Explanation

The Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL. SSL uses a program layer located between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of both the Microsoft and Netscape browsers and most Web server products. URLs that require an SSL connection start with https: instead of http:. Transport Layer Security (TLS) is a cryptographic protocol that provides security and data integrity for communications over networks such as the Internet. Answer option B is incorrect. Internet Packet Exchange/Sequenced Packet Exchange (IPX/SPX) is a protocol used by Novell NetWare clients to connect to NetWare server. IPX/SPX is a routable protocol. It is supported by Microsoft operating systems. IPX/SPX can be used for both large and small networks. The Internet does not use this protocol. Answer option A 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. Answer option C is incorrect. Hypertext Transfer Protocol (HTTP) is a client/server TCP/IP protocol used on the World Wide Web (WWW) to display Hypertext Markup Language (HTML) pages. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when a client application or browser sends a request to the server using HTTP commands, the server responds with a message containing the protocol version, success or failure code, server information, and body content, depending on the request. HTTP uses TCP port 80 as the default port.
