7. 7 Summary Questions 1. Directory Applications has subdirectories Databases and WordProcessings. The Network administrator assigns user Lee to the group Outer. The administrator assigns Outer the access rights R, S, and T in Directory Applications. (Don’t worry about the meaning of R, S, and T. They are simply types of rights.) The administrator assigns Outer the access rights S, U, and V in subdirectory Databases. a) What access rights does user Lee have in directory Applications? Explain. b) What access rights does user Lee have in directory Databases? Explain. c) What access rights does user Lee have in directory WordProcessings? Explain.
