AZ-104 Deploy and Manage Azure Compute Practice Test 5 — 15 Questions

Question 1

Based on the exhibit, the company will deploy two identical web server VMs in East US 2 behind a load balancer. The service must keep running if one datacenter in the region becomes unavailable. Which deployment choice best meets the requirement?

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

Accepted Answer

Place one VM in each of two availability zones and front them with the load balancer.. Deploying one VM in each of two availability zones within East US 2 ensures that the VMs are physically separated across distinct datacenters, each with independent power, cooling, and networking. If one datacenter (zone) fails, the other zone remains operational, and the load balancer automatically directs traffic to the healthy VM. This meets the requirement of keeping the service running if one datacenter in the region becomes unavailable.

Answer

Place both VMs in an availability set so Azure can spread them across fault domains.

Answer

Place both VMs in one availability zone because all zones in a region share failure domains.

Answer

Deploy a single VM because Azure automatically replicates it across the region.

Question 2

A stateless web app runs on two Ubuntu VMs behind an Azure Load Balancer. The region supports availability zones. The business wants the app to survive a full datacenter outage and also avoid having both VMs on the same maintenance boundary. Which deployment should you choose?

Accepted Answer

Place the VMs in separate availability zones in the same region.. Deploying the VMs in separate availability zones ensures they are placed in physically distinct datacenters within the same region, protecting against a full datacenter outage. Additionally, each availability zone has its own fault and update domains, so the VMs will never share the same maintenance boundary, meeting both business requirements.

Answer

Place both VMs in a single availability set.

Answer

Deploy one VM and rely on Azure Backup for recovery.

Answer

Deploy both VMs without any fault-domain configuration.

Question 3

Match each Azure CLI command to the action it performs for a virtual machine.

Accepted Answer

az vm create: Creates a new virtual machine.. Each Azure CLI command performs the corresponding VM lifecycle action: create, start, stop, deallocate (releases resources), delete, or list.

Answer

az vm start: Stops a running virtual machine.

Answer

az vm stop: Deallocates a virtual machine.

Question 4

Match each Azure VM administration requirement on the left with the most appropriate Azure CLI command on the right. Use each answer once.

Accepted Answer

Deploy a new virtual machine: az vm create. Azure CLI commands for VM administration: 'az vm create' deploys, 'az vm resize' changes size, 'az vm start/stop/restart' controls state, and 'az vm delete' removes the VM.

Answer

Stop a virtual machine: az vm delete

Answer

Delete a virtual machine: az vm restart

Answer

Restart a virtual machine: az vm stop

Question 5

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 6

A customer-facing service needs to survive a single datacenter outage in a zone-supported region. You do not need cross-region failover, but you do need Azure to spread instances without manual placement errors. Which two deployment choices satisfy that goal? Select two.

Accepted Answer

Place the VMs in different availability zones within the same region.. Availability zones are physically separate datacenters within a region, each with independent power, cooling, and networking. Placing VMs in different zones ensures that a single datacenter outage does not affect all instances, meeting the survivability requirement without manual placement errors. Azure automatically distributes VMs across selected zones, eliminating human error in instance placement.

Answer

Use an availability set and expect it to cover a zone outage.

Answer

Keep all instances in one zone and rely on the load balancer.

Answer

Use a paired region for automatic in-region zone balancing.

Question 7

A build agent VM is recreated from image every night. The OS can be lost on reimage, but build caches and artifacts must persist across rebuilds. The team also wants the cheapest OS storage option that supports this pattern. Which two choices should you make? Select two.

Accepted Answer

Use an ephemeral OS disk.. An ephemeral OS disk uses the local VM storage or temp SSD, which is destroyed when the VM is deallocated or reimaged. This matches the requirement that the OS can be lost on reimage. Option B is correct because placing build caches and artifacts on a separate managed data disk ensures they persist independently of the OS disk lifecycle; data disks are not affected by OS reimaging and can be reattached to the new VM instance.

Answer

Use a Premium SSD OS disk so the reimage is preserved.

Answer

Store the caches only on the temporary resource disk.

Answer

Use an availability set to make the OS disk persistent.

Question 8

An application runs on two identical VMs in a region that does not support availability zones. The app must keep running through planned maintenance and a single hardware fault, and the team does not want to add a second region. Which two deployment choices are appropriate? Select two.

Accepted Answer

Place the VMs in an availability set.. A is correct because an availability set distributes VMs across multiple fault domains (up to 3) and update domains (up to 20) within the same datacenter. This ensures that during planned maintenance (update domain isolation) or a hardware fault (fault domain isolation), at least one VM remains available, meeting the requirement without needing availability zones or a second region.

Answer

Put both VMs in the same fault domain to simplify patching.

