Exhibit:

Refer to the exhibit. You have six IP phones making six conference calls. Which conference
resource will Conference 4 use?

A.
HW_CFB_1

SW_CFB_2

Explanation:
There’s no way SW_CFB_2 be the media resource used for the 4th conference,
because SW_CFB_1 is the first option in MRG_SW_CFB after the 3 first conferences using the
three resources in MRG_HW_CFB.
