Selected Answer: D
You successfully enabled MACsec on your Cloud Interconnect connection and on your on-premises router, but the MACsec session displays that it is operationally down on your Cloud Interconnect connection links. The issue could be caused by one of the following: The active keys on your on-premises router and Google's edge routers don't match. A MACsec protocol mismatch exists between your on-premises router and Google's edge router. https://cloud.google.com/network-connectivity/docs/interconnect/how-to/macsec/troubleshoot-macsec
