Azure Monitor can collect data directly from your Azure virtual machines into a Log Analytics workspace for analysis of details and correlations. Installing the Log Analytics VM extension for Windows and Linux allows Azure Monitor to collect data from your Azure VMs.

Azure Log Analytics workspace is also used for on-premises computers monitored by System Center Operations Manager.

• The average CPU percentage is calculated 24 times per day. This is because the exhibit shows the CPU percentage for ASP1 in a 24-hour period, with one data point for each hour. Therefore, the average CPU percentage is calculated once per hour, or 24 times per day1.
• ASP1 must be scaled out to optimize CPU usage. This is because the exhibit shows that the CPU percentage for ASP1 is consistently above 80%, which indicates that the app service plan is under high load and needs more instances to handle the traffic. Scaling out means adding more instances to an app service plan, which can improve the performance and availability of the apps hosted on it2. Scaling up means changing the pricing tier of an app service plan, which can increase the resources available for each instance, but not necessarily reduce the CPU usage3.

• User1: You should assign the Reader and Data Access role to User1. This role grants read access to Azure resources and data, including the data in any storage account1. This role is suitable for User1’s task of viewing the data in any storage account, and it follows the principle of least privilege by not granting any write or delete permissions.
• User2: You should assign the Storage Account Contributor role to User2. This role grants full access to manage storage accounts and their data, including the ability to assign roles in Azure RBAC2. This role is suitable for User2’s task of assigning users the Contributor role for storage accounts, and it follows the principle of least privilege by not granting access to other types of resources.

The Owner role is a very high-level role that grants full access to manage all resources in the scope, including the ability to assign roles to other users. This role does not follow the principle of least privilege, which means that you should only grant the minimum level of access required to accomplish the goal.

To enable Traffic Analytics for an Azure subscription, you need to have a role that grants you the following permissions at the subscription level:

• Microsoft.Network/applicationGateways/read
• Microsoft.Network/connections/read
• Microsoft.Network/loadBalancers/read
• Microsoft.Network/localNetworkGateways/read
• Microsoft.Network/networkInterfaces/read
• Microsoft.Network/networkSecurityGroups/read
• Microsoft.Network/publicIPAddresses/read
• Microsoft.Network/routeTables/read
• Microsoft.Network/virtualNetworkGateways/read
• Microsoft.Network/virtualNetworks/read
• Microsoft.OperationalInsights/workspaces/*

Some of the built-in roles that have these permissions are Owner, Contributor, or Network Contributor1. However, these roles also grant other permissions that may not be necessary or desirable for enabling Traffic Analytics. Therefore, the best practice is to use the principle of least privilege and create a custom role that only has the required permissions for enabling Traffic Analytics2.

Therefore, to meet the goal of ensuring that an Azure AD user named Admin1 is assigned the required role to enable Traffic Analytics for an Azure subscription, you should create a custom role with the required permissions and assign it to Admin1 at the subscription level.

Moving the virtual machine to a different subscription does not change the host that the virtual machine runs on. It only changes the billing and management of the resources. To move the virtual machine to a different host, you need to redeploy it or use Azure Site Recovery. Then, References: [Move resources to new resource group or subscription] [Redeploy Windows VM to new Azure node] [Use Azure Site Recovery to migrate Azure VMs between Azure regions]

Based on the file named Deploy.json and the cmdlet you ran, here are the answers to your statements:

• You can deploy a virtual machine to RGI. = No
• You can deploy a virtual machine to RG2. = No
• You can manually create a resource group named RG3. = Yes

Let me explain why:

• The Deploy.json file defines a template for creating a resource group and a virtual machine in Azure. The template has two parameters: resourceGroupName and vmName. The template also has two resources: one for the resource group and one for the virtual machine. The resource group resource has a property called name, which is set to the value of the resourceGroupName parameter. The virtual machine resource has a property called location, which is set to the value of the location parameter of the deployment cmdlet.
• The cmdlet you ran specifies the location as westus and the template file as Deploy.json. However, it does not specify any values for the resourceGroupName and vmName parameters. Therefore, the cmdlet will prompt you to enter those values interactively before creating the deployment.
• If you enter RGI as the value for the resourceGroupName parameter and VM1 as the value for the vmName parameter, then the cmdlet will create a resource group named RGI and a virtual machine named VM1 in the westus location. Therefore, you can deploy a virtual machine to RGI.
• However, if you enter RG2 as the value for the resourceGroupName parameter, then the cmdlet will fail with an error. This is because RG2 already exists in your subscription and you cannot create a resource group with the same name as an existing one. Therefore, you cannot deploy a virtual machine to RG2 using this template and cmdlet.
• You can manually create a resource group named RG3 by using another cmdlet: New-AzResourceGroup. This cmdlet takes two parameters: Name and Location. For example, you can run the following cmdlet to create a resource group named RG3 in westus:

New-AzResourceGroup -Name RG3 -Location westus

Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com.

