Ace Your AZ-104 Azure Administrator Associate Exam

Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com.

The initial domain name cannot be changed or deleted, but you can add your corporate domain name to Azure AD as well. For example, your organization probably has other domain names used to do business and users who sign in using your corporate domain name. Adding custom domain names to Azure AD allows you to assign user names in the directory that are familiar to your users, such as ‘alice@contoso.com.’ instead of ' alice@domain name.onmicrosoft.com ' .

Scenario:

Network Infrastructure: Each office has a local data center that contains all the servers for that office. Each office has a dedicated connection to the Internet.

Humongous Insurance has a single-domain Active Directory forest named humongousinsurance.com

Planned Azure AD Infrastructure: The on-premises Active Directory domain will be synchronized to Azure AD.

Scenario: During the testing phase, auditors in the finance department must be able to review all Azure costs from the past week.

The question asks which storage account type should be created for storage5 and which existing storage account should be configured as the destination for replication — while supporting the planned changes.

Step 1: Planned Change Requirement

From the case study:

“Create a storage account named storage5 and configure storage replication for the Blob service.”

This indicates that storage5 will act as a secondary (destination) account to receive geo-replicated blobs (as part of RA-GRS or GRS replication configuration).

Therefore, the new storage5 must support Blob service replication features.

Step 2: Determining Correct Account Type

According to Microsoft Azure Administrator Documentation (Microsoft Learn: “Types of storage accounts”):

Account Type

Blob Support

File Share Support

Recommended Use

Storage (general purpose v1)

✅ Basic blob

Limited

Legacy use, lacks advanced features

StorageV2 (general purpose v2)

✅ Full blob, file, queue, table support

✅

Supports replication (GRS, RA-GRS, ZRS) and access tiers

BlobStorage

✅ Blob only

❌ No file shares

Used only for block and append blobs

BlockBlobStorage

✅ Blob only (premium tier)

❌ No file shares

High-performance workloads only

Therefore, the correct type for storage5 must be StorageV2, as it supports both:

Blob service replication (GRS, RA-GRS, ZRS, LRS)

All tiers (Hot, Cool, Archive)

This meets the planned change and ensures the account supports replication for Blob service.

Step 3: Determining the Correct Destination Storage Account

The question also requires identifying which existing storage account should act as the destination for replication configuration.

In Azure, Blob service replication (for example, geo-redundant replication or object replication) requires:

Both storage accounts to be StorageV2.

Both to be in the same region pair and have object replication enabled.

Looking at the table:

Storage Account

Kind

Location

File Share

Identity-based Access

storage1

Storage (general purpose v1)

West US

sharea

Azure AD DS

storage2

StorageV2 (general purpose v2)

East US

shareb, sharec

Disabled

storage3

BlobStorage

East US 2

N/A

N/A

storage4

FileStorage

Central US

shared

Azure AD DS

Only storage2 meets all of the following conditions:

✅ Type: StorageV2

✅ Region: East US (a valid replication pair for East US 2 or secondary region)

✅ Blob Service supported

Hence, storage2 is the correct destination storage account to configure for replication from storage5.

Step 4: Supporting Microsoft Azure Documentation Extracts

From Microsoft Learn – Azure Storage account overview:

“General-purpose v2 accounts support all Azure Storage features, including blob, file, queue, and table storage. They are recommended for most scenarios.”

“Object replication requires both source and destination accounts to be of the same type (StorageV2) and in regions that are geo-paired.”

“Blob and StorageV2 accounts support replication options such as LRS, ZRS, GRS, and RA-GRS.”

✅ Yes, Yes, No
