Fundamental virtualization and vSphere concepts: how physical compute, storage, and networking resources are abstracted and delivered to virtual machines; hypervisor types; core vSphere components and their roles (ESXi, vCenter, VM constructs); and basic storage and networking technologies used in VMware environments.
Overview of VMware product portfolio and how solutions map to business needs: key products and features (vSphere/ESXi, vCenter, vSAN, NSX, VMware Cloud Foundation and related management tooling) and typical use cases for each within data center virtualization.
Principles and practices for designing vSphere-based solutions: capacity and resource planning, host/cluster sizing, storage and network design considerations, HA/DR/availability planning, and mapping business requirements to vSphere design choices.
Tasks and best practices for deploying and configuring vSphere components: ESXi host installation, vCenter Server deployment, datastore and virtual network configuration, initial VM provisioning and inventory setup, and configuring fundamental cluster features (HA, DRS, EVC where applicable).
Monitoring and optimizing vSphere performance and lifecycle: interpreting performance metrics and alarms, tuning CPU/memory/storage/network resources, capacity optimization techniques, and safe procedures for patching and upgrading vSphere components.

Monitoring and optimizing vSphere performance and lifecycle: interpreting performance metrics and alarms, tuning CPU/memory/storage/network resources, capacity optimization techniques, and safe procedures for patching and upgrading vSphere components.
un domaine 6
Troubleshooting and Repairing
Techniques for diagnosing and resolving common vSphere issues: using logs, events and native tools to troubleshoot compute, storage and network problems; common failure scenarios (vMotion, storage access, host/VM faults); and escalation/repair workflows.
un domaine 7
Administrative and Operational Tasks
Day-to-day operational responsibilities: user and role-based access control, backup and recovery considerations, managing snapshots/templates and VM lifecycle, monitoring and alerting, inventory and configuration management, and routine administrative tasks.
Conseil d'étude
Use VMware's exam guide, study vSphere fundamentals, build hands-on home or eval labs, and complete timed practice exams and flashcards.
