Question 3 of 55

How do virtual networks that are natively isolated from each other provide support for overlapping IP address in a multi-tenant environment?

Answer

Suggested Answer

The suggested answer is A.

Network virtualization eliminates the need for IT to change IP addresses. With virtual networks natively isolated from each other and from the underlying physical hardware, network virtualization supports overlapping IP addresses in a multi-tenant environment. That means the same IP addresses can be used in separate enterprise networks that run over the same physical infrastructure.
