An administrator must use Cisco FMC to install a backup route within the Cisco FTD to route traffic in case of a routing failure with primary route. Which action accomplish this task?
Options
- AInstall the static backup route and modify the metric to be less than the primary route
- BUse a default route in the FMC instead of having multiple routes contending for priority
- CConfigure EIGRP routing on the FMC to ensure that dynamic routes are always updated
- DCreate the backup route and use route tracking on both routes to a destination IP address in the

Why each option
To install a backup route within a Cisco FTD for failover purposes, the administrator must create the backup static route and then implement route tracking on the primary route. This ensures the backup route becomes active only when the primary route's path becomes unreachable.
Installing a backup route with a metric *less* than the primary route would make it the preferred route, causing it to be used over the primary route, which is contrary to the purpose of a backup.
A default route provides a path for traffic to unknown destinations and does not provide specific failover for a primary route to a known specific destination.
While EIGRP is a dynamic routing protocol that can provide redundancy, it is configured on the FTD devices themselves, not directly 'on the FMC,' and the question implies a static route failover scenario, making route tracking the more direct answer.
Creating a backup static route and coupling it with route tracking (e.g., using an IP SLA monitor) on the primary route is the standard method for achieving static route failover in Cisco FTD. When the tracked object associated with the primary route fails, the primary route is removed from the routing table, allowing the backup route to become active and take over traffic forwarding.
