A Data Protection Specialist is reviewing the system event logs of an HPE Nimble storage array.
The array is hosting a critical Oracle database volume.
[System Event Log - 04:00:00 AM]
Warning: Snapshot creation skipped for Volume Collection 'Oracle_DB_VolCol'.
Reason: Maximum snapshot retention limit reached (10,000 snapshots).
The administrator investigating the issue reveals they configured an extremely aggressive policy:
Take a snapshot every 5 minutes and retain all of them locally for 1 year.
How does the storage array's architecture fundamentally handle this configuration flaw, and what is the required remediation?

• A.The storage array automatically and silently deletes the base production volume to make room for new snapshots; the specialist must instantly restore the production LUN from tape
• B.The array automatically converts the oldest snapshots into an S3 archive format, which takes 24 hours to process; the specialist must simply wait for the deduplication queue to clear before the schedule resumes
• C.The array's operating system imposes a hard architectural limit on the maximum number of retained snapshots per volume (or globally) to protect the controller's metadata processing performance; the specialist must drastically reduce the retention schedule to stay within the array's supported maximums
• D.The array relies on the host hypervisor (VMware vCenter) to execute a scheduled task to delete old snapshots; the specialist must reboot the vCenter server to force the hypervisor to clear the snapshot cache

A customer is planning a large-scale AI analytics platform using HPE GreenLake for File Storage.
Requirements:
18 PB data lake
Linux-based compute cluster
POSIX file access
Multi-GB/s throughput per node
Minimal application modifications
Which THREE statements accurately support the proposed architecture? (Choose 3.)

• A.Fibre Channel is mandatory for AI environments exceeding 10 PB
• B.SMB provides superior throughput for Linux HPC and AI workloads
• C.NFS over RDMA allows applications to retain POSIX semantics while reducing TCP/IP stack overhead
• D.RDMA-capable networking can improve throughput efficiency while reducing host CPU utilization
• E.Existing applications can continue utilizing traditional file system interfaces without requiring S3 API rewrites

A Cloud Storage Operations Analyst is reviewing a dashboard during a utilization baseline analysis for a mid-sized enterprise. The customer is concerned about rapid storage growth.
Dashboard Metrics (Last 30 Days):
Volume: PROD_DB_VOL_01
Allocated (Raw): 10 TB
Written (Host): 8.5 TB
Used (Physical): 3.2 TB
Data Reduction Ratio: 2.6:1
Thin Provisioning Savings: 1.5 TB
Daily Growth Rate: +50 GB/day
Based on the dashboard metrics, which conclusion accurately describes the current utilization state of this volume?

• A.The physical storage array will run out of capacity within 30 days based on the current 50 GB/day growth rate
• B.The volume requires immediate expansion because the host-written data has exceeded 80% of the raw allocated capacity
• C.The physical storage consumption is growing at a slower rate than the host-written data due to the active data reduction ratio
• D.The thin provisioning savings indicate that 1.5 TB of data has been permanently deleted and zero- reclaimed by the array

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

An HPE InfoSight predictive analytics report identifies a rapidly deteriorating capacity forecast.
[Capacity Forecast Dashboard]
Physical Capacity Used: 560 TB
Physical Capacity Free: 34 TB
Forecasted Exhaustion: 21 Days
Application Growth: 0.9 TB/Month
Snapshot Growth: 24 TB/Month
Recent Changes:
Immutable Snapshot Policy Enabled
Retention Increased from 14 Days to 365 Days
Ransomware Protection Policy Applied
Which THREE conclusions are supported by the available telemetry? (Choose 3.)

• A.Enabling ransomware protection automatically disables data reduction technologies
• B.Retention policies should be reviewed before purchasing additional storage capacity
• C.Long-lived immutable recovery points are likely retaining changed blocks that would otherwise be reclaimed
• D.Fibre Channel congestion is preventing snapshot metadata cleanup operations
• E.Snapshot retention changes are contributing more significantly to capacity growth than application growth
