1. By configuring load balancing between the VMs.
2. By moving the VMs to the Azure Basic tier.
3. By removing any orphaned VHDs.

Correct Answer : 3
Explanation: Using Azure PowerShell, we can easily clean up disks that are unused. You could implement this PowerShell script as an automated task through the Microsoft
Azure Automation feature, which is still in preview as of this writing. Azure Automation is a script-as-a-service feature of the Azure platform that allows you to execute PowerShell
Workflows (also known as Runbooks) directly from Azure. Using this service, you can ensure that your Azure subscriptions are well-managed automatically.

Of course, if you implement any automated clean-up processes like this, you'll want to make sure that you have a backup plan, and communicate to the rest of your team that this
process will be executed on a scheduled basis. If other team members are not aware of this process, they might leave orphaned disks out there unintentionally, thinking that they
won't be cleaned up automatically.
Here is a script that we can use to perform the automated cleanup. If you want to wrap this script inside a PowerShell Workflow, you could easily do that as well. However, the
Where()
and
ForEach()
methods may not be suitable for Workflows.

# Authenticate to the Microsoft Azure platform $Username = 'trevor@trevorsullivan.net'; # Change this to your Azure Active Directory organizational account username. $AzureCredential
= Get-Credential -UserName $Username -Message 'Please enter your Azure password.'; Add-AzureAccount -Credential $AzureCredential; # Find and remove unused Azure disks
(Get-AzureDisk).Where({ !$PSItem.AttachedTo; }).ForEach({ Remove-AzureDisk -DiskName $PSItem.DiskName -DeleteVHD; });
After running the script above, you will have cleaned up your unused Azure VHD. The output from the
Remove-AzureDisk
command looks similar to the following screenshot.








Question : Your role of Systems Administrator at ABC.com includes the management of the company's virtual infrastructure. The company has virtual machines running in an
on-premise virtual environment and in Microsoft Azure.
You plan to deploy several new virtual machines (VMs) in Azure. The VMs will have the same operating system and custom software requirements.
You configure a reference VM in the on-premise virtual environment. You then generalize the VM to create an image. You need to upload the image to Azure to ensure that it is
available for selection when you create the new Azure VMs. Which of the following PowerShell cmdlets should you use?

1. Add-AzureDisk
2. Add-AzureVhd
3. Add-AzureVMImage
4. Add-AzureDataDisk



Correct Answer : 3
Explanation: The Add-AzureVMImage cmdlet adds an operating system image to the image repository. The image should be a generalized operating system image, using either
Sysprep for Windows or, for Linux, using the appropriate tool for the distribution.







Question : You work for a company named ABC.com. Your role as Cloud Administrator includes the management of the company's public and private cloud infrastructure.
The company has a development department. Developers have created three new web applications that will be used by company employees and customers.
You plan to host the web applications on Azure cloud services. You need to guarantee availability of the web applications to the customers by ensuring that all
three web applications meet the requirements for the Azure SLA (Service Level Agreement). You need to determine how to deploy the web applications to Azure. Your solution must
minimize costs and meet the requirements for the Azure SLA. Which two of the following statements are true? (Choose two)
A. Each web application must be deployed in a separate web role.
B. All three web applications can be deployed into a single web role.
C. There must be at least one instance per web role.
D. There must be at least two instances per web role.
E. There must be at least three instances per web role.

Correct Answer : 3

Explanation: Web and Worker roles are nearly identical:

Web roles are Windows 2012 VMs with IIS enabled
Worker roles are Windows 2012 VMs with IIS disabled (and you could manually enable it)
VM roles are Windows Server 2008 images you construct locally via Hyper-V and upload to Azure (and are now discontinued and no longer available as of May 31, 2013
Virtual Machines are Windows or Linux images created in Azure, stored as a vhd in your own storage, and have several enhancements over VM role. For example: since the vhd is in your
own storage account, you can easily create an image template from your vhd, copy it to a new vhd, or even upload it to VM Depot (Linux only).
To answer your question about what to do with these roles: The Platform Training kit (mentioned below) will give you lots of good ideas and samples, but here are some straightforward
use cases:

You can run any code that exposes a tcp, http, https, or udp endpoint (web applications, SOAP/REST services, etc.). You need to think about the stateless way of doing things though -
if you have more than one VM instance running, user traffic is distributed across those instances. The platform training kit will show you how to use storage or cache to deal with
this. You can run code that lives off a queue or a timer. Maybe you have on-demand tasks such as thumbnail-generation of photos, or calculations based on user input. These don't need
externally-available endpoints. You can push your requests to a queue, and then have a task running which simply feeds off this queue (and you can scale this process across multiple
instances, with queue messages consumed by all instances).
You can run .NET, Java, php, python, node, ruby, etc. You just need to distribute the appropriate runtime code along with your project code. All languages can make REST calls to the
Azure API, and several languages (including those mentioned above) have SDKs that take care of this for you. All language SDKs are here, with source code on github, here.
With a VM role, you can install and run software with very complex/time-consuming installations, installations that require manual intervention, and installations that can't be
reliably automated. You must deal with OS maintenance in this case. Beyond VM Role, there are now Virtual Machines, providing cloud-based VM construction along with both Windows and
Linux support. I'd suggest Virtual Machines over VM Role.
With Web and Worker roles, the OS and related patches are taken care of for you; you build your app's components without having to manage a VM. With VM roles, you build a complete
Windows Server 2012 image, add the Windows Azure hooks to it, and push the entire VM into the cloud (and then maintain the VM image over time). With Virtual Machines, you simply
pick an OS image from a gallery, which gets created for you and stored as a vhd in blob storage. You then RDP/ssh and set it up how you like.

Wearing the architect hat, this is where it gets fun and interesting. You can run web services in a Web Role or worker role (and be able to open ports in either); You can host Tomcat
or other web servers in a Worker role. you can choose to combine a website plus services in a single role, or split them into multiple roles for different scalability needs.
