AAXSTS - Aruba Advanced OS-CX Switching
& Troubleshooting Solutions Version 2023

Description

Ce cours est structuré pour aider l'étudiant à acquérir ce niveau d'expertise le plus élevé, avec les solutions de commutation filaire d'Aruba, y compris la capacité de mettre en œuvre et d'optimiser les solutions de LAN de campus Aruba Switching au niveau de l'entreprise. Le cours se concentre sur l'interprétation des architectures de réseau complexes et des exigences des clients pour mettre en œuvre, surveiller, dépanner et optimiser les solutions de réseau multi-fournisseurs. L'étudiant est encouragé à utiliser son esprit critique pour résoudre des problèmes complexes dans l'environnement qui dépassent l'expertise de l'intégrateur de niveau professionnel. Pendant l'exécution de ses tâches principales, l'étudiant est également encouragé à faire preuve du plus haut niveau de réflexion stratégique et de résolution de problèmes. Cela comprendra la définition de plans opérationnels pour les résultats souhaités afin de satisfaire les besoins immédiats ainsi que les possibilités de croissance futures prévues. Ce cours comprend environ 35 % de cours magistraux et 65 % d'exercices pratiques en laboratoire basés sur des scénarios. À l'issue de ce cours, les étudiants sont préparés aux examens écrits et pratiques de l'Aruba Certified Switching Expert (ACSX).
