Discuss Dell D-XTR-MN-A-24 Exam Topic 2 Question 7

When preparing for a single-to-dual online cluster expansion, which power cables are pre-staged by being connected to PDU-B only?

AX1-SC1-PSU-L and X1-SC2-PSU-L

BX2-DAE-PSU-R and X2-DAE-PSU-L

CIBSW-PSU-L and IBSW-PSU-R

DX2-SC1-PSU-R and X2-SC2-PSU-R

Suggested Answer: A

In a multi-brick XtremIO X2-R array, a 36 port InfiniBand switch is used. This type of switch provides the necessary number of ports to accommodate the connectivity requirements of a multi-brick configuration, ensuring high-speed data transfer and communication between the bricks and other components of the storage array1.

The InfiniBand switch plays a crucial role in the XtremIO X2-R's architecture, as it allows for the interconnection of multiple bricks, which collectively contribute to the array's performance and scalability. The 36 port switch ensures that there are enough ports available for current use and potential future expansion1.

I agree with A, it’s always been those cables for PDU-B!

Cassie 11 months ago

Wait, are we sure about A? Seems off to me.

An 11 months ago

Definitely C, I remember that from the last setup.

Geoffrey 11 months ago

I think it might be B, but I'm not entirely sure.

Glory 11 months ago

Pretty sure it's A, those are the right cables.

Doug 12 months ago

I’m pretty certain it’s D, but I could be mixing it up with another topic. We did cover the X2 cables in a practice quiz, though.

Mike 12 months ago

I’m leaning towards C, but I’m not entirely confident. I remember discussing the importance of the IBSW cables in our study group.

Alex 12 months ago

I feel like it could be B, but I’m a bit confused. We had a similar question about power distribution units last week, and I can't recall the exact details.

Alyssa 1 year ago

I think the answer might be A, but I’m not completely sure. I remember something about those cables being specifically mentioned in our last practice session.

Portia 1 year ago

I'm not too confident about this one. The wording is a bit technical, and I'm not sure I fully understand the context. I'll take my best guess, but I might need to come back to this question later.

Anika 1 year ago

Okay, I've got this. The key is to identify which power cables are pre-staged by being connected to PDU-B only. Based on the options, I believe the correct answer is A.

Mammie 1 year ago

Hmm, I'm a bit confused by the terminology here. I'm not entirely sure what a "single-to-dual online cluster expansion" is. I'll need to think this through carefully and maybe review some notes before answering.

Mona 1 year ago

This question seems pretty straightforward. I think I can figure this out by carefully reading the options and considering the context of a "single-to-dual online cluster expansion".

Bettina 1 year ago

Hmm, this seems straightforward. I'll need to convert the time values to a common unit, like minutes, and then see which ones exceed the limit.

Katlyn 1 year ago

Hmm, this seems like a classic A/B testing scenario. I think the null hypothesis would be that the sales lifts for the two campaigns are equal.

Yuki 1 year ago

This question is making my brain hurt. I think I need to go back to the basics and study the difference between a PDU-A and a PDU-B. Or maybe I'll just ask my cat for the answer, she seems to know more about this stuff than I do.

I'm just going to go with whatever option has the most 'PSU' in it. That's gotta be the right answer, right? Power supply unit power supply unit power supply unit!

Sounds good to me. Option B it is!

Kristofer 1 year ago

Gayla 1 year ago

Option C seems the most logical to me. The IBSW-PSU-L and IBSW-PSU-R cables are the ones that need to be pre-staged, right? I mean, who doesn't love a good ol' IBSW-PSU combo?

Dick 1 year ago

↳ replying to Gayla

Great choice on option C, those are the cables needed for the expansion.

Ronny 1 year ago

↳ replying to Gayla

Definitely, it's important to have those cables pre-staged for a smooth transition.

Ashleigh 1 year ago

↳ replying to Gayla

I agree, the IBSW-PSU combo is essential for this setup.

Craig 1 year ago

↳ replying to Gayla

Yes, you're correct! Option C, IBSW-PSU-L and IBSW-PSU-R, are the power cables pre-staged for the single-to-dual online cluster expansion.

Anglea 1 year ago

Hmm, I was leaning towards option D, but now I'm questioning myself. These power cable names are like a foreign language to me.

Jamie 1 year ago

User 2: Yeah, those are the ones pre-staged by being connected to PDU-B only.

Mozelle 1 year ago

↳ replying to Anglea

User 1: I think it's A) X1-SC1-PSU-L and X1-SC2-PSU-L.

Frankie 1 year ago

I'm pretty sure it's option A. The X1-SC1-PSU-L and X1-SC2-PSU-L cables are the ones that need to be pre-staged and connected to PDU-B for a single-to-dual online cluster expansion.

Bette 2 years ago

Hmm, I see your point. But I still think A) makes more sense based on the question.

Weldon 2 years ago

I disagree, I believe the correct answer is B) X2-DAE-PSU-R and X2-DAE-PSU-L.

Bette 2 years ago

I think the answer is A) X1-SC1-PSU-L and X1-SC2-PSU-L.
