A network engineer is enabling Cisco Catalyst SD-WAN Cloud OnRamp for SaaS to optimize Office 365 traffic for a remote branch. The branch has a local Direct Internet Access (DIA) circuit, but the SD-WAN administrator wants OnRamp to measure application performance and automatically steer the SaaS traffic over the best-performing path, which may be either the local DIA or a Cloud Gateway site. Which OnRamp configuration element must be defined so that a branch without a qualifying local exit can still forward SaaS traffic through a regional data center or cloud gateway that hosts the internet exit?
