VCP-VMC 2024 Question 42
Select 3A company is running a mission-critical application on a VMware Cloud environment. The application requires minimal downtime and data loss in case of a host failure. As part of the design, the company wants to ensure high availability and resiliency. Which configurations should be implemented to meet these requirements?
- A
Enable vSphere HA on the cluster and configure Admission Control.
- B
Configure vSAN with RAID-5/6 for storage redundancy.
- C
Use vMotion to migrate VMs manually in case of a host failure.
- D
Deploy the application in a stretched cluster configuration.
- E
Disable DRS to avoid unnecessary VM migrations.
Show answer and explanation
Correct answers: A, B, D
Explanation
To achieve a highly available and resilient infrastructure, features like vSphere HA and vSAN are crucial as they ensure automated failover and data redundancy. A stretched cluster adds an additional layer of resiliency by protecting against site-level failures. While vMotion and DRS are useful features, they must be used in specific scenarios, and disabling DRS would contradict the goal of high availability.
- A. Correct.
Enabling vSphere HA ensures that virtual machines are automatically restarted on a healthy host in case of a host failure. Admission Control enforces resource availability for failover scenarios, making this an essential configuration for high availability.
- B. Correct.
vSAN with RAID-5/6 provides storage redundancy, ensuring data is protected and available even if one or more disks fail, which is critical for resiliency.
- C. Incorrect.
vMotion is a tool for live migration of VMs but does not automatically react to a host failure. It requires manual intervention, which does not align with requirements for minimal downtime.
- D. Correct.
A stretched cluster configuration provides geographical redundancy and resiliency. It allows VMs to failover between sites, ensuring high availability in case of a site-level failure.
- E. Incorrect.
Disabling DRS is not recommended as it reduces the cluster's ability to balance workloads and respond to host failures effectively, which negatively impacts availability.
