Differentiate and apply foundational storage architectures and technologies · Describe and characterize the different SAN topologies
An organization is redesigning its Fibre Channel SAN to support 2,000 servers and 4 enterprise storage arrays. They require high scalability, predictable performance for storage traffic, and simplified management. Which SAN topology best meets these requirements?
Show answer & explanation
Correct answer: A
A Core-edge topology connects servers to edge switches and storage to core switches. This provides high scalability, limits the number of hops (predictable performance), and simplifies management compared to deeply cascaded or full-mesh topologies at large scale.

Differentiate and apply foundational storage architectures and technologies · Describe data availability and resiliency methodologies
A customer needs to store 500 TB of unstructured archive data. They require high data durability capable of surviving multiple simultaneous drive failures, but they are extremely constrained by budget and physical rack space. Which data resiliency methodology provides the highest usable capacity relative to raw capacity while maintaining high fault tolerance?
Show answer & explanation
Correct answer: D
Erasure coding breaks data into fragments, expands them with redundant data pieces, and stores them across a set of different locations. It provides higher fault tolerance (can survive multiple failures depending on the configuration) with significantly less capacity overhead compared to mirroring (RAID 10), making it ideal for large-scale archive data where space and cost are constrained.

Differentiate and apply foundational storage architectures and technologies · Identify Storage optimization technologies
A storage architect is evaluating which workloads to place on a newly deployed storage array featuring inline deduplication and compression. Which TWO of the following workloads will typically yield the highest data reduction ratios? (Select TWO)
Show answer & explanation
Correct answers: A, C
VDI full clones contain highly identical operating system files across hundreds or thousands of instances, resulting in excellent deduplication ratios.
Server virtualization datastores typically host multiple VMs with similar OS binaries and templates, providing high deduplication and compression efficiency.
- Question 4Intermediate
Describe HPE Storage architectures and technologies · Describe and compare HPE Storage hardware/software
A large retail enterprise requires a storage solution for their core payment processing database. The primary requirement is a 100% data availability guarantee, alongside massive parallelism to handle unpredictable workload spikes during holiday seasons. Which HPE Storage platform is specifically positioned for this mission-critical requirement?
Show answer & explanation
Correct answer: D
HPE Alletra 9000 is positioned for mission-critical workloads. It features a multi-node, active-active architecture that delivers massive parallelism and comes with a standard 100% data availability guarantee, making it the ideal choice for core payment processing databases.
- Question 5Beginner
Describe HPE Storage architectures and technologies · Describe HPE Storage services
HPE GreenLake for Block Storage relies on Data Services Cloud Console (DSCC) to provide a cloud operating experience for on-premises storage, allowing for intent-based provisioning.
Show answer & explanation
Correct answer: A
True. Data Services Cloud Console (DSCC) is the SaaS-based control plane for HPE GreenLake for Block Storage, delivering an intuitive cloud operating model and intent-based provisioning for on-premises storage.
- Question 6Beginner
Describe HPE Storage architectures and technologies · Correctly position the HPE Storage solution
A small business with a limited IT staff needs a cost-effective shared storage solution for their 3-host VMware cluster. They require basic snapshot capabilities and automated tiering between SSDs and HDDs, but do not require advanced AI-driven management or 100% availability guarantees. Which HPE array family is best suited for this environment?
Show answer & explanation
Correct answer: B
The HPE MSA (Modular Smart Array) family is specifically designed for small and medium-sized businesses (SMB) or ROBO environments. It provides cost-effective, easy-to-use shared storage with features like automated tiering and snapshots without the premium cost of enterprise arrays.
