INTERVIEW QUESTIONS OPERATING SYSTEMS SOLARIS DETAILS

Question: What are the main differences between solaris 10 and 9?

Answer: The main difference in solaris 9 & solaris 10 is "SMF(Solaris Management Facility)".
In solaris 9, if any service goes down then we should restart all services this is the disadvantage.
But in solaris 10,if any service goes down then that particular service we can select and enable it instead of restarting all services.
