# Recommended VDI policies and configuration files for NPVDIs

VDI policy and VDI configuration file records to activate on your instance so that DEX can monitor non-persistent \(NP\) Virtual Desktop Infrastructures \(VDIs\).

Configure these records as described in [Prepare agent deployment on a non-persistent virtual desktop infrastructure machine](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/agent-client-collector/npvdi-agent-instance-prep.md).
