Microsoft AZ-104 Microsoft Azure Administrator Exam Practice Test

To create an inbound NAT rule, you need to specify a frontend IP address and a frontend port for the load balancer to receive the traffic, and a backend IP address and a backend port for the load balancer to forward the traffic to1. According to the first table, LB1 has only one frontend IP address, which is 40.121.183.105. However, this frontend IP address is already used by the existing inbound NAT rule named rule1, which forwards port 80 to VM1 on port 802. Therefore, you cannot use the same frontend IP address and port for another inbound NAT rule.

To solve this problem, you need to create a new frontend IP address for LB1 before you can create the new inbound NAT rules. You can do this by using the Azure portal, PowerShell, or CLI3. After you create a new frontend IP address, you can use it to create the new inbound NAT rules that meet your requirements.

You can't delete a vault that contains backup data. So in this case at first you have to delete the backup of  'SQLD01' before you attempt to delete the vault.

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.

To create a scheduled runbook to increase the processor performance of VM1 at the end of each month, you need to modify the VM size property of VM1. This will allow you to scale up the VM to a larger size that has more CPU cores and memory. You can use Azure Automation to create a PowerShell runbook that changes the VM size using the Set-AzVM cmdlet. You can then schedule the runbook to run at the end of each month using the Azure portal or Azure PowerShell. For more information, see How to resize a virtual machine in Azure using Azure Automation1.

Box 1: Group 1 only

First rule applies

Box 2: Group1 and Group2 only

The exhibit shows that you have an autoscale rule configured for your App Service app named App1. The rule is based on the memory percentage metric, which measures the average amount of memory used by all the instances of your app. The rule has the following settings:

Scale out action: Add 1 instance when the memory percentage is greater than or equal to 80% for a duration of 10 minutes.

Scale in action: Remove 1 instance when the memory percentage is less than or equal to 60% for a duration of 10 minutes.

Instance limits: The minimum number of instances is 2, and the maximum number of instances is 5.

According to the question, during a 30-minute period, App1 uses 60% of the available memory. This means that the scale in action is triggered, but not the scale out action. Therefore, one instance is removed from App1 every 10 minutes, until the minimum number of instances is reached.

Since App1 initially has two running instances, after the first 10 minutes, one instance is removed and App1 has one instance left. However, since the minimum number of instances is set to 2, another instance is added back to App1 to meet the minimum requirement. Therefore, after the first 10 minutes, App1 still has two instances.

After the second 10 minutes, the same process repeats. One instance is removed due to the scale in action, and another instance is added back due to the minimum requirement. Therefore, after the second 10 minutes, App1 still has two instances.

After the third 10 minutes, there is no change in the number of instances, because App1 already has the minimum number of instances. Therefore, after the third 10 minutes, App1 still has two instances.

Therefore, during the 30-minute period, App1 never has more than two instances running at any given time. However, since one instance is removed and added back every 10 minutes, there are four different instances that are used by App1 during the period. Hence, the maximum number of instances for App1 during the period is four.

Azure Import/Export service supports the following of storage accounts:

✑ Standard General Purpose v2 storage accounts (recommended for most scenarios)

✑ Blob Storage accounts

✑ General Purpose v1 storage accounts (both Classic or Azure Resource Manager deployments),

Azure Import/Export service supports the following storage types:

✑ Import supports Azure Blob storage and Azure File storage

✑ Export supports Azure Blob storage. Azure Files not supported.

Only storage4 can be exported.

User 1 can sign in to VMI. = YES 

User 1 has the Virtual Machine User Login role assigned at the scope of RG1. This role allows the user to sign in to virtual machines in the resource group using Azure AD credentials. VMI is a virtual machine in RG1, so User 1 can sign in to it.

User 2 can manage disks and disk snapshots of VMI. = NO 

User 2 has the Disk Snapshot Contributor role assigned at the scope of MG2. This role allows the user to manage disk snapshots in the management group. However, VMI is not in MG2, but in RG1, which is in MG1. Therefore, User 2 does not have the permission to manage disks and disk snapshots of VMI.

User 2 can manage disks and disk snapshots of VM3. = YES 

User 2 has the Disk Snapshot Contributor role assigned at the scope of MG2. This role allows the user to manage disk snapshots in the management group. VM3 is a virtual machine in RG3, which is in Sub2, which is in MG2. Therefore, User 2 has the permission to manage disks and disk snapshots of VM3.

You can filter network traffic to and from Azure resources in an Azure virtual network with a network security group. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources.

You can use a site-to-site VPN to connect your on-premises network to an Azure virtual network. Users on your on-premises network connect by using the RDP or SSH protocol over the site-to-site VPN connection. You don't have to allow direct RDP or SSH access over the internet. And this can be achieved by configuring a deny rule in a network security group (NSG) that is linked to Subnet1 for RDP / SSH protocol coming from internet.

Modify the address space of Subnet1 : Incorrect choice

Modifying the address space of Subnet1 will have no impact on RDP traffic flow to the virtual network.

