AZ-104 Deploy and Manage Azure Compute Practice Test 10 — 15 Questions

Question 1

An administrator wants future VMs to start from the same approved server build as an existing generalized VM. Which two image sources can be used to create the new VM? Select two.

Accepted Answer

A managed image created from the approved server build.. A managed image captures the exact configuration of a generalized VM, including the OS and data disks, and can be used to deploy multiple identical VMs. This ensures that future VMs start from the same approved server build without needing to recreate the image each time.

Answer

A Marketplace image from the operating system vendor.

Answer

A single managed disk snapshot.

Answer

A public IP address assigned to the VM.

Question 2

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 3

Match each Azure VM deployment concept to the description that best fits it.

Question 4

A managed data disk on a VM was deleted by mistake. You have a snapshot from before the deletion and want to restore the data with minimal impact to the VM's operating system disk. What should you do?

Accepted Answer

Create a new managed disk from the snapshot and attach it to the VM. Option A is correct because you can create a new managed disk from the snapshot and attach it as a data disk to the existing VM. This restores the data without affecting the OS disk or requiring a VM redeployment, minimizing downtime and impact.

Answer

Redeploy the VM from the marketplace image

Answer

Convert the snapshot directly into an OS disk and boot from it

Answer

Resize the VM to a larger size and the deleted disk will reappear

Question 5

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 6

An application on an Azure VM has outgrown its current CPU and memory. The administrator wants to increase compute capacity without rebuilding the application or changing the VM image. What should be done?

Accepted Answer

Resize the virtual machine to a larger size. Resizing the VM to a larger size (Option A) directly increases the CPU and memory resources allocated to the VM without requiring any changes to the application or the underlying OS disk image. Azure allows you to change the VM size as long as the new size is available in the current hardware cluster and the VM is deallocated (stopped) first. This is the simplest and most appropriate method to scale up compute capacity while preserving the existing configuration and data.

Answer

Create a new snapshot of the OS disk

Answer

Move the VM to an availability set

Answer

Attach a data disk

Question 7

A container group runs a nightly processing job in Azure Container Instances. The job should exit after completing successfully and should not restart automatically. Which restart policy should you configure?

Accepted Answer

Never. The 'Never' restart policy ensures that the container group runs once and does not restart after it exits, regardless of the exit code. This is ideal for a nightly batch job that should complete and then stop permanently without automatic restarts.

Answer

Always

Answer

OnFailure

Answer

Automatic

Question 8

A line-of-business app will run on a single Azure virtual machine in a region that supports availability zones. The business wants the VM to keep running if one datacenter in the region fails. Which deployment choice should you use?

Accepted Answer

Deploy the VM in an availability zone. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Deploying the VM in an an availability zone ensures that if one datacenter fails, the VM remains operational because it is hosted in a different zone. This directly meets the requirement for resilience against a single datacenter failure.

Answer

Place the VM in an availability set

Answer

Use a larger VM size

Answer

Use a custom image

Question 9

A team has an approved Windows VM that already includes patches, a monitoring agent, and line-of-business software. They want future VMs to start from that same build. What should they use?

Accepted Answer

A custom image. A custom image captures the exact state of a VM, including installed patches, monitoring agents, and line-of-business software, allowing you to create multiple identical VMs from that golden image. Unlike a snapshot, which is tied to a specific disk and requires manual steps to create a VM, a custom image is stored as a managed image resource that can be used directly during VM provisioning via the Azure portal, CLI, or ARM templates.

Answer

A snapshot of the OS disk

Answer

An availability set

Answer

A larger VM size

Question 10

An operations team must administer Windows and Linux VMs that have no public IP addresses. They want to connect from a browser without installing a VPN client and without exposing RDP or SSH to the internet. Which Azure service should they deploy?

Accepted Answer

Azure Bastion. Azure Bastion provides secure, seamless RDP and SSH connectivity to virtual machines directly from the Azure portal over TLS, without requiring a public IP address on the VM, a VPN client, or exposing RDP/SSH ports to the internet. It uses a hardened bastion host inside the virtual network, proxying connections via the browser, which satisfies the requirement for browser-based access without additional client software.

Answer

Azure Load Balancer

Answer

VPN Gateway point-to-site only

Answer

Application Gateway

Question 11

A managed data disk was accidentally deleted from a VM. A snapshot taken the day before is still available. Which two actions should the administrator perform to recover the data? Select two.

Accepted Answer

Create a new managed disk from the snapshot.. Option A is correct because a snapshot is a point-in-time, read-only copy of a managed disk. To recover the data, you must create a new managed disk from the snapshot using the `az disk create --source` command or the Azure portal. This new disk will contain the exact data as it existed when the snapshot was taken.

Answer

Mount the snapshot directly as a data disk.

Answer

Redeploy the VM and reinstall the operating system.

Answer

Delete the snapshot after verifying it exists.

Question 12

You are deploying a new Windows VM and want it to start with the same custom software and configuration that already exist on an approved production VM. What should you use as the source for the new VM?

Accepted Answer

A custom image. A custom image captures the exact OS configuration, installed software, and settings from a source VM, allowing you to deploy new VMs with identical customizations. Unlike a marketplace image, which provides only a generic OS, a custom image preserves all modifications made to the approved production VM, including applications and system tweaks.

Answer

A marketplace image

Answer

A snapshot of the OS disk

Answer

An availability set

Question 13

Based on the exhibit, which deployment change best meets the resilience requirement for the application VMs?

Accepted Answer

Place each VM in a different availability zone and keep the load balancer in front.. Option B is correct because deploying each VM into a different availability zone ensures that the VMs are physically separated across distinct data centers within an Azure region, protecting against zone-level failures. The load balancer in front distributes traffic across the VMs, providing high availability even if one zone goes offline. This meets the resilience requirement by eliminating a single point of failure at the data center level.

Answer

Keep both VMs in the same availability set to spread them across update domains only.

Answer

Deploy both VMs into a proximity placement group to reduce latency between them.

Answer

Move the VMs into a single availability set and add more managed disks for redundancy.

Question 14

Match each image or placement term to the administrator need it supports.

Question 15

Based on the exhibit, which deployment choice should the administrator use to keep the application available if one datacenter in the Azure region fails?

Accepted Answer

Deploy the VMs across separate availability zones.. Availability zones are physically separate datacenters within an Azure region, each with independent power, cooling, and networking. Deploying VMs across separate availability zones ensures that if one datacenter fails, the application remains available in the other zone, providing resilience against datacenter-level failures.

Answer

Place both VMs in the same availability set.

Answer

Use a proximity placement group for both VMs.

Answer

Use a larger VM size for each virtual machine.
