I would like to thank Mark Snow for all the effort and time he put into creating the CCIE Collaboration training videos. These videos contributed tremendously not only in helping me understand the CCIE collaboration exam topics and pass the lab but also in understanding the Cisco Collaboration technologies in general. I highly recommend these videos to anyone pursuing any Cisco collaboration certification (CCNA voice, CCNP voice and of course CCIE Collaboration). Mark's teaching style and skills make him one of the best Cisco Collaboration/UC instructor in industry. Thank you Mark!
