Your company has a set of Azure Pipelines defined. You need to create an integration between Azure Pipelines and Slack. You have to send build notifications to a Slack channel. Which of the following is a step in the implementation plan for achieving this?

Answer options:

A.Configure a new service connection.
B.Configure a new service hook subscription.
C.Create a new project-level notification.
D.Create a new organization-level notification.

Answer – B 
You can achieve this with the help of a service hook subscription. In the service hook, you can subscribe to the Slack channel for a specific event. 
Option A is incorrect since you have to create a service hook subscription and not a connection. 
Options C and D are incorrect because having notifications will not help. You have to create a service hook subscription to Slack. 
Since this is clearly given in the Microsoft documentation, all other options are incorrect.
