Please guide as to which is the best option for this question. I lean towards (III) as explained below but on another group I belong, some people also belive strongly that (IV) should be the answer

Which action is performed by Link Management Protocol in a Cisco StackWise Virtual domain?
[*]I. It determines which switch becomes active or standby.
[*]II. It determines if the hardware is compatible to form the StackWise Virtual domain.
[*]III. It rejects any unidirectional link traffic forwarding
[*]IV. It discovers the StackWise domain and brings up SVL interfaces.

Link Management Protocol (LMP) performs the following functions:
• Verifies link integrity by establishing bidirectional traffic forwarding, and rejects any unidirectional links
• Exchanges periodic hellos to monitor and maintain the health of the links
• Negotiates the version of StackWise Virtual header between the switchesThe Link Management Protocol (LMP) is activated on each link of the StackWise Virtual link as soon as it is brought up online.

IV. It discovers the StackWise domain and brings up SVL interfaces.

解释：
这是 Link Management Protocol (LMP) 最根本的职责。它负责在两条物理交换机之间的链路上运行，发现对端的堆叠伙伴，协商参数，并最终建立起作为堆叠虚拟链路（SVL）的逻辑接口。没有这个初始的发现和建立过程，StackWise Virtual 域就无法形成。
