AZ-104 Exam Simulation — 100 Questions

Question 1

A storage automation service principal must upload, read, and delete blob data in one container by using Microsoft Entra authentication. It must not manage storage account settings, keys, or other containers. Which approach is best?

Accepted Answer

Create a custom role with blob dataActions only and assign it at the container scope.. Option B is correct because it creates a custom Azure RBAC role with only the required blob data actions (e.g., Microsoft.Storage/storageAccounts/blobServices/containers/blobs/read, write, delete) and assigns it at the container scope. This ensures the service principal can upload, read, and delete blobs in that specific container using Microsoft Entra authentication, without any permissions to manage storage account settings, keys, or other containers.

Answer

Assign Storage Account Contributor at the resource group scope.

Answer

Assign Reader and give the service principal a storage account access key.

Answer

Assign Contributor at the subscription scope and restrict access with naming conventions.

Question 2

A subnet contains several application servers. You need to allow inbound TCP 3389 only from a management subnet named Subnet-Mgmt and deny RDP from all other sources. What should you do?

Accepted Answer

Create an NSG rule allowing TCP 3389 from the Subnet-Mgmt address range and rely on the default deny afterward.. Option A is correct because Network Security Groups (NSGs) in Azure filter traffic based on rules that are evaluated in priority order. By creating an inbound rule that allows TCP 3389 (RDP) from the Subnet-Mgmt address range, and relying on the default implicit deny rule that blocks all other inbound traffic, you effectively restrict RDP access to only the management subnet. No additional configuration is needed to deny traffic from other sources, as the default deny handles that automatically.

Answer

Create a route table that sends RDP traffic to the management subnet.

Answer

Deploy a private endpoint for each application server.

Answer

Enable service endpoints on the application subnet.

Question 3

A subscription admin wants to investigate who changed a resource and also review the platform-generated events for that subscription. Which two types of logs can be sent to Log Analytics and queried later? Select two.

Accepted Answer

Activity log entries. The Activity log (option A) records subscription-level events such as who created, modified, or deleted a resource, making it essential for investigating administrative changes. Resource diagnostic logs (option B) capture platform-generated events emitted by a resource itself (e.g., Azure SQL Database audit logs, network security group flow logs), which can be sent to Log Analytics for querying. Both log types can be configured to stream to a Log Analytics workspace, enabling Kusto Query Language (KQL) analysis.

Answer

Azure Backup vault names

Answer

Virtual network address spaces

Answer

Managed disk size settings

Question 4

Based on the exhibit, which Azure feature should the administrator use to track this kind of platform-wide service issue?

Accepted Answer

Service Health, because it reports Azure platform incidents that affect customers in a region.. Service Health is the correct feature because it provides a personalized dashboard of all Azure service incidents, planned maintenance, and health advisories that impact the customer's subscriptions and regions. It aggregates platform-wide issues (e.g., regional outages or degradation) that Azure engineering has confirmed, making it the appropriate tool for tracking a platform-wide service issue affecting multiple resources in a region.

Answer

Resource Health, because it shows whether a specific virtual machine is healthy or unavailable.

Answer

Activity Log, because it lists every administrative action taken in the subscription.

Answer

Azure Advisor, because it gives recommendations to improve the virtual machine configuration.

Question 5

An administrator wants a script running on an Azure VM to create a resource in Azure without storing any passwords or client secrets on the VM. What should the administrator configure first?

Accepted Answer

A system-assigned managed identity on the VM. A system-assigned managed identity enables an Azure VM to authenticate to Azure services (e.g., Azure Resource Manager) without storing any credentials in the VM. The identity is automatically created and managed by Azure, and the VM can obtain an access token from Azure AD via the Instance Metadata Service (IMDS) endpoint (169.254.169.254) using a simple HTTP call. This allows the script to securely create resources without hardcoding passwords or client secrets.

Answer

A shared local account on the VM

Answer

An Azure Policy exemption

Answer

A public IP address on the VM

Question 6

A PowerShell script runs on an Azure VM every night and uses Azure CLI commands to create tags and VM resources in another subscription. The script cannot store a password or client secret. What should it use to authenticate to Azure?

Accepted Answer

az login --identity.. Option B is correct because the script runs on an Azure VM and can use a managed identity to authenticate without storing any secrets. The `az login --identity` command uses the VM's system-assigned or user-assigned managed identity to obtain an Azure AD access token via the Azure Instance Metadata Service (IMDS) endpoint. This satisfies the requirement of no password or client secret storage.

Answer

az login with a username and password.

Answer

Connect-AzAccount with device code authentication.

Answer

An app registration secret stored in a PowerShell variable.

Question 7

A storage account becomes unavailable because Azure has a regional platform issue. The operations team wants a notification whenever Azure marks the resource or region unhealthy, and they want to avoid continuous log ingestion just to detect the outage. What should they configure?

Accepted Answer

A Service Health alert based on the Activity log, scoped appropriately.. Option C is correct because a Service Health alert, configured from the Azure Activity log, provides proactive notifications when Azure services or regions experience an outage or degradation. This alert is triggered by Azure's own health signals, eliminating the need for continuous log ingestion or custom metric monitoring to detect platform-level issues.

