Actual exam question for Dell EMC's Dell Unity Deploy 2023 Exam exam
Question #: 20
Topic #: 9
[All Dell Unity Deploy 2023 Exam Questions]

A storage administrator must configure replication from a production Dell Unity XT 680F to an offsite DR Dell Unity XT 480. Block resources must be replicated without data loss if the production site becomes unavailable. File resources can be replicated with an acceptable amount of data difference on the destination.

What replication configuration meets the requirements?

Show Suggested Answer Hide Answer
Suggested Answer: B

To meet the requirements, the replication connection mode must be set to Both, which allows both synchronous and asynchronous replication sessions to be configured on the same connection. This way, block resources can use synchronous replication, which ensures zero data loss, and file resources can use asynchronous replication, which allows some data difference on the destination. Setting Unisphere resource filtering to All is not necessary, as it only affects the display of resources in the Unisphere GUI. Setting an RPO of 0 on the synchronous replication sessions is redundant, as synchronous replication always has an RPO of 0. Configuring the replication interfaces on the 4-port mezzanine card is not relevant, as it only affects the performance and availability of the replication network.

I think the best option is to set an RPO of 0 on the synchronous replication sessions.

Hmm, D sounds interesting with the 4-port mezzanine card. Wonder if that's the secret sauce to make this work.

I'm thinking C is the best bet. Zero RPO on the synchronous sessions to ensure no data loss. That's what the question is asking for.

Option B seems like the way to go. Can't go wrong with 'Both' for replication connection mode.

Option B is a good choice. Both replication connection mode covers all bases.
