The exam is closed book and no outside reference materials are allowed.
An Evolving Technologies section is included in the Written exam only. It will enable candidates to bridge their core technology expertise with knowledge of the evolving technologies that are being adopted at an accelerated pace, such as cloud, IoT, and network programmability.
The Cisco CCIE® Service Provider Lab Exam is an eight-hour, hands-on exam which requires a candidate to configure, diagnose, and troubleshoot a series of complex network scenarios for a given specification based on dual stack solutions (IPv4 and IPv6). Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE lab exam. The candidate will not configure all end-user system; however, the candidate is responsible for all devices residing in the network.
The following topics are general guidelines for the content likely to be included on the exam. However, other related topics may also appear on any specific delivery of the exam.
