A

encapsulation

16
Q

True or false? The right-most part of an IP address is used to identify the network that a device belongs to.

A

False

16
Q

True or false? Frames exchanged between devices in different IP networks must be forwarded to a default gateway.

A

True

17
Q

What is the order of the two addresses in the data link frame?

A

destination MAC, source MAC

17
Q

What is used to determine the network portion of an IPv4 address?

A

subnet mask

17
Q

Which of the following statements are true regarding network layer and data link layer addresses? (Choose three.)

A
  • Network layer addresses are logical and data link addresses are expressed as 12 hexadecimal digits.
  • Data link layer addresses are physical and network layer addresses are logical.
  • Network layer addresses are either 32 or 128 bits in length.
18
Q

True or False? Data Link addresses are physical so they never change in the data link frame from source to destination.

A

HTTP, TCP, IP, Ethernet

21
Q

What are two benefits of using a layered network model? (Choose two.)

A
  • It assists in protocol design.
  • It prevents technology in one layer from affecting other layers.
22
Q

What is the purpose of protocols in data communications?

A

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