13. Practical task.

14. Discussion and review. Recaps.

The basic objective of "Professional Networking - Core Networking" is to deepen the practical administration of computer networks. It enlarges the knowledge on enterprise core networks - including network design, installation, and configuration of network devices. The students who successfully complete the subject acquire the knowledge and skills required for ENCOR part of the Cisco CCNP (Cisco Certified Network Professional) certification. The certification can be obtained in authorized examination centers, independently from the University education.

Oktatási módszertan

The course is realized through 4 hours of laboratory work per week, where students complete the assigned tasks using real networking devices or a simulator program. In the classes, we provide special time to review new knowledge, explain certain parts in more detail, and clarify questions that may arise. Acquired skills and knowledge: a) VLAN design and management b) Management of network connection and element redundancy c) Advanced details and configuration of IGP routing d) Basics and configuration of EGP routing e) Configuration of tunnels f) Knowledge of operation and security settings in wireless networks g) Configuration of solutions that increase the security of the network and its components h) Advanced knowledge of modern network administration techniques

General rules

Requirements: 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 task: At 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 this task 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 task 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: - Additional possibilities: 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 task: The practical task 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).
