Huawei H31-311_V2.5 Exam - Topic 1 Question 39 Discussion

Actual exam question for Huawei's H31-311_V2.5 exam

Question #: 39
Topic #: 1

The backplane has two 48V power cords, and each board gets two -48V power supplies from the backplane. After combining the power supply via diodes, the various voltages required for each component are obtained by means of a DC/DC power module and a linear mane swap.

Agreed, but I wonder about the efficiency of those diodes.

Two 48V cords? Seems a bit overkill, don’t you think?

Definitely true, that's how backplanes work.

Wait, linear mane swap? Is that a typo?

I believe it's an error. I remember a similar question where we had to identify incorrect statements about power supply configurations.

I recall we discussed how DC/DC converters work, but I'm confused about the linear mane swap part. Is that a typo?

I'm not entirely sure, but I feel like there was a question about power distribution that mentioned linear regulators.

I think the statement is true because I remember something about power supplies being combined with diodes in our last practice exam.

This looks straightforward. The backplane has redundant 48V power, and the boards use that to generate the required voltages. Seems like a standard power distribution setup, so I'll go with True.

Wait, what's a "linear mane swap"? That part's confusing me. I'll need to double-check the terminology and make sure I understand how the power conversion is happening.

Alright, I think I got this. The various voltages are obtained by combining the power supply via diodes, then using a DC/DC power module and a linear regulator. Gotta be True.

Okay, let's see. The backplane has two 48V power cords, and each board gets two -48V power supplies from the backplane. Sounds like some kind of redundancy or backup system.

Hmm, this seems like a tricky one. I'll need to carefully read through the details and think through the power supply setup.

I'm not totally sure about this. The CIP rules can be tricky, and I don't want to overthink it. I'll just go with my gut and select B - the bank can waive parts of the requirements if there's a good reason.

Okay, let's think this through step-by-step. The key is identifying the solution that provides a seamless experience for students to select and purchase courses. I've got a strategy in mind.
