Which protocol is a cross-platform protocol that centralizes information about clients and objects on the network?

• A. Diameter
• B. LDAP
• C. 802.1x
• D. EAP

Answer: (B)

LDAP is a protocol for directory services that provides a centralized, cross-platform way to access and manage information about people, devices, and other objects in a network. It organizes data in a hierarchical directory where each entry has attributes (such as user name, email, group memberships) and can be queried, added, modified, or deleted. This central store acts as a single source of truth for identity and resource information, enabling consistent authentication and authorization across different systems and platforms.

Diameter, by contrast, is focused on authentication, authorization, and accounting in telecom and IP networks, not on storing directory information. 802.1X governs network access control and uses credentials and authentication methods, but it isn’t a directory service itself. EAP is an authentication framework used within various network access control methods, not a directory that centralizes object data.
