The correct answer is A. Enable LACP on the network switch ports. See the full explanation below for the reasoning.
Question
A system administrator has configured a VIO Server to use a Shared Ethernet Adapter (SEA) that is built from a linkaggregation of gigabit Ethernet adapters. The administrator has determined that not all ports in the link aggregation are being used. The administrator verifies that aggregation mode for the Etherchannel is 802.3ad, which is the corporate standard, and that the Ethernet ports on the server are connected to the correct ports on the network switch. The administrator then runs the entstat command against the SEA (ent28), and receives the following output. $ entstat -all ent28Real Adapter:

Options
- AEnable LACP on the network switch ports.
- BSelect the correct mode for the Etherchannel.
- CEnable Jumbo Frames on the physical adapters.
- DSelect the correct hash_mode for the Etherchannel.
