Which of the following is not an attribute of LDAP directories?

A.
Uses distinguished names

B.
Uses attributes

C.
Uses values

D.
Uses tuples

Explanation:
The LDAP specification works with directories that organize their
database in a hierarchical tree structure. The tree has leaves (entries) with unique
distinguished names. These names are hierarchical and describe the objects place
within the tree. The entries can define network resources, computers, people,
wireless devices, and more. Each entry has an attribute and a value. A tuple is used
in a relational database, not a hierarchical database.
