Water-plant IT keeps a duplicate physical switch stack per agency for isolation. Which traditional pattern does virtual networking replace?
Select an answer to reveal the explanation.
Short Explanation
A second switch stack per agency is buying a second water main when valves would do. Logical segments and policy isolate traffic on shared hardware. The plant should not purchase a whole extra fabric just to keep agencies apart.
Full Explanation
Traditional isolation often meant a dedicated physical switching fabric per department, which multiplies cost and operations. Virtual networking provides logical isolation—separate segments, routing, and firewall policy—on shared hypervisor and underlay hardware. Horizon pods and extra Carbon Black instances do not replace that network isolation. NSX-T does not require a duplicate physical fabric per tenant.
