AZ-104 Practice Test 3 — 10 Questions

Question 1

Which three of the following statements about Azure App Service plans are correct? (Choose three.)

Accepted Answer

The Isolated tier provides network isolation and is designed for apps that require high security and scaling.. Apps in the same App Service plan share the same compute resources (VMs, memory, CPU) because the plan defines the underlying infrastructure. This is true even if the apps are in different resource groups, as the plan is the boundary for resource allocation, not the resource group.

Answer

Changing the pricing tier of an App Service plan always causes downtime for all apps in the plan.

Answer

The Free and Shared tiers support custom domain names and SSL binding without additional cost.

Answer

An App Service plan can only contain apps from the same region and the same resource group.

Question 2

Match each lifecycle management requirement to the blob tier transition or action that should be configured.

Accepted Answer

Move blobs not modified for 30 days: Transition to cool tier. Lifecycle management rules define actions (tier changes or deletion) based on age or access. The actions correspond to moving to cooler tiers (cool, cold, archive) or deleting, and can apply to snapshots.

Answer

Move blobs not modified for 30 days: Transition to archive tier

Answer

Move blobs not modified for 90 days: Transition to cool tier

Answer

Delete blobs after 365 days: Transition to cool tier

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 data-access pattern to the blob tier or required action.

Accepted Answer

Frequent read and write operations: Hot tier. Azure Blob Storage tiers are Hot (frequent access), Cool (infrequent, 30-day minimum), and Archive (rare, 180-day minimum). Rehydration is needed to access Archive blobs. Azure Files sync is used for replication.

Answer

Frequent read and write operations: Cool tier

Answer

Infrequent access with 30-day minimum storage duration: Archive tier

Question 5

Match each workload requirement to the Azure storage account kind that best fits it.

Accepted Answer

General-purpose v2: Provides support for blobs, files, queues, tables, and VM disks. Suitable for most general-purpose workloads.. Each storage kind is tailored for specific workloads: GPv2 is the default, BlockBlobStorage for high throughput, FileStorage for premium files, and others for legacy or specialized needs.

Answer

General-purpose v2: Premium performance for block blob and append blob data, with low latency.

Answer

BlockBlobStorage: Legacy blob-only account type.

Question 6

A Windows VM and a Linux VM are both joined to the same Active Directory Domain Services domain. Which two authentication methods can be used to mount the same Azure Files share over SMB? Select two.

Accepted Answer

Storage account key. The storage account key provides administrative access to the Azure Files share, allowing any SMB client (Windows or Linux) to mount the share by using the key as the credential. Option B is correct because when both VMs are joined to the same Active Directory Domain Services domain, the Azure Files share can be enabled for AD DS authentication, allowing domain-joined clients to mount the share using their domain credentials.

Answer

Blob SAS token

Answer

Network security group rule

Answer

Azure resource lock

Question 7

Based on the exhibit, which identity approach should be used so all three virtual machines can reuse the same Azure access without sharing secrets?

Accepted Answer

Use a user-assigned managed identity and attach it to all three VMs.. A user-assigned managed identity is a standalone Azure resource that can be assigned to multiple Azure VMs, allowing all three VMs to authenticate to Azure services (e.g., Azure Storage, Key Vault) using the same identity without sharing any secrets. This approach eliminates the need to manage or rotate credentials, as the identity is managed entirely by Azure AD and tokens are obtained via the Azure Instance Metadata Service (IMDS) endpoint.

Answer

Assign a system-assigned managed identity to each VM.

Answer

Create a storage account access key and place it in each VM's application settings.

Answer

Create a separate SAS token for each VM and rotate it manually.

Question 8

You need to prevent accidental deletion of a resource group while still allowing administrators to create and modify resources inside it. Which Azure lock should you apply?

Accepted Answer

CanNotDelete. The CanNotDelete lock prevents deletion of the resource group while still allowing all operations (read, write, modify) on resources within it. This lock type is designed specifically to protect against accidental deletion without restricting administrative actions like creating or updating resources.

Answer

ReadOnly

Answer

Delete lock

Answer

No lock and a budget alert

Question 9

A media company stores project video assets in Azure Blob Storage. The business requires the data to survive a single availability zone outage in the primary region. In addition, if the primary region becomes unavailable, operations staff must still be able to read the most recently replicated copy from the secondary region right away, even if writes are temporarily unavailable. Which redundancy option best meets this requirement?

Accepted Answer

RA-GZRS. RA-GZRS (Read-Access Geo-Zone-Redundant Storage) is correct because it combines zone-redundant storage (ZRS) within the primary region to survive a single availability zone outage, and geo-redundant storage (GRS) to replicate data to a secondary region. The 'RA' prefix enables read access to the secondary region immediately after a primary region failure, allowing operations staff to read the most recently replicated copy even if writes are temporarily unavailable.

Answer

ZRS

Answer

GZRS

Answer

RA-GRS

Question 10

Based on the exhibit, what should you do so the report can open the file tomorrow morning?

Accepted Answer

Change the blob to the Hot access tier and allow it to rehydrate before the report runs.. The blob is currently in the Archive access tier, which requires manual rehydration (changing the tier to Hot or Cool) before it can be read. Rehydration can take up to 15 hours, so changing the blob to the Hot access tier now and allowing it to complete rehydration before the report runs tomorrow ensures the file is available for reading.

Answer

Change the blob to the Cool access tier only, because Cool is always immediately readable.

Answer

Create a snapshot of the archived blob and use the snapshot instead.

Answer

Enable versioning on the storage account so the file becomes readable again.
