I am using "Beachfront" to study for "Fundamentals II", and one of the questions is:

Connection Manager features cannot be used with which of the following naming method?

a - host naming

b - local naming

c - oracle names

d - names server

-- I thought the answer is "B" local naming, but for beachfront the answer is "A" host naming. The weird thing is the explanation states that Connection Manager works with the three-tier environment, isn't host naming used for three-tier environment and local naming for two-tier? I just want to verify that the software is all wrong.
