AZ-104 Practice Exam 4 — 20 Questions

Question 1

A Windows file server VM in Azure must mount an Azure file share by using existing Active Directory Domain Services credentials instead of a storage account key. The organization already has domain-joined Windows servers in the environment. What should the administrator configure on the storage account?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Enable Azure Files identity-based authentication with Active Directory Domain Services.. Azure Files supports identity-based authentication over SMB using Active Directory Domain Services (AD DS). By enabling this on the storage account, the administrator can mount the file share using existing domain credentials instead of a storage account key, provided the client VM is domain-joined and the share is configured with appropriate NTFS permissions. This eliminates the need to manage or expose storage account keys.

Answer

Enable blob soft delete and mount the share with a blob container SAS token.

Answer

Enable a service endpoint for Microsoft.Storage on the subnet.

Answer

Create a shared access signature for the file share and map it as a local drive.

Question 2

VM-App01 is responding slowly and appears to be on a degraded Azure host. You must keep the VM resource, keep its disks and NIC, and move it to fresh infrastructure before further troubleshooting. Which two actions can achieve that goal? Select two.

Accepted Answer

Redeploy the VM.. Redeploying the VM (Option A) moves the VM to a new Azure host node while preserving the VM resource, its disks, and NIC. This is the correct action because it resolves host-level degradation without deleting or recreating the VM. Stopping/deallocating the VM (Option D) releases the underlying hardware lease, which forces the VM to be placed on a new host when started again, also preserving the VM resource, disks, and NIC.

Answer

Delete the VM and recreate it from the OS disk.

Answer

Capture the VM into a generalized image.

Answer

Convert the VM to an availability set.

Question 3

A security team needs to grant and remove RBAC access for a set of operators on resources in one resource group, but those operators must not create, modify, or delete the resources themselves. Which built-in role should be assigned?

Accepted Answer

User Access Administrator at the resource group scope.. The User Access Administrator role at the resource group scope grants the ability to manage RBAC role assignments for other users on resources within that resource group, but it does not grant permissions to create, modify, or delete the resources themselves. This meets the security team's requirement to grant and remove access without allowing resource management.

Answer

Reader, because it is the most restrictive role available.

Answer

Contributor, because it can manage resources and role assignments together.

Answer

Tag Contributor, because role management and tagging are both governance tasks.

Question 4

A contractor needs to upload data into one specific blob container for six hours. The administrator must avoid sharing the storage account key and should grant only the minimum permissions needed. Which access method should be used?

Accepted Answer

A service SAS scoped to the container with write permission and an expiry time in six hours.. A service SAS scoped to the container with write permission and an expiry time of six hours is correct because it provides time-limited, delegated access to a specific blob container without exposing the storage account key. This meets the requirement of granting only the minimum permissions needed (write) for the six-hour duration, and the SAS can be revoked by regenerating the storage account key if necessary.

Answer

The storage account access key, because it is easier to revoke later.

Answer

A shared key rotation policy, because it grants time-limited access to one container.

Answer

A user-assigned managed identity assigned to the contractor’s laptop.

Question 5

A container group runs a one-time import task and should stop after the task completes successfully. Which restart policy should you use?

Accepted Answer

Never. The 'Never' restart policy is correct because the container group is designed to run a one-time import task and should stop after successful completion. In Azure Container Instances (ACI), the 'Never' policy ensures the container runs exactly once and does not restart, regardless of the exit code. This is ideal for batch jobs or import tasks that should not be retried automatically.

Answer

Always

Answer

OnFailure

Answer

Manual

Question 6

An operations team wants to label resources by Department and Environment so they can search and report on ownership across many resource groups. Which two statements are correct? Select two.

Accepted Answer

Tags are key-value pairs that can be applied to resources and resource groups.. Azure tags are indeed key-value pairs that can be applied to resources and resource groups. This allows the operations team to label resources with metadata like Department and Environment, enabling efficient searching, filtering, and reporting across multiple resource groups without affecting resource functionality.

