Which of the following is NOT a characteristic of a client in the
client/server model?

A.
May be diskless

B.
Systems backup and database protection

C.
Extensive user interface

D.
Data entry screens

Explanation:
In the client/server model, the server is the data storage resource
and is responsible for data backups and protection/maintenance of
the database.
Answer “May be diskless” refers to a diskless workstation or PC at the
client side. By not providing local data storage capabilities at the
client side, security is increased since the data is less vulnerable at a
protected server location. Also, because the client is the users path
into the network, the client must have extensive, user friendly interfaces
such as described in answers Extensive user interface and Data entry screens.