Answer

A metric alert on storage capacity with an action group.

Answer

A log alert on storage diagnostic logs that watches for 503 responses.

Answer

An Azure Policy assignment that audits the storage account state.

Question 8

A support engineer must start and restart one specific virtual machine from the Azure portal, but must not be able to delete the VM, change networking, or grant access to others. Which two actions should be included in a custom role? Select two.

Accepted Answer

Microsoft.Compute/virtualMachines/start/action grants the ability to start the VM without broader management permissions.. Option A is correct because Microsoft.Compute/virtualMachines/start/action is a specific permission that allows starting a VM without granting broader management capabilities like deletion or network changes. This action is part of the Azure RBAC role definition and can be included in a custom role to limit the support engineer's scope to only starting the VM.

Answer

Microsoft.Compute/virtualMachines/delete gives the ability to remove the VM from the subscription.

Answer

Microsoft.Network/networkInterfaces/write is needed because a VM start or restart always requires NIC modification rights.

Answer

Microsoft.Authorization/roleAssignments/write would let the engineer grant access to other users and manage permissions.

Question 9

A storage account must stay online for applications, but administrators have a temporary freeze on configuration changes. Users can still view the account, but attempts to change the access tier, create a container, or update networking all fail. What most likely caused the behavior?

Accepted Answer

A ReadOnly lock was applied to the storage account.. A ReadOnly lock (Azure Resource Manager lock) prevents any modification to the storage account, including changing the access tier, creating containers, or updating networking settings, while still allowing read operations like viewing the account. This matches the described behavior exactly because the lock is applied at the resource scope and blocks all write/delete operations, but does not affect read access.

Answer

A CanNotDelete lock was applied to the storage account.

Answer

An Azure Policy audit assignment was applied to the storage account.

Answer

The account was moved to a different subscription.

Question 10

You create a private endpoint for an Azure Storage account. Virtual machines in VNet-Prod must resolve the storage account name to the private IP address of that endpoint. Which Azure feature should you configure?

Accepted Answer

A private DNS zone linked to VNet-Prod. A private endpoint uses a private IP address from the VNet, but DNS resolution must be explicitly configured to map the storage account's FQDN to that private IP. By creating a private DNS zone (privatelink.blob.core.windows.net) linked to VNet-Prod, Azure automatically creates an A record for the private endpoint IP, enabling VMs to resolve the storage account name to the private IP instead of the public IP.

Answer

A user-defined route

Answer

An Azure Firewall policy

Answer

A Recovery Services vault

Question 11

A support engineer must start, stop, and restart only one virtual machine named vm-app01. The engineer should not gain permissions on any other virtual machine in the subscription. What is the best scope for the role assignment?

Accepted Answer

The vm-app01 virtual machine resource itself.. Option C is correct because Azure RBAC allows role assignments to be scoped to individual resources, such as a specific virtual machine. By assigning a role like 'Virtual Machine Contributor' at the vm-app01 resource scope, the support engineer will have permissions to start, stop, and restart only that VM, and no other resources in the subscription or resource group.

Answer

The entire subscription that contains vm-app01.

Answer

The resource group that contains vm-app01.

Answer

The management group that contains the subscription.

Question 12

A team deploys a Linux VM that must read secrets from Azure Key Vault without storing any usernames, passwords, or client secrets on the VM. What should the administrator enable on the VM?

Accepted Answer

A system-assigned managed identity. A system-assigned managed identity enables the Linux VM to authenticate to Azure Key Vault without any stored credentials. Azure automatically creates a service principal in Entra ID for the VM, and the VM can obtain an access token from the Azure Instance Metadata Service (IMDS) endpoint (169.254.169.254) to authenticate to Key Vault. This eliminates the need to store usernames, passwords, or client secrets on the VM.

Answer

A storage account access key

Answer

A service endpoint on the VM subnet

Answer

A user account in Entra ID with a stored password

Question 13

A team has Windows VMs in a subnet that need to access an Azure Storage account. The storage account should remain reachable through its public endpoint, but only traffic from that one subnet should be allowed. Which configuration best meets the requirement?

Accepted Answer

Enable a service endpoint on the subnet and add a virtual network rule for that subnet on the storage account firewall.. Option B is correct because a service endpoint extends the virtual network private address space to the storage account, allowing traffic from the specified subnet to reach the storage account via the Azure backbone while keeping the public endpoint accessible. By adding a virtual network rule on the storage account firewall, you restrict access to only traffic originating from that subnet, meeting the requirement of allowing only that subnet through the public endpoint.

Answer

Create a private endpoint and disable public network access on the storage account.

Answer

Place the subnet behind a NAT gateway and use a shared public IP.

Answer

Add a VPN gateway and route storage traffic through the branch office.

Question 14

A team needs one Azure Files share that can be mounted by both Windows and Linux VMs. The VMs are joined to the same on-premises Active Directory Domain Services domain, and the security team forbids storage account keys. The team also wants to manage access with existing AD group memberships. What should the administrator configure?

