AZ-104 Deploy and Manage Azure Compute Practice Test 8 — 15 Questions

Question 1

An application uses two Azure VMs in the same datacenter and must continue through planned maintenance and a single hardware host failure. The administrator does not need separate datacenter protection. Which option should be used?

Accepted Answer

Availability set. An availability set distributes VMs across multiple fault domains (hardware hosts) and update domains within a single Azure datacenter. This ensures that during planned maintenance (update domains) or a single hardware host failure (fault domains), at least one VM remains available. Since the requirement does not include separate datacenter protection, an availability set is the correct choice.

Answer

Availability zones

Answer

Proximity placement group

Answer

Virtual machine scale set

Question 2

A company is deploying two Linux application VMs in Azure for a production workload. The region supports availability zones, and the business requires the workload to stay online if an entire datacenter in the region becomes unavailable. Which deployment choice best meets this requirement?

Accepted Answer

Deploy the VMs across two availability zones in the same region.. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Deploying the two Linux VMs across two different zones ensures that if an entire datacenter fails, the VM in the other zone remains online, meeting the requirement for resilience against a full datacenter outage.

Answer

Place both VMs in the same availability set so Azure separates them across update domains.

Answer

Use a single larger VM size with premium SSD storage for better uptime.

Answer

Deploy the VMs in the same resource group and enable auto-shutdown.

Question 3

A container group runs a one-time import job in Azure Container Instances. After the job finishes successfully, it should not restart. Which restart policy should you choose?

Accepted Answer

Never. The 'Never' restart policy ensures that the container group does not restart after the job completes, which is ideal for a one-time import job that should run exactly once. Azure Container Instances supports three restart policies: Always, OnFailure, and Never. For a job that must not restart after successful completion, 'Never' is the correct choice because it prevents any automatic restart regardless of the exit code.

Answer

Always

Answer

OnFailure

Answer

Manual

Question 4

A business wants a line-of-business VM workload to keep running if one Azure datacenter in the region goes offline. Which two deployment choices should the administrator use? Select two.

Accepted Answer

Deploy the VMs in different availability zones.. Option A is correct because deploying VMs across different availability zones protects against a single datacenter failure. Each availability zone is a physically separate datacenter within an Azure region, with independent power, cooling, and networking. If one zone goes offline, the VM in the other zone remains operational, ensuring business continuity for the line-of-business workload.

Answer

Place the VMs in the same availability set.

Answer

Use a proximity placement group for the VMs.

Answer

Use a snapshot of the operating system disk.

Question 5

A line-of-business app runs on two VMs in an Azure region that supports availability zones. The business wants protection from a datacenter failure and wants the VMs placed in different physical locations within the region. Which deployment choice should be used?

Accepted Answer

Two availability zones with one VM in each zone. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Placing one VM in each of two zones ensures that if one datacenter fails, the other VM remains available. This directly meets the requirement for protection from a datacenter failure with VMs in different physical locations.

Answer

An availability set with two fault domains

Answer

A proximity placement group for both VMs

Answer

A single larger VM size with Premium SSD

Question 6

Based on the exhibit, what should the administrator do first to restore the missing data disk?

Accepted Answer

Create a managed disk from the snapshot, then attach it to the VM.. The snapshot represents the missing data disk, not the OS disk. To restore it, you must first create a managed disk from the snapshot (using Azure CLI, PowerShell, or portal), then attach that disk to the VM. This preserves the existing VM configuration and applications without redeployment.

Answer

Recreate the VM from the marketplace image and restore applications manually.

Answer

Convert the snapshot directly into an operating system disk and replace the VM.

Answer

Increase the VM size so that Azure automatically recreates the missing disk.

Question 7

Match each Azure VM access feature to the task it supports.

Question 8

Based on the exhibit, what should the administrator do to meet the performance requirement without rebuilding the server?

Accepted Answer

Resize the VM to a larger SKU that provides more vCPU and RAM.. Resizing the VM to a larger SKU with more vCPU and RAM directly addresses the performance requirement by providing additional compute and memory resources to the existing server without requiring a rebuild. This is the correct approach because the VM's current SKU is insufficient for the workload, and Azure allows resizing within the same hardware family or to a compatible series, preserving the OS and application state.

Answer

Attach an additional data disk and move the application binaries to it.

Answer

Redeploy the VM from a different marketplace image.

Answer

Place the VM in an availability set to spread processing across hosts.

Question 9

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 10

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?

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 Azure AD 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 Azure AD 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 11

Based on the exhibit, what should the administrator do next so the VM can use the extra capacity on the resized data disk?

Accepted Answer

Extend the partition or file system inside the VM.. After resizing a managed disk in Azure, the additional capacity is allocated at the Azure platform level but is not automatically available to the operating system. The administrator must extend the partition or file system inside the VM using tools like Diskpart (Windows) or fdisk/resize2fs (Linux) to make the new space usable. This is a standard post-resize step because the OS still sees the original partition boundaries.

Answer

Resize the managed disk again in Azure.

Answer

Detach the disk and attach it to another VM.

Answer

Create a new virtual machine from the disk.

Question 12

A batch container in Azure Container Instances should stop after a successful run and may retry only when the process fails. Which two restart policies are correct for that style of workload? Select two.

Accepted Answer

Never. Option A (Never) is correct because it ensures the container does not restart after a successful run, which aligns with the requirement to stop after completion. Option B (OnFailure) is correct because it allows the container to retry only when the process fails, meeting the condition of restarting solely on failure. In Azure Container Instances, these two restart policies directly support batch workloads that should not restart on success but may retry on failure.

Answer

Always

Answer

Manual

Answer

Scheduled

Question 13

A data disk was accidentally deleted from a VM. You have a snapshot of that disk from before the deletion. What should you create first to restore the data with minimal impact to the VM's OS disk?

Accepted Answer

A new managed disk from the snapshot. A is correct because creating a new managed disk from the snapshot is the direct and minimal-impact method to restore the deleted data disk. Once the new managed disk is created, you can attach it to the existing VM without affecting the OS disk or requiring a VM rebuild. This approach avoids any downtime beyond the brief attachment operation.

Answer

A new virtual machine

Answer

A new availability set

Answer

A larger VM size

Question 14

A data disk was accidentally deleted from a production VM. The team has a snapshot of that disk from the previous night and wants the fastest Azure-side recovery path with the least risk of overwriting the existing OS disk. What should the administrator do first?

Accepted Answer

Create a new managed disk from the snapshot, then attach that disk to the VM.. Option B is correct because creating a new managed disk from the snapshot and attaching it to the VM is the fastest Azure-side recovery path. This approach directly reuses the existing OS disk without any risk of overwriting it, and the new data disk can be attached within minutes using the Azure portal, CLI, or PowerShell. It avoids any downtime for the VM beyond the brief attach operation.

Answer

Restore the entire virtual machine from the snapshot and overwrite the current instance.

Answer

Convert the snapshot into a temporary storage account and copy the files back manually.

Answer

Recreate the VM from the same marketplace image and restore only the deleted disk later.

Question 15

A line-of-business app runs on a single Azure VM in a region that supports availability zones. The business wants the VM to keep running if one datacenter in the region becomes unavailable. Which deployment choice best meets this requirement?

Accepted Answer

Availability zone. An availability zone is a physically separate datacenter within an Azure region, with independent power, cooling, and networking. Deploying the VM to a specific zone ensures it remains operational if another zone's datacenter fails, meeting the requirement for single-VM resilience against a datacenter outage.

Answer

Availability set

Answer

Proximity placement group

Answer

Virtual machine scale set
