HP Storage & Backup Solutions 3 — Questions and Answers
Question 1: A healthcare customer requires their backup data to be immutable for 7 years to meet HIPAA retention requirements. Which HP StoreOnce feature addresses this?
- StoreOnce Encryption at Rest
- StoreOnce Catalyst Copy
- StoreOnce Data Immutability with WORM locking (Correct answer)
- StoreOnce Federated Deduplication
Correct answer: StoreOnce Data Immutability with WORM locking
StoreOnce WORM (Write Once Read Many) locking prevents backup data from being modified or deleted during a defined retention period, satisfying HIPAA compliance.
Question 2: In HP 3PAR / Primera Remote Copy configurations, what does 'Synchronous' mode guarantee that 'Asynchronous' mode does not?
- Faster average write performance
- Zero RPO — no data loss if the primary array fails (Correct answer)
- Automatic failover without administrator intervention
- Support for replication over high-latency WAN links
Correct answer: Zero RPO — no data loss if the primary array fails
Synchronous Remote Copy waits for the secondary array to acknowledge each write before confirming to the host, guaranteeing zero data loss (RPO=0).
Question 3: Which HP storage platform is purpose-built as a scale-out object storage solution designed for unstructured data at petabyte scale?
- HP Nimble Storage HF Series
- HP StoreOnce 5650
- HP Scality RING (HP branded)
- HP Apollo 4000 with StoreAll (Correct answer)
Correct answer: HP Apollo 4000 with StoreAll
HP Apollo 4000 servers running HP StoreAll software deliver a scale-out object/file storage platform built for petabyte-scale unstructured data.
Question 4: When HP Nimble Storage reports a 'cache hit ratio' of 95%, what does this indicate about workload performance?
- 95% of write operations completed without a disk flush
- 95% of read requests were served from flash cache, avoiding slow HDD reads (Correct answer)
- The array is using 95% of its available flash capacity
- 95% of backup jobs completed successfully within the cache window
Correct answer: 95% of read requests were served from flash cache, avoiding slow HDD reads
A 95% cache hit ratio means nearly all read I/O is served from fast flash, significantly reducing latency compared to reading from spinning disk.
Question 5: What is the role of HP StoreEver Command View software in a tape library environment?
- It performs data deduplication before writing to tape
- It provides centralized management, monitoring, and reporting for HP tape libraries (Correct answer)
- It encrypts backup data using AES-256 before sending to the tape drive
- It converts LTO tape cartridges to virtual tape library format
Correct answer: It provides centralized management, monitoring, and reporting for HP tape libraries
HP StoreEver Command View TL is the management software that provides a unified interface for configuring, monitoring, and generating reports for HP tape libraries.
Question 6: A company wants to use their HP Primera array to take application-consistent snapshots of a Microsoft SQL Server database. Which integration method ensures SQL VSS writer coordination?
- HP Recovery Manager Central (RMC) with Microsoft VSS provider (Correct answer)
- HP StoreOnce Catalyst with SQL native backup
- HP 3PAR Remote Copy with synchronous replication
- HP Nimble Storage Connection Manager
Correct answer: HP Recovery Manager Central (RMC) with Microsoft VSS provider
HP Recovery Manager Central integrates with the Microsoft VSS framework to quiesce SQL Server and take application-consistent snapshots on HP Primera/3PAR arrays.
Question 7: Which LTO generation introduced the LTFS (Linear Tape File System) standard, allowing tape cartridges to be accessed like a USB drive?
- LTO-4
- LTO-5 (Correct answer)
- LTO-6
- LTO-8
Correct answer: LTO-5
LTFS was introduced with LTO-5, enabling a self-describing file system on tape that allows drag-and-drop file access without specialized backup software.
