Explanation

To configure active/passive failover with Dedicated Interconnect on Google Cloud, you must control both egress (Google → on-premises) and ingress (on-premises → Google) traffic paths. For egress, Google Cloud uses the Cloud Router's advertised route priority: a higher priority value makes a route more preferred. Setting the active connection's BGP session priority to 200 (A) while leaving the passive connection at the default (100) ensures Google prefers the active path for outbound traffic. For ingress, on-premises routers use BGP MED (Multi-Exit Discriminator) to influence which path traffic takes into Google: a lower MED is preferred. Advertising a lower MED on the active connection (C) makes on-premises routers prefer sending traffic through it. Option D (lower MED on passive) is backwards. Option E (priority 200 on passive) would make passive preferred, inverting the requirement.
