Hello Vanniarajan,
You would b well served to avoid the v4 and go directly to the v5 product certifications as they are, IMHO, vastly superior. The practice
test are available for free at certify.torolab.ibm.com. Are you thinking about the developer or the admin type certifications? I have both.
Best Regards,
