AZ-104 Practice Test 2 — 30 Questions

Question 1

A VM suffered corruption and an auditor also needs one missing file. Match each Azure Backup restore workflow to the recovery outcome it provides.

Accepted Answer

Restore VM: Creates a new VM. Azure Backup restore workflows: 'Restore VM' creates a new VM, 'Restore files' recovers individual files, 'Restore as unmanaged/managed disks' recovers disks, 'Replace existing VM' overwrites the original, and 'Cross-region restore' restores to another region.

Answer

Restore VM: Recovers individual files

Answer

Restore files: Overwrites the original VM

Question 2

A company uses Azure Blob Storage for legal documents. The documents must not be modified or deleted for seven years after upload, even by administrators. What should you configure?

Accepted Answer

Immutable blob storage with a time-based retention policy. Immutable blob storage with a time-based retention policy (WORM – Write Once, Read Many) ensures that blobs cannot be modified or deleted for a specified retention period, even by administrators. This is the only Azure storage feature that provides legal hold or regulatory compliance for fixed records, such as legal documents that must remain unaltered for seven years.

Answer

Blob soft delete

Answer

Lifecycle management to move blobs to Archive

Answer

Blob versioning

Question 3

An operations team maintains a hardened Windows Server image with application prerequisites and monitoring tools already installed. They want to deploy future VMs from the same versioned image in multiple subscriptions and promote a new build only after testing. Which Azure feature should they use?

Accepted Answer

An Azure Compute Gallery image version. An Azure Compute Gallery (formerly Shared Image Gallery) allows you to store and manage multiple versions of a custom VM image, replicate them across regions, and share them across subscriptions. This enables the team to maintain a hardened, versioned image, deploy VMs from it in multiple subscriptions, and promote a new build only after testing by creating a new image version.

Answer

A managed disk snapshot created from one of the VMs

Answer

A custom script extension installed during VM provisioning

Answer

An availability set containing the VMs

Question 4

A stateless web application needs a group of identical Azure VMs that can automatically add more instances during the workday and remove them at night based on CPU usage. What should the administrator deploy?

Accepted Answer

A virtual machine scale set with autoscale rules. A virtual machine scale set (VMSS) with autoscale rules is the correct solution because it provides a group of identical, load-balanced VMs that can automatically scale out (add instances) during high CPU usage in the workday and scale in (remove instances) at night based on CPU thresholds. This matches the stateless, elastic requirement perfectly, as VMSS is designed for horizontal scaling of identical instances with autoscale policies tied to metrics like CPU percentage.

Answer

An availability set with two VMs

Answer

A single VM with a larger disk

Answer

An Azure Policy assignment to increase CPU capacity

Question 5

A web tier and an app tier run on separate Azure VMs in the same region. Each VM's NIC is added to an application security group named WebASG or AppASG. The administrator must allow only the web tier to connect to the app tier on TCP 8443, and future VM scale-outs must be included automatically. Which NSG rule should be created?

Accepted Answer

An inbound rule with source WebASG, destination AppASG, protocol TCP, and destination port 8443.. Application security groups (ASGs) allow you to configure network security as a natural extension of an application's structure, enabling you to group VMs by their roles (e.g., web tier, app tier) and define rules based on those groups. By creating an inbound NSG rule with source WebASG and destination AppASG on TCP port 8443, any VM added to WebASG can initiate traffic to any VM in AppASG, and future scale-outs are automatically included without manual IP updates. This approach is dynamic, scalable, and aligns with the requirement for automatic inclusion of new VMs.

Answer

An inbound rule that uses the current web VM's private IP as the source and the current app VM's private IP as the destination.

Answer

A route table that sends TCP 8443 traffic from the web subnet to the app subnet.

Answer

An Azure Firewall application rule collection that permits all traffic between the two subnets.

Question 6

A legal department stores project video assets in Azure Blob Storage. The files are reviewed only during quarterly audits, but when someone needs a file it must open immediately without waiting for rehydration. Which access tier should the administrator use for the blobs?

Accepted Answer

Cool, because it is for infrequent access while still keeping blobs online and immediately available.. The Cool access tier is designed for data that is infrequently accessed but must remain immediately available (online) without any rehydration delay. Since the legal department needs instant access during quarterly audits, Cool meets the requirement of low retrieval cost while keeping blobs online, unlike Archive which requires hours-long rehydration.

Answer

Hot, because it is optimized for frequent access and always costs the least to retrieve.

Answer

Archive, because it is the cheapest choice for data that is rarely used and can be restored instantly.

Answer

Premium, because it is intended for workload bursts and gives the best long-term storage economics.

Question 7

You need an alert that emails administrators when CPU on VM-DB01 exceeds a threshold. Which two Azure Monitor components work together to achieve this?

