Dell EMC Exam D-UN-DY-23 Topic 9 Question 20 Discussion

Actual exam question for Dell EMC's D-UN-DY-23 exam

Question #: 20
Topic #: 9

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?

ASet Unisphere resource filtering to All.

BConfigure the replication connection mode to Both.

CSet an RPO of 0 on the synchronous replication sessions.

DConfigure the replication interfaces on the 4-port mezzanine card.

Show Suggested 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.

Alright, time to channel my inner storage admin. I'm going with option C - got to keep that RPO at zero!

Is it just me, or does this question sound like a Dell Unity XT support hotline call? 'Have you tried turning it off and on again?'

I think configuring the replication interfaces on the 4-port mezzanine card is also important for efficient replication.

I agree with Nina, setting an RPO of 0 ensures minimal data loss in case of a disaster.

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.
