Which statement is true about the VMware SD-WAN Gateway roles and assignments?
The correct answer is A. Primary Gateway cannot be used as Super gateway for Edge-to-Edge communication, even it all. Option A is correct because in VMware SD-WAN, the Primary Gateway role and the Super Gateway role are distinct and mutually exclusive functions - a Gateway designated as Primary for an Edge handles that Edge's traffic (internet breakout and VPN tunnels), but it cannot…
Question
Which statement is true about the VMware SD-WAN Gateway roles and assignments?
Options
- APrimary Gateway cannot be used as Super gateway for Edge-to-Edge communication, even it all
- BThe SD-WAN Orchestrator assigns the Gateways to the Edge automatically when it comes up
- CIf the Primary Gateway goes down. Cloud internet traffic would failover to Secondary gateway
- DThe Primarily and Secondary Gateways share the load fur both internet traffic and VPN traffic

Explanation
Option A is correct because in VMware SD-WAN, the Primary Gateway role and the Super Gateway role are distinct and mutually exclusive functions - a Gateway designated as Primary for an Edge handles that Edge's traffic (internet breakout and VPN tunnels), but it cannot simultaneously serve as a Super Gateway, which is the specialized role required to relay Edge-to-Edge (spoke-to-spoke) traffic, regardless of conditions.
Option B is wrong because Gateway-to-Edge assignments are not automatic - administrators explicitly configure Gateway assignments within SD-WAN profiles via the Orchestrator; the Orchestrator applies the configured assignment, it does not auto-discover and assign Gateways dynamically.
Option C is wrong because when the Primary Gateway fails, the Secondary Gateway takes over VPN/overlay traffic, not specifically "cloud internet traffic" - internet-bound traffic behavior depends on the configured traffic policies (local breakout, backhaul, etc.), making this an oversimplification that is inaccurate.
Option D is wrong because Primary and Secondary Gateways operate in an active-passive (primary-backup) model, not active-active load sharing - the Secondary sits idle for failover, not simultaneously splitting internet and VPN load with the Primary.
Memory tip: Think of SD-WAN Gateway roles like job titles - a Primary Gateway is an "Edge's personal assistant" (handles that Edge's traffic), while a Super Gateway is the "inter-office coordinator" (routes Edge-to-Edge). One person can't hold both titles at the same time.