Answer

A ReadOnly lock is the best way to record department ownership.

Answer

Tags automatically encrypt the data in a resource.

Answer

Tags replace Azure Policy when compliance must be enforced.

Question 7

A platform team has a hardened Windows Server VM that was generalized after patching, agent installation, and baseline configuration. They must deploy the same build to development, test, and production subscriptions, and they want a controlled way to publish newer versions later without rebuilding the image each time. What should they create first?

Accepted Answer

An Azure Compute Gallery image version based on the generalized VM image.. An Azure Compute Gallery (formerly Shared Image Gallery) allows you to store and manage multiple versions of a generalized VM image, enabling controlled, incremental publishing of image updates across subscriptions. By creating an image version in a gallery, the team can deploy the same build to dev, test, and prod subscriptions while maintaining versioning and replication control, avoiding the need to rebuild the image from scratch for each update.

Answer

An availability set for the source VM so new virtual machines inherit the same configuration.

Answer

A managed disk snapshot of the OS disk so new VMs can be created from the captured state.

Answer

A proximity placement group so all future VMs land close to the current server.

Question 8

A web tier and an app tier run in separate subnets. Each VM NIC is placed in an application security group named WebASG or AppASG. The administrator must allow only the web tier to reach the app tier on TCP port 8443 and block all other inbound traffic to the app tier. Which NSG rule should be created on the app subnet?

Accepted Answer

Allow TCP 8443 from WebASG to AppASG with a priority lower number than the deny rule.. NSG rules are evaluated in priority order, with lower numbers having higher priority. By placing an Allow rule for TCP 8443 from WebASG to AppASG with a lower priority number than a subsequent Deny-All rule, only traffic from the web tier is permitted, and all other inbound traffic to the app subnet is blocked. This leverages application security groups (ASGs) to define fine-grained, role-based network security policies without relying on IP addresses.

Answer

Allow TCP 8443 from the entire virtual network to the app subnet with a lower priority than the deny rule.

Answer

Allow UDP 8443 from WebASG to AppASG with any priority below 65000.

Answer

Allow TCP 8443 from WebASG to AppASG with a priority higher number than the deny rule.

Question 9

A new Windows VM must be deployed with an application installed, a configuration file copied from a storage account, and a bootstrap script run automatically after the operating system is provisioned. The operations team does not want to log in manually after deployment. What should they use?

Accepted Answer

A Custom Script Extension attached to the VM during provisioning.. The Custom Script Extension (CSE) is the correct choice because it allows you to run a PowerShell or Bash script automatically after the VM is provisioned. This script can install applications, download configuration files from Azure Storage using a managed identity or SAS token, and execute bootstrap commands—all without any manual login. CSE is the standard Azure mechanism for post-deployment configuration automation on both Windows and Linux VMs.

Answer

Azure Bastion to connect through the browser and complete setup interactively.

Answer

A managed identity assigned to the VM without any extensions.

Answer

An availability set so the VM comes online faster during provisioning.

Question 10

A hub-and-spoke environment uses a DNS server VM in the hub VNet at 10.8.0.4 to resolve internal names such as app01.corp.local. The spoke VNet can reach hub VMs by IP after peering, but name resolution still fails from the spoke. What should the administrator configure so VMs in the spoke use the hub DNS server?

Accepted Answer

Configure the spoke VNet to use 10.8.0.4 as a custom DNS server.. In Azure, a spoke VNet must explicitly be configured with a custom DNS server address to use a non-default DNS resolver. By setting the spoke VNet's DNS server to 10.8.0.4, all VMs in the spoke will send their DNS queries to that hub VM, resolving internal names like app01.corp.local. Without this configuration, the spoke VNet uses Azure-provided DNS, which cannot resolve custom private DNS zones hosted on the hub VM.

Answer

Add an inbound NSG rule on the spoke subnet to allow UDP and TCP 53 to 10.8.0.4.

