Testlet 1 VanArsdel, Ltd 
Overview 
VanArsdel, Ltd. builds skyscrapers, subways, and bridges. VanArsdel is a leader in using technology to do construction better. 
Overview 
VanArsdel employees are able to use their own mobile devices for work activities because the company recognizes that this usage enables employee productivity. Employees also access Software as a Service (SaaS) applications, including DocuSign, Dropbox, and Citrix. The company continues to evaluate and adopt more SaaS applications for its business. VanArsdel uses Azure Active Directory (AD) to authenticate its employees, as well as Multi-Factor Authentication (MFA). Management enjoys the ease with which MFA can be enabled and disabled for employees who use cloud-based services. VanArsdel's on-premises directory contains a single forest. 
Helpdesk: 
VanArsdel creates a helpdesk group to assist its employees. The company sends email messages to all its employees about the helpdesk group and how to contact it. Configuring employee access for SaaS applications is often a time-consuming task. It is not always obvious to the helpdesk group which users should be given access to which SaaS applications. The helpdesk group must respond to many phone calls and email messages to solve this problem, which takes up valuable time. The helpdesk group is unable to meet the needs of VanArsdel's employees. However, many employees do not work with the helpdesk group to solve their access problems. Instead, these employees contact their co-workers or managers to find someone who can help them. Also, new employees are not always told to contact the helpdesk group for access problems. Some employees report that they cannot see all the applications in the Access Panel that they have access to. Some employees report that they must re-enter their passwords when they access cloud applications, even though they have already authenticated. 
Bring your own device (BYOD): 
VanArsdel wants to continue to support users and their mobile and personal devices, but the company is concerned about how to protect corporate assets that are stored on these devices. The company does not have a strategy to ensure that its data is removed from the devices when employees leave the company. 
Customer Support: 
VanArsdel wants a mobile app for customer profile registration and feedback. The company would like to keep track of all its previous, current, and future customers worldwide. A profile system using third-party authentication is required as well as feedback and support sections for the mobile app. 
Migration: 
VanArsdel plans to migrate several virtual machine (VM) workloads into Azure. They also plan to extend their on-premises Active Directory into Azure for mobile app authentication. 
Business Requirements 
Hybrid Solution: 
A single account and credentials for both on-premises and cloud applications Certain applications that are hosted both in Azure and on-site must be accessible to both VanArsdel employees and partners. The service level agreement (SLA) for the solution requires an uptime of 99.9% The partners all use Hotmail.com email addresses. 
Mobile App: 
VanArsdel requires a mobile app for project managers on construction job sites. The mobile app has the following requirements: 
The app must display partner information.
The app must alert project managers when changes to the partner information occur.
The app must display project information including an image gallery to view pictures of construction projects.
Project managers must be able to access the information remotely and securely. 
Security: 
VanArsdel must control access to its resources to ensure sensitive services and information are accessible 
    
only by authorized users and/or managed devices. Employees must be able to securely share data, based on corporate policies, with other VanArsdel employees and with partners who are located on construction job sites. VanArsdel management does NOT want to create and manage user accounts for partners. 
Technical Requirements 
Architecture: 
VanArsdel requires a non-centralized stateless architecture fonts data and services where application, data, and computing power are at the logical extremes of the network. VanArsdel requires separation of CPU storage and SQL services 
Data Storage: 
VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently, data transfer rates are excessive, and queue length for read/write operations affects performance. A mobile service that is used to access contractor information must have automatically scalable, structured storage Images must be stored in an automatically scalable, unstructured form. 
Mobile Apps: 
VanArsdel mobile app must authenticate employees to the company's Active Directory. Event-triggered alerts must be pushed to mobile apps by using a custom Node.js script. The customer support app should use an identity provider that is configured by using the Access Control Service for current profile registration and authentication. The customer support team will adopt future identity providers that are configured through Access Control Service. 
Security: 
Active Directory Federated Server (AD FS) will be used to extend AD into Azure. Helpdesk administrators must have access to only the groups of Azure resources they are responsible for. Azure administration will be performed by a separate group. IT administrative overhead must be minimized. Permissions must be assigned by using Role Based Access Control (RBAC). Line of business applications must be accessed securely. 
QUESTION 1 
You need to recommend a solution that allows partners to authenticate. Which solution should you recommend? 
A.	Configure the federation provider to trust social identity providers. 

