Certified Ethical Hacker (CEH v10) — Question 44

An LDAP directory can be used to store information similar to a SQL database. LDAP uses a ____ database structure instead of SQL's ______ structure.
Because of this, LDAP has difficulty representing many-to-one relationships.

Answer options

• A. Strict, Abstract
• B. Simple, Complex
• C. Relational, Hierarchical
• D. Hierarchical, Relational

Correct answer: D

Explanation

The correct answer is D because LDAP uses a hierarchical database structure, which organizes data in a tree-like format, while SQL uses a relational structure based on tables. This hierarchical model makes it inherently difficult for LDAP to effectively represent many-to-one relationships, which are easily managed in a relational database.
