CompTIA Linux+ XK0-006 (V8) Practice Question

While reviewing an Ubuntu Server's network configuration you find three Netplan definition files:

  • /lib/netplan/00-default.yaml
  • /etc/netplan/50-vm.yaml
  • /run/netplan/50-vm.yaml

Each file configures the same interface (ens192). After editing /lib/netplan/00-default.yaml to set a new static address you run "sudo netplan apply", but the system still boots with the old address.

According to Netplan's file-processing rules, which statement best explains why the change was ignored?

  • The definition in /run/netplan/50-vm.yaml is processed last (highest directory priority and later filename), so its settings override those in /lib/netplan/00-default.yaml.

  • Netplan skips YAML files whose names start with 00, causing your edited file to be excluded from processing.

  • Because Netplan keeps the first file it encounters, the earlier /etc/netplan/50-vm.yaml configuration took precedence over all others.

  • /lib/netplan files are ignored once the system has booted, so editing 00-default.yaml cannot influence a running configuration.
