Question No: 4

You are designing a Windows Azure application. The application includes two web roles and three instances of a worker role. The web roles will send requests to the worker role through one or more Windows Azure Queues. You have the following requirements:

-Ensure that each request is processed exactly one time.

-Minimize the idle time of each worker role instance.

-Maximize the reliability of request processing.

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.

You need to configure identity synchronization. What should you create?

A. a second Azure Active Directory Connect sync server

B. backups of all on-premises server farms

C. backups of all Azure VMs

D. a second Azure Active Directory Connect staging server

E. a second Azure Active Directory directory

Answer: D

Explanation:

/ High availability is required for account synchronization services.

/ Any configuration changes to account synchronization must be tested without disrupting the services.

What should you use?

A. Azure health probes

B. Azure Fabric Controller

C. Azure Load Balancer

D. Azure Traffic Manager

Answer: D

Question No: 7

You are designing a plan to migrate an existing application to Windows Azure. The application currently resides on a server that has 20 GB of hard disk space.

A. ExtraSmall

B. ExtraLarge

C. Small

D. Large

Answer: A

Explanation:

ExtraSmall provides the required 20 GB of hard disk space.

Question No: 8

You develop an ASP.NET Web API that is hosted as an Azure Web App. The API uses a WebJob to process information. The WebJob has a very long start up time.

You configure to WebJob to run continuously. You observe that the WebJob is not running and processing information as expected.

You need to ensure the WebJob runs continuously. What should you do?

A. Enable the Always On configuration setting for the Web App.

B. Update the API self-host by using the Open Web Interface for .NET (OWIN). Migrate the API to Azure Service Fabric.

C. Schedule the WebJob by using the Azure Scheduler.

D. Include a settings.job JSON file at the root of the WebJob zip file and include a valid CRON expression.

Answer: A

Question No: 9

You administer of a set of virtual machine (VM) guests hosted in Hyper-V on Windows

Server 2012 R2. The virtual machines run the following operating systems:

* Windows Server 2008

* Windows Server 2008 R2

* Linux (openSUSE 13.1)

All guests currently are provisioned with one or more network interfaces with static bindings and VHDX disks. You need to move the VMs to Azure Virtual Machines hosted in an Azure subscription. Which three actions should you perform?

Each correct answer presents part of the solution.

A. Install the WALinuxAgent on Linux servers.

B. Ensure that all servers can acquire an IP by means of Dynamic Host Configuration Protocol (DHCP).

C. Upgrade all Windows VMs to Windows Server 2008 R2 or higher.

D. Sysprep all Windows servers

E. Convert the existing virtual disks to the virtual hard disk (VHD) format.

Answer: A,B,E

Explanation:

The Azure Linux Agent is installed on the Linux VM and is responsible to communicate with the Azure Frabric Controller.

It is a prerequisite that the Virtual Machines can receive ip addresses from DHCP. Azure does not use VHDX, only VHD. We are required to convert VHDX to VHD.

Question No: 10

You are designing an Azure application that stores data. You have the following requirements:

* The data storage system must support storing more than 500 GB of data.

* Data retrieval must be possible from a large number of parallel threads.

* Threads must not block each other.

You need to recommend an approach for storing data. What should you recommend?

A. Azure Notification Hubs

B. A single SQL database in Azure

C. Azure Queue storage

D. Azure Table storage

Answer: D

Explanation:

* Azure Table Storage can be useful for applications that must store large amounts of nonrelational data, and need additional structure for that data. Tables offer key-based access to unschematized data at a low cost for applications with simplified data-access patterns. While Azure Table Storage stores structured data without schemas, it does not provide any way to represent relationships between the data.

* As a solution architect/developer, consider using Azure Table Storage when:

/ Your application stores and retrieves large data sets and does not have complex relationships that require server-side joins, secondary indexes, or complex server-side logic.

/ You need to achieve a high level of scaling without having to manually shard your dataset. References: https://msdn.microsoft.com/en-us/library/azure/jj553018.aspx

B. an on-premises solution

C. a Microsoft Office 365 subscription

D. the Enterprise Mobility Suite

Answer: A
