An environment is running a cluster with six i3.metal hosts in the VMware Cloud on AWS software-defined data center (SDDC). If one host fails, what happens after a new host is automatically added to the cluster?

A. The SDDC and NVMe drives backing VMware vSAN capacity are unmounted from the failed host and attached to the new host. There is no VMware vSAN rebuild required.

B. The VMware vSAN rebuild starts in the background. Performance might be degraded during rebuild and the failures to tolerate (FTT) is lowered to 0.

C. The VMware vSAN rebuild starts in the background. Performance might be degraded during rebuild and the failures to tolerate (FTT) is lowered to 1.

D. A notification is received from VMware Support to start the VMware vSAN rebuild. Performance might be degraded during rebuild.
