Packet

Question 5

Authentication and authorization take place at the:

Application layer of the OSI model

Network layer of the OSI model

Session layer of the OSI model

Presentation layer of the OSI model

Answer 5

Session layer of the OSI model

Question 6

In the context of the OSI model, the term “Data encapsulation” is used to describe a process where each layer of the OSI model adds its own control information to the original data that is being passed across the layers from the physical layer up to the application layer.

True or False?

Answer 6

False

Encapsulation is the process of adding additional information when data is traveling in an OSI or TCP/IP model. The information has been added on the sender’s side, from the Application layer to the Physical layer.

Question 7

In the OSI model, the layer 4 TCP PDU is known as:

Bit

Frame

Packet

Segment

Datagram

Answer 7

Segment

In the OSI model, the layer 4 TCP PDU is known as a segment. The layer 4 PDU is also known as a datagram when using the User Datagram Protocol (UDP).

Question 8

In the OSI model, the layer 4 UDP PDU (Protocol Data Unit) is called:

Bit

Frame

Packet

Segment

Datagram

Answer 8

Datagram

In the OSI model, the layer 4 TCP PDU is known as a segment. The layer 4 PDU is also known as a datagram when using the User Datagram Protocol (UDP).
