問題文
After adding a second network card to a virtualization host, the two interfaces swap names between reboots and the wrong one ends up carrying storage traffic. Which mechanism gives each card a stable name?
選択肢
- Loading the driver for the storage-facing card first, since the kernel assigns names in the order the drivers finish initializing, and the boot order fixes which card becomes the first interface.
- Recording the current names in the mount table so that the boot process can read them back, which is the standard way of pinning interface names because the mount table is processed before any network device is initialized.
- A device manager rule that matches an attribute unique to the card, such as its hardware address, and assigns the name from that match.
- Disabling the second card and configuring both addresses on the first one.
