Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A Windows VM and a Linux VM in the same on-premises Active Directory Domain Services domain must mount the same Azure Files share over SMB. Security policy forbids storage account keys and long-lived SAS tokens. What should the administrator configure?
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
Use Azure Files with Active Directory Domain Services authentication and grant permissions to the required AD group.
This provides password-based domain authentication for SMB access without using storage keys or SAS. Both Windows and Linux clients can mount the share when they are domain joined and the share permissions are assigned correctly.
B
Distractor review
Use a private endpoint and rely on network isolation instead of authentication.
Network isolation protects the path, but it does not authenticate users or satisfy the requirement to mount the share securely without keys or SAS.
C
Distractor review
Use the storage account access key because SMB requires shared-key authentication.
Shared keys are explicitly disallowed, and Azure Files supports identity-based authentication for this scenario.
D
Distractor review
Use Azure Files NFS authentication because Linux and Windows workloads can both mount it.
NFS is not the right answer for a mixed Windows and Linux SMB requirement, and Windows SMB interoperability is the key design point here.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Use Azure Files with Active Directory Domain Services authentication and grant permissions to the required AD group. — Azure Files with Active Directory Domain Services authentication is the right fit because the share must be mounted by both Windows and Linux servers that already belong to the same domain, and the security policy forbids shared keys and SAS. AD DS authentication provides identity-based SMB access, while share permissions control who can mount and use the file share. This preserves security and cross-platform compatibility. Why others are wrong: Private endpoints improve network security but do not provide user authentication to the share. Shared keys are specifically banned by the requirement. NFS is not the best choice for the scenario because the question requires SMB access from both Windows and Linux in a domain-authenticated environment, which Azure Files supports through AD DS authentication.
