    6. Pre-requisites

    It is recommended that Computer Network Operations in Practice I, VIHIAV39 be completed in advance, or a preliminary study in accordance with the CiscoCCNAv7 ITN semester.

    Due to a topic conflict, the subject can only be taken by those who have not previously completed the following subjects: VIHIAV97, VIHIBA01, VIHIBB03, VIHIBB02.

    7. Objectives, learning outcomes and obtained knowledge

    The basic objective of "Administrating Computer Networks I." is to introduce the practical administration of computer networks - including network design, installation, and configuration of network devices. 
    This subject gives the basics of "Administration Computer Networks in Practice II." (VIHIAV42) subject, thus providing adequate theoretical and practical knowledge and the way of its direct application. The students who successfully complete the subject acquire the knowledge and skills required for the Cisco CCNA (Cisco Certified Network Associate) certification. The certification can be obtained in authorized examination centers, independently from the University education.

    g)    Implementation of network monitoring and troubleshooting

    h)    Knowledge of modern network administration techniques

    9. Method of instruction

    The course is realized through 4 hours of laboratory work per week, where the acquired theory is applied in practice. Therefore, students have to prepare week-by-week for the laboratory work at home, using mostly the online available material.

    10. Assessment a. during the semester:
    • Participation: The participation at the laboratory classes is obligatory. They can be missed up to two times (counting 11 teaching weeks and 4x45 minute long laboratory classes a week, a minimum of 82% participation is required). The absences need to be replaced.
    • Entry tests: Preliminary preparation will be checked at the beginning of each laboratory class. The participation requires a sufficient level of knowledge. If a student fail this test, the laboratory work can not be started, and it is administrated as a missed class participation, and it has to be replaced. The preliminary preparation is checked on the 70% of the weeks (max. 10 times) in form of entry tests.
    • Practical tasks: At the middle and the end of the semester, a complex practical exercise has to be solved in the place and time of the class. It is required to solve these tasks at a sufficient level. The practical tasks can be recapped as described in the "Recaps".
    • Midterm test: During the semester the writing of a written examination is required at a sufficient level. This is done in the place and time of the class. The midterm test can be recapped as described in the "Recaps".
    The midterm test and the practical tasks are evaluated in percentage results. When the above conditions are satisfied, the grade is determined according to the mean value of the midterm test and the practical tasks results. The grade is calculated using the following ranges:
    0-49% fail (1)
    50-65% satisfactory (2)
    66-76% medium (3)
    77-87% good (4)
    88-100% excellent (5)

    b. during the exam period: -

    11. Recaps
    • Participation and entry tests: maximum two missed lessons (due to absences or insufficient preparation) can be replaced at a dedicated date (during the semester, or in the replacement week). (3 or more absences can not be replaced, thus in this case the subject can not be accomplished.)
    • Practical tasks: One of the practical tasks can be replaced in the designated replacement time (during the semester or the replacement week).
      Midterm test: The midterm test can be replaced in the designated replacement time (during the semester or the replacement week).
    12. Consultations If required, we provide a consultation opportunity at an agreed time.
