What feature allows support staff to troubleshoot devices remotely in Intune?

The feature that enables support staff to troubleshoot devices remotely in Intune is the use of remote assistance tools. These tools provide technicians with the capability to connect to a user's device, allowing them to diagnose and resolve issues directly from their own workstation. The remote assistance tools are vital in providing real-time support, as they can help users through complex tasks, assist in configuring settings, and quickly address troubleshooting needs without needing physical access to the device.

The other options, while related to device management and monitoring, do not serve the primary function of on-the-spot remote troubleshooting. Device compliance policies are focused on ensuring devices meet certain security and health criteria, while application performance analytics track how applications function across devices, providing insights but not direct support capabilities. Activity logs are instrumental in auditing actions taken on devices but do not facilitate real-time interactive troubleshooting sessions necessary for effective support.
