Huawei USG firewalls offer flexible management options to meet diverse operational needs. Below is an analysis of each option:
* SecoManager : USG firewalls can be managed centrally through SecoManager, which provides unified security policy orchestration and monitoring.
* Commands : Administrators can use CLI (Command-Line Interface) commands to configure and manage the firewall directly.
* CloudWAN : This is not a management mode for USG firewalls. CloudWAN is a solution for wide- area network management and is unrelated to firewall O&M.
* Web NMS : USG firewalls support web-based Network Management Systems (NMS) for graphical configuration and monitoring.
Thus, the correct answers are A , B , and D .
