Form(s) of Assessment

Portfolio Assessment

Form(s) of Assessment (additional text)

The portfolio consists of three parts.
Part 1:  Electronica, written or oral Exam (40 points) based on CCNA R&S Module 3 and 4, CCNA
            Security and WLAN specific course materiel
Part 2:  Practical Skill Test (with real hardware or simulation software (20 points)
Part 3:  Project work (40 points)

All sub-parts must be passed (>=40%) to pass the course

Conversion from 100 point scale to A-F scale according to recommended conversion table. In specific circumstances, emneansvarlig can slightly adjust the limits in the conversion table to enforce compatibility with the qualitative descriptions on the A-F scale.

It is possible for those students willing to get the voucher for getting the CCNA R&S and CCNA Security Certificates, 
do the CCNA Final Exams as an additional exam. This will not be part of the grade of this course

Grading Scale

Alphabetical Scale, A(best) – F (fail)

External/internal examiner

Evaluated by internal examiner, external examiner is used periodically (every five years, next time in 2018/2019)

The exam consists of several parts, the course responsible will define at the beginning of the course which part of the exam shall be graded by the external sensor

Alternatively to the external grading an external supervisor can evaluate the course structure, course content and the content of the exams. 

Re-sit examination

Single Parts of the exam can be re-taken again.

Highly practical skill tests and projects can only be repeated in the next study year.

Additional information

This is a cased-based course where the students will experience the learning outcome directly by developing a concept for an SME including:

  • description of business cases
  • IT-Systems and IT-Infrastructure
  • IT-Service Concept
  • Security Policy
  • Security Guidelines
  • according security measures

The IT-System and IT-Infrastructure including the security measures will be realised on real Lab Hardware in the cisco Lab. 

At the end of the course a competition shall be realised where different groups of student will defend or attack the developed enterprise networks. At the end of the competition the strategies of attackers and defenders will be discussed. Forensic methods shall be used to find out which traces the attacker and defenders left during there activities
