...It has been such a wonderful experience to be part of the Cisco evolution. Since the very beginning, our Cisco academies received a direct impact of great responsibility to prepare professionals in each certification path where each of those devices have taken an important role in the design, implementation and maintenance concepts as well against networking security threats. It's a way to remember our curricular evolution since the first CCNA 2.0 version based in the series 2500 up to the present. Thank you, for such excellent key note bringing new achievements in the networking growth leadership in response to our customers needs. Warm greetings and my respects from Puerto Rico.
