Full question →mediummultiple choiceObjective-mapped
A Windows file server VM in Azure must mount an Azure file share by using existing Active Directory Domain Services credentials instead of a storage account key. The organization already has domain-joined Windows servers in the environment. What should the administrator configure on the storage account?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Enable Azure Files identity-based authentication with Active Directory Domain Services.
Azure Files can use AD DS-based Kerberos authentication for SMB access. This allows the VM to authenticate with existing domain credentials instead of using a storage account key.
B
Distractor review
Enable blob soft delete and mount the share with a blob container SAS token.
Soft delete protects deleted items, but it does not provide SMB authentication for Azure file shares. A blob SAS token is also not the right credential type for a file share mount.
C
Distractor review
Enable a service endpoint for Microsoft.Storage on the subnet.
A service endpoint can improve network access to storage, but it does not replace the authentication method. The question is about using AD DS credentials for the share.
D
Distractor review
Create a shared access signature for the file share and map it as a local drive.
A SAS token is not the same as SMB-based domain authentication. The requirement explicitly asks for existing AD DS credentials rather than a storage token.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Enable Azure Files identity-based authentication with Active Directory Domain Services. — For a Windows VM that should mount Azure Files by using existing domain credentials, Azure Files identity-based authentication with Active Directory Domain Services is the correct configuration. It lets the VM use Kerberos over SMB and aligns with organizations that already manage identities in AD DS. This avoids storage keys and gives centralized control over file share access. Why others are wrong: Soft delete and SAS tokens do not address domain-based SMB authentication. A service endpoint is a network feature, not an authentication method. Mapping a SAS token as a drive does not satisfy the requirement to use AD DS credentials already in place for the Windows file server.
