You want to set up two Cloud Routers so that one has an active Border Gateway Protocol (BGP) session, and the other one acts as a standby. Which BGP attribute should you use on your on-premises…
The correct answer is D. Multi-exit Discriminator. You can configure 2 different MED values for each BGP neighbor in your single on-prem router, to influence ISP(GCP)'s 2 separate routers to select which path they send traffic towards you. The lower MED value is preferred.