Modify the address space of the local network gateway : Incorrect choice

Modifying the address space of the local network gateway will have no impact on RDP traffic flow to the virtual network.

Remove the public IP addresses from the virtual machines : Incorrect choice

If you remove the public IP addresses from the virtual machines, none of the applications be accessible publicly by the Internet users.

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.

Change the Service administrator for an Azure subscription

Sign in to Account Center as the Account administrator.

Select a subscription.

On the right side, select Edit subscription details.

Scenario: Designate a new user named Admin1 as the service administrator of the Azure subscription.

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.

Box 1: Selected

Only selected users should be able to join devices

Box 2: Yes

Require Multi-Factor Auth to join devices.

From scenario:

Ensure that only users who are part of a group named Pilot can join devices to Azure AD

Ensure that when users join devices to Azure Active Directory (Azure AD), the users use a mobile phone to verify their identity.

Active Directory Federation Services is a feature and web service in the Windows Server Operating System that allows sharing of identity information outside a company’s network.

Scenario: Technical Requirements include:

Prevent user passwords or hashes of passwords from being stored in Azure.

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.

This reference architecture shows how to deploy VMs and a virtual network configured for an N-tier application, using SQL Server on Windows for the data tier.

Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers:

A SQL database

A web front end

A processing middle tier

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.

Technical requirements include:

Move all the virtual machines for App1 to Azure.

Minimize the number of open ports between the App1 tiers.

As App1 is public-facing we need an incoming security rule, related to the access of the web servers.

Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers: a SQL database, a web front end, and a processing middle tier.

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.

https://learn.microsoft.com/en-us/azure/backup/backup-azure-vms-first-look-arm#back-up-from-azure-vm-settings

Explanation

Scenario:

1. Web administrators will deploy Azure web apps for the marketing department.

2. Each web app will be added to a separate resource group.

3. The initial configuration of the web apps will be identical.

4. The web administrators have permission to deploy web apps to resource groups.

Steps:

1 --> Create a resource group, and then deploy a web app to the resource group.

2 --> From the Automation script blade of the resource group , click Add to Library.

3 --> From the Templates service, select the template, and then share the template to the web administrators .

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.

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

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.

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.

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

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

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  links at the top of the menu to jump to the previous or next period, respectively. For example, 

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.

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.

You can opt in and configure additional recipients to receive your Azure invoice in an email. This feature may not be available for certain subscriptions such as support offers, Enterprise Agreements, or Azure in Open.

Select your subscription from the Subscriptions page. Opt-in for each subscription you own. Click Invoices then Email my invoice.

Click Opt in and accept the terms.

Scenario: During the testing phase, auditors in the finance department must be able to review all Azure costs from the past week.

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.

Box 1: Create a Recovery Services vault

Create a Recovery Services vault on the Azure Portal.

Box 2: Install the Azure Site Recovery Provider

Azure Site Recovery can be used to manage migration of on-premises machines to Azure.

Scenario: Migrate the virtual machines hosted on Server1 and Server2 to Azure.

Server2 has the Hyper-V host role.

Box 1: Create a virtual network gateway and a local network gateway.

Azure VPN gateway. The VPN gateway service enables you to connect the VNet to the on-premises network through a VPN appliance. For more information, see Connect an on-premises network to a Microsoft Azure virtual network. The VPN gateway includes the following elements:

Virtual network gateway. A resource that provides a virtual VPN appliance for the VNet. It is responsible for routing traffic from the on-premises network to the VNet.

Local network gateway. An abstraction of the on-premises VPN appliance. Network traffic from the cloud application to the on-premises network is routed through this gateway.

Connection. The connection has properties that specify the connection type (IPSec) and the key shared with the on-premises VPN appliance to encrypt traffic.

Gateway subnet. The virtual network gateway is held in its own subnet, which is subject to various requirements, described in the Recommendations section below.

Box 2: Configure a site-to-site VPN connection

On premises create a site-to-site connection for the virtual network gateway and the local network gateway.

Scenario: Connect the New York office to VNet1 over the Internet by using an encrypted connection.

Scenario: Litware must meet technical requirements including:

Ensure that VM3 can establish outbound connections over TCP port 8080 to the applications servers in the Montreal office.

IP flow verify checks if a packet is allowed or denied to or from a virtual machine. The information consists of direction, protocol, local IP, remote IP, local port, and remote port. If the packet is denied by a security group, the name of the rule that denied the packet is returned. While any source or destination IP can be chosen, IP flow verify helps administrators quickly diagnose connectivity issues from or to the internet and from or to the on-premises environment.

Scenario: Create a workflow to send an email message when the settings of VM4 are modified.

You can start an automated logic app workflow when specific events happen in Azure resources or third-party resources. These resources can publish those events to an Azure event grid. In turn, the event grid pushes those events to subscribers that have queues, webhooks, or event hubs as endpoints. As a subscriber, your logic app can wait for those events from the event grid before running automated workflows to perform tasks - without you writing any code.
