Which Cisco DNA Center feature allows running diagnostic CLI commands on managed devices?

Command Runner is the correct answer because it is a Cisco DNA Center feature specifically designed to execute CLI commands on managed network devices for diagnostic and troubleshooting purposes. It allows network administrators to run ad-hoc commands and view their output directly within the DNA Center interface. DNA Spaces is incorrect because it is a location-based services platform, not a tool for CLI command execution. DNA Advantage is incorrect as it is a licensing tier for Cisco DNA Center, not a feature for running commands. Intelligent Capture is incorrect because it is a feature for capturing and analyzing network packets, not for executing CLI commands.
