In the HPE GreenLake model, how is the "buffer" capacity typically handled?
Show answer details
Correct answer: A
HPE GreenLake provisions additional "buffer" capacity on-premises ahead of demand. The customer is only billed for this capacity once it is actively consumed, ensuring resources are instantly available without upfront CAPEX.
- 2
Which storage architecture provides block-level access to data over a dedicated high-speed network, typically using Fibre Channel or iSCSI protocols?
Show answer details
Correct answer: C
A Storage Area Network (SAN) is a dedicated high-speed network that provides block-level access to storage. NAS provides file-level access over standard Ethernet, while DAS is directly connected to a single host without a network.
- 3
A customer is developing a cloud-native application that needs to store billions of images and videos. They require a flat namespace, rich metadata tagging, and access via RESTful APIs. Which storage implementation is best suited for this requirement?
Show answer details
Correct answer: C
Object storage uses a flat namespace (no directories), supports custom rich metadata, and is accessed via REST APIs (like Amazon S3), making it ideal for massive unstructured data repositories.
- 4
A customer wants to transition their on-premises storage to a pay-per-use model to align expenses with actual usage. Which HPE offering provides this consumption-based model for on-premises infrastructure?
Show answer details
Correct answer: B
HPE GreenLake is HPE's portfolio of cloud and as-a-service solutions, delivering cloud-like experiences and a pay-per-use financial model for on-premises, edge, and colocation infrastructure.

A financial enterprise is planning a technology refresh for their core banking application and unstructured data archives.
The current environment suffers from unpredictable performance spikes, leading to application timeouts during end-of-month processing. They have a strict requirement for 100% data availability for the core banking database.
For their unstructured data, they need a scalable repository that can grow to several petabytes over the next three years, primarily accessed via S3-compatible APIs.
The CIO wants to shift from a CAPEX model to an OPEX model, paying only for the storage they consume while keeping all data within their own data center due to regulatory compliance.
