Dear All Cisco experts,

I have just passed my CCNA exam. Now i want to prepare and sit for CCNA Voice or Security before Dec 2014.

Can i know which one has better career prospect (Voice vs Security)?  rclxub.gif
For exam preparation:

For CCNA i use Cisco Packet Tracer and read the book (cert guide).

Can anyone share with me how to prepare on the CCNA Voice/Security exam?  icon_question.gif

Can i use Cisco Packet Tracer? Or better use GNS3?

Do i really need to have real Voice equipment to practice in order to pass the exam?

Or can just read and do simulation practice?  sweat.gif

All opinion/suggestions are welcome

Thank you.

Have a great day.  smile.gif
