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.

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.

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.

In this scenario, App1 consists of three distinct tiers — web front end, processing middle tier, and SQL database — each containing five virtual machines. The technical requirement specifies that the company must minimize the number of open ports between the App1 tiers, move all tiers of App1 to Azure, and ensure that all VMs are protected by backups.

According to Microsoft Azure architecture best practices for multi-tier applications (from Azure Architecture Center and the Azure Administrator curriculum), the optimal design involves:

Deploying all tiers of App1 into a single virtual network (VNet).

This allows all components of the application to communicate securely using private IP addresses.

Keeping all tiers within a single VNet simplifies management, security, and monitoring while supporting Network Security Groups (NSGs) for inter-tier traffic control.

Microsoft Documentation Extract:

“Use a single virtual network to host multi-tier applications. Divide the virtual network into multiple subnets, each representing a tier, and use network security groups (NSGs) to control traffic flow between tiers.”

(Source: Microsoft Learn – Design and implement virtual networks in Azure)

Creating separate subnets for each application tier (3 total).

Subnet 1: Web tier (internet-facing, HTTPS traffic)

Subnet 2: Application/Processing tier (internal communication only)

Subnet 3: Database tier (private, no internet access)

Using NSGs, administrators can explicitly allow or deny traffic between subnets, thus minimizing open ports between tiers and meeting the security requirement.

Microsoft Documentation Extract:

“Subnets provide isolation and segmentation within a virtual network. Each tier of an application should be deployed in its own subnet to apply network security policies and control exposure.”

(Source: Microsoft Learn – Azure virtual network design best practices)

Backups and Storage Requirements:

All VMs can use Azure Backup integrated with Recovery Services Vaults, which supports VM-level backup in a single VNet environment.

The blueprint files are stored in Azure Blob Storage with the archive tier, ensuring compliance with the storage and access control requirements.

By using one virtual network and three subnets, Contoso ensures efficient management, minimized administrative overhead, secure isolation of application tiers, and full compliance with Azure governance and security recommendations.

✅ Final Verified Answer:

Number of virtual networks: 1

Number of subnets: 3

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.

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.

In this scenario, Contoso Ltd. must designate a new user named Admin1 as the service administrator of the Azure subscription and ensure that Admin1 receives email alerts about service outages.

In Azure, there are three classic administrative roles associated with subscriptions:

Account Administrator – The individual who created the subscription and manages billing.

Service Administrator – The primary contact responsible for managing services and resources in the subscription.

Co-Administrator – Has the same management privileges as the Service Administrator but cannot change subscription associations.

According to Microsoft Azure Administrator documentation, to change the Service Administrator, you must perform the following steps:

In the Azure portal, navigate to Subscriptions.

Select the specific subscription.

Under Settings, choose Properties.

In the Service Administrator field, update the name and email address to that of the new administrator (in this case, Admin1).

This modification ensures that Admin1 becomes the Service Administrator, and Azure will automatically send service-related notifications and outage alerts to that user’s registered email address, as defined by Microsoft’s subscription notification process.

Option B (IAM settings) is used for Role-Based Access Control (RBAC) and assigning Azure Resource Manager roles such as Owner, Contributor, or Reader. However, RBAC roles do not change the Service Administrator at the subscription level — that’s only done through the Properties blade.

Options C (AAD Properties) and D (AAD Groups) are unrelated to subscription-level administrative settings.

Therefore, the verified and Microsoft-documented answer is:

✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.

Final Verified Answer: ✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.

✅ Yes, Yes, No

Azure role-based access control (Azure RBAC) for Azure file shares requires identity-based authentication integration. According to the Microsoft Azure Administrator documentation, this feature is only supported for StorageV2 (general purpose v2) and FileStorage account types.

In this scenario:

You are required to grant Group4 read-only access using Azure RBAC on Azure file shares.

The technical requirement specifies:

“Whenever possible, grant Group4 Azure RBAC read-only permissions to the Azure file shares.”

From the case study data:

Storage Account

Kind

Identity-based Access

storage1

Storage (general purpose v1)

Azure AD DS

storage2

StorageV2

Disabled

storage3

BlobStorage

N/A

storage4

FileStorage

Azure AD DS

The Storage (general purpose v1) type (storage1) does not support Azure AD or Azure RBAC integration for file shares. Microsoft documentation clearly states that “StorageV1 accounts must be upgraded to StorageV2 to support Azure AD authentication and RBAC role assignments.”

Meanwhile, FileStorage (storage4) already supports Azure AD Domain Services (Azure AD DS) and RBAC role assignment; hence no further modification is required there. However, to make storage1 compatible, it must be converted from StorageV1 to StorageV2.

Once converted to StorageV2, you can then:

Enable identity-based access for Azure file shares.

Assign Azure RBAC roles (e.g., Storage File Data Reader) to Group4.

Microsoft-Documented Requirements Summary:

Supported Account Types: StorageV2 or FileStorage

Unsupported: StorageV1 and BlobStorage

Required RBAC Roles for Read-Only Access:

Storage File Data Reader (or custom read-only role)

Thus, to meet the organization’s requirement to provide Azure RBAC read-only permissions, you must change the account type of storage1 to StorageV2, ensuring both storage1 and storage4 can be managed with Azure RBAC.
