Which statement is accurate regarding the CLI?

The statement regarding the CLI enabling tasks like creating bridge domains and groups is accurate because the Command-Line Interface (CLI) is a powerful tool used for configuration and management of network devices, including those managed by the Application Policy Infrastructure Controller (APIC) in a Cisco environment. With the CLI, network administrators can execute a wide variety of commands to configure network services, including the creation and management of bridge domains and endpoint groups, which are essential components in Software-Defined Networking (SDN) architectures. The CLI provides direct access to these functionalities, allowing for precise control and automation of tasks within the network infrastructure.

Other options imply limitations or inaccuracies regarding command execution. The CLI operates independently of the interfaces mentioned, allowing commands to be run directly on the device or via SSH/Telnet terminals, not just restricted to XML or JSON interfaces. Additionally, while the APIC GUI does provide documentation for many commands, the statement about all commands being documented there is misleading, as documentation can often be found in multiple places, including command reference guides and online resources. Therefore, the focus on the CLI's capability to enable essential network configurations makes the first statement accurate and relevant.
