Rory is studying the fields inside an Ethernet frame for an upcoming test and notices that the destination Media Access Control (MAC) address is listed first before the source MAC address. Which of the following protocol characteristics is Rory investigating? encapsulation timing message pattern message timing encoding

Encapsulation

Which three acronyms/initialisms represent standards organizations? (Choose three.) IANA TCP/IP IEEE IETF OSI MAC

IANA, IEEE, IETF

Which organization publishes and manages the Request for Comments (RFC) documents? IEEE ISO IETF TIA/EIA

IETF

Which protocol is used by routers to forward messages? HTTP TCP IP Ethernet

IP

As Rory continues to study Ethernet, he discovers that a frame can typically be 64 to 1518 bytes of information that is converted into a series of bits before being sent out on the network. Which two protocol characteristics did Rory learn about for Ethernet? message size timing encoding encapsulation message pattern

Message size, encoding

Bianka, a Polish traveler in Hanoi, Vietnam, stops and asks Nguyệt for directions to the Ngoc Son Temple. They verbally communicate and determine that they both speak English. After receiving directions in English to the temple, Bianka repeats them to Nguyệt. Nguyệt says, "Yes, that is correct." Select the order of the communications protocols used in this scenario? language, method, confirmation method, confirmation, language confirmation, method, language method, language, confirmation

Method, language, confirmation

IP addressing occurs at what layer of the OSI Model? application presentation session transport network data link physical

Network

What networking term describes a particular set of rules at one layer that govern communication at that layer? duplex encapsulation error checking protocol

Protocol

The rules that govern network communications including the message format, message size, timing, and encapsulation, are known as network: encoding signaling messaging protocols

Protocols

What is the purpose of protocols in data communications? specifying the bandwidth of the channel or medium for each type of communication specifying the device operating systems that will support the communication providing the rules required for a specific type of communication to occur dictating the content of the message sent during communication

Providing the rules required for a specific type of communication to occur

The IETF (Internet Engineering Task Force) records and publishes internet standards in documents known as: Request for Comments (RFC) Internet Protocol Standards (IPS) Internet Specification Standards (ISS) IETF Standards Documents (ISD)

Request for Comments (RFC)

Which three layers of the OSI model make up the application layer of the TCP/IP model? (Choose three.) data link network transport session presentation application

Session, Presentation, Application

Which term refers to the set of rules that define how a network operates? standard protocol model domain

Standard

This protocol is responsible for guaranteeing the reliable delivery of information. TCP IP HTTP Ethernet

TCP

Which statement is correct about network protocols? Network protocols define the type of hardware that is used and how it is mounted in racks. They define how messages are exchanged between the source and the destination. They all function in the network access layer of TCP/IP. They are only required for exchange of messages between devices on remote networks.

They define how messages are exchanged between the source and the destination.

What is the purpose of the OSI physical layer? controlling access to media transmitting bits across the local media performing error detection on received frames exchanging frames between nodes over physical network media

Transmitting bits across the local media

Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices? application presentation session transport network

Transport
