Which statement correctly describes a requirement when integrating a Secure Internet Gateway (SIG) with an SD‑WAN Edge device?

A Cisco Umbrella organization ID is essential for integrating a Secure Internet Gateway (SIG) with an SD-WAN Edge device because it uniquely identifies your Umbrella account and allows the SD-WAN device to establish secure tunnels and forward traffic to the correct Umbrella cloud instance for security inspection. Without this ID, the SD-WAN device cannot properly authenticate and connect to the Umbrella service. "Based on routing or policy, all customer internet traffic must be forwarded to the SIG" is incorrect because while a SIG is used for internet traffic, it's not a strict requirement that all internet traffic must go through it; selective forwarding based on policy is common. "Credentials for a smart account are required" is incorrect; while smart accounts are used for licensing and device management, they are not directly used for establishing the SIG tunnel itself. "Attached to SIG tunnels, trackers monitor the respective SIG endpoints" is incorrect as trackers are generally used for monitoring reachability of internal network resources, not specifically SIG endpoints.
