Which CLI command would an administrator use to allow syslog on an ESXi transport node when using the esxcli utility?

The correct command for allowing syslog on an ESXi transport node using the esxcli utility is designed to specifically enable the syslog ruleset in the network firewall. By using the command that sets the syslog ruleset to enabled, the administrator is ensuring that syslog traffic can flow through the firewall, which is essential for logging purposes.

This command structure effectively tells the ESXi host to enable the ruleset associated with syslog, thus permitting the necessary traffic for logging operations to be processed. When this configuration is applied, it allows for effective monitoring, troubleshooting, and auditing of the environment, as syslog messages can be sent to a remote logging server or centralized log management system.

The other options do not achieve the same result: some options either disable syslog (where "false" is set) or lack the necessary parameters to function effectively. Thus, enabling syslog with the correct command is crucial for maintaining effective logging mechanisms in an ESXi transport node.
