SUN MICROSYSTEMS PAPER - DEC 2005

60 questions 60 marks Everything is multiple choices. BEWARE OF NEGATIVE MARKING.

Section 1: Operating Systems 20 questions

Section 2: Technical Programming 25 questions

Section 3: Aptitude 15 Questions

Section 1: Operating Systems

Study all the UNIX commands & some basic networking concepts like DHCP, Dynamic NAT, RARP, ARP, UDP,

DNS, and UNIX: Grep, sed, basic pearl program whose o/p is to be predicted. Pipes. You can expect some

nasty & tricky questions! But this section is cool not to worry too much.

Section 2: Programming part

C programs & Java programs. The programs seems to be easy but bcoz of the Negative marking (0.5) we have to

be very clear. No bluffing ok! The programs are easy. Programs were on Fork, PID, Basic C syntax, Basics of

Java, Exception handling, Inheritance, Strings, Cast conversion, Object linking etc

Section 3: Aptitude

Most of the questions can be found from other placement papers like Sonata, TCS, Caritor. Nothing to worry much.

But again you have to be very confident about the answers.

The cut-off marks are not told & will be decided by the evaluators at that time. Only 3 out of some 50 candidates

got through. The next rounds are technical interview followed by HR interview. This interview call was purely on

referral basics. So not much competitors & really a good chance of getting thru! Do well & good luck!

1. Flow chart problem [Satyam]

Let the value of N be 10

divide N by 10 to give quotient (Q) remainder(R)

diff=R-Q
