B.
DB timecannot exceed the maximum number ofconcurrentsessions multiplied by the

agree with what?
agree with what ?
with the given answers
D,E
B would be right if “concurrent” was replaced by “total”
DB timecannot exceed the maximum number of concurrent sessions multiplied by the actual elapsed time for each session.
So B is wrong
So I choose D,E
but D is not clear. OK if you reduce dbtime, you can support additive sessions but you will consume again more resources…
