LFCS Networking Practice Question
A system administrator needs to configure a network bond on a Linux server using NetworkManager. Which TWO steps are required to create a functional bond interface?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use 'nmcli connection add type bond ifname bond0' to create the bond interface.
The two required steps are creating the bond connection and attaching slave interfaces. The bonding kernel module is usually loaded automatically. Setting the bond mode and IP address can be done later, and the slave interfaces do not need to be down.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the bond mode to 'balance-rr' in the connection profile.
Why it's wrong here
Setting the bond mode is optional; the default mode works for basic functionality.
- ✗
Load the bonding kernel module using 'modprobe bonding'.
Why it's wrong here
The bonding module is typically loaded automatically by NetworkManager when needed.
- ✓
Use 'nmcli connection add type bond ifname bond0' to create the bond interface.
Why this is correct
Creating the bond connection is the first required step.
- ✓
Use 'nmcli connection add type ethernet ifname eth0 master bond0' to attach a slave.
Why this is correct
Attaching slave interfaces is required to make the bond functional.
- ✗
Ensure that the slave interfaces are down before adding them to the bond.
Why it's wrong here
Slave interfaces can be added while up; NetworkManager handles the configuration.
