Nokia Certified Network Professional – IP/MPLS Services — Question 42

Which type of ports are present in the Colorless Wavelength Router (CWR)?

Answer options

• A. Colorless uni-directional ports only
• B. Black and white ports
• C. Colorless bi-directional ports
• D. DeMux ports

Correct answer: C

Explanation

The correct answer is C, as the Colorless Wavelength Router is designed to utilize colorless bi-directional ports for efficient wavelength routing. Options A, B, and D do not accurately represent the functionality and design of the CWR, as it specifically employs bi-directional capabilities rather than uni-directional or other types.
