Huawei H35-210_V2.5 Exam - 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).

D is true, their wavelengths don’t overlap, so sharing is fine.

Wait, can XGS-PON and GPON really share an ODN? That seems off.

I have a feeling that C might be incorrect because I think WDM1r multiplexers could influence attenuation, but I need to double-check my notes.

I feel confident that D is correct since the wavelengths don’t overlap, but I’m a bit unsure about the implications for the ODN.

Okay, let me think this through. Multipathing is typically used for iSCSI and Fibre Channel storage, so I'd expect options B and C to be correct. Local disks and NFS storage usually don't require multipathing, so A and D are likely not the right answers.

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.

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.
