This five-day training course provides you with the knowledge, skills, and abilities to achieve competence in troubleshooting the VMware vSphere® 8 environment. This course increases your skill level and competence in using the command-line interface, VMware vSphere® Client™, log files, and other tools to analyze and solve problems.

Audience

System architects and system administrators

Prerequisites

This course requires completion of one the following courses:

• VCP-DCV certification
• VMware vSphere: Install, Configure, Manage
• VMware vSphere: Operate, Scale and Secure

The course material presumes that you can perform the following tasks with no assistance or guidance before enrolling in this course:

• Install and configure ESXi
• Install vCenter Server
• Create vCenter Server objects, such as data centers and folders
• Create and modify a standard switch
• Create and modify a distributed switch
• Connect an ESXi host to NAS, iSCSI, or Fibre Channel storage
• Create a VMware vSphere VMFS datastore
