Is the CCIE still relevant? Are CCNA, CCNP and CCIE certs even worth it? Surely SDN and Network Automation are replacing certifications? The CCIE is no longer worth it as networks will be automated. Right? With SDN and network automation, there is no longer a need for CCNA, CCNP or CCIE certifications. Jeff McLaughlin, Director, Technical Marketing at Cisco tells us his thoughts on this. He also explains SD-Access (SDA) and other Cisco SDN technologies. Menu: Who is Jeff: 00:24 The CCIE is dead: 2:20 Is Networking still a good career?
