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 Grid. Configure the machine identifier as the partition key and enable capture.

I think event hub. Azure Event Hub can be used to get the messages from the various devices. Azure Event Hub capture can then be used to persist the events to Azure Blob storage.

I agree. The solution says "enable capture". I have found capture only for Event Hub, not for Event Grid. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-capture-overview

No, the solution does not meet the goal. Azure Event Grid is primarily used for event-driven architectures and is designed to handle events and notifications. It is not suitable for directly ingesting and storing large amounts of data, such as the 2 MB of data per device per day from 2,000 stores.

Its Eventhub, grid is primarly for event routing, allowing other resources like functions to react to changes from a blobstorage etc. Event hub is the choice for streaming telemetry data from thousands of sources to a blobstorage.Here is a digestable documentation for understanding the difference between Hub, Grid and ServiceBus: https://arindam-das.medium.com/demystifying-azures-eventing-services-a-comparison-of-event-hub-event-grid-and-service-bus-d578693dcf16

"device data from 2,000 stores located throughout the world." It is a distributed data streaming. Answer is EventHub

Selected Answer: B

Given solution does not meet the goal because you are using Event Grid instead of Event Hubs. Event Grid does not have a capture feature and it does not store data in Blob storage. You need to use Event Hubs as your source and enable capture with Blob storage as your destination.

Selected Answer: B

B. No. Azure Event Grid is an event routing service that allows you to handle events from various Azure services and your own applications. It can be used to send events from an application to multiple subscribers, but it is not well suited for receiving data from thousands of devices and storing them in Azure Blob storage. Azure Event Grid is also not meant for long-term data storage and it is not a good fit for this scenario, where large amounts of data need to be stored and correlated based on a device identifier.

The reason for No is due to the max no. of partition. The question demands 5x2000 = 10000 parition, which is more than all tiers available. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-quotas#basic-vs-standard-vs-premium-vs-dedicated-tiers
