Pass the Huawei HCIP Transmission H31-341_V2.5 Questions and answers with ExamsMirror

PWE3 tunnels can carry multiple pseudowires; they are not restricted to a single PW per tunnel.

The core component of a ROADM (Reconfigurable Optical Add-Drop Multiplexer) is indeed the Wavelength Selective Switch (WSS). The WSS enables dynamic selection and routing of optical wavelengths without converting them to electrical signals. It provides the flexibility to add, drop, or pass through wavelengths, allowing on-demand network reconfiguration. This capability supports agile wavelength management, crucial for modern elastic and automated optical networks. HCIP-Transmission documents emphasize that the WSS is the essential element that makes ROADMs programmable and adaptive, forming the backbone of flexible optical layer management.

A manual lock command prevents automatic switching.

Incorrect protection group parameters can disable failover.

If the protection channel is faulty, it cannot take over traffic.

The DWSS20 board does not support grooming of 20-degree optical signals; it is designed for other signal types or degrees.

All listed statements are disadvantages of FOADM compared to ROADM: it requires site visits for capacity or service changes, has poor wavelength flexibility due to fixed allocation, demands manual power budget adjustments onsite during expansion, and cannot provision wavelength services rapidly.

The TNG2WSMD09 board is a 9-port wavelength selective multiplexer/demultiplexer for the Super C band and supports optical power adjustment and online optical power detection.
