Q17. - (Topic 1)
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 user1@vanarsdelltd.com -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 userl@vanarsdelltd.com - RoleDefinitionName Contributor
Answer: A
Explanation: * 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 <group object ID> -RoleDefinitionName Reader -ResourceGroupName group1

Q18. - (Topic 6)
You are designing an Azure web application. The solution will be used by multiple customers. Each customer has different business logic and user interface requirements. Not all customers use the same version of the .NET runtime.
You need to recommend a deployment strategy. What should you recommend?
A. Deploy with multiple web role instances.
B. Deploy each application in a separate tenant.
C. Deploy all applications in one tenant.
D. Deploy with multiple worker role instances.
Answer: B
Explanation: There are two types of tenant environments. The simplest type is a single- tenant application where one customer has 100% dedicated access to an application’s process space. A single Tenant Applications has a separate, logical instance of the application for each customer or client. A single tenant application is much more predictable and stable by its nature since there will never be more than one dedicated customer at any point in time in that VM. That customer has all of its users accessing that dedicated instance of the application.

Q19. - (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.

Q20. - (Topic 6)
You are designing an Azure application. The application includes services hosted in
different geographic locations. The service locations may change. You must minimize the cost of communication between services.
You need to recommend an approach for data transmission between your application and Azure services. The solution must minimize administrative effort.
What should you recommend?
A. Azure Table storage
B. Service Bus queue
C. Service Management API
D. Azure Queue storage
Answer: B
Explanation: The cost of ACS transactions is insignificant when performing messaging operations against Service Bus queues. Service Bus acquires one ACS token per a single instance of the messaging factory object. The token is then reused until it expires, after about 20 minutes. Therefore, the volume of messaging operations in Service Bus is not directly proportional to the amount of ACS transactions required to support these operations.

Q21. - (Topic 6)

D. Azure Traffic Manager
Answer: D
Q22. - (Topic 6)

A. Migrate the Web App to Azure Service Fabric.
B. Implement an Azure Redis Cache.
C. Enable the Always On feature of the Web App.
D. Create a services layer by using an Azure-hosted ASP.NET web API.
E. Use an Azure Content Delivery Network (CDN).
Answer: A
Q23. - (Topic 7)

Q24. - (Topic 3)
You need to recommend a solution for publishing one of the company websites to Azure and configuring it for remote debugging.
Which two actions should you perform? Each correct answer presents part of the solution.
A. From Visual Studio, attach the debugger to the solution.
B. Set the application logging level to Verbose and enable logging.
C. Set the Web Server logging level to Information and enable logging.
D. Set the Web Server logging level to Verbose and enable logging.
E. From Visual Studio, configure the site to enable Debugger Attaching and then publish the site.
Answer: A,D
Explanation: * Scenario:
/ Mitigate the need to purchase additional tools for monitoring and debugging.
/A debugger must automatically attach to websites on a weekly basis. The scripts that handle the configuration and setup of debugging cannot work if there is a delay in attaching the debugger.
* A: After publishing your application you can use the Server Explorer in Visual Studio to access your web sites.
After signing in you will see your Web Sites under the Windows Azure node in Server Explorer. Right click on the site that you would like to debug and select Attach Debugger.
D: We need to debug the web site, not an application. We should use the more informative Verbose logging level.

Q27. - (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.

Q29. - (Topic 6)
A company hosts a website and exposes web services on the company intranet.
The intranet is secured by using a firewall. Company policies prohibit changes to firewall rules.
Devices outside the firewall must be able to access the web services. You need to recommend an approach to enable inbound communication. What should you recommend?
A. The Azure Access Control Service
B. Windows Azure Pack
C. The Azure Service Bus
D. A web service in an Azure role that relays data to the internal web services
Answer: C
Explanation: The Service Bus Relay is designed for the use-case of taking existing Windows Communication Foundation (WCF) web services and making those services securely accessible to solutions that reside outside the corporate perimeter without requiring intrusive changes to the corporate network infrastructure. Such Service Bus relay services are still hosted inside their existing environment, but they delegate listening for incoming sessions and requests to the cloud-hosted Service Bus.
