WGU C172 Network and Security Foundations Exa with Guaranteed Accurate Answers

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 In conjunction with Layers 5 SESSION, 6 PRESENTATION, AND 7 APPLICATION of the OSI model. Physical Layer (OSI model) - correct answer Layer 1 of the OSI Model responsible for the physical connections of the devices in the network. This layer is implemented through the use of devices such as hubs, repeaters, modem devices, and physical cabling. Data Link Layer (OSI Model) - correct answer Layer 2 of the OSI Model responsible for the error-free delivery of data to the receiving device or node. This layer is implemented through the use of devices such as switches and bridge devices, as well as anything with a network interface, like wireless or wired network cards. Network Layer (OSI Model) - correct answer Layer 3 of the OSI Model responsible for the transmission of data between hosts in different networks as well as routing of data packets. This layer is implemented through the use of devices such as routers and some switches. Transport Layer (OSI Model) - correct answer Layer 4 of the OSI Model provides services to the application layer and receives services from the network layer and is responsible for the reliable delivery of data. It segments and reassembles data in the correct order for it to be sent to the receiving device. It may also handle the reliable delivery of data and any retries of data that are lost or corrupted (for example, TCP does this). This layer is often called the heart of OSI.
