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

The video tutorial explains Network Address Translation (NAT), a method to provide Internet access to devices with private IP addresses. It covers different types of NAT, including static and dynamic NAT, and Port Address Translation (PAT). The tutorial also distinguishes between source NAT, which translates the source IP address, and destination NAT, which translates the destination IP address. It highlights that both source and destination NAT can be applied simultaneously to facilitate communication between local networks and the outside world.

What is the primary function of NAT in a network?

• To encrypt data packets for security

• To block all incoming and outgoing traffic

• To provide internet access to hosts with private IP addresses

• To assign public IP addresses to all devices

Which type of NAT is typically used for outgoing connections?

• Dynamic PAT

• Static NAT

• Dynamic NAT

• Static PAT

What does PAT stand for in the context of NAT?

• Private Address Translation

• Protocol Address Translation

• Port Address Translation

• Packet Address Translation

What happens to the source IP address in a packet when source NAT is applied?

• It remains unchanged

• It is encrypted

• It is replaced with another IP address

• It is deleted

Can source NAT and destination NAT be applied at the same time?

• Yes, they can be applied simultaneously

• No, they cannot be applied together

• Only in static NAT

• Only in dynamic NAT
