What should you do first?

You have an Azure subscription that contains an Azure Data Factory version 2 (V2) data factory named df1. Df1 contains a linked service.

You have an Azure Key vault named vault1 that contains an encryption key named key1.

You need to encrypt df1 by using key1.

What should you do first?
A . Disable purge protection on vault1.
B . Create a self-hosted integration runtime.
C . Disable soft delete on vault1.
D . Remove the linked service from df1.

Answer: D

Explanation:

Linked services are much like connection strings, which define the connection information needed for Data Factory to connect to external resources.
