HPE Storage Fundamentals (HPE0-J81) Certification Sample Questions

01. An administrator at a seed-research company is cabling two new drive enclosures behind an HPE MSA controller enclosure. Each drive enclosure has two I/O modules, A and B. A colleague proposes cabling only the A-side modules to save time, arguing that the array already has redundant controllers.
What is the risk in this proposal, and what should be done instead?
a) One cable or I/O module fault cuts off the enclosures; cable both A and B
b) Only half of each enclosure's drives can be used; cable the B side to unlock the rest
c) B-side modules stay idle until firmware enables them; skip that cabling
d) No risk exists, as the redundant controllers already cover any cable or module fault on the back end

02. A food-processing company failed its ERP VMs over to its DR site with HPE Zerto after a flood at the main site. The main site is now repaired, and the ERP has been running and changing at the DR site for two weeks.
Which two steps return the ERP to the main site without losing those two weeks of changes?
(Choose TWO.)
a) Replicate the main site's original ERP volumes forward to the DR site again
b) Once the sites are synchronized, run a planned Zerto move back to the main site
c) Restore the ERP VMs at the main site from the last backup taken before the flood
d) Re-protect the VPG so Zerto replicates from the DR site back to the main site

03. At an online travel agency, the capacity trend for an HPE Alletra Storage MP B10000 in Data Services Cloud Console shows free space shrinking fast, yet application data has barely grown. The console attributes the growth to snapshots. Last month a new protection policy began keeping hourly snapshots for 180 days, although the recovery requirement is 14 days.
What should the storage team do first, without buying hardware?
a) Add controller nodes so that the snapshots are processed faster
b) Add capacity enclosures to restore the lost headroom
c) Cut the policy's snapshot retention to match the 14-day requirement
d) Convert the application volumes from thin to fully provisioned

04. A ferry operator runs active peer persistence between two HPE Alletra Storage MP B10000 arrays at two sites. The design review asks how the arrays avoid both sides continuing to serve the same volumes independently if the replication links between the sites fail while both arrays stay up.
Which design element addresses this concern?
a) More frequent snapshots on both arrays for as long as the link outage lasts
b) Multipath I/O on every host with paths to both arrays
c) Asynchronous replication between the sites in place of synchronous replication
d) A quorum witness at a third site that decides which array keeps serving

05. Developers at a crop-science institute need a fresh, writable copy of a large production database on its HPE Alletra Storage MP B10000 every morning for testing. The storage budget rules out keeping several full-size copies of the data.
Which approach meets this need on the array?
a) Writable snapshots of the production volumes, refreshed daily
b) Restoring last night's HPE StoreOnce backup to new volumes each morning
c) Asynchronous replication of the volumes to a second B10000
d) Copying the database files into an HPE Alletra Storage MP X10000 bucket

06. An hour ago, a faulty script corrupted tables in a database stored on an HPE Alletra Storage MP B10000 volume. The volume has hourly snapshots on the array and is also synchronously replicated to a second B10000.
Which option returns the volume to its state before the script ran most quickly?
a) Let RAID parity rebuild the corrupted blocks from the other drives
b) Recover the database from last week's full backup on tape
c) Fail over to the synchronous replica on the second B10000 array
d) Restore the volume from the snapshot taken before the script ran

07. A regional airline is moving its crew-scheduling and maintenance databases to an HPE Alletra Storage MP B10000. On the old array every volume was fully allocated when it was created. The volumes total 240 TB as provisioned, but the databases have written only about 110 TB, and much of that data repeats.
Which two B10000 capabilities reduce the NVMe capacity these databases will consume?
(Choose TWO.)
a) Thin provisioning, which allocates flash only as data is written
b) QoS policies that cap the IOPS each database volume can use
c) Deduplication and compression of the data written
d) Volume sets, so the data and log volumes are snapshotted together

08. A staff member at a property developer deleted an important spreadsheet about 20 minutes ago from a file-server VM protected by HPE Zerto. The VM's datastore volume is also replicated synchronously to a DR array, and nightly backups go to HPE StoreOnce. The VM itself is healthy and must keep running for everyone else.
Which approach recovers just that file, as it was before the deletion?
a) Revert the VM's datastore volume to this morning's array snapshot
b) File-level restore from a recent journal checkpoint
c) Bring up the array-replicated copy of the volume at the DR site
d) Restore the VM from last night's StoreOnce backup

09. A seafood distributor restores individual files several times a week and wants those restores to be fast. It also wants a copy that is offline and off-site for disaster and ransomware recovery, and has chosen a disk-to-disk-to-tape (D2D2T) design.
Which two elements belong in this design?
(Choose TWO.)
a) Backups written straight to tape, then copied to disk once a month
b) Synchronous replication of production volumes to a second array
c) Copies from StoreOnce to StoreEver tape, vaulted off-site
d) Nightly backups to a StoreOnce appliance for quick operational restores

10. A county records office keeps nightly backups of its file servers for 30 days. The records manager now wants closed court files moved off production storage and kept, searchable, for several decades. The nightly backups will continue unchanged.
Which statement explains why this request calls for an archive rather than longer backup retention?
a) An archive keeps data long term for retention and reference, while a backup exists for recovery
b) An archive is the latest incremental, kept after the full backup expires
c) An archive keeps several recent versions of each file so that failed servers can be rebuilt quickly
d) An archive is a synchronously replicated copy held on a second array
