Implementing Microsoft Azure Infrastructure Solutions
Question No: 111
You administer a virtual machine (VM) that is deployed to Azure. You configure a rule to generate an alert when the average availability of a web service on your VM drops below 95 percent for 15 minutes.
The development team schedules a one-hour maintenance period. You have the following requirements:
-> No alerts are created during the maintenance period.
-> Alerts can be restored when the maintenance is complete.
You want to achieve this goal by using the least amount of administrative effort. What should you do from the Management Portal?
Select and disable the rule from the Dashboard page of the virtual machine.
Select and delete the rule from the Configure page of the virtual machine.
Select and disable the rule from the Monitor page of the virtual machine.
Select and disable the rule on the Configure page of the virtual machine.
Answer: C Explanation:
You can configure virtual machine alert rules on:

Note: This question is part of a series of questions that present the same scenario. Each questions in the series contains a unique solution that might meet the stated goals. Some questions sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review scree.
You create an Ubuntu Linux virtual machine (VM) by using the Azure Portal. You do not specify a password when you create the VM.
You need to connect to the terminal of the VM.
Solution: You connect to the public IP address of the VM by using Secure Shell (SSH) and specify your public key.
Does the solution meet the goal?

Question No: 113
You have an existing classic virtual network.
You need to export the virtual network settings to an XML file to make modifications. Which Azure PowerShell cmdlet should you use?
Question No: 114 DRAG DROP
You plan to deploy a cloud service named contosoapp that has a web role named contosoweb and a worker role named contosoimagepurge.
You need to ensure the service meets the following requirements:
-> Contosoweb can be accessed over the Internet by using http.
-> Contosoimagepurge can only be accessed through tcp port 5001 from contosoweb.
-> Contosoimagepurge cannot be accessed directly over the Internet.
Which configuration should you use? To answer, drag the appropriate configuration setting to the correct location in the service configuration file. Each configuration setting 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 publish an application named MyApp to Azure Active Directory (Azure AD). You grant access to the web APIs through OAuth 2.0.
MyApp is generating numerous user consent prompts. You need to reduce the amount of user consent prompts. What should you do?
Enable Multi-resource refresh tokens.
Enable WS-federation access tokens.
Configure the Open Web Interface for .NET.
Configure SAML 2.0.
Answer: A Explanation:
When using the Authorization Code Grant Flow, you can configure the client to call multiple
resources. Typically, this would require a call to the authorization endpoint for each target service. To avoid multiple calls and multiple user consent prompts, and reduce the number of refresh tokens the client needs to cache, Azure Active Directory (Azure AD) has implemented multi-resource refresh tokens. This feature allows you to use a single refresh token to request access tokens for multiple resources.

You are designing a Windows Azure application.
The application includes processes that communicate by using Windows Communications Foundation (WCF) services.
The WCF services must support streaming.
You need to recommend a host for the processes and a WCF binding.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)
Host the processes in web roles.
Host the processes in worker roles.
Use NetTcpBinding for the WCF services.
Use WSHttpBinding for the WCF services.
Question No: 117
You are planning an upgrade strategy for an existing Azure application. Multiple instances of the application run in Azure. The management team is concerned about application downtime, due to a business service level agreement (SLA).
You are evaluating which change in your environment will require downtime. You need to identify the changes to the environment that will force downtime. Which change always requires downtime?
Adding an HTTPS endpoint to a web role
Upgrading the hosted service by deploying a new package
Changing the value of a configuration setting
Changing the virtual machine size
Answer: A Explanation:
If you change the number of endpoints for your service, for example by adding a HTTPS endpoint for your existing Web Role, it will require downtime.

You plan to use Password Sync on your DirSync Server with Azure Active Directory (Azure AD) on your company network. You configure the DirSync server and complete an initial synchronization of the users.
Several remote users are unable to log in to Office 365. You discover multiple event log entries for quot;Event ID 611 Password synchronization failed for domain.quot;
You need to resolve the password synchronization issue.
Which two actions should you perform? Each correct answer presents part of the solution.
Restart Azure AD Sync Service.
Run the Set-FullPasswordSync Power Shell cmdlet.
Force a manual synchronization on the DirSync server.
Add the DirSync service account to the Schema Admins domain group.
Answer: A,B Explanation:
The Set-FullPasswordSync Power Shell cmdlet resets the password sync state information forcing a full sync the next time the service is restarted. Then we need to restart the service to initiate the sync.
Question No: 119 HOTSPOT
You need to view a live stream of log events for the web application.
How should you configure the Azure PowerShell command? To answer, select the appropriate Azure PowerShell segment from each list in the answer area.
Question No: 120
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?
Store images in Azure Blob service. Store references to the images in the queue.
Store images in the queue.
Store images in OneDrive attached to the worker role instances. Store references to the images in the queue.
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.
