If you want your customer's virtual systems to give protected hosts access to and from the internet, which of the following must be configured as a Public IP address?

Question

Options

• AMain IP of the Virtual Switch
• BDefault Gateway IP Address of the Virtual Switch
• CMain IP of the Customer's Virtual System
• DMain IP of the Management Virtual System
• EDefault Gateway IP Address of the Management Virtual System

• C

• D

• E

Explanation

Option C is correct because the Customer's Virtual System (VS) acts as the security gateway between the protected (internal) hosts and the internet. Its Main IP is the externally-facing address that internet traffic flows through - if it isn't a public IP, return traffic from the internet has no routable address to reach, breaking connectivity entirely.

Why the distractors are wrong:

• A & B (Virtual Switch IPs): Virtual Switches are internal Layer 2/3 components that route traffic between virtual systems - they never directly face the internet and require only private addressing.
• D (Main IP of the Management VS): The Management VS handles administrative control-plane traffic on a dedicated management network, not customer data-plane internet traffic.
• E (Default Gateway of Management VS): Same reasoning as D - this is a private management-network address with no role in customer internet connectivity.

Memory tip: Picture the Customer's Virtual System as the building's "front door address" - just as a building's street address must be publicly known so mail can arrive from anywhere, the Customer VS Main IP must be a public IP so internet traffic can find its way back to your protected hosts.
