1. Plan strategies to monitor and troubleshoot the performance of enterprise virtual computing environment
   • . Develop a plan to monitor virtual environment to ensure availability and optimal performance according to enterprise requirements
   • . Identify virtual environment critical activity level and assign resources as needed
   • . Review system logs and alerts to facilitate virtual environment tuning
2. Manage virtual environment performance to ensure full resource optimisation
   • . Monitor and diagnose memory, central processing unit (CPU) and distributed power management performance
   • . Review storage and cluster performance to maximise operational efficiency
   • . Monitor tasks, events and alarms, and network activity and make relevant adjustments to ensure optimal operation
3. Analyse and troubleshoot virtual environments
   • . Review virtual machine capacity, application and storage input and output (I/O) performance to identify and resolve performance issues
   • . Test, analyse and troubleshoot identified virtual network problems
   • . Analyse and troubleshoot high availability to ensure that virtual machines are running at optimal performance levels
   • . Consult with virtualisation software vendors in order to provide solutions
4. Diagnose virtual environment faults and provide solutions
   • . Use virtualisation client and server management software tools to help diagnose virtual environment problems
   • . Install and configure external virtualisation management tools to help diagnose virtual environment problems
   • . Use system logs and alerts to collect and analyse errors
   • . Evaluate problems using log files and alerts

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
