You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

A network engineer confirms that STP is enabled on all switches in the network. An edge switch is not sending or receiving configuration BPDUs, although it appears that everything is functioning correctly in the network.
Which design explanation is true?

A network design shows two routers directly connected to an Ethernet switch using optical connections.
There is an OSPF adjacency between the routers. In this design, which solution will ensure that interface down detection is reported as quickly as possible to the IGP?

As part of the network design, ACME Corporation requires the ability to export IPv6 information to better manage its network. Which version of NetFlow records is required to export this information?

Which two techniques are used in an OSPF network design to slow down the distribution of topology information caused by a rapidly flapping link? (Choose two.)
