As well as updating the CCIE Data Center track, Cisco have recently updated all CCIE Written exams. A new section called “Evolving Technologies” has been added and accounts for 10% of all CCIE Written exams. The remaining 90% of the exam is made up from the core topics that are relevant to the specific track you are taking. The go-live date is July 2016.
The idea behind the update is to “enable candidates to bridge their core technology expertise with knowledge of the evolving technologies that organizations are adopting at an accelerated pace, such as cloud, IoT, and network programmability.”
