The tool that the security administrator is using to remediate a security vulnerability that may affect the sensors is Live Response. Live Response is a feature of VMware Carbon Black Cloud Endpoint Standard that allows the administrator to perform remote investigations, contain ongoing attacks, and remediate threats using a command line interface. Live Response enables the administrator to interact with the sensors and access the endpoints in real time, using various commands and scripts. Live Response can also be used to upload or download files, execute processes, terminate processes, delete files, and more12.

The other tools are not relevant or applicable for this scenario. CBLauncher is a tool that allows the administrator to launch applications on the endpoint without triggering policy rules or alerts. CBLauncher is useful for troubleshooting application compatibility issues or testing new applications, but it does not provide interaction or remote access for further investigation3. PowerCLI is a tool that allows the administrator to automate and manage VMware products and services using PowerShell commands and scripts. PowerCLI is useful for administering VMware virtual machines, hosts, networks, storage, and more, but it does not provide interaction or remote access for further investigation4. IRepCLI is a tool that allows the administrator to generate and upload reputation information for files on the endpoint. IRepCLI is useful for enhancing the threat intelligence and detection capabilities of VMware Carbon Black Cloud, but it does not provide interaction or remote access for further investigation5. References:
