Exam AZ-204 topic 6 question 20 discussion

Actual exam question from Microsoft's AZ-204
Question #: 20
Topic #: 6
[All AZ-204 Questions]

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores located throughout the world. A single device can produce
2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data.
You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future.
You need to implement a solution to receive the device data.
Solution: Provision an Azure Event Hub. Configure the machine identifier as the partition key and enable capture.
Does the solution meet the goal?

  • A. Yes
  • B. No

Answer is YES :) Why do you want to have so many partitions? For me, it would be pretty strange to have so many concurrent groups. In the Event HUB output group you can have whether you want a Service bus, account storage, stream analytics (to aggregate data) and more ...

I have to agree. You don't need as many partitions as there are devices. Partition key is used in function to determine partition (like hashing function). So you could have 2000 devices and for example 10 partitions. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-features#publishing-an-event

But when you use Event Hubs cluster then you can purchase up to 20 Capacity Units and every Capacity Unit can have 2000 partitions.

Yes, the solution does meet the goal. Azure Event Hubs is a big data streaming platform and event ingestion service. It can receive and process millions of events per second. By configuring the machine identifier as the partition key, the data from each POS device will go to a specific partition. This allows for correlation based on the device identifier. The Capture feature of Azure Event Hubs enables automatic delivery of the streaming data in Event Hubs to an Azure Blob storage account. This would meet the requirement of storing the device data in Azure Blob storage.

Copilot and chatGPT say YES whith the same explanation : Scalability: Azure Event Hub is highly scalable and can handle the ingestion of large amounts of data from thousands of devices. It can easily accommodate the data from 2,000 stores, each having one to five devices. Partitioning: Using the machine identifier as the partition key ensures that data from the same device is sent to the same partition. This makes it easier to correlate and process data per device. Capture: Enabling capture in Azure Event Hub allows the data to be automatically stored in Azure Blob Storage in a highly efficient manner. This setup simplifies the pipeline from ingestion to storage. Future Growth: Azure Event Hub can scale out to accommodate additional stores and devices as they come online, making it a future-proof solution.

Selected Answer: B
The solution mentions "Configure the machine identifier as the partition key" that means up to 10,000 partitions. That would mean a dedicated cluster with up t0 5 CUs. The solutions does not state a dedicated cluster the max partitions are that 1024.

Partition KEYS are only used to ensure that all events with the same key end up in the same partition. The ACTUAL partition can have events from many, many different machines. It is perfectly fine to have this many partition KEYS, Event Hub will handle the creation of actual partitions and delegate events to them under the hood.

Copilot: The proposed solution uses Azure Event Hubs with capture enabled to store POS device data in Azure Blob Storage. Technically, this is feasible. However, it might not be the most efficient or cost-effective method. Despite this, if we disregard best practices, the solution could work.

The recommendation from Microsoft: https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-features#mapping-of-events-to-partitions "A per-device or user unique identity makes a good partition key, but other attributes such as geography can also be used to group related events into a single partition." The correct answer is YES.

Selected Answer: A
The solution scales well to accommodate the current load and future expansions as more stores open. Using the device identifier as the partition key ensures that data correlation is straightforward and efficient. By enabling the Capture feature, the data is automatically saved to Azure Blob storage, meeting the storage requirement. Event Hubs has a feature called Capture, which automatically captures the streaming data and saves it to a storage account (Azure Blob storage or Azure Data Lake Storage), without requiring any additional coding or services to process the data. This directly aligns with the requirement to store the device data in Azure Blob storage.

The theoretical partition limit for a Eventhub is 1024, and it can hold up to 1000 event hubs per namespace. It's totally fine to scale out within a namespace/scope to add more partitions to handle incoming data. plz see the different tiers: https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-quotas and read about namespaces: https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-features

Azure Event Hub is primarily designed for handling high-throughput, real-time event streaming, such as telemetry data and event-driven architectures. It's not the best choice for storing large volumes of static data like 2 MB of POS device data per device per day
