Question 41
You have an Azure web app.
You need to manage the settings of the web app from an iPhone.
What are two Azure management tools that you can use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Azure CLI
* B. the Azure portal
* C. Azure Cloud Shell
D. Windows PowerShell
E. Azure Storage Explorer
Explanation
The Azure portal is the web-based portal for managing Azure. Being web-based, you can use the Azure portal on an iPhone.
Azure Cloud Shell is a web-based command line for managing Azure. You access the Azure Cloud Shell from the Azure portal. Being web-based, you can use the Azure Cloud Shell on an iPhone.
Incorrect Answers:
A: Azure CLI can be installed on MacOS but it cannot be installed on an iPhone.
D: Windows PowerShell can be installed on MacOS but it cannot be installed on an iPhone.
E: Azure Storage Explorer is not used to manage Azure web apps.
Question 42
You have an application that is comprised of an Azure web app that has a Service Level Agreement (SLA) of 99.95 percent and an Azure SQL database that has an SLA of 99.99 percent.
The composite SLA for the application is [the product of both SLAs, which equals 99.94 percent.]
Instructions: Review the underlined text. If it makes the statement correct, select “No change is needed”. If the statement is incorrect, select the answer choice that makes the statement correct.
* A. No change is needed
B. the lowest SLA associated to the application, which is 99.95 percent
C. the highest SLA associated to the application, which is 99.99 percent
D. the difference between the two SLAs, which is 0.05 percent
Explanation
Composite SLAs involve multiple services supporting an application, each with differing levels of availability.
For example, consider an App Service web app that writes to Azure SQL Database. At the time of this writing, these Azure services have the following SLAs:
- App Service web apps = 99.95%
- SQL Database = 99.99%
What is the maximum downtime you would expect for this application? If either service fails, the whole application fails. The probability of each service failing is independent, so the composite SLA for this application is 99.95% × 99.99% = 99.94%. That’s lower than the individual SLAs, which isn’t surprising because an application that relies on multiple services has more potential failure points.
Question 43
Your company plans to deploy an Artificial Intelligence (AI) solution in Azure.
What should the company use to build, test, and deploy predictive analytics solutions?
A. Azure Logic Apps
* B. Azure Machine Learning Studio
C. Azure Batch
D. Azure Cosmos DB
Explanation
Microsoft Azure Machine Learning Studio (classic) is a collaborative, drag-and-drop tool you can use to build, test, and deploy predictive analytics solutions on your data. Azure Machine Learning Studio (classic) publishes models as web services that can easily be consumed by custom apps or BI tools such as Excel.

Machine Learning Studio is where data science, predictive analytics, cloud resources, and your data meet.
To develop a predictive analysis model, you typically use data from one or more sources, transform, and analyze that data through various data manipulation and statistical functions, and generate a set of results. Developing a model like this is an iterative process. As you modify the various functions and their parameters, your results converge until you are satisfied that you have a trained, effective model.
Question 44
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question 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 screen.
You have an Azure subscription named Subscription1.
You sign in to the Azure portal and create a resource group named RG1.
From Azure documentation, you have the following command that creates a virtual machine named VM1.
az vm create --resource-group RG1 --name VM1 --image UbuntuLTS --generate-sshkeys
You need to create VM1 in Subscription1 by using the command.
Solution: From the Azure portal, launch Azure Cloud Shell and select PowerShell. Run the command in Cloud Shell.
Does this meet the goal?
* A. Yes
B. No
Explanation
The command can be run in the Azure Cloud Shell. Although this question says you select PowerShell rather than Bash, the Az commands will work in PowerShell.
The Azure Cloud Shell is a free interactive shell. It has common Azure tools preinstalled and configured to use with your account.
To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com/bash.
Question 45
You have an Azure subscription named Subscription1.
You sign in to the Azure portal and create a resource group named RG1.
From Azure documentation, you have the following command that creates a virtual machine named VM1.
az vm create --resource-group RG1 --name VM1 --image UbuntuLTS --generate-ssh-keys
You need to create VM1 in Subscription1 by using the command.
Solution: From a computer that runs Windows 10, install Azure CLI. From PowerShell, sign in to Azure and then run the command.
Does this meet the goal?
A. Yes
* B. No
Explanation
The command can be run from PowerShell or the command prompt if you have the Azure CLI installed. However, it must be run on the Windows 10 computer, not in Azure.
Question 46
You have an Azure subscription named Subscription1.
You sign in to the Azure portal and create a resource group named RG1.
From Azure documentation, you have the following command that creates a virtual machine named VM1.
az vm create --resource-group RG1 --name VM1 --image UbuntuLTS --generate-ssh-keys
You need to create VM1 in Subscription1 by using the command.
Solution: From a computer that runs Windows 10, install Azure CLI. From a command prompt, sign in to Azure and then run the command.
Does this meet the goal?
A. Yes
* B. No
Explanation
The command can be run from PowerShell or the command prompt if you have the Azure CLI installed. However, it must be run on the Windows 10 computer, not in Azure.
Question 47
An Azure administrator plans to run a PowerShell script that creates Azure resources.
You need to recommend which computer configuration to use to run the script.
Solution: Run the script from a computer that runs Windows 10 and has the Azure PowerShell module installed.
Does this meet the goal?
* A. Yes
B. No
Explanation
A PowerShell script is a file that contains PowerShell cmdlets and code. A PowerShell script needs to be run in PowerShell.
In this question, the computer has the Azure PowerShell module installed. Therefore, this solution does meet the goal.

Question 50
Your company has several business units.
Each business unit requires 20 different Azure resources for daily operation.
All the business units require the same type of Azure resources.
You need to recommend a solution to automate the creation of the Azure resources.
What should you include in the recommendations?
* A. Azure Resource Manager templates
B. virtual machine scale sets
C. the Azure API Management service
D. management groups
Explanation
You can use Azure Resource Manager templates to automate the creation of the Azure resources.
Deploying resource through templates is known as ‘Infrastructure as code’.
To implement infrastructure as code for your Azure solutions, use Azure Resource Manager templates. The template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax, which lets you state what you intend to deploy without having to write the sequence of programming commands to create it. In the template, you specify the resources to deploy and the properties for those resources.
Azure Resource Manager Template defines the resources you need to deploy for your solution. First of all, you must know that an Azure Resource Manager Template is a just a simple JSON file. JSON is an open-standard file format derived from JavaScript. Note that a JSON file is a collection of name/value pairs.
