A Cortex XDR agent is installed on an endpoint, but the agent is unable to download content updates and has not registered with the Cortex XSIAM…

The cytool command-line utility is used for local administration of the Cortex XDR agent on an endpoint. To configure the agent to use a proxy server, the config proxy command is used. Option B provides the correct syntax, where cytool config proxy is the command group, followed by the --host and --port flags to specify the FQDN and listening port of the Broker VM acting as a proxy. This structure correctly applies the necessary network configuration for the agent to communicate through the designated proxy.

A. cytool proxy set "crtxbroker01. company.net: 8888" This command is incorrect. The primary module for configuration is config, not proxy. The correct command structure begins with cytool config proxy.
C. cytool set proxy --host crtxbroker01.company.net --port 8888 This command is invalid. set is not a primary command module in cytool; configuration changes are managed under the config module.
D. cytool proxy config "crtxbroker01.company.net:8888" This command uses an incorrect order for the modules. The correct syntax is config proxy, which specifies the configuration (config) of the proxy feature (proxy).

Reference: In the section "Use Cytool to Manage the Cortex XDR Agent," the documentation outlines the commands for agent administration. Under "Proxy Communication" or "Configuration Commands," it specifies that proxy settings are managed using the cytool config proxy command group. This confirms that config is the primary module and proxy is the sub-module, validating the structure in option B and invalidating the structures in A, C, and D. The guide shows the command cytool config proxy set , confirming config proxy as the correct prefix.
