Networking Encapsulation Quiz

What is packet encapsulation in networking?

• The process of stripping headers and trailers from a packet

• The process of adding an IP address to a packet

• The process of adding headers and trailers to data

• The process of checking for errors in network transmission

Which layer of the OSI model is primarily responsible for encapsulation?

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

What is the primary purpose of encapsulation in networking?

• To increase the speed of data transmission

• To ensure data can be safely and effectively transmitted over the network

• To reduce the size of the data being transmitted

• To encrypt data

Which of the following is NOT an encapsulation protocol?

• Ethernet

• PPP (Point-to-Point Protocol)

• HTTP (Hypertext Transfer Protocol)

• Frame Relay

During encapsulation, what happens immediately after the Transport layer header is added to the data segment?

• The data is transmitted over the network.

• The Network layer adds its header.

• The Data Link layer adds its header and trailer.

• The data is converted into bits.

What is the correct order of layers involved in encapsulation, from the highest to the lowest?

• Application, Transport, Network, Data Link, Physical

• Physical, Data Link, Network, Transport, Application

• Application, Presentation, Session, Transport, Network

• Data Link, Network, Transport, Application, Physical

In the context of networking, what is decapsulation?

• Adding headers to the data packet

• Encrypting data for secure transmission

• Removing headers and trailers from a packet

• Increasing the size of the data packet

Which layer of the OSI model is primarily responsible for decapsulation?

• Application Layer

• Transport Layer

• Data Link Layer

• Physical Layer

What is the first step in the decapsulation process when a packet is received?

• The Transport layer header is removed.

• The Data Link layer trailer is removed.

• The Network layer header is analyzed.

• The Physical layer converts signals into data.

Why is decapsulation necessary in networking?

• To increase the transmission speed

• To convert the packet back into the original data format

• To add additional security layers

• To compress the data for storage
