Microsoft Azure Administrator Associate Practice Test (AZ-104)

Implementing a private endpoint connection to the storage account meets the requirements by assigning a private IP address from your virtual network to the storage account. This ensures all traffic remains within the Azure network infrastructure and does not traverse the public internet. Configuring a virtual network service endpoint allows resources in the VNet to use optimized routing to the service, but the service is still accessed over its public IP address. Enabling Azure Firewall provides traffic filtering but does not change the path of the traffic. Creating a user-defined route does not provide private connectivity to the storage account.

Creating a private endpoint for the storage account is the correct solution. A private endpoint assigns the storage account a private IP address within the specified subnet, ensuring that only resources within that subnet can access it, and internet access is blocked. Service endpoints enable access to Azure services over the Azure backbone network but do not disable the public endpoint and cannot restrict access to a single subnet. Configuring a network security group cannot prevent access over the public internet to the storage account's public endpoint. Virtual network peering connects virtual networks but does not provide the required access control.

Azure Files provides fully managed shared storage accessible via the Server Message Block (SMB) protocol, allowing multiple clients to read and write files simultaneously. Azure Blob Storage is optimized for storing unstructured object data and does not support SMB access. Azure Queue Storage is used for messaging between services, and Azure Table Storage is for storing structured NoSQL data. Therefore, Azure Files is the appropriate service for creating a network file share accessible via SMB.

When creating a backup vault for Azure resources, it's important to place the vault in the same region as the resources being backed up. This minimizes latency and ensures seamless integration between the backup service and the resources. Selecting a different region, the default subscription region, or any region without considering the resource location can lead to increased latency and potential issues with backup and restore operations.

Network Watcher Connection Monitor is the correct tool because it allows administrators to monitor connectivity between Azure resources and external endpoints over time, providing continuous insights into connection health, latency, and packet loss. IP Flow Verify is used to check whether traffic is allowed or denied based on security rules for a specific flow but does not provide ongoing monitoring. Traffic Analytics analyzes network traffic flow logs for insights and trends but doesn't test connectivity to specific endpoints. NSG Flow Logs capture information about ingress and egress IP traffic through Network Security Groups but do not actively test or monitor connectivity health.

To move a virtual machine to a different resource group, you must first stop (deallocate) the VM. This is because certain operations, including moving resources, cannot be performed on a running VM. Option B is correct because it involves stopping VM1 and then using the Azure Portal to change its resource group to RG2. Option A is incorrect because moving a running VM is not supported and will result in an error. Option C is unnecessarily complex and involves manual steps that are not needed when you can move the VM directly after stopping it. Option D involves creating a new VM from a snapshot, which does not actually move the existing VM and could lead to data inconsistency or loss of settings.

To enable the web frontend and background service to communicate over localhost, they must be deployed within the same container group in Azure Container Instances (ACI). A container group allows multiple containers to share the same network namespace and local IP address, facilitating inter-container communication via localhost. Deploying them in separate container groups or using different services would not allow localhost communication.

The Kubernetes Cluster Autoscaler automatically adjusts the number of nodes in an Azure Kubernetes Service (AKS) cluster based on the resource demands of the workloads. It scales out by adding nodes when resource demands increase and scales in by removing nodes when demands decrease, ensuring efficient resource utilization and cost savings. Azure Load Balancer distributes network traffic across resources but does not handle scaling of cluster nodes. Azure Traffic Manager provides DNS-based traffic routing across regions, and Azure Application Gateway is a web traffic load balancer; neither manages node scaling in AKS.

You should use Network Performance Monitor to achieve this. Network Performance Monitor is a solution within Azure Monitor that provides comprehensive monitoring of network performance between various endpoints, including across Azure regions. It helps detect network issues like latency and packet loss, enabling you to diagnose and address connectivity problems effectively.

Other options are less suitable: Azure Monitor Metrics collects and analyzes metrics from Azure resources but doesn't specialize in network connectivity monitoring. Azure Network Watcher provides tools for network diagnostics and troubleshooting but doesn't offer continuous performance monitoring between regions. Azure Traffic Manager is used for DNS-based traffic routing to distribute traffic optimally but doesn't provide network performance monitoring capabilities.

You can generate a reusable Azure Resource Manager (ARM) template from the deployment in the Azure portal. This template captures the configuration of all resources within the resource group, allowing you to redeploy them consistently. Azure Backup does not provide a template for redeployment; it is used for data backup and recovery. Diagnostic logs record activity but do not create templates for deployments. Azure Resource Explorer lets you view resource details but does not generate deployment templates.

Using the bulk update feature in Azure Entra ID by uploading a CSV file allows you to efficiently update multiple user properties at once. This method is designed for making large-scale changes and saves time compared to updating each user individually. Azure AD provides templates and guidance to ensure the CSV file is formatted correctly for the bulk operation.

The Cool storage tier is designed for data that is infrequently accessed and stored for at least 30 days. It offers lower storage costs compared to the Hot tier and provides quick access times suitable for periodic access with minimal latency. The Archive tier, while offering the lowest storage costs, is not suitable because data retrieval can take hours and is not appropriate for data that needs periodic access with minimal latency. The Hot tier is optimized for frequently accessed data but comes with higher storage costs. The Premium tier is designed for workloads that require high throughput and low latency, but at a higher cost and is often used with Azure Page Blobs, not Block Blobs used in this scenario.

By creating a blob lifecycle management policy, you can define rules to automatically transition blobs to lower-cost access tiers (Hot, Cool, Archive) based on specified conditions such as the age of the data. This automates the management of blob data lifecycle and helps optimize costs without manual intervention. Other options require manual processes or do not address automatic tiering based on age.

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 parameters section in an ARM template allows you to define values that can be customized during deployment, making templates reusable and flexible. variables are used to store values that are computed from parameters or hard-coded values but cannot be changed during deployment. The resources section specifies the Azure resources to deploy. The outputs section defines any values that should be returned after the deployment completes.
