Correct! Wrong!

"Explanation:
1: The matching lenth prefix in CIDR notation is /22.
2: The next multiple of 8 bigger than 22 is 24, which is a myltiple of 8. The third octet is intriguing.
3: Since 24-22 equals 2, the incremental is 22—or 4.
4: The third octer's increments are 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and so forth."

Your organization uses both IPv4 and IPv6 on computers spread across many sites. A firewall that implements symmetric NAT guards each location. Peer-to-peer communication must be permitted between all locations. What do need to do?

Configure a link local IPv6 address for the internal interface of the firewall.

Configure a global IPv6 address for the external interface of the firewall.

Configure the firewall to allow the use of Teredo.

Configure dynamic NAT on the firewall.

Correct! Wrong!

Explanation:
Teredo is a transitional technique used in computer networking that enables full IPv6 connectivity for IPv6-
capable sites that are connected to the IPv4 Internet but do not directly connect to an IPv6 network. One
aspect that sets it apart from other similar protocols is its ability to function even when hidden by network
address translation devices that use NAT, such home routers.
