WGU C172 Network and Security Foundations QUESTIONS WITH COMPLETE SOLUTIONS

TCP/IP (Transmission Control Protocol/Internet Protocol) correct answer: A set of protocols made up of four layers (Application, Transport, Network, Network Interface Layer) used to connect network devices to each other Network Interface Layer (TCP/IP) correct answer: TCP/IP model layer that establishes how data should be physically sent through the network. Ethernet In conjunction with layers 1 PHYSICAL and 2 DATA LINK Network Layer (TCP/IP) correct answer: TCP/IP model layer that defines the logical transmission protocols for the whole network. - IP ( Internet Protocol) - ARP ( Address Resolution Protocol) - ICMP (Internet Contol Message Protocol) - IGMP in conjunction with layer 3 NETWORK of the OSI Model. Transport Layer (TCP/IP) correct answer: TCP/IP model layer that s responsible for the end-to-end transport of data. The protocols that live in this layer are. - TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) In conjunction with layer 4 TRANSPORT of the OSI Model Application Layer (TCP/IP) correct answer: TCP/IP model layer that is responsible for the communication protocols between nodes. The protocols in this layer include. - HTTP (Hyper Text Transfer Protocol) - SSH (Secure Shell) - FTTP - Telnet - NTP (Network Time Protocol) - DHCP - PING
