**Question 1. Which component in Hitachi NAS (HNAS) hardware provides
hardware‑accelerated processing for file system operations?**
A) CPU
B) FPGA
C) GPU
D) ASIC
Answer: B
Explanation: The Field Programmable Gate Array (FPGA) offloads and accelerates NAS
operations such as compression and deduplication, improving performance.
**Question 2. In a clustered HNAS deployment, what term describes the two nodes that
provide high‑availability?**
A) Active‑Passive Pair
B) HA Node Pair
C) Dual‑Controller Set
D) Redundant Array
Answer: B
Explanation: An HA (High‑Availability) node pair consists of two HNAS nodes that monitor each
other and take over services if one fails.
**Question 3. Which interface is used by HNAS to connect to a Hitachi Virtual Storage Platform
(VSP) back‑end?**
A) iSCSI
B) Fibre Channel (FC)
C) InfiniBand
D) Ethernet

Certification Exam Preparation
Answer: B
Explanation: HNAS integrates with VSP via Fibre Channel, providing block‑level connectivity for
high‑speed data transfers.
**Question 4. What is the primary purpose of the Virtual System Management Unit (vSMU) in
HNAS?**
A) Data compression
B) Remote system monitoring and configuration
C) File system creation
D) Snapshot management
Answer: B
Explanation: The vSMU provides a virtualized management interface for configuring and
monitoring the HNAS system without requiring physical SMU hardware.
**Question 5. Which port type on an HNAS node is typically used for management traffic?**
A) EVS data port
B) Cluster interconnect port
C) Management Ethernet port
D) Fibre Channel port
Answer: C
Explanation: The dedicated management Ethernet port handles CLI, web UI, and SNMP traffic,
separating it from data traffic.
**Question 6. Hitachi Dynamic Provisioning (HDP) primarily provides which benefit for NAS
volumes?**
A) Fixed allocation of space per file

Certification Exam Preparation
B) Automatic thin provisioning and space reclamation
C) Encryption at rest
D) Multi‑protocol support
Answer: B
Explanation: HDP enables thin provisioning, allocating space on demand and reclaiming unused
space, optimizing storage utilization.
**Question 7. How does Hitachi Tiered Storage (HDT) improve performance for active data?**
A) By replicating data across all nodes
B) By moving hot data to faster tiers automatically
C) By compressing all data equally
D) By disabling snapshots on cold data
Answer: B
Explanation: HDT automatically tiers data based on usage patterns, placing frequently accessed
(hot) data on high‑performance media.
**Question 8. Which quota type limits the total space a specific directory can consume?**
A) Virtual Volume Quota
B) File System Quota
C) User Quota
D) Group Quota
Answer: B
Explanation: File System Quotas are applied at the directory or user level within a file system to
restrict storage consumption.

**Question 9. What is the main advantage of hardware‑accelerated compression on HNAS?**
A) Reduces CPU load while increasing effective capacity
B) Provides encryption keys automatically
C) Enables instant snapshots
D) Allows cross‑protocol file sharing
Answer: A
Explanation: Hardware compression offloads work from the CPU, delivering higher throughput
and better storage efficiency.
**Question 10. Which service enables HNAS to archive data to an object‑based storage tier?**
A) NDMP
B) HDRS (Hitachi Data Repository Service)
C) iSCSI Target
D) NFSv4.2
Answer: B
Explanation: HDRS integrates HNAS with object storage, allowing tiered archiving of infrequently
accessed data.
**Question 11. Which file sharing protocol does HNAS support for Windows clients?**
A) NFS
B) SMB/CIFS
C) FTP
D) S3
