Question #1
A customer runs VMware vSphere on HPE Nimble Storage arrays. Users report intermittent VM latency spikes. The customer wants to determine whether the cause is in the array, the ESXi hosts or the SAN, without manually collecting and correlating logs from each layer. Which capability should you recommend?
Correct answer: A
Explanation
InfoSight collects telemetry from the array and from vCenter and uses cross-stack analytics to point to the layer causing the latency. OneView alerts report hardware health, not latency attribution. Comparing array and vCenter charts by hand is exactly the manual correlation the customer wants to avoid.

Question #2
A customer added a new drive enclosure with SSDs to an existing HPE 3PAR StoreServ array. The existing volumes are still spread only across the original drives. Which CLI command redistributes the existing volume data across all drives, including the new ones?
Correct answer: A
Explanation
tunesys analyzes drive utilization and rebalances chunklets across all drives, including newly added ones. compactcpg only reclaims unused logical disk space in a CPG, checkvv verifies volume consistency, and growvv increases the size of a virtual volume.

Question #3
An administrator wants VMware ESXi hosts to spread I/O across all active paths to HPE 3PAR StoreServ volumes. Which path selection policy should be configured?
Correct answer: A
Explanation
Round Robin rotates I/O across all active paths and is the policy recommended for 3PAR volumes. MRU and Fixed use a single path at a time and only switch on failure.

Question #4
A customer must complete a nightly full backup of 18 TB within a 10-hour window. Incremental backups of 2 TB run on other nights and are not a constraint. The design uses a single StoreOnce backup target. What minimum sustained ingest throughput must the target deliver? (Use 1 TB = 1,000,000 MB.)
Correct answer: B
Explanation
The full backup is the sizing case: 18 TB = 18,000,000 MB over 10 h = 36,000 s, giving 500 MB/s. The 2 TB incremental does not drive the design. 1,800 MB/s comes from dividing TB by hours without converting hours to seconds correctly.

Question #5
A customer uses a backup application that supports HPE StoreOnce Catalyst. The customer has two sites and limited WAN bandwidth between them. Which two capabilities does Catalyst provide in this design? (Select two.)
Select 2 answers.
Correct answer: B, D
Explanation
Catalyst offers low bandwidth backup through source-side deduplication and lets the backup application manage and track copies between StoreOnce systems. Virtual tape emulation is a separate StoreOnce VTL presentation, and StoreOnce is a backup target, not primary block storage.

Question #6
A customer must retain 400 TB of compliance data for 10 years. The data is rarely read, and the customer wants low power consumption and protection from network-borne ransomware. A competitor is proposing a disk-only archive. Which two points support recommending an HPE StoreEver LTO tape library? (Select two.)
Select 2 answers.
Correct answer: B, D
Explanation
Tape at rest uses no power, and offline cartridges cannot be reached or encrypted over the network, which fits the rarely-read, ransomware-sensitive archive. Tape access is sequential and slower than disk for single-file retrieval, and deduplication is a feature of StoreOnce disk targets, not of the tape library.

Question #7
A customer configures ten 4 TB drives as a single RAID 6 group. Ignoring spare capacity and formatting overhead, how much usable capacity does the group provide?
Correct answer: B
Explanation
RAID 6 uses two drives' worth of capacity for dual parity, so ten drives provide (10 - 2) x 4 TB = 32 TB. The 36 TB figure is the RAID 5 result with single parity, and 20 TB is what mirroring would give. 40 TB is raw capacity.

Question #8
A customer runs a VMware vSphere stretched cluster across two data centers 12 km apart. Each site has an HPE 3PAR StoreServ 8400. The requirements are zero data loss and automatic, transparent failover of the datastores to the surviving array without administrator action. A third site has a spare virtual machine host. Which configuration should you recommend?
Correct answer: C
Explanation
Peer Persistence builds on synchronous Remote Copy, which gives zero data loss, and uses a Quorum Witness at a third site to decide automatic failover. Asynchronous modes cannot guarantee zero data loss and do not support Peer Persistence. Recovery Manager Central with scripts is a manual process, so it fails the transparent failover requirement.

Question #9
A customer will back up a 20 TB file server to a StoreOnce system. The policy is one full backup each week and a 1 TB incremental backup on each of the other six days, with four weeks of retention. The expected deduplication ratio is 10:1. What is the minimum usable capacity the StoreOnce system needs to hold the retained backups?
Correct answer: B
Explanation
Four weekly fulls are 4 x 20 TB = 80 TB, and 24 incrementals are 24 x 1 TB = 24 TB, for 104 TB of logical data. Divided by the 10:1 ratio this is 10.4 TB. 8.0 TB omits the incrementals, and 104 TB ignores deduplication.

Question #10
A media company must keep 2 PB of rarely accessed video masters for 15 years. The customer wants the lowest cost per GB and an offline copy that is protected from ransomware. A competitor has proposed an all-flash array. Which HPE solution should you position?
Correct answer: B
Explanation
Tape offers the lowest cost per GB for long-term, infrequently accessed data, and cartridges removed from the library are offline and out of reach of ransomware. LTFS lets users browse the archive like a file system. Flash and disk-based systems cost more per GB and stay online.
