Nokia Certified Network Professional – IP/MPLS Services — Question 43

Which of the following statements about the ODUk unit is TRUE?

Answer options

• A. The ODUk contains the FEC.
• B. The ODUk is the basic payload that can be electronically groomed and switched in the OTN network.
• C. The ODUk is processed at an optical level.
• D. The ODUk is the first container in which the client signal is inserted.

Correct answer: B

Explanation

The correct answer is B because the ODUk is indeed the basic payload in the OTN network that can be groomed and switched. Option A is incorrect as the FEC is not contained within the ODUk itself but is applied at different layers. Option C is wrong since the ODUk is processed at the digital level rather than the optical level. Option D is misleading because while the ODUk does carry client signals, it is not the very first container in the hierarchy.
