A company has configured two switches as an HP Intelligent Resilient Framework (IRF) virtual device. The IRF
port on each switch is bound to multiple physical links. How does the switch select the link for transmitting
packets on that IRF port?

A.
It uses a round-robin mechanism in which it sends each packet over a different link in turn.

B.
It uses a weighted round-robin mechanism, in which it sends each packet over a different link in turn, but
can send more packets over certain links over higher weighted.

C.
It uses one of the links as an active link, the other links are in standby mode and can become active if the
active link fails

D.
It uses a hash of various Layer 2, 3, or 4 information in the packet, depending on the type of traffic, the
switch model, and the IRF load-sharing.

Explanation:
IRF provides both link and node redundancy.
