CCDE Written Exam (352-001) Version 2.1

 

Exam Description

 

Cisco CCDE® Written Exam [352-001] version 2.1 is a 2-hour test with 90−110 questions that test a candidate's combined knowledge of routing protocols, internetworking theory and design principles. The exam assesses a candidate's understanding of network design in the areas of routing, tunneling, Quality of Service, Management, Cost, Capacity, and Security. This exam combines in-depth technical concepts with Network Design principles and is intended for a Network Professional with at least 7 years of experience in Network Engineering or Advanced Network Design. Product-specific knowledge including version of code, implementation and operations specific concepts is not tested on the CCDE exam. The exam is closed book and no outside reference materials are allowed.

 

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. In order to better reflect the contents of the exam and for clarity purposes, the guidelines below may change at any time without notice.
