A large company has just merged with yours. This organization has recently converted its internal network from IPv4 addressing to IPv6 to support a number of new network applications that required it. You must now begin to plan for IPv6 support on your own internal network. You are creating training materials for your junior networking staff. Which of the following features is built into IPv6 that was not required in IPv4?

1. Classless Inter-Domain Routing (CIDR)

2. IP Security through the use of IPSec

3. Network address translator (NAT)

4. Loopback IP addressing

Your IT manager wants you to link four divisions of the company through a ring of eight unidirectional cross-forest trusts. He uses this reasoning: If multiple forest trusts are established, authentication requests made in any domain of any forest can pass through multiple forest trusts, hence multiple Kerberos domains, on their way to their destination. Why is he wrong?

1. Although each cross-forest trust is transitive at the forest level, where all domains in both forests can authenticate, they are not transitive at the federated forest level as he suggests. The trust path cannot include more than one cross-forest trust.

2. Cross-forest trusts are not transitive, and will not allow pass-through authentication.

3. To create a mesh trust relationship between four forests, you need only four cross-forest trusts.

4. Cross-forest trusts are bidirectional, so only three trusts are needed to link all four forests. Completing the...
