Refer to the Exhibit. An administrator is reviewing a vSphere Distributed Resource Scheduler (DRS) enabled Cluster and observes unexpected behavior as shown in the Exhibit. What are three potential ca

A local device (such as a USB device or local CD-ROM ISO) mounted to a VM prevents vMotion from migrating that VM, causing it to remain pinned to its host and contributing to imbalance.

DRS affinity or anti-affinity rules can explicitly prevent VMs from being moved to other hosts, leaving DRS unable to rebalance even when resources are uneven.

DRS relies entirely on vMotion to execute live migrations; if vMotion is not configured or enabled on the hosts, DRS cannot move any VMs regardless of cluster imbalance.

Insufficient cluster resources would prevent migrations but would typically surface as a capacity alert rather than a DRS imbalance, and DRS would still attempt to rebalance by making recommendations.

A conservative migration threshold reduces the number of DRS recommendations and migrations but does not directly cause a cluster imbalance - it only affects how aggressively DRS acts on imbalances.
