The configuration is not working correctly because the IP SLA operation has not been scheduled to start. The correct configuration should include the 'ip sla schedule' command to start the IP SLA operation right away. Option A includes the 'ip sla schedule 2 life forever start-time now' command, which schedules the SLA operation to run indefinitely starting immediately. This ensures that the IP SLA is active and can properly track the reachability of the 10.1.1.1 address. Additionally, the static route is configured with the track option, meaning it will be removed if the tracked object indicates that 10.1.1.1 is unreachable.
