CCIE Security LAB 

Exam Description

The CCIE Lab exam is an eight-hour, hands-on exam which requires you to configure and troubleshoot a series of complex networks to given specifications. Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE lab exam.

DIAG:1 hour

the act or process of identifying the root cause

TS: The Troubleshooting module is 2 hours. If desired, candidates can extent the Troubleshooting module's time by borrowing up to 30 min from the Configuration module. Note, the total Configuration module time will be reduced by the extra time spend in the Troubleshooting module (if any, up to 30 min). If candidates finish the Troubleshooting module early, the unused Troubleshooting module’s time will be added to the Configuration module’s time, ensuring a total lab exam time of 8 hours. 


The Configuration module provides a setup very close to an actual production network having various security components providing various layers of security at different points in the network. Though the major part of the module is based on virtual instances of the Cisco security appliances, the candidate may be asked to work with physical devices as well. At the beginning of the module, the candidate has full visibility of the entire module. A candidate can choose to work in the sequence in which the items are presented or can resolve items in whatever order seems preferable and logical.
