Nokia Certified Network Professional – IP/MPLS Services — Question 40

What is the function of the express channel interface?

Answer options

• A. It enables the high speed route for all channels passing through that interface.
• B. It drops high capacity channels in the local node.
• C. It passes all the channels not terminated in the local node through the downstream node.
• D. It enables the high speed route for all channels terminated in the local node.

Correct answer: C

Explanation

The express channel interface is designed to pass all channels not terminated in the local node to the downstream node, making option C the correct answer. Options A and D incorrectly describe the functionality as it relates to high-speed routing for channels terminated in the local node, while option B misrepresents the function by suggesting that it drops channels.