Accepted Answer

A metric alert and an action group. A metric alert monitors a specific performance metric (like CPU percentage) on a target resource (VM-DB01) and triggers when the value crosses a defined threshold. An action group defines the notification actions (e.g., sending an email to administrators) that execute when the alert fires. Together, they form the core alerting workflow in Azure Monitor: the metric alert evaluates the condition, and the action group delivers the response.

Answer

A budget alert and a private DNS zone

Answer

A Recovery Services vault and a route table

Answer

An activity log export and a lock

Question 8

A media archive stores large video files that must survive a zone failure in the primary region and also be replicated to a paired region for disaster recovery. The archive team does not want anyone to read from the secondary region during normal operations, and cost should be lower than the read-access variant. Which redundancy option should you configure?

Accepted Answer

GZRS, because it adds zone redundancy and geo-replication without enabling secondary read access.. GZRS (Geo-Zone-Redundant Storage) is correct because it combines zone redundancy (three copies across availability zones in the primary region) with geo-replication to a paired secondary region, but crucially does not enable read access to the secondary region by default. This satisfies the requirement to survive a zone failure, provide disaster recovery to a paired region, and prevent reads from the secondary during normal operations, all at a lower cost than RA-GRS which includes secondary read access.

Answer

LRS, because it keeps copies in a single datacenter and is the lowest-cost option.

Answer

ZRS, because it protects against zone failures but not regional outages.

Answer

RA-GRS, because the read-access copy is needed whenever data is replicated to another region.

Question 9

A storage account must stay online for applications, but administrators have a temporary freeze on configuration changes. Users can still view the account, but attempts to change the access tier, create a container, or update networking all fail. What most likely caused the behavior?

Accepted Answer

A ReadOnly lock was applied to the storage account.. A ReadOnly lock (Azure Resource Manager lock) prevents any modification to the storage account, including changing the access tier, creating containers, or updating networking settings, while still allowing read operations like viewing the account. This matches the described behavior exactly because the lock is applied at the resource scope and blocks all write/delete operations, but does not affect read access.

Answer

A CanNotDelete lock was applied to the storage account.

Answer

An Azure Policy audit assignment was applied to the storage account.

Answer

The account was moved to a different subscription.

Question 10

An administrator wants to let a help desk group start, stop, and restart virtual machines in one resource group, but the group must not be able to delete the VMs or any other resource in the group. Which two actions should the administrator take? Select two.

Accepted Answer

Create a custom RBAC role with only VM start, stop, restart, and read actions.. Option A is correct because Azure RBAC's built-in Virtual Machine Contributor role also grants delete permissions, so the administrator must create a custom role scoped to only the required actions, such as Microsoft.Compute/virtualMachines/start/action, powerOff/action, restart/action, and read. Option B is correct because assigning that custom role at the resource group scope grants the help desk group the needed permissions on all VMs in that group while keeping the role limited to that boundary. Option C is incorrect because Virtual Machine Contributor includes Microsoft.Compute/virtualMachines/delete, which violates the requirement that the group must not delete VMs. Option D is incorrect because a CanNotDelete lock prevents deletion for everyone, including administrators, and does not grant start/stop/restart permissions. Option E is incorrect because Azure Policy can deny deletion but does not grant the start, stop, and restart permissions the help desk group needs.

Answer

Assign Virtual Machine Contributor to the help desk group.

Answer

Apply a CanNotDelete lock to the resource group.

Answer

Use Azure Policy to block VM deletion and leave RBAC unchanged.

Question 11

Order the steps to set up Azure Site Recovery for on-premises to Azure.

Accepted Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Install the Mobility service agent on on-premises machines, Step 4: Enable replication, Step 5: Test failover. The correct sequence for setting up Azure Site Recovery for on-premises to Azure is: create a Recovery Services vault, configure source and target settings, install the Mobility service agent on on-premises machines, enable replication, and then test failover. This order ensures prerequisites are met and replication is active before testing.

Answer

Step 1: Install the Mobility service agent on on-premises machines, Step 2: Create a Recovery Services vault, Step 3: Configure source and target settings, Step 4: Enable replication, Step 5: Test failover

Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Enable replication, Step 4: Install the Mobility service agent on on-premises machines, Step 5: Test failover

Answer

Step 1: Create a Recovery Services vault, Step 2: Configure source and target settings, Step 3: Install the Mobility service agent on on-premises machines, Step 4: Test failover, Step 5: Enable replication

Question 12

Arrange the steps to create an Azure Storage account with a container and upload a blob.

Accepted Answer

Create storage account → Create container → Set access level → Upload blob → Generate SAS. Create storage account, create container, set access, upload blob, generate SAS.

Answer

Create container → Create storage account → Set access level → Upload blob → Generate SAS

Answer

Create storage account → Upload blob → Create container → Set access level → Generate SAS

Answer

Create storage account → Create container → Upload blob → Set access level → Generate SAS

Question 13

Based on the exhibit, what should the administrator do so VM-B resolves the storage account name to the private IP address?

