Correct answer: NVMe/RoCE v2

NVMe over RDMA Converged Ethernet (RoCE v2) maps NVMe commands natively over an Ethernet network using RDMA, which bypasses the host TCP/IP stack to provide extremely low latency and low CPU overhead. NVMe/TCP incurs the TCP/IP overhead, making it unsuitable given the constraints. Fibre Channel (FC) requires dedicated FC switching, not Ethernet. iSCSI utilizes TCP/IP.

Correct answer: False

False. In a block storage architecture (like SAN), the storage array provides raw block volumes (LUNs) to the host. The host operating system is entirely responsible for formatting those blocks with a file system (e.g., NTFS, VMFS, ext4) and managing file-level permissions. File storage architectures (NAS) manage the file system on the array itself.

Correct answer: Active-Active storage clustering with synchronous replication and ALUA support

To achieve zero RPO and transparent host failover across sites (like HPE Peer Persistence), the foundational architecture must utilize Active-Active storage clustering with synchronous replication over low-latency links. It also requires Asymmetric Logical Unit Access (ALUA) support on the host OS to manage optimized and non-optimized paths transparently. Asynchronous replication cannot provide zero RPO.

Correct answer: A disaggregated, shared-everything architecture allowing independent scaling of capacity and performance

The HPE Alletra Storage MP utilizes a disaggregated, shared-everything (multi-protocol) architecture. This allows compute nodes (performance) and JBOF enclosures (capacity) to be scaled independently over an NVMe fabric back-end. The Alletra 9000 is a traditional monolithic active-active architecture where controllers and capacity are more tightly coupled. Both support high availability, but the disaggregated scaling is unique to the MP line.

Correct answers: True multi-protocol access supporting NFS, SMB, and S3 simultaneously on the same dataset; Native software integration with VAST Data for scale-out performance

HPE GreenLake for File Storage is built on HPE Alletra Storage MP hardware combined with VAST Data software, providing massive scale-out performance for AI and HPC workloads. It also supports true native cross-protocol access (NFS, SMB, S3) to the same data without separate pools. It does not use proprietary ASICs for deduplication (it uses software similarity reduction) and does not natively attach to mainframes.

Correct answer: Zerto

Zerto (an HPE company) provides hypervisor-based Continuous Data Protection (CDP) that delivers RPOs in seconds and RTOs in minutes. HPE StoreOnce is a purpose-built backup appliance typically used for daily/hourly backups, not sub-minute CDP. Alletra and Nimble provide snapshots, but Zerto is the specific CDP solution for VM-level granular journaling.
