Are you preparing for a VMware interview? Here’s a comprehensive list of essential questions covering troubleshooting, upgrades, networking, storage, and more to help you crack your next interview.
You Should Know:
Troubleshooting & Performance Commands:
Restart management services on ESXi /etc/init.d/hostd restart /etc/init.d/vpxa restart Check VM performance metrics esxtop
PowerShell command to check VM performance Get-Stat -Entity (Get-VM) -Realtime -MaxSamples 1 | Select Entity, MetricId, Value
Infrastructure & Upgrade Commands:
List all datastores esxcli storage filesystem list Check current ESXi version vmware -vl Put host into maintenance mode esxcli system maintenanceMode set --enable true
Networking & Storage Commands:
List network adapters esxcli network nic list Check storage paths esxcli storage core path list Migrate VM storage (CLI alternative) vim-cmd vmsvc/getallvms | grep -i "vmname" vim-cmd vmsvc/reload <vmid>
High Availability Commands:
Check HA status esxcli cluster ha status get List DPM settings esxcli system wka get
VSAN Specific Commands:
Check VSAN cluster status esxcli vsan cluster get Replace VSAN disk esxcli vsan storage remove -s <ssd-uuid> esxcli vsan storage add -s <new-ssd-uuid> -d <new-disk-uuid>
What Undercode Say:
VMware administration requires deep knowledge of both GUI and CLI tools. Mastering these commands will give you an edge in troubleshooting and daily operations. Key areas to focus on include:
1. Performance monitoring with esxtop and resxtop
2. Log analysis in /var/log/ directory
3. Network troubleshooting with esxcli network commands
4. Storage management using vmkfstools
5. Automation with PowerCLI for large environments
Remember these essential Linux commands for VMware administration:
Check memory usage free -h Check disk space df -h Monitor processes top Search logs grep -i "error" /var/log/vmware/hostd.log Check network connectivity vmkping <ip-address>
For Windows administrators working with VMware, these PowerShell commands are valuable:
Connect to vCenter Connect-VIServer -Server <vcenter-address> Get all VMs with snapshots Get-VM | Get-Snapshot | Select VM, Name, Created Export VM list Get-VM | Export-Csv -Path "C:\vm_inventory.csv"
Expected Output:
A comprehensive VMware knowledge base covering interview questions, practical commands, and troubleshooting techniques for both Linux and Windows environments.
