* Understanding the Concept: The "Buffer" in HPE GreenLake refers to additional capacity provided within the as-a-service model. * Buffer Options: A . Capacity for Management and Logs: While necessary, this is not specifically referred to as the "Buffer." B . Reserved Capacity for Failure: Critical but not the primary purpose of the "Buffer" in the GreenLake context. C . Capacity Available for Consumption: This aligns with the "Buffer" concept in GreenLake, where extra capacity is pre-installed and can be used as demand increases. D . Reserved for Upgrades and Updates: Not specifically referred to as the "Buffer." * Why C is the Correct answer: On-Demand Availability: The buffer capacity is pre-installed and immediately available, allowing customers to scale quickly without waiting for additional infrastructure to be provisioned. Flexibility: It ensures that there is always enough capacity to handle unexpected increases in demand. * Reference: HPE GreenLake Overview: HPE GreenLake Understanding HPE GreenLake Buffer Capacity: HPE GreenLake Buffer