Answer

Deploy the workload in availability zones anyway.

Answer

Use a second Azure region for the primary failover design.

Question 9

A reporting server must be resized from 4 vCPU to 8 vCPU for a four-hour batch window. The VM name, NIC, private IP, and attached managed disks must stay the same, and the team accepts a brief outage during the change. Which two actions should you choose? Select two.

Accepted Answer

Deallocate the VM before changing its size.. Deallocating the VM (stopping it in the Azure portal) releases the underlying hardware reservation, which is required before changing the VM size to a different SKU. This ensures the VM can be resized to a supported size without conflicts, and the brief outage is acceptable as stated in the scenario.

Answer

Delete the VM and recreate it with a new size.

Answer

Generalize the VM first to preserve the existing configuration.

Answer

Take a snapshot of the OS disk instead of resizing.

Question 10

A data disk on VM-Data01 was corrupted after a bad patch, and you already have a snapshot taken last night. The OS disk should remain unchanged. Which two actions should you take to restore only the data disk? Select two.

Accepted Answer

Create a managed disk from the snapshot.. A snapshot is a point-in-time copy of a disk that can be used to create a new managed disk. Since you have a snapshot of the corrupted data disk from last night, creating a managed disk from that snapshot restores the data to its state at the time of the snapshot, leaving the OS disk untouched.

Answer

Redeploy the VM and expect the data disk to revert automatically.

Answer

Generalize the VM and redeploy it from the snapshot.

Answer

Replace the snapshot with the current data disk to roll back the VM.

Question 11

A platform team has a generalized VM image that must be published to East US and West Europe today and patched later without overwriting the original build. They want Azure to keep version history and replicate the image to both regions. Which two actions or resources should they use? Select two.

Accepted Answer

Create an Azure Compute Gallery. Azure Compute Gallery (formerly Shared Image Gallery) allows you to store and manage VM image versions, including version history, and replicate them across multiple Azure regions. By creating an image definition and image version within the gallery, you can publish the generalized VM image to East US and West Europe today, and later create a new image version for patching without overwriting the original build, preserving the version history.

Answer

Capture the VM as a single managed image and copy it manually to each region

Answer

Use an availability set to preserve the image

Answer

Take a snapshot of the OS disk and deploy VMs directly from the snapshot

Question 12

A developer packages an internal web app as a Linux container. The app must be published with built-in HTTPS, deployment slots, and autoscale, and the team does not want to manage OS patching or container hosts. Which Azure service should the administrator choose?

Accepted Answer

Azure App Service. Azure App Service is the correct choice because it natively supports Linux containers, built-in HTTPS via TLS/SSL, deployment slots for staging and production swaps, and autoscale based on metrics or schedules. It also abstracts OS patching and container host management, meeting the team's requirement to avoid managing infrastructure.

Answer

Azure Container Instances

Answer

Azure Virtual Machines

Answer

Azure Kubernetes Service

Question 13

After applying a custom image, a VM boots to a black screen with a blinking cursor. The OS never reaches the login prompt. The administrator needs the fastest way to inspect the boot process and view serial console output. What should be enabled or checked?

Accepted Answer

Boot diagnostics. Boot diagnostics captures serial console output and screenshots of the VM during boot. When a VM boots to a black screen with a blinking cursor, the serial console log provides the exact kernel or bootloader messages (e.g., GRUB, initramfs errors) without requiring OS-level access. This is the fastest way to inspect the boot process because it works even when the OS is unresponsive.

Question 14

A reporting application must run on an Azure VM with at least 8 vCPUs and 64 GiB of RAM. The team also wants headroom for short spikes without falling below the requirement. Which two VM sizes meet or exceed the requirement? Select two.

Accepted Answer

Standard_E8s_v5. Standard_E8s_v5 is correct because it provides 8 vCPUs and 64 GiB of RAM, meeting the minimum requirement exactly. The E-series is memory-optimized, offering a high memory-to-core ratio suitable for reporting workloads, and the v5 generation includes Intel Xeon Platinum 8370C processors with support for premium storage and accelerated networking, ensuring headroom for short spikes without dropping below the requirement.

Answer

Standard_D8s_v5

Answer

Standard_F8s_v2

Answer

Standard_B8ms

Question 15

A build pipeline needs to run a Linux container for 10 to 15 minutes at a time. The team does not want to manage servers, clusters, or an always-on VM. Which Azure service should be used?

Accepted Answer

Azure Container Instances. Azure Container Instances (ACI) is the correct choice because it allows you to run a Linux container directly on Azure without provisioning or managing any underlying infrastructure. ACI is ideal for short-lived, burstable workloads like a build pipeline that runs for 10–15 minutes, as it supports per-second billing and automatic startup/shutdown without the overhead of a cluster or VM.
