VCP-VMC 2024 Question 43
Select 4A company is deploying a multi-tier application in a VMware Cloud environment and requires high availability and resilience. Which of the following configurations would ensure minimal downtime in case of a host failure and provide application-level resilience?
- A
Configure VMware vSphere High Availability (HA) for the cluster to restart virtual machines in case of a host failure.
- B
Deploy the application across multiple Availability Zones using VMware Cloud on AWS.
- C
Use VMware vSphere Fault Tolerance (FT) to protect the virtual machines hosting critical application components.
- D
Configure vSphere Distributed Resource Scheduler (DRS) to automatically balance workloads across hosts within the cluster.
- E
Enable vSAN stretched cluster to replicate data between different geographic locations in real-time.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Achieving high availability and resilience in a VMware Cloud environment requires using multiple techniques to mitigate different types of failures. vSphere HA protects against host failures, vSphere FT protects critical application-level components, and vSAN stretched cluster ensures data resilience. Deploying across multiple Availability Zones further enhances resilience to site-wide failures. DRS, while useful for resource optimization, does not directly contribute to HA or resilience.
- A. Correct.
vSphere HA ensures virtual machines are restarted on another host in the event of a host failure, providing host-level resilience. However, it does not protect against application-level failures.
- B. Correct.
Deploying the application across multiple Availability Zones ensures resilience to catastrophic failures impacting an entire site or zone, improving overall availability.
- C. Correct.
vSphere FT provides continuous availability for critical virtual machines by creating a live shadow instance that takes over in case of a primary VM failure.
- D. Incorrect.
DRS is designed for resource optimization and load balancing, but it does not provide high availability or resilience directly.
- E. Correct.
vSAN stretched cluster provides real-time data replication across geographic locations, ensuring data availability and resilience even if one location is unavailable.