Accepted Answer

Use Azure Files over SMB and enable AD DS authentication. Option A is correct because Azure Files supports SMB protocol, which can be mounted by both Windows and Linux VMs. By enabling AD DS authentication, the administrator can use existing on-premises Active Directory group memberships to control access to the file share without requiring storage account keys, satisfying the security team's requirement.

Answer

Use a blob container and mount it through the Blob API

Answer

Use anonymous access on an Azure File share

Answer

Use a premium NFS file share with a shared access signature

Question 15

A subscription already grants Contributor to an application team. The organization wants to prevent deployments in unsupported Azure regions and ensure every new resource has an Environment tag. Which two controls should be implemented with Azure Policy rather than RBAC? Select two.

Accepted Answer

Assign an allowed-locations policy at the management group or subscription scope.. Option A is correct because Azure Policy can enforce an 'allowed-locations' policy at the management group or subscription scope to restrict resource deployment to only approved Azure regions. This is a governance control that operates declaratively, evaluating resource properties against policy rules before or after creation, unlike RBAC which controls identity-based permissions. Option C is correct because Azure Policy can enforce the 'Environment' tag on new resources using a 'require a tag and its value' policy, ensuring compliance without modifying role assignments.

Answer

Create a custom RBAC role that blocks resources deployed outside approved regions.

Answer

Add a CanNotDelete lock to every resource group.

Answer

Grant User Access Administrator to the deployment team.

Question 16

A switch administrator wants log entries from multiple devices to be collected on one central server for later review. Which service should be configured?

Accepted Answer

Syslog. Syslog is the standard protocol (RFC 5424) used for collecting and centralizing log messages from network devices, servers, and other infrastructure components. By configuring each device to send syslog messages to a central syslog server, the administrator can aggregate logs for unified review, monitoring, and troubleshooting. This directly meets the requirement for centralized log collection.

Answer

DNS

Answer

NTP

Answer

SNMP trap suppression

Question 17

A hub VNet already has a VPN gateway connected to on-premises. A new spoke VNet must reach on-premises through the hub gateway and should not deploy its own gateway. What configuration should be enabled on the peering?

Accepted Answer

Enable gateway transit on the hub peering and Use remote gateways on the spoke peering.. Option A is correct because enabling 'Use remote gateways' on the spoke VNet peering and 'Allow gateway transit' on the hub VNet peering allows the spoke VNet to route traffic to on-premises through the hub's VPN gateway without deploying its own gateway. This configuration leverages BGP routes (if the VPN gateway is route-based) to propagate on-premises prefixes to the spoke, enabling transitive routing across the peering.

Answer

Create a service endpoint from the spoke to the hub.

Answer

Add a default route to Internet in the spoke subnet.

Answer

Enable accelerated networking on the spoke subnet.

Question 18

An administrator is deploying a site-to-site VPN gateway in the Azure portal. The deployment fails validation because the gateway does not have a public-facing address to terminate the tunnel. What must be created and associated with the VPN gateway?

Accepted Answer

A public IP address resource associated with the VPN gateway.. A site-to-site VPN gateway in Azure requires a public IP address to terminate the IPSec tunnel from the on-premises device. The public IP address resource must be created and associated with the VPN gateway during deployment; without it, the gateway has no routable endpoint for the tunnel, causing validation to fail.

Answer

A load balancer frontend IP configuration in front of the gateway subnet.

Answer

A NAT gateway attached to GatewaySubnet.

Answer

A private endpoint for the virtual network gateway resource.

Question 19

A team has an approved Windows VM that already includes their application, patches, and monitoring agent. They want future VMs to start with the same configuration. What should they use?

Accepted Answer

A managed image created from the approved VM. A managed image captures the entire VM configuration, including the OS, application, patches, and monitoring agent, allowing you to create multiple identical VMs from a single source. Unlike a snapshot, which is tied to a specific disk and requires manual steps to replicate the full VM setup, a managed image provides a reusable template for consistent deployments. This approach ensures future VMs start with the exact same configuration as the approved VM.

Answer

An availability set

Answer

A snapshot of the OS disk

Answer

A larger virtual machine size

Question 20

A team in RG-Apps must be able to start, stop, and deallocate virtual machines and read their properties. Built-in roles available to the team are broader than necessary. What should the administrator do?

Accepted Answer

Create a custom role with only the required VM actions and assign it at RG-Apps scope.. Option B is correct because the team needs specific actions (start, stop, deallocate, read properties) that are a subset of the Virtual Machine Contributor role's permissions. Creating a custom role with only the required actions (Microsoft.Compute/virtualMachines/start/action, Microsoft.Compute/virtualMachines/deallocate/action, Microsoft.Compute/virtualMachines/read, etc.) and assigning it at the RG-Apps scope provides least-privilege access without granting broader capabilities like creating or deleting VMs.

Answer

Assign Virtual Machine Contributor at the subscription scope.

Answer

Assign Reader and Virtual Machine Contributor together at the resource group scope.

Answer

Assign Owner at the resource group scope to avoid troubleshooting access issues.
