NEW QUESTION # 19
Is it possible to modify node parameters within the edit EPT menu?
Answer: A
Explanation:
Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user. The edit EPT menu allows the user to view information about a node but is not used to modify node parameters. The user can only apply manual changes to non-GMPLS nodes, as the control plane reserves node resources which cannot be modified by the user.
NEW QUESTION # 20
What is the main function of an optical amplifier?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The primary function of an optical amplifier in a WDM system is to provide gain to the optical signal to compensate for optical power attenuation (loss) that occurs as light travels through the optical fiber. As photons travel through kilometers of silica fiber, their energy is absorbed or scattered, leading to a reduction in signal strength. To ensure the signal reaches its destination with sufficient power for the receiver to detect it, amplifiers like the EDFA (Erbium-Doped Fiber Amplifier) or Raman amplifiers are placed at strategic intervals along the fiber span.
It is crucial to distinguish this from Option D; modern optical amplifiers perform purely optical amplification, meaning the signal stays in the photonic domain without being converted to electricity (O-E-O). While some specialized amplifiers (like the RA2P) might interact with other parameters, their fundamental job is power restoration. Furthermore, while amplifiers are essential for a network's reach, they do not compensate for chromatic dispersion-that is the job of Dispersion Compensation Modules (DCM) or electronic dispersion compensation (EDC) in coherent transponders-nor do they demodulate signals, which is the role of the receiver in a transponder.
NEW QUESTION # 21
What is the purpose of the NFM-T deploy menu?
Answer: B
Explanation:
The NFM-T (Network Functions Manager - Transport), now part of the WaveSuite Network Operations Center (WS-NOC), is the centralized management system for Nokia's optical portfolio. The Deploy menu is the primary engine for operationalizing the network. Its fundamental purpose is to create and provision new network instances, which encompasses the lifecycle of the transport infrastructure.
Specifically, this menu allows operators to establish physical connections (fiber links between nodes), build out the infrastructure (defining the topology and node roles), and most importantly, provision services (such as ODUk or Optical Channel services). While the EPT (now WaveSuite Planner) designs the network, and those files can be used as a reference, the actual "birth" of a service in the live network-mapping it from the source transponder to the destination through the required ROADM degrees-is executed via the Deploy menu. It translates the high-level intent into specific cross-connect commands sent to the individual Network Elements (NEs), ensuring that the underlying hardware is correctly configured to carry client traffic.
NEW QUESTION # 22
With reference to the image, where is the OPS card placed to provide the OMSP protection?
Answer: A
NEW QUESTION # 23
How can a mesh network be upgraded so that more services can be transported?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
While technologies like WSS (Wavelength Selective Switches) and coherent transmission (100G/200G/400G+) significantly improve the efficiency and reach of a network, the most direct way to increase the total transportable volume of services in a mesh topology is to upgrade link capacity or install new physical links. In Nokia optical planning, upgrading link capacity typically involves moving from a lower-rate system (like 10G) to a higher-rate system (like 100G or 400G) or increasing the number of available wavelengths by expanding from a 40-channel to an 80-channel or 96-channel C-band system.
Adding new links (new fiber spans) creates more degrees in the mesh, providing more paths for traffic and increasing the overall aggregate bandwidth of the network. Option A refers to flexibility (ROADM functionality) rather than raw capacity. Option B (PRC) relates to survivability and availability, not capacity expansion. While Option C (coherent transmission) is a powerful method for increasing capacity per wavelength, it is not the "only" way, as adding more fiber (spatial multiplexing) or more channels (spectral density) are also primary methods for scaling a mesh network to handle more services.
