Which condition will cause a HA/DRS cluster to display a yellow health indicator?
A. There are insufficient resources to satisfy the cluster’s requirements.
B. A virtual machine has failed and cannot be restarted in the cluster.
C. Virtual machine I/O activity in the cluster has reached or exceeded a critical level.
D. One or more hosts in the cluster has entered maintenance mode.
Correct Answer: A
Explanation/Reference:
Explanation:
A: When monitoring DRS behavior, the Hardware status tab will monitor the host health and this is displayed in different colors. If a component is functioning normally, the status indicator is green. The status indicator changes to yellow or red if a system component violates a performance threshold or is not functioning properly. Generally, a yellow indicator signifies degraded performance. A red indicator signifies that a component stopped operating or exceeded the highest threshold. If the status is blank, then the health monitoring service cannot determine the status of the component. Thus the cluster health monitor shows insufficient resources.
Incorrect Answers:
B: The health indicator will be red in this case.
C: The health indicator will display a red color.
D: The health indictor will indicate a blank because it will not be able to determine the status of the components in maintenance mode.
