HPE Storage Fundamentals 認定 HPE0-J81 試験問題 (Q17-Q22):

質問 # 17
A financial institution requires a storage solution to support a high-volume transactional database with minimal latency. Which HPE block storage product would be suitable because of its ability to provide low latency and high availability?

A. HPE Alletra 9000 (Primera and 3PAR)
B. HPE Alletra Storage MP B10000
C. HPE Alletra 5000 and 6000 (Nimble 5000 and 6000)
D. HPE MSA

正解：A

解説：
A high-volume transactional database for a financial institution places two demands on the array at once:
consistent low latency under heavy random I/O, and continuous availability, since any interruption affects payments and customer activity. These are tier-0 and tier-1 requirements, and the product choice should follow them.
The HPE Alletra 9000, which carries forward the Primera and 3PAR architecture, is positioned for mission- critical workloads. Its multi-node, active-active design with a shared-everything approach, all-NVMe media, and dedicated ASIC-assisted data handling provide predictable sub-millisecond response and the ability to survive component and node failures without interruption. HPE backs the platform with a data availability guarantee, which is the type of assurance a financial institution requires.
Alletra 5000 and 6000, derived from Nimble, are strong in predictive analytics and cost-efficient general- purpose workloads, and Alletra 6000 serves business-critical applications, but the 9000 is the platform designed for the most demanding latency and availability tier. Alletra Storage MP B10000 is a newer disaggregated platform aimed at broader consolidation and cloud-native operation. HPE MSA is an entry- level array for small and mid-sized environments and does not carry mission-critical latency or availability commitments. Option A best matches the scenario.

質問 # 18
A storage administrator notices that a volume's snapshots are consuming increasing amounts of capacity over time. What is the most likely cause?

A. The array's cache has been disabled
B. RAID rebuild is in progress
C. Snapshots are static and never grow
D. Underlying data blocks are changing, causing snapshots to retain more delta data

正解：D

解説：
Snapshots typically only store changes (deltas) from the point they were taken; as more of the underlying data changes, the snapshot retains more delta data and grows in size.

質問 # 19
What is a key benefit of maintaining firmware consistency and version recency across controllers, drives, and enclosures?

A. Ensuring background scrubbing is automatically performed for data integrity
B. Guaranteeing the presence of spare capacity for emergencies
C. Facilitating the use of secure protocols such as HTTPS and SMI-S over long uptimes
D. Enhancing system stability and compatibility with new features

正解：D

解説：
Keeping firmware current and consistent across all components reduces interoperability issues and ensures the system can support new features and fixes, improving overall stability.

質問 # 20
What advantage does the air-gapped nature of tape storage provide in the context of cybersecurity, and how does it influence disaster recovery strategies?

A. It reduces storage costs by minimizing the need for redundant backup systems.
B. It prevents unauthorized access by keeping data offline, enhancing protection against ransomware.
C. It enhances scalability by allowing seamless integration with cloud-based services.
D. It allows for faster data retrieval, improving recovery times during network failures.

正解：B

解説：
An air gap is a physical or logical separation that leaves no network path between a data copy and any system an attacker might control. Tape provides this property naturally. A cartridge outside a drive, whether stored in a library slot or in an offsite vault, is not reachable by malware, compromised credentials or a rogue administrator.
This directly counters ransomware, which commonly encrypts or deletes online backups before triggering the main attack. Any copy that remains disconnected stays intact, so the organisation holds a known-good recovery source when everything else is compromised. The effect on disaster recovery planning is significant.
Tape becomes the last-resort tier in a layered strategy, for example the offline copy in a 3-2-1-1-0 design, and recovery runbooks include a defined path for restoring from vaulted media when online repositories cannot be trusted.
Option B is incorrect because air-gapping is about isolation, not integration with cloud services. Option C is incorrect because tape is an additional protection layer and does not remove the need for redundancy. Option D is incorrect because tape retrieval is not faster than disk; recovery time is generally longer due to media handling and sequential access. Option A correctly links offline storage with protection against unauthorized access and ransomware.

質問 # 21
How does HPE GreenLake's approach to capacity deployment and pricing contribute to cost efficiency and business agility for customers?

A. By providing fixed capacity options that ensure consistent pricing regardless of usage, allowing for predictable resource allocation.
B. By focusing solely on public cloud solutions, ensuring customers can transition entirely away from on- premises infrastructure.
C. By enabling customers to scale capacity in minutes and reducing unit charges as usage increases, allowing for cost reductions.
D. By offering a one-time upfront investment model that eliminates variable costs and promotes long-term financial stability.

正解：C
