Trey Research is an innovative research organization that prides itself on being at the forefront of technology. The company currently has 82 client computers all running Windows Vista Ultimate. All its servers—including its domain controllers—have recently been upgraded to Windows Server 2008 R2 Enterprise. Trey’s site consists of two buildings linked by a fiber optic cable. Each building has its own VLAN, and Trey’s peripheral zone is on a separate VLAN. All Trey’s clients receive their IPv4 configurations through DHCP, and the 80:20 rule is used to implement failover if a DHCP server fails.

All servers and router interfaces are configured manually, as are the company’s network printers and network projectors. Trey has a Class C public IPv4 allocation and sees no need to implement NAT. It uses a network management system based on SNMP. It uses a number of high-level graphics applications in addition to business software and the Microsoft Office 2010 suite. The company wants to introduce IPv6 configuration and access the Internet. It has verified that its provider and all its network hardware fully support IPv6. Which of the following are likely to form part of Trey’s IPv6 implementation plan? (Choose all that apply.)

A. Trey is likely to adopt a dual-stack transition strategy.

B. Trey is likely to adopt a configured tunneling transition strategy.

C. Trey is likely to configure its internal network hosts with unique-local unicast addresses.

E. Trey needs to ensure that its servers and clients support IPv6.

F. Trey needs to ensure that its network projectors and network printers support IPv6.

G. Trey needs to ensure that its network management system is compatible with IPv6.

H. Trey needs to ensure that its graphic applications are compatible with IPv6.
