    **Question**:
    What is the most efficient way to configure an IP address on a Linux system with multiple network interfaces?

    **Answer**:
    The most efficient way to configure an IP address on a Linux system with multiple network interfaces is to [use the Network Manager utility](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/getting_started_with_networkmanager).

    This tool allows you to easily set up and manage your network connections on a Linux system, including assigning static IPs to multiple interfaces.

    It can also be used for troubleshooting networking related issues, such as diagnosing problems with DHCP servers or configuring VPNs.

    Additionally, Network Manager is capable of automatically detecting and connecting to WiFi networks as well as configuring advanced network settings such as DNS server addresses, default gateways, and custom routes.

    The utility can be accessed through the graphical user interface (GUI) or command line interface (CLI). With Network Manager, configuring the IP address of a Linux system with multiple network interfaces becomes much simpler.

    Alternatively, you can also use the ifconfig command to [manually configure static IP addresses in Linux](https://www.howtouselinux.com/post/linux-command-change-ip-address-in-linux) on each interface or edit your /etc/network/interfaces file to set up static IPs as well. However, this method is not as user-friendly as using Network Manager.
