Explanation:
You should place the file share witness in the Chicago site. Placing the file share witness in Chicago would give both New York and Los Angeles an opportunity to maintain quorum in the event that the other were to become unavailable. You should place the cluster core resource group in the New York site. Placing the cluster core resource group in New York would give that site an advantage toward maintaining quorum if the network link between New York and Chicago were to go down due to the arbitration delay. All members of the cluster except for the member owning the cluster core resource group must wait for a period of time equal to the arbitration delay before attempting to lock the file share witness (six seconds by default). The site with the member that locks the file share witness will maintain quorum.
You should not place the file share witness in the New York site. A loss of the New York site would result in the cluster losing quorum across both sites and all databases dismounting.
You should not add an additional Exchange server to DAG1 and place it in the New York site. Adding an additional Exchange server to the DAG in New York is incorrect because the DAG is already at its maximum capacity of sixteen nodes.
You should not add an additional Exchange server to DAG1 and place it in the Chicago site. Adding an additional Exchange server to the DAG in Chicago is incorrect because the DAG is already at its maximum capacity of sixteen nodes.
You should not place the cluster core resource group in the Chicago site. The cluster core resource group cannot be placed in Chicago because there are no cluster members there, and you must place the file share witness there. The cluster core resource group cannot be owned by the file share witness server.
