A Debian 10 server needs a persistent static route to 10.99.0.0/16 via 192.168.1.1 on interface ens4. The system uses ifupdown. Which configuration should be added to /etc/network/interfaces?

post-up ip route add 10.99.0.0/16 via 192.168.1.1

up ip route add 10.99.0.0/16 via 192.168.1.1 dev ens4

static_routes="10.99.0.0/16 via 192.168.1.1"

route 10.99.0.0/16 via 192.168.1.1

A RHEL 9 server has two NICs: eno1 (connected to the corporate network 10.0.0.0/24) and eno2 (connected to a DMZ 192.168.1.0/24). Both interfaces are managed by NetworkManager. The admin needs to ensure that traffic to 10.0.0.0/24 always uses eno1 and traffic to 192.168.1.0/24 always uses eno2, even after reboot. The default gateway is on eno1. Which configuration approach best achieves this?

Set ipv4.route-metric to 100 on eno1 and 200 on eno2, and add explicit static routes for both subnets

Use ip route add commands in /etc/rc.local

Set ipv4.never-default to yes on eno2 and rely on the kernel's automatic route selection

Disable NetworkManager and configure both interfaces using /etc/network/interfaces

Which of the following tasks can be performed using nmtui?
