Q2. - (Topic 6)

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?

A. Configure client push for the Azure virtual network.

B. Enable and configure Operations Insights in Azure.

C. Install a cloud distribution point on an Azure VM.

D. Install a secondary site underneath the primary site onto an Azure VM.

Answer: C

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.

Q3. - (Topic 6)

You are designing an Azure development environment. Team members learn Azure development techniques by training in the development environment.

The development environment must auto scale and load balance additional virtual machine (VM) instances.

You need to recommend the most cost-effective compute-instance size that allows team members to work with Azure in the development environment.

What should you recommend?

A. Azure A1 standard VM Instance

B. Azure A2 basic VM Instance

C. Azure A3 basic VM Instance

D. Azure A9 standard VM Instance

Answer: A

Explanation: Azure A1 standard VM Instance would be cheapest with 1 CPU core, 0.75 GB RAM, and 40 GB HD. It would be good enough for training purposes.

Q4. DRAG DROP - (Topic 5)

You need to design the notification service for the customer-facing mobile app.

Which three actions 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:

Q5. - (Topic 6)

You design an Azure application that processes images. The maximum size of an image is 10 MB. The application includes a web role that allows users to upload images and a worker role with multiple instances that processes the images. The web role communicates with the worker role by using an Azure Queue service.

You need to recommend an approach for storing images that minimizes storage transactions.

What should you recommend?

A. Store images in Azure Blob service. Store references to the images in the queue.

B. Store images in the queue.

C. Store images in OneDrive attached to the worker role instances. Store references to the images in the queue.

D. Store images in local storage on the web role instance. Store references to the images in the queue.

Answer: A

Explanation: Azure Queues provide a uniform and consistent programming model across queues, tables, and BLOBs – both for developers and for operations teams. Microsoft Azure blob storage can be used to store the image data, the application can use a worker role in Azure to perform background processing tasks on the images, how the application may use shared access signatures to control access to the images by users. Azure blobs provide a series of containers aimed at storing text or binary data. Block blob containers are ideal for streaming data, while page blob containers can be used for random

read/write operations. Reference: 5 – Executing Background Tasks https://msdn.microsoft.com/en-gb/library/ff803365.aspx Reference: Azure Queues and Service Bus Queues - Compared and Contrasted https://msdn.microsoft.com/en-us/library/azure/hh767287.aspx

Q6. DRAG DROP - (Topic 6)

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'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 cases.

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.

Q7. HOTSPOT - (Topic 2)

You need to design a data storage strategy for each application.

In the table below, identify the strategy that you should use for each application. Make only one selection in each column.

Answer:

Q8. - (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?

A. 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.

B. Create a single queue. Send all requests on the single queue.

C. Create a queue for each worker role instance. Send requests on each worker queue by using a round robin rotation.

D. Create a queue for each web role. Send requests on all queues at the same time.

Answer: B

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.

Q9. - (Topic 1)

You need to design the system that alerts project managers to data changes in the contractor information app.

Which service should you use?

A. Azure Mobile Service

B. Azure Service Bus Message Queueing

C. Azure Queue Messaging

D. Azure Notification Hub

Answer: C

Explanation: * Scenario:

/ Mobile Apps: Event-triggered alerts must be pushed to mobile apps by using a custom

Node.js script.

/ The service level agreement (SLA) for the solution requires an uptime of 99.9%

* If you are already using Azure Storage Blobs or Tables and you start using queues, you are guaranteed 99.9% availability. If you use Blobs or Tables with Service Bus queues, you will have lower availability.

Note: Microsoft Azure supports two types of queue mechanisms: Azure Queues and Service Bus Queues. / Azure Queues, which are part of the Azure storage infrastructure, feature a simple REST-based Get/Put/Peek interface, providing reliable, persistent messaging within and between services. / Service Bus queues are part of a broader Azure messaging infrastructure that supports queuing as well as publish/subscribe, Web service remoting, and integration patterns.

Q10. - (Topic 1)

You need to ensure that users do not need to re-enter their passwords after they authenticate to cloud applications for the first time.

What should you do?

A. Enable Microsoft Account authentication.

B. Set up a virtual private network (VPN) connection between the VanArsdel premises and Azure datacenter. Set up a Windows Active Directory domain controller in Azure VM. Implement Integrated Windows authentication.

C. Deploy ExpressRoute.

D. Configure Azure Active Directory Sync to use single sign-on (SSO).

Answer: D

Explanation: Single sign-on (SSO) is a property of access control of multiple related, but independent software systems. With this property a user logs in once and gains access to all systems without being prompted to log in again at each of them.
