1 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 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.
2 When should the command no auto-summary be used?
#with RIP version 2, when discontigous networks exist
3 Refer
to the exhibit. What must an administrator do on R3 to ensure that
update packets are sent with subnet mask information?

#separated from the rest of the hierarchical group by another network
