Yes it is. There is potentially one IRR for every change of sign in the cash flows.
So for example, if the cash flows are:
0 (10,000) 1 20,000 3 (8,000)
The flows change from negative to positive, and then from positive to negative, so 2 changes of sign and therefore possibly (but not necessarily) two IRR’s.
However you could not be expected to calculate the IRR’s in this case in the exam.
