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

Which of the following statements are incorrect ?
A) WDM1r multiplexers can be deployed close to the CO or user as required.
B) GPON 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.
C) The deployment of WDM1r multiplexers does not affect the calculation of optical link attenuation.
D) Because 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.

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.
