Explanation

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. LDAP is an application protocol for querying and modifying data using directory services running over TCP/IP. Answer: A is incorrect. Kerberos is a secure protocol that supports ticketing authentication. A ticket is granted in response to a client computer authentication request by the Kerberos authentication server, if the request contains valid user credentials and a valid Service Principal Name (SPN). The ticket is then used by the client computer to access network resources. To authentication, the client and server computers must have a trusted connection to the domain Key Distribution Center (KDC). The task of KDC is to distribute shared secret keys to enable Answer: C is incorrect. User Datagram Protocol (UDP) is often used for one-to-many communications, using broadcast or multicast IP datagrams. Microsoft networking uses UDP for logon, browsing, and name resolution. UDP is a connectionless and unreliable communication protocol. It does not guarantee delivery or verify sequencing for any datagram. UDP provides faster transportation of data between TCP/IP hosts than TCP. Answer: B is incorrect. Simple Network Management Protocol (SNMP) is a part of the TCP/IP protocol suite, which allows users to manage the network. SNMP is used to keep track of what is being used on the network and how the object is behaving.
