Architecting Microsoft Azure Solutions
Question No: 41 – (Topic 6)
You are designing an Azure application. The application includes two web roles and three instances of a worker role. The web roles send requests to the worker role by using one or more Azure Queues.
You need to recommend a queue design for sending requests to the worker role. What should you recommend?
Create a queue for each combination of web roles and worker role instances. Send requests to all worker role instances based on the sending web role.
Create a single queue. Send all requests on the single queue.
Create a queue for each worker role instance. Send requests on each worker queue by using a round robin rotation.
Create a queue for each web role. Send requests on all queues at the same time.
Explanation: To communicate with the worker role, a web role instance places messages on to a queue. A worker role instance polls the queue for new messages, retrieves them, and processes them. There are a couple of important things to know about the way the queue service works in Azure. First, you reference a queue by name, and multiple role
instances can share a single queue. Second, there is no concept of a typed message; you construct a message from either a string or a byte array. An individual message can be no more than 64 kilobytes (KB) in size.

You have a website that displays text, pictures, video files, and audio files. The website processes requests from countries and regions all over the world. You plan to migrate the website to the Azure platform.
The website has the following requirements:
->Encode, store, and stream audio and video at scale.
->Load-balance communications with the website instance that is closest to the user#39;s location.
->Deliver content with high-bandwidth and low latency.
You need to recommend the technologies to implement the solution.
Which technologies should you recommend? To answer, drag the appropriate technology to the correct requirement. Each technology 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.
Azure Media Services is being used to power consumer and enterprise streaming solutions worldwide. Combining powerful and highly scalable cloud-based encoding, encryption and steaming components, Azure Media Services is helping customers with valuable and premium video content to easily reach larger audiences on today’s most popular digital devices, such as tablets and mobile phones.

You are designing an Azure web application.
All users must authenticate by using Active Directory Domain Services (AD DS) credentials.
You need to recommend an approach to enable single sign-on to the application for domain-authenticated users.
Which two actions should you recommend? Each correct answer presents part of the solution.
Use Forms authentication to generate claims.
Use the SQL membership provider in the web application.
Use Windows Identity Foundation in the web application.
Use Active Directory Federation Services (AD FS) to generate claims.

You are designing the deployment for Linux virtual machines (VMs) in Azure. The VMs will be used for a web app that will run in Azure.
The web app must be able to run Bash scripts on demand. Parallel workloads must also be set to scale automatically based on use.
You need to design the environment for the Bash scripts and parallel workloads.
Which processing type should you use for each component? To answer, drag the appropriate processing types to the correct components. Each processing type 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. NOTE: Each correct selection is worth one point.

You are the Azure architect for an organization. You are working with C-level management
to assign Azure role-based access control roles to a team within the organization. A single director oversees two teams, a development team and a test team. The director is wholly responsible for the organization#39;s Azure account, including billing, infrastructure, and access control. The director is the only member of the team with the ability to alter access controls.
You have the following requirements:
->Members of the development team must be able to view or alter Azure infrastructure to support application development.
->Members of the test team must be able to view Azure infrastructure to support test
You need to assign built-in Azure role-based access control roles to team members within the organization.
Which role should you assign to each team member? To answer, drag the appropriate role to the correct team member. Each role 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.

You have several virtual machines (VMs) that run in Azure. You also have a single System Center 2012 R2 Configuration Manager (SCCM) primary site on-premises.
You have the following requirements:
->All VMs must run on the same virtual network.
->Network traffic must be minimized between the on-premises datacenter and Azure.
->The solution minimize complexity.
You need to use SCCM to collect inventory and deploy software to Azure VMs. What should you do first?
Configure client push for the Azure virtual network.
Enable and configure Operations Insights in Azure.
Install a cloud distribution point on an Azure VM.
Install a secondary site underneath the primary site onto an Azure VM.
Explanation: Cloud-based distribution Point, a Configuration Manager Site System Role in the Cloud
Much of the Configuration Manager topology is made up of distribution points, they are very helpful in many situations where bandwidth and geographical separation are the facts of life, but also hard to manage if you have hundreds or even thousands of them.
This feature started with the vision that it makes perfect sense to have big distribution points in the Windows Azure cloud where one should not worry about things like (but not limited to) size, performance, reliability, security, access from all around the world, hardware/software update issues etc.
Note: Content management in System Center 2012 Configuration Manager provides the tools for you to manage content files for applications, packages, software updates, and operating system deployment. Configuration Manager uses distribution points to store files that are required for software to run on client computers. These distribution points function as distribution centers for the content files and let users download and run the software.
Clients must have access to at least one distribution point from which they can download the files.

You have the following requirements:
->The application must remain operational during batch-processing operations.
->Users must be able to roll back each image to a previous version.
You need to ensure that each remote application has exclusive access to an image while the application processes the image. Which type of storage should you use to store the images?

Explanation: * Blob Leases allow you to claim ownership to a Blob. Once you have the lease you can then update the Blob or delete the Blob without worrying about another process changing it underneath you. When a Blob is leased, other processes can still read it, but any attempt to update it will fail. You can update Blobs without taking a lease first, but you do run the chance of another process also attempting to modify it at the same time.
You can opt to use either optimistic or pessimistic concurrency models to manage access to blobs and containers in the blob service.
