Q

Why is NAT not needed in IPv6?​

Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.​
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​
The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.​
The end-to-end connectivity problems that are caused by NAT are solved because the number of routes increases with the number of nodes that are connected to the Internet.

A

Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​

Q

Within a production network, what is the purpose of configuring a switch with a default gateway address?

Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination.
A switch must have a default gateway to be accessible by Telnet and SSH.
The default gateway address is used to forward packets originating from the switch to remote networks.
It provides a next-hop address for all traffic that flows through the switch.
