Question #1

- D. should never be taken into account when choosing priorities
Answer: C
Question #2
Which statement is true about the argv element of the CORBA::ORB_init operation?
- A. If the ORB CANNOT map the argv element integers onto the native priority scheme, then it adjusts the
range as appropriate. - B. If the argv element string does NOT conform to the specification constraints, then a BAD_PARAM
system exception is raised. - C. There is no minimum range for the low and high priorities expressed in the ORB_init argv element.
- D. The two <short> positive integers representing the low and high ends of the priority range may be
expressed in any order.
