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

Seminarinformationen

Seminar - Ziel

In dieser 5-tägigen Schulung "Linux-LPI - LPIC-3 (305: Virtualization und Containerization)" bereiten wir Sie intensiv auf die LPIC-3-Zertifizierungsprüfung 305 Virtualisierung und Containerisierung vor. Das Hauptziel dieser Schulung ist es, Ihre fortgeschrittenen Linux-Kenntnisse im Bereich der Virtualisierung und Containerisierung zu demonstrieren, und nicht nur das Bestehen von Prüfungen zu betonen.

Unsere Schulung vermittelt nicht nur den Prüfungsstoff, sondern legt auch großen Wert auf Ihre eigene Erfahrung und Praxis im Umgang mit Linux. Die Komplettausbildung konzentriert sich darauf, Ihnen die erforderlichen Kenntnisse zur LPIC-3-Zertifizierung zu vermitteln. Dies beinhaltet praxisrelevante Themen, um Sie für Aufgaben in der Administration oder im Service im Bereich Virtualisierung und Containerisierung zu befähigen.

Wir bereiten Sie gezielt auf die Zertifizierungsprüfungen des Linux Professional Institute vor und fördern Ihre Softskills im Bereich Problembehandlung, Planung und Änderung von IT-Umgebungen. Bitte beachten Sie, dass die Prüfungsgebühren nicht im Kurspreis enthalten sind.

Unser Schulungsangebot umfasst verschiedene Spezialisierungen des LPIC-3-Levels, darunter Linux LPI - LPIC-3 (300: Mixed Environment), Linux-LPI - LPIC-3 (303: Security), 304: Virtualisierung und Hochverfügbarkeit, 305: Virtualisierung und Containerisierung sowie Linux-LPI - LPIC-3 (306: High Availability Systems and Storage).
