질문 # 39
How are the EPT systems related to NFM-T when CPB is performed?

A. The systems are not reported on CPB, but only through the Equipment Manager
B. The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step
C. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together
D. The systems are displayed on the CPB panel and they can be individually selected

정답：D

설명：
The EPT systems are displayed on the CPB (Commissioning Parameter Builder) panel and they can be individually selected. This allows the user to configure the network elements in the network and provision them according to their specific requirements. The systems are not reported on CPB, but through the Equipment Manager. The Equipment Manager is the interface used to configure the network elements and the EPT systems. The NFM-T is not related to the CPB and does not affect the CPB process.

질문 # 40
What does it take to get connected to the NSP platform?

A. A browser and the NSP IP address; and from the landing page, the NSP application should be downloaded and launched.
B. A browser and the NSP IP address. Then, a browser plugin needs to be installed and the laptop rebooted before the NSP can be correctly reached.
C. The NSP package should be downloaded from the Nokia website and properly licensed for the specific workstation to be used.
D. A browser, the NSP IP address, and the credentials to access the web-based interface (WebUI).

정답：D

설명：
To get connected to the Nokia Service Platform (NSP) platform, you need a browser and the NSP IP address. Then, you need the credentials to access the web-based interface (WebUI) for the NSP platform. Once you have these, you can access the NSP platform from a web browser.

질문 # 41
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?

A. Detecting unexpected or missing channels.
B. Performing channel power monitoring.
C. Testing a node's internal fiber connectivity before service provisioning.
D. Tracing a service along an optical path.

정답：C

설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Nokia Wavelength Tracker is a unique and powerful technology used within the 1830 PSS portfolio to provide "layer 0" visibility. It works by embedding unique optical signatures (keys) onto each wavelength at the source (transponder). These signatures allow the system to identify and monitor individual channels as they traverse the optical network without the need for expensive Optical Spectrum Analyzers (OSAs) at every site.
Specifically, the Wavelength Tracker enables tracing a service along its path by identifying these unique keys at various monitoring points. It also excels at channel power monitoring, as it can measure the power level of each specific wavelength independently. Furthermore, it is instrumental in detecting unexpected or missing channels (ghost signals or misrouting) by comparing the detected keys against the expected provisioning data in the management system. However, it is not used for testing a node's internal fiber connectivity before service provisioning. Internal fiber connectivity is typically verified during the commissioning phase using the Commissioning and Power Balancing (CPB) tool within WS-NOC or through manual physical inspection and "fiber-it" procedures. Wavelength Tracker requires an active, keyed optical signal to function, which generally exists only during or after the service provisioning stage.

질문 # 42
What is the main function of an optical amplifier?

A. Compensating for optical power attenuation
B. Compensating for attenuation through an optical-electrical-optical amplification
C. Compensating for chromatic dispersion
D. Demodulating the incoming signal

정답：A

설명：
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.

질문 # 43
What is the metro area network?

A. The metro area network is made of OCS/SWDM nodes only, as no pure photonic nodes are used here.
B. The metro area network is located in between two access area networks and made of photonic nodes only (no OCS/SWDM nodes are used there).
C. The metro area network is located between access and core domains.
D. The metro area network is that portion of network that passes through a city to provide connections to several customers.

정답：D

설명：
The Metro Area Network (MAN) is a telecommunications network that spans a metropolitan area and connects multiple local area networks (LANs) or business networks together. It typically covers an area that is larger than a LAN but smaller than a wide area network (WAN). The purpose of a MAN is to provide a high-bandwidth, low-latency communication infrastructure for businesses and other organizations in a metropolitan area.
