Microsoft Azure Administrator Associate Practice Test (AZ-104)

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 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.

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.

The 'IP flow verify' feature in Azure Network Watcher is used to check if a packet is allowed or denied to or from a virtual machine. It tests the traffic against configured network security group (NSG) rules and returns the specific rule that allowed or denied the traffic. This makes it the correct tool for the scenario. 'Connection troubleshoot' provides a comprehensive, point-in-time connection check but does not specify which NSG rule is responsible for a failure. 'Packet capture' collects raw network traffic for deep analysis but does not directly report on NSG rule evaluations. 'Next hop' is used to diagnose routing issues by showing the next hop in the traffic path, not for checking security rules.

The 'Size' setting allows you to select the computational resources for your virtual machine, including the number of CPUs and the amount of memory. The 'Image' option specifies the operating system and software configuration, the 'Resource Group' is used for organizing resources, and the 'Availability Set' enhances availability by distributing VMs across fault domains.

To successfully peer two virtual networks, their IP address spaces must not overlap. Azure requires that the address ranges for each virtual network are unique to ensure proper routing of traffic between them. It is not necessary for the virtual networks to be in the same subscription or resource group; peering can be configured across subscriptions and resource groups. Enabling network security group (NSG) flow logs is not a requirement for virtual network peering.

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.

Azure Key Vault's managed storage account keys feature is the recommended approach. Key Vault stores the access keys as secrets, controls access through Azure RBAC, and can automatically regenerate (rotate) the keys on a defined schedule without exposing their values to users. Manual rotation-whether through the portal or scripts-requires additional effort and lacks centralized auditing. Switching entirely to Azure AD authentication is ideal when possible but does not solve the stated need to continue using access keys and rotate them regularly.

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.

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.

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.

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.

In Azure, role-based access control (RBAC) permissions are inherited from parent scopes down to child scopes. A role assigned at a resource group scope grants permissions only to that resource group and the resources within it. These permissions do not propagate upwards to the subscription level. Therefore, the user with the Contributor role on 'RG-WebApp' can create, manage, and delete resources only within that specific resource group. They do not have any permissions at the subscription level or in other resource groups.

The Azure Container Networking Interface (CNI) networking model allows each pod in an AKS cluster to receive an IP address from the Azure virtual network subnet. This setup enables pods to communicate directly with other resources on the virtual network and on-premises networks connected via VPN or ExpressRoute, without network address translation (NAT). The kubenet networking model assigns IP addresses at the node level and uses NAT for pod communication, which does not provide the required direct pod connectivity. Virtual Network (VNet) peering connects Azure virtual networks but does not assign IP addresses to pods. Azure Network Policy is used to define network traffic rules but does not affect the underlying networking model or pod IP assignment.

AzCopy is a command-line tool that allows for efficient data transfer to and from Azure Storage accounts. It supports scripting and automation, making it ideal for transferring large datasets. Azure Storage Explorer is a graphical tool better suited for manual operations and smaller data transfers. The Azure Import/Export service involves shipping physical disks to Microsoft data centers, which is unnecessary given the reliable internet connection. The Azure Portal is not designed for transferring large amounts of data or for automation through scripts.

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.

The first step in configuring disaster recovery for Azure VMs with Azure Site Recovery is to create a Recovery Services vault (RSV). This vault is a management entity that contains the disaster recovery configuration, policies, and metadata. It is a best practice and a requirement to create the vault in a region other than the source region; placing it in the target West Europe region ensures the vault is available during a North Europe regional outage. The vault orchestrates the replication process, where replicated data and recovery points are stored in storage accounts in the target region.

The other options are incorrect. Enabling replication is a subsequent step that is configured within the Recovery Services vault. Configuring a backup policy is an action related to Azure Backup, not Azure Site Recovery's replication capabilities. For Azure-to-Azure VM disaster recovery, the process is agentless, meaning you do not need to manually install a replication agent on the source virtual machines.

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.

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.

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.
