Selected Answer: C
The most effective solution to reduce the failover time in this scenario is option C, configuring Bidirectional Forwarding Detection (BFD) on the on-premises router. BFD provides rapid failure detection and is commonly used in conjunction with BGP to achieve faster failover times in network connections like AWS Direct Connect.