Answer

Create a service endpoint for Microsoft.Storage on the spoke subnet.

Answer

Add a user-defined route for 10.8.0.4/32 pointing to the virtual network gateway.

Question 11

A platform team must deploy the same group of Azure VMs every month from source control and wants the deployment to be repeatable and reviewable. Which approach should they use?

Accepted Answer

A Bicep template in source control. Bicep is a domain-specific language (DSL) for deploying Azure resources declaratively. Storing a Bicep template in source control ensures the VM deployment is repeatable (same parameters produce identical infrastructure) and reviewable (changes are tracked via pull requests and commit history), meeting the team's requirements for infrastructure as code (IaC).

Answer

Manual portal deployment each month

Answer

A temporary virtual machine snapshot

Answer

A network security group rule collection

Question 12

An administrator needs two non-overlapping VNets in the same region to communicate directly over private IP addresses without deploying a gateway. What should be configured?

Accepted Answer

VNet peering between the two virtual networks.. VNet peering enables direct connectivity between two Azure virtual networks using private IP addresses across the Microsoft backbone, without requiring a gateway or public internet. It supports non-overlapping address spaces in the same region and provides low-latency, high-bandwidth communication. This matches the requirement exactly.

Answer

A site-to-site VPN gateway connection.

Answer

A service endpoint on both subnets.

Answer

A route table with default routes to each VNet.

Question 13

The operations team wants 3 to 8 identical Linux VM instances, with more instances added when average CPU stays above 70 percent for 10 minutes and removed when load falls. Which three settings should be configured? Select three.

Accepted Answer

Use a virtual machine scale set for the identical application instances.. A virtual machine scale set (VMSS) is the correct Azure service for deploying and managing a group of identical, load-balanced Linux VMs that can automatically scale in and out based on demand. It supports autoscaling rules that adjust the instance count within a defined range, meeting the requirement for 3 to 8 identical instances with automatic addition when average CPU exceeds 70% for 10 minutes and removal when load falls.

Answer

Place the VMs in an availability set instead of using a scale set.

Answer

Clone the VM manually whenever CPU rises and remove clones by hand later.

Question 14

Based on the exhibit, where should you assign the Reader role so the Auditors group can read every current and future resource in the Sales subscription, including resource groups created later, while not granting access to the Research subscription?

Accepted Answer

Assign Reader to the Sales subscription, because subscription-level scope includes all current and future resource groups and resources in that subscription.. Assigning the Reader role at the Sales subscription scope grants the Auditors group read access to all current and future resource groups and resources within that subscription. This is because Azure RBAC roles assigned at a subscription level are inherited by all child resource groups and resources, including those created later. The requirement explicitly excludes the Research subscription, so a subscription-level assignment is the correct and most efficient approach.

Answer

Assign Reader to RG-Web, because the group can then inherit access to resources in that resource group only.

Answer

Assign Reader to the Corp management group, because that is the only scope that can cover multiple subscriptions.

Answer

Assign Reader to each resource individually, because that avoids inheritance and limits visibility to selected items.

Question 15

A contractor needs temporary access to upload and download files in only one blob container for 8 hours. You do not want to share the storage account key, and you want to revoke access later without affecting other containers. What should you create?

Accepted Answer

A container-level SAS token backed by a stored access policy, so you can limit and revoke access.. A container-level SAS token backed by a stored access policy is the correct solution because it allows you to grant temporary, scoped access to a single blob container without exposing the storage account key. The stored access policy enables you to revoke the SAS token at any time by modifying or deleting the policy, which immediately invalidates all tokens associated with it, without affecting other containers.

Answer

A storage account access key, because it can be limited to one container by policy.

Answer

Anonymous public access on the container, because it is the easiest way to time-limit access.

Answer

Azure RBAC on the storage account only, because RBAC automatically expires after a few hours.

