Dell EMC Exam D-UN-DY-23 Topic 7 Question 41 Discussion

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

Question #: 41
Topic #: 7

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.

I remember we discussed the importance of RPO in our last session, but I'm not entirely sure if setting it to 0 is the right approach for both block and file resources.

This seems straightforward. I'd go with option C and set an RPO of 0 on the synchronous replication sessions. That should meet the no data loss requirement for the block resources.

I'm a bit confused on the difference between the replication modes. I'll need to review my notes on synchronous vs asynchronous replication to make sure I understand the implications of each option.

Alright, I've got this. The answer is clearly option B - configure the replication connection mode to Both. That way I can meet the no data loss requirement for the block resources and the acceptable data difference for the file resources.

Okay, let's see here. The key seems to be balancing the data loss requirements for the block and file resources. I think I have an idea, but I'll double-check the options.

Hmm, this looks like a tricky one. I'll need to carefully read through the requirements and think through the different options.

Option B seems like the way to go. Both synchronous and asynchronous replication should cover all the bases.

But wouldn't configuring the replication interfaces on the 4-port mezzanine card also be important for efficient replication?

I agree with Celestina, setting an RPO of 0 ensures no data loss if the production site goes down.

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