Answer:
A. Access control list
Explanation:
The access control list contains a group of permissions that are attached to an object. These permissions grant system processes or users access to specific objects.
For instance, consider an object that has an ACL that contain (Mike: read, write; Kat: read; Tom: read, write, execute), Mike will be given permission to read and write, Tom will be granted permission to read, write and execute the object while Kat will only be allowed to read it.
In our scenario, for Derek to determine how members are authenticated on the network, the computer or server will use the Access control list.
