Choose online practice tests over pdf

I tell you this because i have suffered because of practicing from pdf files. This is an age-old method and wastes time without any good result. dbexam.com is the best choice in present times. It helped me pass the actual exam with flying colours. The site offers a platform for practising for 1Z0-821 certification exam. It has Oracle Solaris 11 System Administration Practice Questions and very similar to those of real ones. I recommend to choose this site to new-comers too.