The initial domain name cannot be changed or deleted, but you can add your corporate domain name to Azure AD as well. For example, your organization probably has other domain names used to do business and users who sign in using your corporate domain name. Adding custom domain names to Azure AD allows you to assign user names in the directory that are familiar to your users, such as ‘alice@contoso.com.’ instead of 'alice@domain name.onmicrosoft.com'.

Scenario:

Network Infrastructure: Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.

Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com

Planned Azure AD Infrastructure: The on-premises Active Directory domain will be synchronized to Azure AD.

Technically, The finance department needs to migrate their users from AD to AAD using AADC based on the finance OU, and need to enforce MFA use. This is conditional access policy. Employees also often get promotions and/or join other departments and when that occurs, the user's OU attribute will change when the admin puts the user in a new OU, and the dynamic group conditional access exception (OU= [Department Name Value]) will move the user to the appropriate dynamic group on next AADC delta sync.

https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-9.3.0#-resourcegroupname

Specifies the name of the resource group to deploy.

https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-9.3.0#-mode

Specifies the deployment mode. The acceptable values for this parameter are:

-Complete: In complete mode, Resource Manager deletes resources that exist in the resource group but are not specified in the template.

- Incremental: In incremental mode, Resource Manager leaves unchanged resources that exist in the resource group but are not specified in the template.

The New-MgUser cmdlet is part of the Microsoft Graph PowerShell SDK, which is a module that allows you to interact with the Microsoft Graph API. The Microsoft Graph API is a service that provides access to data and insights across Microsoft 365, such as users, groups, mail, calendar, contacts, files, and more1.

The New-MgUser cmdlet can be used to create new users in your Azure AD tenant, but it has some limitations and requirements. For example, you need to have the Global Administrator or User Administrator role in your tenant, you need to authenticate with the Microsoft Graph API using a certificate or a client secret, and you need to specify the required parameters for the new user, such as userPrincipalName, accountEnabled, displayName, mailNickname, and passwordProfile2.

However, the New-MgUser cmdlet does not support creating guest user accounts in your Azure AD tenant. Guest user accounts are accounts that belong to external users from other organizations or domains. Guest user accounts have limited access and permissions in your tenant, and they are typically used for collaboration or sharing purposes3.

To create guest user accounts in your Azure AD tenant, you need to use a different cmdlet: New-AzureADMSInvitation. This cmdlet is part of the Azure AD PowerShell module, which is a module that allows you to manage your Azure AD resources and objects. The New-AzureADMSInvitation cmdlet can be used to create and send an invitation email to an external user, which contains a link to join your Azure AD tenant as a guest user. You can also specify some optional parameters for the invitation, such as the invited user display name, message info, redirect URL, or send invitation message.

Therefore, to meet the goal of creating guest user accounts for 500 external users from a CSV file, you need to use a PowerShell script that runs the New-AzureADMSInvitation cmdlet for each user, not the New-MgUser cmdlet.

Redeploying the virtual machine moves it to a new host within the same region and availability set. This can help resolve any underlying issues with the current host. Redeploying the virtual machine does not affect the configuration or data on the virtual machine. Then, References: [Redeploy Windows VM to new Azure node]

Statement 1: Yes

All client computers in the Paris office will be joined to an Azure AD domain.

A virtual network named Paris-VNet that will contain two subnets named Subnet1 and Subnet2.

Microsoft Windows Server Active Directory domains, can resolve DNS names between virtual networks. Automatic registration of virtual machines from a virtual network that's linked to a private zone with auto-registration enabled. Forward DNS resolution is supported across virtual networks that are linked to the private zone.

Statement 2: Yes

A virtual network named ClientResources-VNet that will contain one subnet named ClientSubnet You plan to create a private DNS zone named humongousinsurance.local and set the registration network to the ClientResources-VNet virtual network.

As this is a registration network so this will work.

Statement 3: No

Only VMs in the registration network, here the ClientResources-VNet, will be able to register hostname records. Since Subnet4 not connected to Client Resources Network thus not able to register its hostname with humongoinsurance.local

D: Seamless SSO works with any method of cloud authentication - Password Hash Synchronization or Pass-through Authentication, and can be enabled via Azure AD Connect.

B: You can gradually roll out Seamless SSO to your users. You start by adding the following Azure AD URL to all or selected users' Intranet zone settings by using Group Policy in Active Directory: https://autologon.microsoftazuread-sso.com

IdFix is used to perform discovery and remediation of identity objects and their attributes in an on-premises Active Directory environment in preparation for migration to Azure Active Directory. IdFix is intended for the Active Directory administrators responsible for directory synchronization with Azure Active Directory.

