  We continue the study of Rokhlin entropy, an isomorphism invariant for
probability-measure-preserving actions of countable groups introduced in the
previous paper. We prove that every free ergodic action with finite Rokhlin
entropy admits generating partitions which are almost Bernoulli, strengthening
the theorem of Ab\'{e}rt--Weiss that all free actions weakly contain Bernoulli
shifts. We then use this result to study the Rokhlin entropy of Bernoulli
shifts. Under the assumption that every countable group admits a free ergodic
action of positive Rokhlin entropy, we prove that: (i) the Rokhlin entropy of a
Bernoulli shift is equal to the Shannon entropy of its base; (ii) Bernoulli
shifts have completely positive Rokhlin entropy; and (iii) Gottschalk's
surjunctivity conjecture and Kaplansky's direct finiteness conjecture are true.