B.	Configure the federation provider to use the Azure Access Control service. 

C.	Create a new directory in Azure Active Directory and create a user account for the partner. 

D.	Create an account on the VanArsdel domain for the partner and send an email message that contains the password to the partner. 

Correct Answer: B Explanation 
Explanation/Reference: 
* Scenario: The partners all use Hotmail.com email addresses.
* In Microsoft Azure Active Directory Access Control (also known as Access Control Service or ACS), an identity provider is a service that authenticates user or client identities and issues security tokens that ACS consumes.
The ACS Management Portal provides built-in support for configuring Windows Live ID as an ACS Identity Provider.
Incorrect:
Not C, not D: Scenario: VanArsdel management does NOT want to create and manage user accounts for partners.

QUESTION 2 
You are designing a plan to deploy a new application to Azure. The solution must provide a single sign-on experience for users. You need to recommend an authentication type. Which authentication type should you recommend? 
A. SAML credential tokens 
B. Azure managed access keys C. Windows Authentication
D. MS-CHAP 
Correct Answer: A Explanation 
Explanation/Reference: 
A Microsoft cloud service administrator who wants to provide their Azure Active Directory (AD) users with sign-on validation can use a SAML 2.0 compliant SP-Lite profile based Identity Provider as their preferred Security Token Service (STS) / identity provider. This is useful where the solution implementer already has a user directory and password store on-premises that can be accessed using SAML 2.0. This existing user directory can be used for sign-on to Office 365 and other Azure AD-secured resources.

QUESTION 3 
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 
Correct Answer: C Explanation 
Explanation/Reference: 
* 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. : Azure Queues and Service Bus Queues - Compared and Contrasted

QUESTION 4 
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). 

Correct Answer: D Explanation 
Explanation/Reference: 
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.
Reference: http://en.wikipedia.org/wiki/Single_sign-on 
QUESTION 5 
You need to assign permissions for the Virtual Machine workloads that you migrate to Azure. The solution must use the principal of least privileges. What should you do? 
A.	Create all VMs in the cloud service named Groupl and then connect to the Azure subscription. Run the following Windows PowerShell command: New-AzureRoleAssignment -Mail [email protected] - RoleDefinitionName Contributor -ResourceGroupName group1 

B.	In the Azure portal, select an individual virtual machine and add an owner. 

C.	In the Azure portal, assign read permission to the user at the subscription level. 

D.	Create each VM in a separate cloud service and then connect to the Azure subscription. Run the following Windows PowerShell command:
Get-AzureVM | New-AzureRoleAssignment -Mail [email protected] - RoleDefinitionName Contributor 

Correct Answer: A Explanation 
Explanation/Reference: 
* Scenario: Permissions must be assigned by using Role Based Access Control (RBAC).
* Role-Based access control (RBAC) in the Azure Portal and Azure Resource Management API allows you to manage access to your subscription at a fine-grained level. With this feature, you can grant access for Active Directory users, groups, or service principals by assigning some roles to them at a particular scope. Create a role assignment
Use New-AzureRoleAssignment to create a role assignment.
Example: This will create a role assignment for a group at a resource group level. PS C:\> New- AzureRoleAssignment -ObjectID  -RoleDefinitionName Reader - ResourceGroupName group1

