A customer is using HPE StoreOnce VSA as a NAS target in a remote office backup architecture.
Which feature allows the customer to perform a deduplication-optimized copy to the central office?
A.
hash-based
B.
remote snapshots
C.
low bandwidth replication
D.
catalyst-based replication

Yes, it could be low bandwidth replication, but I don’t think that’s the feature they are referring to here, as the learner guide for HPE0-J77 addresses catalyst-based replication/deduplication through low bandwidth replication multiple times. With the way the question is phrased, and it specifically states “deduplication-optimized copy” also suggests they are referring to catalyst-based replication.
From the student guide for HPE0-J77 course:
“Learning Check
Which HPE solution consists of a disk-based storage applicance for backing up network media servers or PCs to target devices on the appliance and supports source and target deduplication?
a) StorServ Remote Copy
b) StoreOnce Catalyst remote site replication
c) StoreAll Backup to StoreEver tape storage with Symantec NetBackup
d) StoreServ File Persona Share Backup”

I think the part about the remote office branch, being an indicator of less networking performance compared to where the Central StoreOnce device, is the smoking gun. In the Learning Check question, StoreOnce is the only answer that has the ability to do Source and Target Deduplication. With the above question, StoreOnce does all of them, but the Low bandwidth option is the most correct.
See Technical White Paper here page 3 where it talks about Deduplication-Enabled Replication
