A coordinator splits a contact covering a damaged item and a duplicate charge across two subagents, briefing each one to resolve the customer's problem and passing both of them the full contact transcript. Reviewers find that both subagents investigated the duplicate charge, and in 27 of 200 such contacts the two returned different recommended amounts, with the coordinator relaying whichever result arrived last. Which TWO changes most effectively address this? Select TWO.
- AGive each subagent a brief naming the one issue it owns and the records it may read, so that the two scopes do not overlap at all. Correct
- BLet the two subagents exchange messages during the contact so they can agree between themselves which of them takes the duplicate charge.
- CHave the coordinator reconcile the returned recommendations against the order record and decide the single amount that goes to the customer itself. Correct
- DDispatch one subagent, then dispatch the second with the first one's returned transcript appended so that it can see what has already been covered.
- EInstruct both subagents to state at the top of their returned answer which of the customer's issues they chose to work on during the dispatch.
Why A is correct: Correct. Both subagents chose the same issue because nothing in either brief assigned one, and a named scope per spoke is what makes a fan-out a partition rather than a duplication.
Why B is wrong: Tempting because negotiation would settle the overlap, but spoke-to-spoke traffic breaks the hub-and-spoke property that keeps each context isolated and moves the decision away from the component accountable for it.
Why C is correct: Correct. Arrival order is not evidence, so the hub needs an explicit merge step that weighs each result against the authoritative record before anything reaches the customer.
Why D is wrong: Tempting because it does inform the second subagent, but it doubles contact latency and still leaves the scope undefined, so the second one may reinvestigate the charge it was shown.
Why E is wrong: Tempting because it makes the overlap visible in review, but reporting a choice after the fact neither prevents the duplicated work nor tells the coordinator which of two amounts to trust.
