- A
Assign the 'Azure Event Hubs Data Sender' role and 'Storage Blob Data Reader' role.
Why wrong: Incorrect: Sender is for sending, not receiving; Reader is read-only.
- B
Assign the 'Azure Event Hubs Data Reader' role (which does not exist) and 'Storage Blob Data Contributor' role.
Why wrong: Incorrect: Event Hubs Data Reader is not a valid role; correct role is Data Receiver.
- C
Assign the 'Azure Event Hubs Data Receiver' role to the managed identity on the Event Hubs namespace. Assign the 'Storage Blob Data Contributor' role to the managed identity on the storage account.
Correct: correct roles for reading from Event Hubs and writing to Blob.
- D
Assign the 'Azure Event Hubs Data Owner' role and 'Storage Blob Data Owner' role.
Why wrong: Incorrect: Data Owner is too permissive.
Quick Answer
The correct answer is to assign the 'Azure Event Hubs Data Receiver' role to the managed identity on the Event Hubs namespace and the 'Storage Blob Data Contributor' role to the managed identity on the storage account. This works because managed identities provide Azure AD-authenticated access to resources without storing credentials; the Event Hubs trigger requires the Data Receiver role to pull messages, while the function’s output binding to Blob Storage needs the Data Contributor role to write blob data. On the AZ-204 exam, this scenario tests your understanding of role-based access control (RBAC) for serverless integrations, often appearing as a distractor where candidates mistakenly assign contributor roles to Event Hubs or storage account keys. A common trap is confusing 'Event Hubs Data Sender' with 'Receiver'—remember the function is consuming, not producing, events. For Blob Storage, avoid using the generic 'Storage Account Contributor' which grants management plane access, not data plane writes. Memory tip: think "Receiver for reading, Contributor for writing blobs."
AZ-204 Practice Question: Connect to and consume Azure services and third-party services
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Contoso is building a serverless application using Azure Functions. One function needs to read messages from an Azure Event Hub and store them in Azure Blob Storage. The function uses the Event Hubs trigger. The team wants to authenticate to both Event Hubs and Blob Storage using managed identities. The Function app has system-assigned managed identity enabled. Which role assignments are required on the Event Hubs namespace and the storage account?
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
Assign the 'Azure Event Hubs Data Receiver' role to the managed identity on the Event Hubs namespace. Assign the 'Storage Blob Data Contributor' role to the managed identity on the storage account.
For Event Hubs, the managed identity needs 'Azure Event Hubs Data Receiver' role. For Blob Storage, it needs 'Storage Blob Data Contributor' role. Option A is correct. Option B has wrong roles. Option C uses wrong roles. Option D has wrong roles.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