Testlet 1
Trey Research 
Overview 
Trey Research conducts agricultural research and sells the results to the agriculture and food industries. The company uses a combination of on-premises and third-party server clusters to meet its storage needs. Trey Research has seasonal demands on its services, with up to 50 percent drops in data capacity and bandwidth demand during low-demand periods. They plan to host their websites in an agile, cloud environment where the company can deploy and remove its websites based on its business requirements rather than the requirements of the hosting company. A recent fire near the datacenter that Trey Research uses raises the management team's awareness of the vulnerability of hosting all of the company's websites and data at any single location. The management team is concerned about protecting its data from loss as a result of a disaster. 
Websites 
Trey Research has a portfolio of 300 websites and associated background processes that are currently hosted in a third-party datacenter. All of the websites are written in ASP.NET, and the background processes use Windows Services. The hosting environment costs Trey Research approximately S25 million in hosting and maintenance fees. 
Infrastructure 
Trey Research also has on-premises servers that run VMs to support line-of-business applications. The company wants to migrate the line-of-business applications to the cloud, one application at a time. The company is migrating most of its production VMs from an aging VMWare ESXi farm to a Hyper-V cluster that runs on Windows Server 2012. 
Applications 
DistributionTracking 
Trey Research has a web application named Distributiontracking. This application constantly collects realtime data that tracks worldwide distribution points to customer retail sites. This data is available to customers at all times. The company wants to ensure that the distribution tracking data is stored at a location that is geographically close to the customers who will be using the information. The system must continue running in the event of VM failures without corrupting data. The system is processor intensive and should be run in a multithreading environment. 
HRApp 
The company has a human resources (HR) application named HRApp that stores data in an on-premises SQL Server database. The database must have at least two copies, but data to support backups and business continuity must stay in Trey Research locations only. The data must remain on-premises and cannot be stored in the cloud. HRApp was written by a third party, and the code cannot be modified. The human resources data is used by all business offices, and each office requires access to the entire database. Users report that HRApp takes all night to generate the required payroll reports, and they would like to reduce this time. 
MetricsTracking 
Trey Research has an application named MetricsTracking that is used to track analytics for the DistributionTracking web application. The data MetricsTracking collects is not customer-facing. Data is stored on an on-premises SQL Server database, but this data should be moved to the cloud. Employees at other locations access this data by using a remote desktop connection to connect to the application, but latency issues degrade the functionality. Trey Research wants a solution that allows remote employees to access metrics data without using a remote desktop connection. MetricsTracking was written in-house, and the development team is available to make modifications to the application if necessary. However, the company wants to continue to use SQL Server for MetricsTracking. 
Business Requirements 
Business Continuity 
You have the following requirements:
Move all customer-facing data to the cloud.
Web servers should be backed up to geographically separate locations, If one website becomes unavailable, customers should automatically be routed to websites that are still operational. Data must be available regardless of the operational status of any particular website. 
   
The HRApp system must remain on-premises and must be backed up.
The MetricsTracking data must be replicated so that it is locally available to all Trey Research offices. 
Auditing and Security 
You have the following requirements:
Both internal and external consumers should be able to access research results.
Internal users should be able to access data by using their existing company credentials without requiring multiple logins.
Consumers should be able to access the service by using their Microsoft credentials.
Applications written to access the data must be authenticated. Access and activity must be monitored and audited.
Ensure the security and integrity of the data collected from the worldwide distribution points for the distribution tracking application. 
Storage and Processing 
You have the following requirements:
Provide real-time analysis of distribution tracking data by geographic location.
Collect and store large datasets in real-time data for customer use.
Locate the distribution tracking data as close to the central office as possible to improve bandwidth. Co-locate the distribution tracking data as close to the customer as possible based on the customer's location.
Distribution tracking data must be stored in the JSON format and indexed by metadata that is stored in a SQL Server database.
Data in the cloud must be stored in geographically separate locations, but kept with the same political boundaries. 
Technical Requirements 
Migration 
You have the following requirements:
Deploy all websites to Azure.
Replace on-premises and third-party physical server clusters with cloud-based solutions. Optimize the speed for retrieving exiting JSON objects that contain the distribution tracking data. Recommend strategies for partitioning data for load balancing. 
Auditing and Security 
You have the following requirements:
Use Active Directory for internal and external authentication. Use OAuth for application authentication. 
Business Continuity 
You have the following requirements:
Data must be backed up to separate geographic locations.
Web servers must run concurrent versions of all websites in distinct geographic locations. Use Azure to back up the on-premises MetricsTracking data.
Use Azure virtual machines as a recovery platform for MetricsTracking and HRApp.
Ensure that there is at least one additional on-premises recovery environment for the HRApp. 
QUESTION 1 
You need to configure the distribution tracking application. What should you do? 
A. Map each role to a single upgrade domain to optimize resource utilization. B. Design all services as stateless services.
C. Configure operations to queue when a role reaches its capacity.
D. Configure multiple worker roles to run on each virtual machine.
