Answer:
a. Enable user authentication on the printer share.
Step-by-step explanation:
a. Enable user authentication on the printer share.
-The manager only wants specific people to access print so can only give access to these people by enabling user authentication.
b. Disable print spooling on the marketing.
-In that condition no one can print so this will be not useful.
c. Set security permissions for the marketing PC's signed-in user.
- Security permissions are about the PC itself not about the access to PC. Well again anyone can access to a printer.
d. Disable the local share on the marketing PC
- If the local share is disabled then only one computer can print. No one can print from marketing teams.
