問題文
Audio runs in one direction only on a trunk whose bound interface was shut administratively while calls were up on it. Which account of that fits?
選択肢
- Media carried on towards the outgoing gateway alone, since the address that had the interface bound is held by the side that terminates the call and not the other.
- Media moved onto the next interface named in the tenant, since a binding drops one level down the order of preference the moment its own interface goes away.
- Media carried on from the outgoing gateway towards the terminating one and no further, since the binding fell out of use for the messages that came after.
- Media halted in both of the directions the instant the interface went down, since the receivers that carry it were closed at the same moment as the interface.
