VCP-VMC 2024 Question 44
Select 3An organization is designing their VMware Cloud infrastructure to ensure high availability and resilience for mission-critical workloads. They want to prevent a single point of failure and ensure workloads are automatically restarted in case of a host failure. Which combination of features would best meet these requirements?
- A
vSphere High Availability (HA)
- B
vSAN Stretched Cluster
- C
VMware Fault Tolerance (FT)
- D
Distributed Resource Scheduler (DRS)
- E
vSphere Replication
Show answer and explanation
Correct answers: A, B, D
Explanation
The combination of vSphere High Availability (HA), vSAN Stretched Cluster, and Distributed Resource Scheduler (DRS) provides a robust foundation for high availability and resilience in a VMware Cloud infrastructure. HA ensures workloads are restarted on healthy hosts in case of a failure, the vSAN Stretched Cluster replicates data across failure domains for resilience, and DRS optimizes workload distribution to prevent resource contention. Together, these features address both host and data availability while maintaining performance and reliability for mission-critical workloads.
- A. Correct.
vSphere High Availability (HA) is a key feature designed to automatically restart virtual machines on a different host in case of a host failure, ensuring high availability for workloads.
- B. Correct.
vSAN Stretched Cluster provides resilience by replicating data across multiple locations or failure domains. This ensures that even in the event of a site or host failure, data remains accessible.
- C. Incorrect.
VMware Fault Tolerance (FT) provides continuous availability for a single VM by creating a live secondary VM, but it is resource-intensive and not scalable for large environments. It is not the best option for high availability and resilience at scale.
- D. Correct.
Distributed Resource Scheduler (DRS) complements HA by automatically balancing workloads across hosts in the cluster to ensure optimal performance and minimize the risk of resource contention. While it doesn't directly handle failures, it enhances overall resilience by maintaining cluster health.
- E. Incorrect.
vSphere Replication focuses on data replication for disaster recovery scenarios but does not provide automatic failover or restart capabilities, making it less suitable for achieving high availability in real-time scenarios.
