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).

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.

Yeah, I agree. It wouldn't make sense for them to share the same ODN with such different wavelengths.

I think option D is incorrect too. The wavelengths of GPON and XGS-PON are not compatible.

Option C is definitely wrong. The deployment of WDM1r multiplexers absolutely affects the calculation of optical link attenuation.

Yes, you're right. Option C is definitely wrong. WDM1r multiplexers do impact the calculation of optical link attenuation.

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.
