  With the high collision energies at the LHC, the contributions to particle
production from hard-QCD processes increase, but it remains dominated by
soft-QCD processes. Such processes challenge the theoretical models, since they
are described by non-perturbative phenomenology. A selection of the most recent
ALICE measurements of charged-particle multiplicities and the Underlying Event
will be presented, focusing on model comparisons. A summary of the current
understanding of soft-QCD processes will be discussed, evaluating possible ways
to further constrain theory.
