copy running-config startup-config*

2 
Which IPv4 header field is responsible for defining the priority of the packet?​
traffic class
flow label

3 
When connectionless protocols are implemented at the lower layers of the OSI model, what are usually used to acknowledge the data receipt and request the retransmission of missing data?
Transport layer UDP protocols
upper-layer connection-oriented protocols*

4 
Why is NAT not needed in IPv6?​
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​*
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.
Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.​
The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.​
