in the Power Shell command. Each cmdlet may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
This example gets a virtual machine object for the virtual machine named 鈥淢yVM鈥?in the
鈥渕yservice鈥?cloud service, updates the virtual machine object by attaching an existing data disk from the repository using the disk name, and then updates the Azure virtual machine.
C:\PSgt;Get-AzureVM quot;myservicequot; -Name quot;MyVMquot; `| Add-AzureDataDisk -Import – DiskName quot;MyExistingDiskquot; -LUN 0 `| Update-AzureVM
Question No: 65
You manage an application running on Azure web apps in a Standard tier. The application uses a substantial amount of large image files from a storage account and is used by people around the world.
Users from Europe report that the load time of the site is slow. You need to implement a solution by using Azure services.
Which two actions will achieve the goal? Each correct answer presents a complete solution.
Configure Azure web app auto-scaling to increase instances at high load.
Configure Azure CDN to cache all responses from the application web endpoint.
Configure Azure CDN to cache site images and content stored in Azure blob storage.
Configure Azure blob storage with a custom domain.
Answer: B,C Explanation:
Question No: 66 DRAG DROP
Your company manages several Azure Web Sites that are running in an existing web- hosting plan named plan1.
You need to move one of the websites, named contoso, to a new web-hosting plan named plan2.
Which Azure PowerShell cmdlet should you use with each PowerShell command line? To answer, drag the appropriate Azure PowerShell cmdlet to the correct location in the PowerShell code. Each PowerShell cmdlet may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
The following command is actually a series of commands (delimited by semi-colons) that change the values of the properties in the $p variable.
PS C:\gt; $p.siteMode = quot;Basicquot;; $p.sku = quot;Basicquot;; $p.computeMode = quot;Dedicatedquot;;
$p.serverFarm = quot;Default2quot;
The next command uses the Set-AzureResource cmdlet to change the change the properties of the ContosoLabWeb2 web site. The value of the PropertyObject parameter is the $p variable that contains the Properties object and the new values. The command saves the output (the updated resource) in the $r2 variable.
PS C:\gt; $r2 = Set-AzureResource -Name ContosoLabWeb2 -ResourceGroupName ContosoLabsRG -ResourceType quot;Microsoft.Web/sitesquot; -ApiVersion 2004-04-01 – PropertyObject $p

You manage a large datacenter that has limited physical space. You plan to extend your datacenter to Azure.
You need to create a connection that supports a multiprotocol label switching (MPLS) virtual private network.
Which connection type should you use?
Answer: C Explanation:
ExpressRoute allows you to securely add compute and storage capacity to your existing datacenter. With high throughput and fast latencies, Azure will feel like a natural extension to your datacenter so you enjoy the scale and economics of the public cloud without having
to compromise on network performance.
Question No: 68
You are designing an Azure web application. The solution will be used by multiple customers. Each customer has different business logic and user interface requirements. Not all customers use the same version of the .NET runtime.
You need to recommend a deployment strategy. What should you recommend?
Deploy with multiple web role instances.
Deploy each application in a separate tenant.
Deploy all applications in one tenant.
Deploy with multiple worker role instances.
Answer: B Explanation:
There are two types of tenant environments. The simplest type is a single-tenant application where one customer has 100% dedicated access to an application’s process space. A single Tenant Applications has a separate, logical instance of the application for each customer or client. A single tenant application is much more predictable and stable by its nature since there will never be more than one dedicated customer at any point in time in that VM. That customer has all of its users accessing that dedicated instance of the application.

A Windows Azure application stores data in a SQL Azure database. The application will start an operation that includes three insert statements. You need to recommend an approach for rolling back the entire operation if the connection to SQL Azure is lost.
What should you recommend?
Ensure that all statements execute in the same database transaction.
Create a stored procedure in the database that wraps the insert statements in a TRY CATCH block
Create a stored procedure in the database that wraps the insert statements in a TRANSACTION block.
Open a new connection to the database. Use a separate transaction scope to roll back the original operation.
