Your network contains a three-node Exchange Server 3003 active/passive cluster.
The nodes are named Exchange1, Exchange2, and Exchange3.
The cluster hosts two Exchange Virtual Servers (EVS) named EVS1 and EVS2.
You need to ensure that Exchange1 only hosts an EVS if either Exchange2 or Exchange3 fails.
What should you do?

A.
On both EVS1 and EVS2, configure a failover threshold of two.

B.
On both EVS1 and EVS2, configure the setting to prevent failback.

C.
Configure Exchange2 as the preferred owner for EVS1. Configure Exchange3 as the preferred owner for EVS2.

D.
Configure Exchange2 and Exchange3 as possible owners of the clustered Exchange System Attendant resource
