No serialization, no wait/notify for
thread (as I remember), but not sure... because you may get a legacy version of the IZ0-851 exam.
Not much about OO design like cohesion and coupling because these design principles are too subjective.

My tip : study to whole book just in case you get some legacy set of questions.
