問題1

An Infrastructure Capacity Planner is analyzing the capacity forecast dashboard for a heavily utilized HPE Alletra Storage MP array via Data Ops Manager.
[Data Ops Manager - Capacity Forecast Dashboard]
Volume Group: VMFS_DevTest_Clones
Logical Capacity Limit: 100 TB
Logical Consumed: 95 TB (95% Full)
Physical Capacity Consumed: 15 TB
Current Data Reduction Ratio: 6.3:1
Predicted Time to Physical Exhaustion: > 24 Months
Predicted Time to Logical Exhaustion: 5 Days
Which immediate, zero-cost operational action must the planner take based on this dashboard analysis to prevent an application outage?

A. Edit the volume group properties in Data Ops Manager to increase the Logical Capacity Limit from
100 TB to 150 TB

B. Generate an emergency purchase order for a new NVMe expansion shelf to mitigate the impending 5-day exhaustion window

C. Disable inline deduplication on the DevTest clones to relieve the metadata overhead and artificially extend the logical exhaustion date

D. Immediately execute an array-wide space reclamation (UNMAP) command to physically erase the
95 TB of logically consumed blocks

正確答案: A

問題2

A Data Protection Specialist is investigating a critical alert generated by HPE InfoSight. The array's base application growth has been completely stable, yet the predictive analytics engine forecasts complete capacity exhaustion within 15 days.
[InfoSight Wellness Report - Predictive Capacity]
Array: Alletra_Prod_01
Total Usable: 200 TB
Current Free Space: 30 TB
Base App Data Growth: 1 TB / Month
Predicted Time to Exhaustion: 15 Days
Recent System Changes: "Ransomware_Protection_Policy" applied 5 days ago Which TWO scenarios logically explain why the InfoSight growth projection engine is forecasting imminent capacity exhaustion despite low base application growth? (Choose 2.)

A. The array's inline compression ASIC has failed, forcing the 1 TB of monthly base application data to suddenly consume 15 TB of physical space per week

B. The array is performing a routine background parity scrub, which temporarily masks free space from the InfoSight predictive analytics telemetry agent

C. The Fibre Channel host bus adapters are transmitting data using mismatched block sizes, causing InfoSight to miscalculate the volumetric growth rate

D. The ransomware policy has extended the snapshot retention period indefinitely, preventing the storage system from reclaiming space from expired blocks

E. The newly applied ransomware policy is generating highly frequent immutable snapshots that are accumulating massive daily differential data changes

正確答案: D,E

問題3

A Storage Administrator is investigating an HPE InfoSight wellness alert.
[Cross-Stack Analytics]
Array Latency: 0.8 ms
Host Latency: 22 ms
Controller CPU: 41%
SSD Utilization: 33%
Additional Findings:
Multipathing Software Unsupported
HBA Driver Unsupported
Array Firmware Supported
Which THREE recommendations should be prioritized before considering hardware upgrades?
(Choose 3.)

A. Expand storage controller CPU resources because any host latency above 10 ms indicates controller saturation

B. Replace all SSD drives because elevated host latency indicates flash media degradation

C. Validate all host software against the HPE SPOCK interoperability matrix

D. Correct unsupported HBA drivers before attempting performance troubleshooting

E. Upgrade unsupported multipathing software to a supported version

正確答案: C,D,E

問題4

An Infrastructure Capacity Planner is forecasting the 3-year growth for an environment backed by an HPE Alletra 5000 hybrid array.
[Growth Forecast Requirements]
Requirement 1: Database random read I/O will increase by 40% next year (Compute/Cache bound).
Requirement 2: Archive file storage capacity will increase by 200 TB next year (Disk bound).
What is the fundamental architectural advantage of the Alletra 5000/6000 "Scale-to-Fit" design when addressing these highly asymmetrical growth requirements, compared to a traditional monolithic or hyperconverged scale-out architecture?

A. It allows non-disruptive, independent scaling of compute (upgrading the controller heads), read cache (installing more SSDs), or total capacity (adding HDD expansion shelves) precisely matching the specific bottleneck without forcing unnecessary hardware purchases

B. The architecture automatically virtualizes the connected host RAM to satisfy Requirement 1, relying solely on standard JBOD enclosures to satisfy Requirement 2

C. It requires the planner to mathematically balance the CPU-to-Disk ratio, mandating that for every
200 TB of capacity added, a new pair of symmetrically matched controller nodes must be purchased

D. The array relies on a dedicated Storage Area Network (SAN) routing protocol to migrate active workloads to older, retired storage arrays, avoiding physical expansion entirely

正確答案: A

問題5

A multinational manufacturing company is evaluating two expansion strategies.
Option A:
Purchase additional NVMe shelves immediately.
Option B:
Enable inline deduplication and compression on selected workloads.
Current Environment:
Controller CPU: 76%
Physical Utilization: 89%
Workload Mix:
VDI
VMware
Oracle Databases
Encrypted Backups
Which THREE considerations should influence the final recommendation? (Choose 3.)

A. Data reduction universally improves write latency and should therefore always be preferred over hardware expansion

B. Different workload types will achieve significantly different data reduction outcomes

C. Encrypted backup datasets often provide minimal deduplication benefit compared to VDI environments

D. Future capacity planning should account for projected growth regardless of anticipated reduction savings

E. Additional data reduction processing may increase controller resource consumption and should be evaluated against current utilization

正確答案: B,C,E

Which THREE architectural components should be included in the design? (Choose 3.)

A. Manual LUN import procedures executed after site failure

B. SPOCK-validated multipathing software to ensure supported host failover behavior

問題7

A Data Center Operations Engineer is tasked with implementing Quality of Service (QoS) on an HPE Alletra array to resolve performance complaints from the finance department. The finance database shares the array with several aggressive development workloads.
Which statement accurately defines the core mechanism by which HPE QoS policy tuning prioritizes mission-critical workloads over less critical environments?

A. QoS policies instruct the host operating systems to artificially delay their own TCP/IP packet acknowledgments, forcing the development servers to throttle their storage requests

B. QoS policies automatically migrate the active blocks of the development workloads to a secondary, lower-performing storage array transparently over the IP network

C. QoS policies establish strict Minimum IOPS guarantees to protect critical workloads from latency degradation while simultaneously applying Maximum IOPS limits to throttle noisy neighbor applications during periods of array contention

D. QoS policies dynamically reconfigure the Fibre Channel SAN zoning to physically isolate the host bus adapters of the critical workloads onto dedicated, unshared switch ISLs

正確答案: C
