Networking Protocols Telnet (23) - CORRECT ANSWER-Allows a user on a remote client machine, called the Telnet client, to access the resources of another machine, the Telnet server. File Transfer Protocol (FTP) (20,21) - CORRECT ANSWER-Allows you to transfer files across an IP network, and it can accomplish this between any two machines that are using it. Secure File Transfer Protocol (SFTP) (22) - CORRECT ANSWER-Used when you need to transfer files over an encrypted connection. It uses SSH which encrypts the connection. It's basically secure FTP.

Allows you to connect to another computer and run programs. Transport Layer Security/Secure Socket Layer (TLS/SSL) (995/465) - CORRECT ANSWER-These are cryptographic protocols that come in really handy for enabling secure online data-transfer activities like browsing the Web, instant messaging, Internet faxing, and so on. Session Initiation Protocol (VoIP) (SIP) (5060/5061) - CORRECT ANSWER-Hugely popular signaling protocol used to construct and deconstruct multimedia communication sessions for many things. Real-time Transport Protocol (RTP) (VoIP) (5004/5005) - CORRECT ANSWER-A packet-formatting standard for delivering audio and video over the Internet. Designed as multicast but is now used for unicast as well. Media Gateway Control Protocol (MGCP) (Multimedia) (2427/2727) - CORRECT ANSWER-Standard protocol for handling the signaling and session management needed during a multimedia conference. H.323 (video) (1720) - CORRECT ANSWER-Provides a standard for video on an IP network that defines how real-time audio, video, and data information is transmitted. Simple Network Management Protocol (SNMP) (161) - CORRECT ANSWER-Collects and manipulates valuable network information. Used to help monitor networks and inform administrators when there is a problem. Secure Shell (SSH) (22) - CORRECT ANSWER-Sets up a secure Telnet session over a standard TCP/IP connection is is employed for doing links like logging into other systems, running programs on remote systems, and moving giles from one system to another. Hypertext Transfer Protocol (HTTP) (80) - CORRECT ANSWER-Manages communications between web browsers and web servers, and opens the right resources when you click on a link. Network Time Protocol (NTP) (123) - CORRECT ANSWER-Syncs clocks with each other so everyone has the same time. Lightweight Directory Access Protocol (LDAP) (389) - CORRECT ANSWER-Software uses this protocol to keep track of all your network resources, such as devices and users. Internet Group Management Protocol (IGMP) - CORRECT ANSWER-TCP/IP protocol used for managing IP multicast sessions. Sends out a multicast packet to find out what machines are on what group. Serial Line IP (SLIP) - CORRECT ANSWER-A protocol created with the IP protocol stack and designed to work over serial ports and modem connections. NetBIOS (137-139) - CORRECT ANSWER-Works only in the upper layers of the OSI model and allows for an interface on separate computer to communicate over a network. Server Message BLock (SMB) (445) - CORRECT ANSWER-Used for sharing access to files and printers and other communications between hosts on a Microsoft Windows Network. Domain Name Service (DNS) (53) - CORRECT ANSWER-Resolves hostnames - specifically, Internet names. Dynamic Host Configuration Protocol (DHCP) (67) - CORRECT ANSWER-Assigns IP addresses to hosts with information
