A Backup and Recovery Engineer is reviewing a long-term capacity forecast generated by a custom script via the storage array's REST API. The script is designed to project when the secondary backup tier will run out of space.
{
"forecast_model":
"linear_regression",
"target_system":
"StoreOnce_Archive_Tier",
"current_consumption_tb": 120,
"historical_growth_avg_tb_per_month": 5,
"new_workload_scheduled":
"Encrypted_Video_Surveillance_30TB_Initial",
"projected_exhaustion_months": 15
}
Which TWO statements identify critical anti-patterns within this automated growth projection methodology? (Choose 2.)

• A. The projection model assumes that the Fibre Channel replication link has sufficient bandwidth to transport the new surveillance data within the backup window
• B. The methodology incorrectly calculates the exhaustion period by assuming the 30TB initial workload will immediately deduplicate at the historical average ratios
• C. The forecast ignores the impact of overlapping snapshot retention expiration cycles, which typically cause backup tier growth to follow a stepped, non-linear trajectory
• D. The API script fails to account for the mandatory 20% headroom buffer required on StoreOnce appliances to perform secure erase operations
• E. The script utilizes a basic linear regression model, failing to account for the compound data reduction impact of adding a massive influx of incompressible encrypted video data

An HPE InfoSight Cross-Stack Analytics report identifies the following anomaly.
[Performance Telemetry]
Array Latency: 0.7 ms
Host Latency: 21 ms
Controller CPU: 43%
SSD Utilization: 36%
Additional Findings:
Unsupported NCM Version
Unsupported HBA Firmware
Supported Array OS
Which THREE recommendations should be completed before considering hardware expansion?
(Choose 3.)

• A. Validate all host-side software through SPOCK
• B. Add SSD capacity because host latency exceeds 20 ms
• C. Upgrade unsupported multipathing software
• D. Upgrade storage controllers because host latency indicates controller saturation
• E. Upgrade unsupported HBA firmware

An Infrastructure Capacity Planner is reviewing telemetry from an HPE Alletra Storage MP deployment.
[Capacity Dashboard]
Physical Used: 385 TB
Physical Free: 42 TB
Logical Consumed: 1.7 PB
Data Reduction Ratio: 4.4:1
Average Growth: 8 TB/month
Forecasted Physical Exhaustion: 6 Months
Forecasted Logical Exhaustion: 31 Months
Several application owners have requested an immediate storage purchase because they believe the array is nearly full.
Which THREE conclusions should the planner communicate? (Choose 3.)

• A. The current data reduction ratio should be ignored because effective capacity calculations are not valid for enterprise planning
• B. Future expansion planning should be based primarily on physical growth trends rather than logical allocation alone
• C. The logical consumption figure proves that the array is operating beyond supported design limits
• D. The primary near-term risk is physical capacity exhaustion rather than logical allocation limits
• E. Data reduction technologies are currently providing significant capacity savings and extending platform life

A Storage Procurement Specialist is preparing a final design review before approving an HPE Alletra Storage MP purchase.
Requirements:
VMware vSphere
Oracle RAC
Fibre Channel
Remote Replication
Future NVMe expansion
Which THREE validation activities should be completed before approval? (Choose 3.)

• A. Verify host, firmware, and software interoperability through SPOCK
• B. Generate test snapshots to evaluate retention efficiency
• C. Review component capabilities and requirements through QuickSpecs
• D. Validate hardware compatibility and configuration rules through OneConfig
• E. Execute a RAID rebuild simulation to validate future supportability
