Correct Answer: B
When you decide to use direct assignment, both the personal desktop host pool and a specific session host must be assigned to the users before they can connect to their personal desktop. If the users are assigned only to a host pool without assigning a session host, they will not be able to access resources. In Direct assignment, the users are assigned a session host and will only access that session host for future logins.
