IETF IANA IEEE

Which two protocols function at the internet layer? (Choose two.) BOOTP IP POP ICMP PPP

IP ICMP

What process is used to place one message inside another message for transfer from the source to the destination? decoding encapsulation access control flow control

encapsulation

Which type of communication will send a message to a group of host destinations simultaneously? multicast anycast broadcast unicast

multicast

What is the general term that is used to describe a piece of data at any layer of a networking model? protocol data unit packet frame segment

protocol data unit

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

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

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

transport

What is done to an IP packet before it is transmitted over the physical medium? It is tagged with information guaranteeing reliable delivery. It is encapsulated in a Layer 2 frame. It is segmented into smaller individual pieces. It is encapsulated into a TCP segment.

It is encapsulated in a Layer 2 frame.

What are two benefits of using a layered network model? (Choose two.) It speeds up packet delivery. It prevents technology in one layer from affecting other layers. It ensures a device at one layer can function at the next higher layer. It prevents designers from creating their own model. It assists in protocol design.

It prevents technology in one layer from affecting other layers. It assists in protocol design.

What type of communication will send a message to all devices on a local area network? multicast unicast allcast broadcast

broadcast

Which message delivery option is used when all devices need to receive the same message simultaneously? multicast duplex broadcast unicast

broadcast

What process is used to receive transmitted data and convert it into a readable message? flow control encapsulation decoding access control

decoding

Which logical address is used for delivery of data to a remote network? destination IP address source IP address source MAC address destination MAC address destination port number

destination IP address

In computer communication, what is the purpose of message encoding? to convert information to the appropriate form for transmission to break large messages into smaller frames to negotiate correct timing for successful communication to interpret information

to convert information to the appropriate form for transmission
