  We report two microlensing planet candidates discovered by the KMTNet survey
in $2017$. However, both events have the 2L1S/1L2S degeneracy, which is an
obstacle to claiming the discovery of the planets with certainty unless the
degeneracy can be resolved. For KMT-2017-BLG-0962, the degeneracy cannot be
resolved. If the 2L1S solution is correct, KMT-2017-BLG-0962 might be produced
by a super Jupiter-mass planet orbiting a mid-M dwarf host star. For
KMT-2017-BLG-1119, the light curve modeling favors the 2L1S solution but
higher-resolution observations of the baseline object tend to support the 1L2S
interpretation rather than the planetary interpretation. This degeneracy might
be resolved by a future measurement of the lens-source relative proper motion.
This study shows the problem of resolving 2L1S/1L2S degeneracy exists over a
much wider range of conditions than those considered by the theoretical study
of Gaudi (1998).
