Linux-LPI - LPIC-3 (305: Virtualization und Containerization)

Classroom Schulung | Deutsch | Anspruch

Schulungsdauer: 5 Tage

Ziele

Die fünftägige Schulung zielt darauf ab, die Teilnehmer gezielt auf die Prüfung zur LPIC-3-Zertifizierung 304 Virtualisierung und Hochverfügbarkeit vorzubereiten. Der Schwerpunkt liegt darauf, dass Linux-Administratoren ihre praktischen Linux-Kenntnisse unter Beweis stellen, anstatt sich ausschließlich auf das Bestehen von Prüfungen oder das Auswendiglernen zu konzentrieren.

Generell gilt: Neben einer intensiven Auseinandersetzung mit dem Prüfungsstoff während der Schulung sind selbst erworbene Erfahrungen und die praktische Anwendung von Linux entscheidende Erfolgsfaktoren für die LPIC-Zertifizierung.

Das Ziel der Komplettausbildung ist es, den Teilnehmern die erforderlichen Kenntnisse für die LPIC-3-Zertifizierung zu vermitteln. Dies beinhaltet die praxisnahe Vermittlung relevanter Themen für die täglichen Aufgaben eines Administrations- oder Service-Arbeitsplatzes sowie die gezielte Vorbereitung auf die Zertifizierungsprüfungen des Linux Professional Institute. Darüber hinaus werden Softskills im Bereich Problembehandlung, Planung und Änderung von IT-Umgebungen entwickelt.

Es ist zu beachten, dass die Prüfungsgebühren nicht im Kurspreis enthalten sind. Das LPIC-3 Level bietet verschiedene Spezialisierungen, darunter Mixed Environment, Security, Virtualisierung und Hochverfügbarkeit, sowie Virtualization and Containerization. Der Kurs konzentriert sich insbesondere auf das Spezialisierungsgebiet 304: Virtualisierung und Hochverfügbarkeit.
