Explanation

In a Standard VSX configuration, each Virtual System (VS) is positioned between an external routing layer and a protected internal network. Option C is correct because each VS requires one virtual interface toward the External Virtual Router or Virtual Switch (which handles external traffic routing across the VSX platform) and one physical interface toward the protected internal network it is defending - this two-interface model is fundamental to how VSX segments traffic between virtual firewalls.

Why the distractors are wrong:

• A & D both mention the Management Virtual System, which handles VSX administration - it is not part of each VS's standard data-path interface pair.
• B references a physical interface to the protected network but pairs it with an incomplete/incorrect second interface, missing the EVR/EVS connection.
• E describes a connection to a router on the external network directly, which confuses the physical external router with the internal VSX construct (the EVR/EVS) that each VS actually connects to.

Memory tip: Think of each Virtual System as a "sandwich" - the External Virtual Router/Switch is the top slice (virtual, facing outward) and the physical interface to the protected network is the bottom slice (real, facing inward). The VS is always in the middle of those two layers.