Question 16

A web app running in Azure App Service must upload images to a blob container without storing any account keys, passwords, or connection strings in configuration. The app uses only one Azure resource. What should the administrator configure?

Accepted Answer

A system-assigned managed identity on the App Service and an Azure RBAC role on the storage account.. A system-assigned managed identity allows the App Service to authenticate to Azure Storage without storing any credentials in configuration. By assigning the RBAC role (e.g., Storage Blob Data Contributor) to that identity, the app can securely upload images using Azure AD authentication, meeting the requirement of no account keys, passwords, or connection strings.

Answer

The storage account key, because it is the simplest way to authenticate an application securely.

Answer

A shared access signature embedded in the app settings, because SAS is the same as managed identity.

Answer

An anonymous public container with write access disabled on the account.

Question 17

Why is centralized logging especially useful during security investigations?

Accepted Answer

It makes related events from multiple devices easier to review and correlate.. Centralized logging aggregates logs from multiple sources (e.g., firewalls, servers, Azure Network Watcher) into a single repository, such as Azure Log Analytics. During security investigations, this enables security analysts to correlate events across devices (e.g., matching a suspicious IP address in firewall logs with authentication failures in domain controller logs) without manually connecting to each device. This correlation is critical for reconstructing attack timelines and identifying lateral movement, which is impossible with siloed logs.

Answer

It guarantees that attacks cannot succeed.

Answer

It replaces the need for authentication and authorization.

Answer

It forces all devices to use the same VLAN.

Question 18

A company has a virtual machine in a subnet that must access an Azure Storage account. The storage account should remain reachable through its public endpoint, but access must be limited to that subnet, and the traffic should stay on the Azure backbone rather than the internet. Which feature should the administrator configure on the subnet?

Accepted Answer

A service endpoint for Microsoft.Storage.. A service endpoint for Microsoft.Storage extends the virtual network identity to the storage account, allowing traffic from the subnet to the storage account's public endpoint to be routed over the Azure backbone network rather than the internet. This satisfies the requirement to limit access to the subnet while keeping the public endpoint reachable and traffic within Azure's infrastructure.

Answer

A private endpoint for the storage account.

Answer

A site-to-site VPN connection to the storage account.

Answer

An application security group assigned to the storage account.

Question 19

An app running on an Azure VM must access Azure SQL Database over a private IP inside the VNet. The team also wants the SQL server name to resolve to that private address without using custom host-file entries. What should be configured?

Accepted Answer

A private endpoint for Azure SQL Database and a linked private DNS zone.. A private endpoint assigns Azure SQL Database a private IP address from the VM's VNet, enabling traffic to stay within Microsoft's backbone. Linking a private DNS zone automatically resolves the SQL server's FQDN (e.g., server.database.windows.net) to that private IP, eliminating the need for custom host-file entries. This meets both requirements: private IP connectivity and DNS resolution without manual configuration.

Answer

A service endpoint on the VM subnet and a firewall rule on Azure SQL Database.

Answer

A public IP address on the VM and a SQL server firewall exception.

Answer

An NSG rule that allows outbound TCP 1433 to the SQL server.

Question 20

A VM in a virtual network must access an Azure Storage account over a private IP address, and the storage account's public endpoint must be disabled. Name resolution from the VM should resolve the storage name to the private IP. Which configuration should you use?

Accepted Answer

Private endpoint with a private DNS zone linked to the virtual network.. A private endpoint assigns a private IP from the virtual network to the storage account, effectively bringing the service into the VNet. By linking a private DNS zone to the virtual network, the VM's DNS resolution for the storage account name returns the private IP instead of the public endpoint, satisfying both the private connectivity and public endpoint disablement requirements.

Answer

Service endpoint on the subnet plus public DNS, because the storage account will expose a private IP automatically.

Answer

Network security group rules only, because they can force traffic to use private addressing.

Answer

Storage account firewall rules with Allow trusted Microsoft services, because that gives a private address path.
