2V0-622 Question #182: Real Exam Question with Answer & Explanation
The correct answer is A: A local device is mounted to one or more virtual machines.. A DRS-enabled cluster may show imbalance when VMs cannot be migrated due to local device attachments, DRS rule constraints, or vMotion being unconfigured.
Section 5 – Administer and Protect vSphere 6.5 Resources
Question
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 causes of the cluster imbalance? (Choose three.)
Exhibit
Options
- AA local device is mounted to one or more virtual machines.
- BDRS rules prevent virtual machines from being moved.
- CvMotion is not configured and enabled.
- DThere are insufficient cluster resources to perform the migration.
- EDRS has been configured for a conservative migration threshold.
Explanation
A DRS-enabled cluster may show imbalance when VMs cannot be migrated due to local device attachments, DRS rule constraints, or vMotion being unconfigured.
Common mistakes.
- D. 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.
- E. 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.
