In general I find that the older CSSA exams don't really follow the syllabus enough and have very ambiguous questions but I'll give it a go now since I have that paper.
1. B
2. A or B, I'd say A (ie: He could use Microsoft Access to make a database and store the info)
3. I think it's C, although the question is a bit ambiguous IMO. It's definitely not D.
4. A
5. C (this is a stupid question, they obviously do not seem to understand the difference between reverse engineering and decompilation).
6. D
7. C (I think)
8. D
9. A
10. C
11. D
12. C
13. B
14. Another ambiguous question. Both A and C should be legitimate answers.
15. A
16. B
17. B
18. D
19. B
20. C
Please post your solutions for the multiple choice. I'd like to know if I've made any mistakes.
