Nokia Certified Network Professional – IP/MPLS Services — Question 46

How can a mesh network be upgraded so that more services can be transported?

Answer options

• A. Configuring new WSS cards is the most effective way to give flexibility and network bandwidth to an existing mesh network.
• B. The Protection and Restoration Combined (PRC) mechanism can enable more bandwidth but only for the protected services.
• C. Upgrading the network to coherent transmission is the only effective way to enable more bandwidth to the existing mesh network.
• D. Upgrading link capacity and/or installing new links provides more bandwidth to the existing mesh network.

Correct answer: D

Explanation

Option D is correct because upgrading link capacity and adding new links directly increases the bandwidth available to the existing mesh network. Option A is incorrect as configuring new WSS cards may improve flexibility but does not necessarily increase overall bandwidth. Option B is not right because the PRC mechanism only benefits protected services and does not enhance the overall network capacity. Option C is also wrong because while coherent transmission can improve bandwidth, it is not the only method available.
