A network administrator is configuring IPv4 static routes on router R1 to reach destination network . The primary path must forward traffic to the next-hop IP address . A secondary path must act as a floating static backup route using the point-to-point interface Serial0/1/0, forwarding traffic only if the primary path becomes unavailable. Which TWO commands must be configured on router R1 to achieve this objective?
- ip route 10.88.0.0 255.255.0.0 192.168.50.2Answer
- ip route 10.88.0.0 255.255.0.0 Serial0/1/0 130Answer
- Cip route 10.88.0.0 255.255.0.0 Serial0/1/0 1
- Dip route 10.88.0.0 0.0.255.255 192.168.50.2
Answer
The correct configurations are the command defining the primary static route using next-hop IP address 192.168.50.2 with the default administrative distance of 1, and the command defining the floating static backup route via interface Serial0/1/0 with an administrative distance elevated to 130.
The primary path to is defined using the next-hop IPv4 address 192.168.50.2, which inherits the default static route Administrative Distance (AD) of 1. To configure a floating static backup route, an explicit AD value strictly greater than the primary route's AD (such as 130) must be appended at the end of the command string. Additionally, point-to-point interfaces like Serial0/1/0 are valid exit interface choices for static routing.
