CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux administrator is troubleshooting a server with two network interfaces, eth0 and eth1, configured as a bonded interface named bond0. The server is connected to a basic, unmanaged network switch. Users report slow performance and intermittent connection drops to the server. The administrator inspects the bonding configuration file and finds the line BONDING_OPTS="mode=802.3ad miimon=100". What is the most likely cause of the network issues?

  • The Maximum Transmission Unit (MTU) is mismatched between the bond0 interface and the slave interfaces.

  • The server should be configured in active-backup mode, which has better performance than 802.3ad.

  • The 802.3ad mode requires Link Aggregation Control Protocol (LACP) support on the switch, which an unmanaged switch cannot provide.

  • The miimon=100 setting is too aggressive and is causing false link-down events.