Scenario: Active Directory Issue

Several users in humongousinsurance.com have UPNs that contain special characters.

You suspect that some of the characters are unsupported in Azure AD.

Scenario: Licensing Issue

1. You attempt to assign a license in Azure to several users and receive the following error message: "Licenses not assigned. License agreement failed for one user."

2. You verify that the Azure subscription has the available licenses.

Solution:

License cannot be assigned to a user without a usage location specified.

Some Microsoft services aren't available in all locations because of local laws and regulations. Before you can assign a license to a user, you must specify the Usage location property for the user. You can specify the location under the User > Profile > Settings section in the Azure portal.

Once the VNets are peered, all resources on one VNet can communicate with resources on the other peered VNets. You plan to enable peering between Paris-VNet and AllOffices-VNet. Therefore VMs on Subnet1, which is on Paris-VNet and VMs on Subnet3, which is on AllOffices-VNet will be able to connect to each other.

All Azure resources connected to a VNet have outbound connectivity to the Internet by default. Therefore VMs on ClientSubnet, which is on ClientResources-VNet will have access to the Internet; and VMs on Subnet3 and Subnet4, which are on AllOffices-VNet will have access to the Internet.

Cost analysis: Correct Option

In cost analysis blade of Azure, you can see all the detail for custom time span. You can use this to determine expenditure of last few day, weeks, and month. Below options are available in Cost analysis blade for filtering information by time span:  last 7 days, last 30 days, and custom date range. Choosing the first option (last 7 days) auditors can view the costs by time span.

Cost analysis shows data for the current month by default. Use the date selector to switch to common date ranges quickly. Examples include the last seven days, the last month, the current year, or a custom date range. Pay-as-you-go subscriptions also include date ranges based on your billing period, which isn't bound to the calendar month, like the current billing period or last invoice. Use the <PREVIOUS and NEXT> links at the top of the menu to jump to the previous or next period, respectively. For example, <PREVIOUS will switch from the Last 7 days to 8-14 days ago or 15-21 days ago.

Invoice: Incorrect Option

Invoices can only be used for past billing periods not for current billing period, i.e. if your requirement is to know the last week's cost then that also not filled by invoices because Azure  generates invoice at the end of the month. Even though Invoices have custom timespan, but when you put in dates for a week, the pane would be empty. Below is from Microsoft document:

Resource Provider: Incorrect Option

When deploying resources, you frequently need to retrieve information about the resource providers and types. For example, if you want to store keys and secrets, you work with the Microsoft.KeyVault resource provider. This resource provider offers a resource type called vaults for creating the key vault. This is not useful for reviewing all Azure costs from the past week which is required for audit.

Payment method: Incorrect Option

Payment methods is not useful for reviewing all Azure costs from the past week which is required for audit.

Azure Storage Explorer is a free tool from Microsoft that allows you to work with Azure Storage data on Windows, macOS, and Linux. You can use it to upload and download data from Azure blob storage.

Scenario:

Planned Changes include: move the existing product blueprint files to Azure Blob storage.

Technical Requirements include: Copy the blueprint files to Azure over the Internet.

References: https://docs.microsoft.com/en-us/azure/machine-learning/team-data-science-process/move-data-to-azure-blob-using-azure-storage-explorer

Statement 1: Yes

Contoso is moving the existing product blueprint files to Azure Blob storage which will ensure that the blueprint files are stored in the archive storage tier.

Use unmanaged standard storage for the hard disks of the virtual machines. We use Page Blobs for these.

Statement 2: No

Azure Table storage stores large amounts of structured data. The service is a NoSQL datastore which accepts authenticated calls from inside and outside the Azure cloud. Azure tables are ideal for storing structured, non-relational data. Common uses of Table storage include:

1. Storing TBs of structured data capable of serving web scale applications

2. Storing datasets that don't require complex joins, foreign keys, or stored procedures and can be denormalized for fast access

3. Quickly querying data using a clustered index

4. Accessing data using the OData protocol and LINQ queries with WCF Data Service .NET Libraries

Statement 3: No

File Storage can be used if your business use case needs to deal mostly with standard File extensions like *.docx, *.png and *.bak then you should probably go with this storage option.

A Recovery Services vault is a logical container that stores the backup data for each protected resource, such as Azure VMs. When the backup job for a protected resource runs, it creates a recovery point inside the Recovery Services vault.

Scenario:

There are three application tiers, each with five virtual machines.

Move all the virtual machines for App1 to Azure.

Ensure that all the virtual machines for App1 are protected by backups.
