LDAP can be used ________.

• 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 a protocol for accessing and managing information in a directory service. It supports both retrieving data and updating data stored in the directory. You can perform searches to read attributes of entries, and you can modify the directory by adding new entries or changing existing attributes (such as updating a user’s phone number or email). Because LDAP covers both read and write operations, it can be used to update information in the directory server and to retrieve data from the directory server. This dual capability is what makes LDAP a versatile backend for authentication directories, address books, and other centralized datasets.
