Question 2

4 Basic operations of NETWORK LAYER

Answer 2

• Addressing end devices
• Encapsulation
• Routing
• De-encapsulation

Question 3

T/F

The network layer performs five basic operations

• The IP addressing does not change from source to destination.

Answer 4

IP Encapsulation

Question 5

T/F

Network Address Translation (NAT) will change addressing during the IP Encapsulation

Answer 5

True

Question 6

Characteristics of IP

Answer 6

• Connectionless
• Best Effort
• Media Independent

Question 7

Answer 7

False: IP is connectionless
