2V0-21.23 Question 192
Select 2An administrator is configuring a vSphere cluster with VMware High Availability (HA) and Distributed Resource Scheduler (DRS). The requirement is to ensure that during a host failure, virtual machines are restarted on other hosts in the cluster while maintaining sufficient resources for potential failures. Additionally, the cluster should take proactive measures by migrating virtual machines away from a host showing potential hardware failures. Which combination of configurations would meet these requirements?
- A
Enable Admission Control and configure the 'Host Failures Cluster Tolerates' policy.
- B
Enable Proactive HA and configure a Proactive HA Automation Level to 'Manual'.
- C
Enable Proactive HA and configure a Proactive HA Automation Level to 'Automated'.
- D
Set the DRS Automation Level to 'Partially Automated'.
- E
Disable Admission Control to allow maximum flexibility for resource utilization.
Show answer and explanation
Correct answers: A, C
Explanation
To meet the requirements, enabling Admission Control with the 'Host Failures Cluster Tolerates' policy ensures there are enough reserved resources in the cluster for failover scenarios, while enabling Proactive HA with 'Automated' automation level ensures that virtual machines are automatically migrated off hosts showing potential hardware issues. These configurations collectively provide both reactive and proactive measures for the cluster.
- A. Correct.
Admission Control ensures that sufficient resources are reserved in the cluster to restart virtual machines in the event of a host failure. Configuring the 'Host Failures Cluster Tolerates' policy is appropriate to meet the requirement of maintaining resources for potential failures.
- B. Incorrect.
Proactive HA with 'Manual' automation level will require administrative intervention to migrate virtual machines when a host shows potential hardware failures. This does not meet the requirement for automatic proactive measures.
- C. Correct.
Proactive HA with 'Automated' automation level automatically migrates virtual machines away from hosts with potential hardware failures, meeting the requirement for proactive measures.
- D. Incorrect.
Setting DRS Automation Level to 'Partially Automated' only automates initial placements but does not handle migrations effectively under normal or proactive conditions, hence it does not fully meet the requirements.
- E. Incorrect.
Disabling Admission Control would allow resource overcommitment, which contradicts the requirement to maintain sufficient resources for potential failures.
