World of Computer Networking Your CCNA start - Static Network Address Translation (NAT)

The video tutorial explains how routers modify IP packets, focusing on Network Address Translation (NAT). It covers different types of NAT, including static and dynamic NAT, and provides detailed examples of static NAT translations. The tutorial highlights the importance of using appropriate IP addresses for successful packet routing and introduces dynamic NAT, where IP addresses are assigned dynamically.

What is the primary function of routers in the context of IP packet modification?

• To encrypt data in IP packets

• To alter the source ports in outgoing packets

• To modify source IP addresses in outgoing packets from private to public IP addresses

• To change the destination IP addresses in incoming packets

Which of the following is NOT a type of NAT mentioned in the video?

• Dynamic PAT

• Static PAT

• Dynamic NAT

• Static NAT

Which type of NAT involves a one-to-one mapping of private to public IP addresses?

• Static PAT

• Dynamic PAT

• Dynamic NAT

• Static NAT

In static NAT, what is the term used for the IP address assigned to the router's outside interface?

• Inside Global IP Address

• Outside Local IP Address

• Outside Global IP Address

• Inside Local IP Address

Why is static NAT considered expensive?

• It needs constant monitoring and updates

• It requires a large number of public IP addresses for one-to-one mapping

• It uses more bandwidth than other types of NAT

• It involves complex configuration processes

What is a key limitation of static NAT?

• It is only suitable for small networks

• It requires manual configuration of ports

• It does not allow for dynamic IP address assignment

• It can only be used with TCP protocols

What is the difference between static NAT and dynamic NAT?

• Static NAT uses dynamic IP address assignment, while dynamic NAT uses static assignment

• Static NAT requires manual port configuration, while dynamic NAT does not

• Static NAT is used for small networks, while dynamic NAT is for large networks

• Static NAT involves a fixed mapping of IP addresses, while dynamic NAT allows for dynamic assignment
