問題文

A dial peer on a border element is tied to one interface and points at a server group that belongs to a routing instance of its own. What does the guide have the operator line up for that pair?

選択肢

1. The patterns of the group with the ones that the same interface matches, since a pattern outside that reach leaves the leg with a stray call on its hands.
2. The targets of the group with the network that the same far end reaches, since a target outside that reach leaves the leg with a route of its own to follow.
3. The targets of the group with the network that the bound interface reaches, since a target outside that reach leaves the leg with nowhere to send its requests.
4. The codecs of the group with the ones that the same interface carries, since a codec outside that reach leaves the leg with a silent path to the far end.
