04. What is the likely impact of moving a conventional company architecture to a
completely converged network?
Local analog phone service can be completely outsourced to cost-effective
providers.
The Ethernet VLAN structure is less complex.
A shared infrastructure is created resulting in a single network to manage.
QoS issues are greatly reduced.
