TFTP
B.
LDAP

SSL
D.
TLS
Explanation:
Lightweight Directory Access Protocol (LDAP) is a protocol used to query and modify information stored within directory services. The Lightweight Directory Access Protocol (LDAP) is a standard protocol, which provides access to the directory. It also provides a common language for LDAP clients and servers to communicate with each other. The LDAP is commonly used as standard in the industry. By using a directory service such as LDAP, information existing in multiple systems and formats can be brought at one place.
Answer options C and D are incorrect. The Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols are used to provide transport level security for Web services applications.Answer option A is incorrect. Trivial File Transfer Protocol (TFTP) is a file transfer protocol, with the functionality of a very basic form of File Transfer Protocol (FTP). TFTP can be implemented in a very small amount of memory. It is useful for booting computers such as routers which did not have any data storage devices. It is used to transfer small amounts of databetween hosts on a network, such as IP phone firmware or operating system images when a remote X Window System terminal or any other thin client boots from a network host or server.
The initial stages of some network based installation systems (such as Solaris Jumpstart, Red Hat Kickstart and Windows NTs Remote Installation Services) use TFTP to load a basic kernel that performs the actual installation. TFTP uses UDP port 69 for communication.