Accepted Answer

Link the private DNS zone to VNet-B.. The private DNS zone for the storage account must be linked to VNet-B so that VM-B can resolve the storage account's fully qualified domain name (FQDN) to the private IP address of the private endpoint. Without this link, the DNS resolution will fall back to the public endpoint, bypassing the private connectivity. Linking the zone ensures Azure's default DNS servers return the private IP for the storage account within VNet-B.

Answer

Create a service endpoint on VNet-B and leave DNS unchanged.

Answer

Assign a public IP address to the private endpoint.

Answer

Add a route table with a next hop to the storage account.

Question 14

Based on the exhibit, a policy assigned at the subscription denies storage accounts that allow public network access. One existing storage account in RG-Legacy must remain publicly reachable for 30 days while a migration is completed. What should the administrator use?

Accepted Answer

Create a policy exemption for stlegacy01 at the resource scope.. A policy exemption at the resource scope is the correct approach because it allows the administrator to selectively exclude the specific storage account (stlegacy01) from the subscription-level policy that denies public network access. This exemption can be configured with an expiration date of 30 days, ensuring the legacy account remains publicly reachable during the migration while the policy continues to apply to all other resources. Policy exemptions are designed for exactly this scenario—temporary exceptions for compliance or migration needs—without altering the policy definition or assignment.

Answer

Remove the policy assignment from the subscription until the migration finishes.

Answer

Change the policy effect from Deny to Audit.

Answer

Move the legacy storage account to a separate subscription and assign the policy there.

Question 15

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 16

A contractor must import data into one blob container for six hours. The contractor should not receive the storage account key, and access must be limited to that container only. Which credential should the administrator generate?

Accepted Answer

A user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.. A user delegation SAS is signed with Microsoft Entra credentials (formerly Azure AD) and can be scoped to a specific blob container with a time limit. This meets the requirement of granting the contractor access only to that container for six hours without exposing the storage account key.

Answer

A storage account access key, because it can be copied into the import tool.

Answer

A shared key connection string, because it works with any tool that needs blob access.

Answer

A managed identity token, because the contractor can use it outside Azure directly.

Question 17

A customer wants official information about whether an Azure service issue is affecting their subscription or the wider Azure platform. Which two sources should they check? Select two.

Accepted Answer

Azure Service Health. Azure Service Health (B) provides personalized alerts and guidance when Azure service issues affect your subscription, including planned maintenance and health advisories. Azure Status (D) offers a global view of the health of all Azure services across regions, which is the official source for widespread platform issues. Together, they cover both subscription-specific and platform-wide service incidents.

Question 18

A finance application is deployed in a single resource group named rg-finance-app. The team must manage only the resources in that group and must not receive permissions for other resource groups in the subscription. Where should the Contributor role be assigned?

Accepted Answer

At the rg-finance-app resource group scope.. The Contributor role must be assigned at the rg-finance-app resource group scope to restrict permissions exclusively to that group. This ensures the team can manage only the resources within that resource group, without inheriting permissions to other resource groups in the subscription. Role assignments in Azure are inherited from higher scopes (management group, subscription) down to lower scopes, so assigning at the resource group scope is the most specific and restrictive level that meets the requirement.

Answer

At the management group that contains the subscription.

Answer

At the subscription scope.

Answer

At each individual resource in the resource group.

Question 19

A company wants to peer a new spoke virtual network to an existing hub VNet. The hub uses 10.40.0.0/16, and the new spoke was created with 10.40.128.0/17 because that range seemed available in the branch office plan. Peering creation fails. What should the administrator do?

Accepted Answer

Change the spoke VNet to a non-overlapping address space before peering.. VNet peering requires that the address spaces of the peered virtual networks do not overlap. The hub uses 10.40.0.0/16, and the spoke uses 10.40.128.0/17, which is a subset of the hub’s range. Azure blocks peering when there is any overlap to prevent routing conflicts. The correct fix is to change the spoke VNet to a non-overlapping address space, such as a different RFC 1918 range like 10.1.0.0/16, before attempting to peer.

Answer

Add a second address prefix to the spoke VNet and keep the overlapping range.

Answer

Enable gateway transit on the hub VNet before retrying peering.

Answer

Create custom DNS records for the spoke VNet so the address ranges no longer conflict.

Question 20

Before changing a production VM's data disk, you want a point-in-time copy that can be restored later without affecting the VM. What should you create?

Accepted Answer

Snapshot. A snapshot captures a point-in-time, read-only copy of a managed or unmanaged disk. It can be used to create a new disk or restore the original disk without affecting the running VM, making it the correct choice for a non-disruptive backup before a data disk change.

Answer

Availability set

Answer

Azure Policy assignment

Answer

Virtual network peering
