- A
Enable system-assigned managed identity on the Stream Analytics job and configure the output to use it.
This is the correct method to use managed identity for authentication.
- B
Generate a shared access signature (SAS) token for the Synapse Analytics workspace.
Why wrong: SAS tokens are not used for Synapse Analytics authentication from Stream Analytics.
- C
Create a user-assigned managed identity and assign it to the Stream Analytics job.
Why wrong: While possible, system-assigned managed identity is simpler and sufficient.
- D
Configure the output to use SQL Server authentication with a username and password.
Why wrong: This is not managed identity authentication.

DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You have an Azure Stream Analytics job that writes output to Azure Synapse Analytics. You need to ensure that the job can authenticate to Synapse Analytics using a managed identity. What should you do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable system-assigned managed identity on the Stream Analytics job and configure the output to use it.
To authenticate to Azure Synapse Analytics using a managed identity, you should enable the system-assigned managed identity on the Stream Analytics job (it is enabled by default) and then configure the output to use managed identity authentication. Option A is correct. Option B is incorrect because a SAS token is not a managed identity. Option C is incorrect because while a user-assigned managed identity could be used, the system-assigned managed identity is sufficient and is the simpler option. Option D is incorrect because SQL Server authentication does not use managed identity and is less secure than managed identity authentication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
