If the questions are duplicates, one should be closed as such. In that case, it should be explained to the user that we prefer information to be centralized, so they should flag instead of posting the same answer to both. Once the duplicate question relationship is established, one of the duplicate answers can be deleted. Those two questions look pretty similar to me (same hardware), but it looks like they're trying to do slightly different things, so I don't have strong feelings either way.
Each answer must address the question. Ones that don't should be flagged as NAA, and ones that do so poorly should be downvoted. Usually, a copied answer needs to be tailored to make sense as a direct response to its question. If each duplicate answer makes sense in its context, then they're fine. In this case, the answer does seem like it might be helpful to both questions, so I'm not too worried about these.
Identical answers already cause an automatic moderator flag to be raised. If there is a specific moderator action you think should be taken, you can raise a custom flag.
