Full question →mediummultiple choiceObjective-mapped
You are developing a worker role that processes events from an Azure Event Hub. The worker runs on multiple virtual machines to ensure high availability. Each partition of the Event Hub should be processed by only one instance at a time, and events from the same partition must be processed in order. You need to manage partition leasing and checkpointing efficiently. Which Azure SDK class should you use?
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
EventHubClient
EventHubClient is used to send events or create receivers for specific partitions, but it does not include partition leasing or checkpointing logic.
B
Distractor review
PartitionReceiver
PartitionReceiver allows you to receive events from a specific partition, but you must manually manage offset/checkpoint and partition distribution among multiple instances.
C
Distractor review
EventHubConsumerClient
The newer EventHubConsumerClient provides simple consumption but lacks built-in partitioning and checkpointing; you would need to implement your own lease strategy.
D
Best answer
EventProcessorHost
EventProcessorHost abstracts partition leasing, checkpointing, and ensures that each partition is processed by a single instance. It processes events in order within partitions and is ideal for high-availability scenarios.
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-204 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: EventProcessorHost — The EventProcessorHost class (often from the Microsoft.Azure.EventHubs.Processor package) simplifies building reliable event processors. It handles partition leasing among multiple instances, checkpointing to Azure Storage, and ensures ordered processing within each partition. EventHubClient (A) is used for sending events, not processing. PartitionReceiver (B) is a low-level class that does not provide leasing or checkpointing. EventHubConsumerClient (C) is part of the new SDK but lacks built-in lease management; you would need to implement it yourself.
