Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company wants to migrate its on-premises file server to Azure with minimal application changes. The application accesses files over the SMB protocol and requires identity-based access using the existing on-premises Active Directory Domain Services (AD DS). They need the solution to be fully managed with low latency. Which Azure storage solution should they choose?
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
Azure Files
Azure Files provides fully managed SMB file shares with on-premises AD DS authentication, ideal for lift-and-shift migration.
B
Distractor review
Azure NetApp Files
NetApp Files supports both SMB and NFS but is a more complex, high-performance service often used for specialized workloads; Azure Files is simpler for common file server migration.
C
Distractor review
Azure Blob Storage with NFS 3.0
Blob Storage supports NFS but does not support SMB, so the application would require changes to use NFS instead of SMB.
D
Distractor review
Azure Disk Storage
Disk Storage provides block-level storage for VM disks, not a file share accessible via SMB.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Files — Azure Files supports Server Message Block (SMB) protocol and can be integrated with on-premises AD DS for identity-based access. It is fully managed and offers low latency when accessed from Azure VMs or through ExpressRoute. Azure NetApp Files also supports SMB but is more complex and expensive. Blob Storage with NFS doesn't support SMB. Disk Storage is block-level and not designed for file sharing.
