Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company stores sensitive files in Azure Files shares. They require that data is encrypted at rest using a customer-managed key (CMK) stored in Azure Key Vault, and that all client connections use SMB 3.0 encryption for end-to-end encryption in transit. They create a premium Azure Files share in a storage account and configure encryption at rest with a CMK. However, clients are unable to connect without SMB encryption. What additional configuration is necessary to enforce SMB encryption for all connections?
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
Distractor review
No additional configuration is needed; Azure Files uses SMB encryption by default and cannot be disabled.
Azure Files supports SMB 3.0 encryption, but it is not enforced by default. The 'Secure transfer required' setting must be enabled to require encryption.
B
Best answer
Enable 'Secure transfer required' in the storage account's configuration to enforce SMB 3.0 encryption.
When 'Secure transfer required' is enabled, the storage account accepts only encrypted connections (HTTPS and SMB 3.0 with encryption). For Azure Files, this means clients must use SMB 3.0 encryption to connect.
C
Distractor review
Configure a network security group (NSG) rule to block SMB traffic on port 445 that does not use encryption.
NSGs do not inspect encryption; they filter traffic based on IP and port. They cannot enforce encryption requirements on the SMB protocol itself. That is a storage-level setting.
D
Distractor review
Set the Azure Files share to use the 'Premium' performance tier; encryption is only available on premium shares.
While CMK for Azure Files is only available on premium shares, SMB encryption enforcement is available on both standard and premium shares via the 'Secure transfer required' setting.
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.

Questions learners often ask
What does this AZ-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Enable 'Secure transfer required' in the storage account's configuration to enforce SMB 3.0 encryption. — Azure Files supports SMB encryption which can be enforced at the storage account level. When you require secure transfer (SMB 3.0 encryption), the storage account rejects any connection that does not use SMB 3.0 encryption. This is configured in the storage account's 'Configuration' settings under 'Secure transfer required'. For Azure Files, this setting enforces SMB encryption for file share access.
