  Simulations of supersymmetric field theories with spontaneously broken
supersymmetry require in addition to the ultraviolet regularisation also an
infrared one, due to the emergence of the massless Goldstino. The intricate
interplay between ultraviolet and infrared effects towards the continuum and
infinite volume limit demands careful investigations to avoid potential
problems. In this paper -- the second in a series of three -- we present such
an investigation for ${\cal N}=2$ supersymmetric quantum mechanics formulated
on the lattice in terms of bosonic and fermionic bonds. In one dimension, the
bond formulation allows to solve the system exactly, even at finite lattice
spacing, through the construction and analysis of transfer matrices. In the
present paper we elaborate on this approach and discuss a range of exact
results for observables such as the Witten index, the mass spectra and Ward
identities.
