1.A Backup and Recovery Engineer is attempting to right-size the storage capacity for an aging hybrid
array. The primary application owner claims their database only grows by 100 GB per week, yet the
storage array telemetry indicates the volume's physical footprint is expanding by 1.5 TB per week.
[Telemetry Logs - Volume: Fin_DB_01]
Mon 02:00 - Array Snap Created (Retention: 30 Days)
Tue 02:00 - Array Snap Created (Retention: 30 Days)
...
[Analytics Profile]
Host Data Change Rate: 2% Daily (Highly random overwrites)
Inline Deduplication: Disabled (Encrypted Payload)
Space Reclamation (UNMAP): Enabled & Active
Which TWO diagnostic conclusions accurately explain the massive discrepancy between the application
owner's perceived growth and the actual physical capacity consumption? (Choose 2.)
A. The application's 2% daily random overwrite rate forces the array's 30-day snapshot retention policy to
permanently lock massive amounts of modified physical blocks
B. The host application is transmitting an encrypted payload, which mathematically neutralizes the
storage array's ability to deduplicate the snapshot differentials
C. The application owner's calculation of 100 GB/week represents pure logical net-new data insertion,
ignoring the storage-level retention overhead of their own highly volatile overwrites
D. The storage controllers are suffering from severe CPU contention, which artificially inflates the physical
capacity metrics reported to the telemetry engine
E. The Space Reclamation (UNMAP) protocol is malfunctioning, trapping deleted database tables as
"active" physical blocks on the backend storage
Answer: A, C
2.A Customer Success Manager is explaining the financial benefits of modern HPE storage arrays to a
client. The client is confused by the terminology used in the capacity sizing proposal, specifically the
difference between "usable capacity" and "effective capacity."
How does the concept of "effective capacity" mathematically differ from "usable capacity" in modern HPE
storage sizing methodologies?
A. Usable capacity is the physical space available after RAID overhead, while effective capacity is the
logical space available after applying deduplication and compression ratios.
B. Usable capacity includes the buffer reserved for system snapshots, whereas effective capacity is
strictly dedicated to host-written volumes.
C. Effective capacity represents the raw, unformatted hardware space before RAID penalties, while
usable capacity represents the space after RAID is applied.
D. Effective capacity guarantees a 4:1 data reduction ratio universally across all workloads, while usable
capacity guarantees storage performance SLAs.
Answer: A
3.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.

Warning: Snapshot creation skipped for Volume Collection 'Oracle_DB_VolCol'.
