Selected Answer: A
In Azure Event Hubs, a publisher is essentially an identity or role that can send events to an event hub. Publisher policies allow you to define rules or policies that control how and what data can be published to an event hub. Using publisher policies, you can assign a unique identifier to each retailer (publisher) when they send data to the event hub. This approach enables fine-grained control over event data ingress, ensuring that retailers can only submit data for themselves.

ChatGPT: Sorry, but the correct answer is B. Creating a partition for each retailer ensures that each retailer only sees the events that pertain to them, as each partition in Event Hubs is an independent stream of events. This also allows for easy addition and removal of retailers, as you can simply add or remove partitions accordingly. Using publisher policies for retailers or defining a namespace for each retailer are not the correct solutions for this scenario.

B is incorrect. The number of partitions is specified at the time an Event Hubs is created and can't be changed. https://learn.microsoft.com/en-us/training/modules/azure-event-hubs/2-event-hubs-overview

ChatGPT gives me A as correct answer. "Using publisher policies allows you to control and manage access to the Azure Event Hub at a more granular level. You can create separate publisher policies for each retailer, and each policy can have its own set of permissions, including the ability to send events to the event hub. This approach ensures that each retailer can only record sales for themselves, and it allows for easy management of retailer access, including adding or removing retailers as needed."
