Microsoft Azure Administrator Associate Practice Test (AZ-104)

To automatically register Windows 10 devices in Azure Entra ID when users sign in with their corporate credentials, you should configure Azure AD Join. Azure AD Join allows devices to be joined directly to Azure AD, enabling centralized management and access to resources. This is suitable for corporate-owned devices and simplifies the sign-in experience for users. Azure AD registered devices are typically used for personally owned devices (BYOD) and do not provide the same level of management. Windows Hello for Business is a sign-in method that enhances authentication security but does not handle device registration. Hybrid Azure AD Join is intended for devices joined to an on-premises Active Directory domain that are also registered with Azure AD; since there is no mention of on-premises Active Directory in this scenario, Azure AD Join is the appropriate choice.

By assigning licenses to a group in Azure Entra ID, you ensure that all current and future members of the group automatically receive the licenses, and licenses are revoked when users leave the group. This method is known as group-based licensing and simplifies license management. Assigning licenses directly to each user is time-consuming and does not automatically update when group membership changes. Dynamic device groups manage devices, not user accounts or licenses. Azure Policy is used for policy-based management and cannot assign licenses to users.

Creating a shared access signature (SAS) token linked to a stored access policy allows you to grant temporary access to the vendor and manage it centrally. By associating the SAS with a stored access policy, you can revoke the access by modifying or deleting the policy before its expiration without impacting other users. Sharing the storage account key compromises security and revoking it would affect all services using that key. Generating a user delegation SAS does not offer a way to revoke access before expiration without regenerating keys, which could disrupt other users. Changing the container's access level to public exposes your data to anyone with the URI, which is not secure.

To include a virtual machine in the ARM template and connect it to the existing virtual network, adding new resources for the virtual machine and its network interface in the 'resources' section is necessary. This ensures that the virtual machine and its dependencies are properly defined and deployed within the same template. Modifying parameters or variables would not create the actual resources; they only define values used by resources. The outputs section is used to return values from the deployment and does not affect resource creation.

To achieve automatic updates to the group membership based on user attributes, you should create a security group with dynamic user membership using a department attribute query. This allows Azure Entra ID to automatically add or remove users from the group when their department attribute changes. Assigned membership requires manual management of group members, which does not meet the requirement for automatic updates. A Microsoft 365 group is typically used for collaboration features in Microsoft 365 services and may not be necessary if those features aren't required. An administrative unit is used for delegating administrative permissions and scoping administrative tasks, not for grouping users based on attributes.

Configuring Azure Entra ID authentication for the storage account enables users to access blobs using their corporate credentials. This approach integrates with your organization's existing identity management, enhancing security and simplifying access control. Using shared access signatures or distributing access keys would require managing and securing keys or tokens, which you aim to avoid. Enabling anonymous access would significantly reduce security and is not appropriate for sensitive data.

Shared Access Signatures (SAS) enable you to grant clients limited access rights to storage resources without exposing your account keys. A SAS token specifies permissions and an expiration time, enhancing security when sharing resources. Managed Identities allow Azure services to authenticate to other services but do not directly delegate storage permissions. Access Control Lists (ACLs) are used to define permissions for files and directories in Azure Data Lake Storage Gen2 but are not used for time-limited access. Stored Access Policies help manage SAS by providing additional restrictions but are not used alone to delegate permissions.

The most efficient method is to use the bulk create users feature in Azure Entra ID. This feature allows the administrator to import multiple users at once by uploading a CSV file. Manually creating users through the portal is impractical for a large number of accounts. While a PowerShell script could automate the process, it requires scripting knowledge and additional time to develop and test. Syncing from an on-premises Entra ID is not applicable if the users are not present there.

Including a custom script extension in the template is the best way to automatically install additional software on the server after deployment. Extensions like the Custom Script Extension allow you to run scripts during or after the provisioning process as part of the deployment. This method ensures that the software installation is automated and integrated within the template, providing consistency and scalability. Using Azure CLI or Azure Automation requires additional configurations outside the template and does not embed the installation process within the deployment. Manually installing the software is inefficient and does not leverage automation.

Administrative Units in Azure Entra ID allow you to delegate administrative permissions to specific subsets of users or groups within your organization, such as by department or region. By using Administrative Units, you can assign administrators to manage only the users and groups within a particular Administrative Unit, without giving them broader access to other resources in Azure Entra ID. Other features like Azure Entra ID Privileged Identity Management, Management Groups, and Role-Based Access Control (RBAC) do not provide the necessary scope limitation at the department level within Azure AD user and group management.

Creating a new cloud-based user with a username and password allows you to set up an account without requiring an existing email address. The user will receive a unique User Principal Name (UPN) and can sign in using the credentials you provide. Inviting a guest user requires an email address to send the invitation. Using synchronization tools to sync an account from on-premises is not applicable since there is no on-premises account to synchronize. Creating an application registration is intended for application identities, not individual user accounts.

To achieve this, you should set the storage account's firewall settings to permit access from the required external sources. This involves configuring the firewall to allow traffic only from the specific public IP addresses associated with your on-premises locations. This approach effectively blocks all other network traffic over the Internet. Integrating the storage account with a virtual network in Azure won't help because on-premises networks aren't part of Azure's virtual networks. Enabling private endpoints restricts access to within Azure virtual networks or through private connections, not over the Internet from specific external locations. Activating Azure Active Directory authentication manages identity-based access but doesn't control network-level access based on source addresses.

To meet the requirements, you should create a FileStorage storage account with the premium performance tier. FileStorage accounts are specifically designed for high-performance Azure Files workloads and support both SMB (Server Message Block) and NFS (Network File System) protocols. The premium tier provides the necessary low latency and high throughput for performance-intensive applications. Additionally, data in Azure Storage is encrypted at rest by default, ensuring the security of sensitive information. General-purpose v2 storage accounts with standard performance do not offer the required performance levels. Blob storage accounts are intended for object storage and do not support file shares. General-purpose v2 storage accounts with premium performance tier do not support premium file shares with NFS; this capability is exclusive to FileStorage accounts.

To connect virtual networks in different subscriptions within the same Azure region, you can create a virtual network peering between them. By using virtual network peering with resource IDs, you enable direct connectivity between VNetA and VNetB without the need for additional gateways or complex configurations. This approach provides low-latency, high-bandwidth connectivity between the networks. Other options like ExpressRoute or VPN connections are unnecessary and more complex for this scenario, and an Azure Load Balancer does not facilitate network connectivity between virtual networks.

Using Azure Key Vault to store and manage the storage account access keys is the best method. Azure Key Vault provides a secure, centralized repository for managing secrets, keys, and certificates, including storage account access keys. It offers features like automated key rotation, fine-grained access control through Azure RBAC (Role-Based Access Control), and logging of key usage. While manually regenerating keys or automating key regeneration with scripts can help with rotation, they do not provide the same level of security, auditing, and management capabilities. Implementing Azure AD authentication reduces reliance on access keys by enabling identity-based access, but access keys may still be required for certain applications or scenarios.
