Quick Answer
The answer is Azure Event Hubs, as it is the only service purpose-built for high-throughput ingress, capable of ingesting millions of events per second with low latency. This is achieved through its partitioned consumer model and support for AMQP and HTTPS protocols, allowing massive parallel processing of streaming data. On the AZ-204 exam, this question tests your ability to differentiate Azure messaging services under high-load scenarios—a common trap is confusing Event Hubs with Service Bus, which is designed for enterprise messaging with lower throughput and transactional guarantees. Another pitfall is choosing IoT Hub, which handles device connectivity and management, not raw event ingestion at this scale. Remember the memory tip: "Event Hubs for high-volume events, Service Bus for business messages." This distinction is critical when the scenario emphasizes raw data ingestion speed over message routing or device management.
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.
You are building a solution that needs to send millions of events per second to Azure for processing. Which Azure service should you use to ingest the events?
Azure Service Bus
Why wrong: Service Bus is for message queues and topics, not for high-throughput event ingestion.
Azure Event Hubs
Event Hubs is a big data streaming platform and event ingestion service.
Azure IoT Hub
Why wrong: IoT Hub is for bidirectional communication with IoT devices.
Azure Notification Hubs
Why wrong: Notification Hubs is for sending push notifications to mobile devices.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Event Hubs
Azure Event Hubs is designed for high-throughput data ingestion, capable of handling millions of events per second. Option A is wrong because Service Bus is for enterprise messaging with lower throughput. Option B is wrong because IoT Hub is for IoT device connectivity. Option D is wrong because Notification Hubs is for push notifications.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Service Bus
Why it's wrong here
Service Bus is for message queues and topics, not for high-throughput event ingestion.
Azure Event Hubs
Why this is correct
Event Hubs is a big data streaming platform and event ingestion service.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
