Which of the following commands could you use to accomplish this task? (Select two.) route insert 195.156.76.0 netmask 255.255.255.0 dev eno32 ip route add 195.156.76.0/24 dev eno32 route add 195.156.76.122 netmask 255.255.255.0 ip route add 195.156.76.0/16 dev eno32 route add -net 195.156.76.0 netmask 255.255.255.0 dev eno32 Explanation

The route add -net indicates that you are adding a route, and the target is a network. 195.156.76.0 netmask 255.255.255.0 indicates that you are routing network 195.156.76.0 with a subnet mask of 255.255.255.0, which indicates the fi rst three octets are the network address. Remember, you route networks, not hosts. dev eno32 indicates that the eno32 device is being used to fi nd the target network. The other correct answer is ip route add 195.156.76.0/24 dev eno32 . ip route add 195.156.76.0/24 indicates that you are adding the 195.156.76.0/24 network with the 24-bit subnet mask (which is the same as the 255.255.255.0 subnet mask, but you must use CIDR notation with the ip command and any of its options). dev eno32 indicates that the eno32 device is being used to fi nd the target network.

Your default gateway is 192.168.5.1, but you want this route to use gateway 192.168.7.1. Which of the following commands could you use to accomplish this task? (Select two.) ip route add 195.157.66.0/8 via 192.168.7.1 route add -net 195.157.66.0 netmask 255.255.255.0 gw 192.168.7.1

The second option is to use ip route add 195.157.66.0/24 via 192.168.7.1 . ip route add 195.157.66.0/24 indicates that you are adding the 195.156.76.0/24 network with the 24-bit subnet mask (which is the same as the 255.255.255.0 subnet mask, but you must use CIDR notation with the ip command and any of its options) to the route table. Including via 192.168.7.1 indicates that you are using 192.168.7.1 to fi nd the target network.

Which of the following commands could you use to accomplish this task? (Select two.) ip route add 11.12.13.14/24 via 201.12.3.4 route -p add 11.12.13.14 201.12.3.4 route add -net 11.12.13.14/24 gw 201.12.3.4 add route 11.12.13.14/24 gw 201.12.3.4 ip route add -net 11.12.13.14/24 via 201.12.3.4 Explanation The fi rst option is to use the route add command to add a route to the routing table. To add an entire network (versus just a host), use the -net option followed by the network address and gateway using route add -net 11.12.13.14/24 gw 201.12.3.4 . The second option is to use the ip route add command to add a route to the routing table. First, indicate the network address. Then use via to indicate the IP address of the router to which packets addressed to the remote route should be sent as follows: ip route add 11.12.13.14/24 via 201.12.3.4 References 12.2.11 Con " gure IP Addresses 12.5.2 Routing Con " guration Part 2 12.5.4 Routing Facts 12.8.6 Troubleshoot IP Con " gurations q_ip_route_add_net_lp6.question.fex

Drag a route add option on the left to the correct description on the right. Speci fi es a single host on the network. -host Installs a blocking route. reject Creates a route for the default router. default gw Speci fi es a network address. -net Keyboard Instructions Explanation The following are the correct descriptions for each listed route add option: default gw creates a route for the default router. -net speci fi es a network address. -host speci fi es a single host on the network. reject installs a blocking route.
