Huawei Exam H35-210_V2.5 Topic 1 Question 58 Discussion

Actual exam question for Huawei's H35-210_V2.5 exam

Question #: 58
Topic #: 1

Which of the following statements are incorrect ?

AWDM1r multiplexers can be deployed close to the CO or user as required.

BGPON and XGS-PON have different rates but the same network architecture. Therefore, to ensure that the device supports XGS-PON, you only need to change the optical modules on an ONU.

CThe deployment of WDM1r multiplexers does not affect the calculation of optical link attenuation.

DBecause the center wavelengths of XGS-PON and GPON are different and do not overlap or conflict with each other, they can share an optical distribution network (ODN).

I bet the network engineers who wrote this question are sitting back, sipping their coffee, and chuckling at us poor souls trying to figure this out.

Wait, is there a trick question in here? Maybe they're all incorrect, and the real answer is 'all of the above'!

Option A seems off to me. I thought WDM1r multiplexers were typically deployed closer to the CO, not the user.

I'm going to have to go with option D as the incorrect statement. There's no way GPON and XGS-PON can share the same ODN, their wavelengths are too different.

Actually, I think option A is incorrect. WDM1r multiplexers cannot always be deployed close to the CO or user as required.

But changing the optical modules on an ONU is necessary to support XGS-PON, so statement B is correct.

I'm pretty sure option B is incorrect. GPON and XGS-PON have different network architectures, so you can't just swap out the optical modules on an ONU to support XGS-PON.
