Microsoft Azure Administrator Associate Practice Test (AZ-104)

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.

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.

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.

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 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.

Assigning a role at the resource group scope grants permissions only within that specific resource group and its resources. Permissions do not flow upward to the subscription level. In Azure, permissions inherited from higher scopes apply to lower scopes, but not vice versa. Therefore, assigning a role at a lower scope does not confer permissions at a higher scope.

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.

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.

The first step in configuring disaster recovery with Azure Site Recovery is to create an RSV (Recovery Services vault) in the target region where you want to replicate your virtual machines. The RSV acts as a storage entity that holds the metadata and configuration information for the replication, as well as the recovery points. By creating the vault in the West Europe region, you ensure that your replicated data is stored in the region that will act as the failover location.

Option A is incorrect because you cannot enable replication until you have an RSV to manage the replication process. Option C is incorrect because configuring a backup policy pertains to Azure Backup, not replication for disaster recovery. Option D is incorrect because for Azure Virtual Machines, Azure Site Recovery provides agentless replication, so installing an agent is not necessary.

The 'IP flow verify' feature in Azure Network Watcher allows you to test the communication between a source and a destination IP address and port, and reports whether the traffic is allowed or denied by NSG rules or user-defined routes. This makes it the appropriate tool to determine if NSG rules are affecting the traffic to the endpoint. 'Connection troubleshoot' helps diagnose a connection but does not show NSG rule evaluations. 'Packet capture' collects network traffic data from virtual machines but does not directly indicate NSG rule impact. 'Next hop' determines the next hop for packets but does not provide NSG rule information.

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.

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.

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.
