A company has created an Azure Virtual machine as shown below. 

They want to ensure that a specific set of users have access to ‘Stop’ the virtual machine. Which of the following of the virtual machine would you use to fulfill this requirement?

Answer options:

A.Access Control (IAM)
B.Tags
C.Networking
D.Security

Answer – A 
If you go to the Access Control section, you can define a role assignment for a user that could conduct specific operations on the virtual machine. 

Since this is clear from the implementation, all other options are incorrect.
