What is a topic in Azure Event Grid?

A topic is a user-defined endpoint where event sources send events. Subscribers listen to topics to receive events.

What role does Azure Event Grid play in cloud applications?

A Routes events from sources to handlers

B Stores large amounts of data

C Manages virtual machines

D Provides database services

Azure Event Grid routes events from sources to handlers, enabling event-driven architectures.

Which of the following can be an event handler in Event Grid?

A Azure Functions

B Azure Virtual Machines

C Azure Blob Storage

D Azure SQL Database

Azure Functions can process events as event handlers in Event Grid.

What is the purpose of a topic in Event Grid?

A To create virtual networks

B To receive events from sources

C To run code on events

D To store event data permanently

A topic is where event sources send events for routing.

How does Event Grid help applications scale?

A By creating more virtual machines

B By increasing CPU power

C By storing data in databases

D By decoupling event producers and consumers

Decoupling producers and consumers allows independent scaling and flexibility.

Which service is NOT typically an event source for Event Grid?

A Azure Blob Storage

B Custom applications

C Azure Virtual Machines

D Azure Logic Apps

Azure Virtual Machines are not event sources; they can run event handlers but do not emit events directly.

Explain how Azure Event Grid routes events from sources to handlers.

Think about how messages travel from where they start to where they are used.

Describe the benefits of using Event Grid in cloud applications.

Consider how Event Grid helps apps respond quickly and grow easily.
