問題文
A chain has just added the pairing of a name and a number for one of its sections under the profile that its shops use for folding traffic back on the spot, because the number behind that name differs from shop to shop. The networks that name that section are up and carrying clients. What does the guide ask of the chain for the new pairing to reach the units?
選択肢
- The policy profiles that name that section have to be taken down and put back up, because a client is otherwise handed an address out of a section other than the one that the chain meant.
- The pairing reaches the units on the round of settings that follows, because a profile of that kind is carried down to a unit whenever any line inside it has been written afresh.
- The units that hold that section have to be taken out of the profile and put back into it, because the pairing of a name and a number is held by a unit rather than by the profile above it.
- The name has to be written a second time on each of the units by hand, because the guide holds the pairing under a profile to stand for the box alone and not for a unit at a shop.
