Question: 1
HOTSPOT
You manage an Azure Service Bus for your company. You plan to enable access to the Azure Service Bus for an application named ContosoLOB
You need to create a new shared access policy for subscriptions and queues that has the following requirements:
In the table below, identify the permission you need to assign to ensure that ContosoLOB is able to accomplish the above requirements. Make only one selection in each column.
Answer:
For Service Bus, the three permission claims are Send for all send operations, Listen to open up listeners or receive messages, and Manage to observe or manage the state of the Service Bus tenant.
To receive a message from a queue we need to have Listen access level.
To numerate subscriptions, we need to have the manage access level.

Question: 3
You administer a cloud service named contosoapp that has a web role and worker role.
Contosoapp requires you to perform an in-place upgrade to the service.
You need to ensure that at least six worker role instances and eight web role instances are available when you apply upgrades to the service. You also need to ensure that updates are completed for all instances by using the least amount of time.
Which value should you use with each configuration? To answer, drag the appropriate value to the correct configuration. Each value 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.
Answer:
* You need to ensure that at least six worker role instances and eight web role instances are available when you apply upgrades to the service.
* You can decide whether you want to update all of the roles in your service or a single role in the service. In either case, all instances of each role that is being upgraded and belong to the first upgrade domain are stopped, upgraded, and brought back online. Once they are back online, the instances in the second upgrade domain are stopped, upgraded, and brought back online.

Question: 7
DRAG DROP
You manage an application hosted on cloud services. The development team creates a new version of the application. The updated application has been packaged and stored in an Azure Storage account.
You have the following requirements:
Which four steps should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Once you have uploaded the compiled package to Azure Storage, you would create a new staging deployment. You can then provide the URL to the development team. Once approved, you would promote the new deployment to production by performing a VIP swap. You can then stop the instance of the old production deployment and keep it at hand in the staging slot.

Question: 8
You manage a cloud service that utilizes data encryption.
You need to ensure that the certificate used to encrypt data can be accessed by the cloud service application.
What should you do?
A. Upload the certificate referenced in the application package.
B. Deploy the certificate as part of the application package.
C. Upload the certificates public key referenced in the application package.
D. Use RDP to install the certificate.

Question: 9
You administer a Windows Server virtual machine (VM).
You upload the VM to Azure.
You need to ensure that you are able to deploy the BGInfo and VMAccess extensions.
What should you do?
A. Select the Install the VM Agent checkbox while provisioning a VM based on your uploaded VHD.
B. Select the Enable the VM Extensions checkbox while provisioning a VM based on your uploaded VHD.
C. Install the VM Agent MSI and execute the following Power Shell commands:$vm = Get-AzureVM -serviceName $svc -Name $name$vm.VM.ProvisionGuestAgent = $trueUpdate-AzureVM -Name Sname -VM $vm.VM -ServiceName $svc
D. Install the VM Agent MSI and execute the following Power Shell commands:$vm = Get-AzureVM -serviceName $svc -Name $nameSet-AzureVMBGInfoExtension -VM $vm.VMSet-AzureVM Access Extension -VM $vm.VMUpdate-AzureVM -Name Sname -VM $vm.VM -ServiceName $svc
Answer: C
Explanation:
You are uploading a VM to Azure (not provisioning a VM from Azure so therefore needs the VM Agent MSI)
Is VM Agent installed?
$x = Get-AzureVM -ServiceName $vmName
$x.vm.ProvisionGuestAgent
If False
1. Install standalone VM Agent
2. Inform the Azure platform that the VM now has the agent installed
$vm = Get-AzureVM serviceName $svc Name $name $vm.VM.ProvisionGuestAgent = $TRUE Update-AzureVM Name $name -VM $vm.VM -ServiceName $svc

Question: 10
You manage a cloud service that supports features hosted by two instances of an Azure virtual machine (VM).
You discover that occasional outages cause your service to fail.
You need to minimize the impact of outages to your cloud service.
Which two actions should you perform? Each correct answer presents part of the solution.
A. Deploy a third instance of the VM.
B. Configure Load Balancing on the VMs.
C. Redeploy the VMs to belong to an Affinity Group.
D. Configure the VMs to belong to an Availability Set.
Answer: B,D
Explanation:
Adding your virtual machine to an availability set helps your application stay available during network failures, local disk hardware failures, and any planned downtime.
Combine the Azure Load Balancer with an Availability Set to get the most application resiliency. The Azure Load Balancer distributes traffic between multiple virtual machines.

Question: 11
You administer an Azure subscription with an existing cloud service named contosocloudservice. Contosocloudservice contains a set of related virtual machines (VMs) named ContosoDC, ContosoSQL and ContosoWeb1.
You want to provision a new VM within contosocloudservice.

Which PowerShell command should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation:
The New-AzureQuickVM cmdlet sets the configuration for a new virtual machine and creates the virtual machine. You can create a new Azure service for the virtual machine by specifying either the Location or AffinityGroup parameters, or deploy the new virtual machine into an existing service.
AdminUsername is not required.

Question: 12
DRAG DROP
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.
Answer:
This example gets a virtual machine object for the virtual machine named MyVM in the myservice 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.
Windows PowerShell
C:PS>Get-AzureVM “myservice” -Name “MyVM” `| Add-AzureDataDisk -Import -DiskName “MyExistingDisk” -LUN 0 `| Update-AzureVM
