You need to meet the technical requirement for VM4.
What should you create and configure?
A . an Azure Notification Hub
B . an Azure Event Hub
C . an Azure Logic App
D . an Azure services Bus
Answer: B
Explanation:
Scenario: Create a workflow to send an email message when the settings of VM4 are modified.
You can start an automated logic app workflow when specific events happen in Azure resources or third-party resources. These resources can publish those events to an Azure event grid. In turn, the event grid pushes those events to subscribers that have queues, webhooks, or event hubs as endpoints. As a subscriber, your logic app can wait for those events from the event grid before running automated workflows to perform tasks – without you writing any code.
