Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.
Lightweight Directory Access Protocol (LDAP) is the correct protocol used to locate resources on a network. UDP, mentioned in the question, is not specifically used for querying or locating resources but rather for providing fast, connectionless transmission of data packets. LDAP, on the other hand, is designed explicitly for querying and modifying directory services, thereby making it the appropriate protocol for this context.
