The Exam Content

Overview: The content of the exam is generally outdated and is heavy on several chapters, largely omitting several others.

The examination tests general knowledge of networking, basic attacks/threats and defensive measures.  It is NOT comprehensive.  It is generally a definition and functionality knowledge assessment.  More than a few questions seem to have sourced from CompTIA Security+.  In fact, this seems to be a fork of that certification both in content and testing topics.


Some topics are lightly covered in the exam:

  • Network monitoring
  • VPN designs
  • Risk assessment
  • Incident response
  • IPS

Other areas have extraordinary focus:

  • Network controls
  • Host security
  • IDS

As with CEH, the chapters are swollen to overflowing.  You need to know to know definitions!

Note on exhibits and simulationsThere are exhibits, but very simple and they are not needed to understand the questions.

Question Quality

The quality of the questions is low, and the English language is badly abused here.  It is common to see sentence fragments and a lack of articles.  See first slide (Welcome to CND Course, not Welcome to the CND Course).

It is largely impossible to get a score higher than 90%.  Some questions just don’t make sense, are graded wrong, or have multiple correct answers.  Getting 85% means you studied as well as possible.
