LDAP can be used to update and retrieve information from a directory server.

• A. To update information in the directory server
• B. To retrieve data from the directory server
• C. Both A and B
• D. Neither A nor B

Answer: (C)

LDAP is designed to access and manage information stored in a directory. It supports both retrieving and updating directory entries. Retrieval happens with a search operation, where a client queries the directory and gets back matching entries and their attributes. Updates are performed with modify (and add for new entries) operations to change or create data in the directory. Because both types of operations are defined and commonly used, LDAP can update and retrieve information from a directory server.
