ccna discovery 4 chapter 6 v4.0

A network engineer researched whether there are mechanisms available to help with
the
transition from an IPv4 addressing structure to IPv6. What three options did the
engineer find?(Choose three.)
A protocol translation mechanism allows communication between the IPv4 and IPv6
networks.
A packet analyzer determines the addressing structure and converts it to the
appropriate IPv4 or IPv6 scheme.
New Core devices that support IPV6 must be purchased.
A protocol converter changes IPv4 packets into IPv6 packets and vice versa.
A dual-stack network design allows both IPv4 and IPv6 addressing to be used on all
network devices.
Tunneling allows IPv4 packets to be encapsulated so that they can traverse IPv6
networks and vice versa.

When should the command no auto-summary be used?
with RIP version 1, to enable classless routing
with RIP version 2, to enable classless routing
with RIP version 1, when discontigous networks exist
with RIP version 2, when discontigous networks exist

Refer to the exhibit. What must an administrator do on R3 to ensure that update
packets are sent
with subnet mask information?
Add the commands:
R3(config-router)# auto-summary
R3(config-router)# no version 2
Add the commands:
R3(config-router)# version 2
R3(config-router)# no auto-summary

Change the network statement on R3:
R3(config)# network 10.10.4.0
Add the command:
R3(config)# ip route 0.0.0.0 0.0.0.0 s0/0
