AZ-104 Practice Test 6 — 10 Questions

Question 1

A container group must run an image from a private Azure Container Registry without embedding registry credentials in the deployment. The same authentication method should be reusable by future container groups, and the application must continue to work if the container group is recreated. Which identity approach should the administrator use?

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

Accepted Answer

A user-assigned managed identity assigned to the container group.. A user-assigned managed identity (B) is the correct approach because it is a persistent Microsoft Entra ID identity that can be pre-created and assigned to any number of container groups. It decouples the identity from the container group's lifecycle, so if the container group is recreated, the same identity can be reassigned without reconfiguration. The container group uses this identity to authenticate to ACR via Microsoft Entra ID token-based authentication, eliminating the need to embed registry credentials.

Answer

A system-assigned managed identity for the container group.

Answer

An ACR admin username and password stored in the container image.

Answer

A shared access signature token passed as an environment variable.

Question 2

Three application VMs in separate resource groups must use the same identity to read a configuration endpoint. The identity must keep working if any one VM is deleted and later recreated. Which three actions should the administrator take? Select three.

Accepted Answer

Create a user-assigned managed identity that can exist independently of any single VM.. A user-assigned managed identity is an Azure resource that exists independently of any VM, unlike a system-assigned identity which is tied to the VM lifecycle. This independence ensures the identity persists even when a VM is deleted and recreated, maintaining continuous access to the configuration endpoint. By creating a user-assigned managed identity, the administrator decouples the identity from any single VM, satisfying the requirement that the identity must keep working after VM deletion and recreation.

Answer

Use a system-assigned managed identity on only one VM and copy its access token to the other two VMs.

Answer

Store one application password locally on each VM and use it instead of Azure-managed identities.

Question 3

Based on the exhibit, the business wants two Azure VMs to stay available if a host is patched or fails. A full datacenter outage is not part of the requirement. What should you use?

Accepted Answer

Deploy the VMs in an availability set.. An availability set protects against failures within a single datacenter by distributing VMs across multiple fault domains (physical racks with separate power and network) and update domains (groups that are patched sequentially). This ensures that during host patching or a host failure, at least one VM remains available, meeting the requirement without needing to survive a full datacenter outage.

Answer

Deploy the VMs in the same availability zone.

Answer

Use a virtual machine scale set with autoscale only.

Answer

Place both VMs on a dedicated host.

Question 4

The platform team wants to block deployment of virtual machines that use any size except a small approved list. Operators already have Contributor access and should keep that access for other tasks. Which Azure control should the administrator use to enforce the size restriction?

Accepted Answer

Assign an Azure Policy with an allowed virtual machine size rule and the Deny effect at the subscription scope.. Azure Policy with the 'allowed virtual machine sizes' built-in policy and the Deny effect is the correct control because it enforces a deny action at the resource creation or update level, preventing any VM deployment that does not match the approved size list. This works independently of RBAC permissions, so operators retain their Contributor role for other tasks while the policy blocks non-compliant VM sizes. The policy is assigned at the subscription scope to cover all resource groups, ensuring consistent enforcement across the environment.

Answer

Create a custom RBAC role that excludes unsupported VM sizes from the Contributor role.

Answer

Apply a CanNotDelete lock to the resource group that contains the virtual machines.

Answer

Assign Reader permissions to the operators and rely on Azure portal validation.

Question 5

The team already exports subscription activity logs to a Log Analytics workspace and wants an alert that can ignore delete operations performed by a known automation account. What should they create?

Accepted Answer

A scheduled query alert in Log Analytics using the AzureActivity table. A scheduled query alert in Log Analytics can query the AzureActivity table to filter out delete operations performed by a specific automation account. This allows the alert to ignore those operations by excluding them in the query logic, which is not possible with activity log alerts that lack such granular filtering.

Answer

An activity log alert at the subscription scope

Answer

A metric alert on the subscription

Answer

A diagnostic setting on the resource group

Question 6

Your company has two subscriptions named Dev-Sub and Prod-Sub. A new administrator must be able to create resource groups only in Dev-Sub and must not have any permissions in Prod-Sub. What should you do?

Accepted Answer

Assign Contributor to the administrator at the Dev-Sub scope.. Assigning the Contributor role at the Dev-Sub scope grants the administrator full permissions to create and manage resource groups within that subscription, while the role assignment is scoped exclusively to Dev-Sub, ensuring no permissions in Prod-Sub. Azure RBAC is hierarchical, so a role assigned at a subscription scope applies to all resource groups within it, but does not cross subscription boundaries. This meets the requirement of allowing resource group creation only in Dev-Sub with no access to Prod-Sub.

Answer

Assign Contributor to the administrator at the management group scope.

Answer

Assign Owner to the administrator at the resource group scope in Dev-Sub.

Answer

Assign Reader to the administrator at the Prod-Sub scope and Contributor at the tenant root group.

Question 7

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?

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 8

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 9

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 10

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.
