Chess Board Coverage Problem

Problem

My schoolmate @SCP-D9527 asks: Is it possible to cover a chess board with a standard piece set (excluding pawns) of the same color? Here, "to cover" means that each grid is either under attack or is occupied by some pieces.

Answer

It is possible.

FEN code: R7/2B5/2B2K2/8/3Q4/6N1/8/N6R w - - 0 1
