  Understanding the associated production of jets and vector bosons is of
paramount importance for the top quark physics, for the Higgs boson and for
many new physics searches. In this contribution, recent measurements of
W/Z+jets and Z+b-jets processes by the D0 experiment are presented. The
measurements are compared to theoretical predictions from next-to-leading order
(NLO) perturbative QCD calculations where available, and to several Monte Carlo
model predictions.
