Question 51 - 312-38 discussion

Lightweight Presentation Protocol (LPP) is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IPbased networks for some constrained environments. This protocol was initially derived from a requirement to run the ISO Common Management Information Protocol (CMIP) in TCP/IP-based networks.

This protocol is designed for a particular class of OSI applications, namely those entities whose application context includes only an Association Control Service Element (ACSE) and a Remote Operations Service Element (ROSE). Answer option D is incorrect. The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a clientserver architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and often error-prone undertaking. DHCP is popular with ISP's because it allows a host to obtain a temporary IP address.

Answer option A is incorrect. Answer option C is incorrect. Internet Relay Chat (IRC) is a chat service, which is a client-server protocol that supports real-time text chat between two or more users over a TCPIP network.
