Well, this morning I have passed the 1ZO-048 RAC expert exam.
Let me reveal about my preparations before my mail box gets filled by hundreds of mails asking me to provide documents and etc stuff. For me, Oracle RAC documentation, Oracle university (RAC course) material and of course the extensive production practice knowledge of RAC certainly helped me a lot to prepare and pass this exam. I am sorry, I can't offer anything more than this.
After the exam, a small thought comes into my mind. Since this exam comes under EXPERT category, I thought, it would have been more better doing a day practical lab exam than simply doing the multiple choice questioning exam.
Have nice time,
