질문 # 31
A user needs to check for interface details against the commands is the correct one?
정답：D
설명：
show interface 11starla 1/17/L1 detail is the correct command to check for interface details. This command will display detailed information about the specified interface, including its status, configuration, and statistics.
질문 # 32
How many PM bins can be stored, for each data collection point, on PSS systems?
정답：C
설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
Performance Monitoring (PM) is critical for maintaining the health of a Nokia 1830 PSS network. The system collects data such as FEC corrected bits, optical power levels, and ODU-layer errors. According to Nokia's standard node management architecture, each data collection point (such as an optical port or an ODU termination point) stores a specific number of historical "bins" locally on the card or the shelf controller.
The standard storage capacity for these PM statistics is 33 x 15-minute bins (covering the last 8 hours and 15 minutes of granular data) and 8 x 1-day bins (covering the last week of daily totals). Additionally, there is 1 raw bin which contains the "current" accumulating data that has not yet been shifted into a completed 15-minute or 24-hour historical bin. This allows network operators using WS-NOC (WaveSuite Network Operations Center) to retrieve recent historical performance data directly from the NE (Network Element) even if the management system was temporarily disconnected. If longer-term history is required, the management system must be configured to poll and archive these bins into its own database before they are overwritten on the hardware.
질문 # 33
In which of the following forms does the TTI byte provide information on network elements?
정답：A
설명：
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the Optical Transport Network (OTN) hierarchy, the TTI (Trail Trace Identifier) is a 64-byte overhead signal used to ensure that the source and destination of a path are correctly connected. It is part of the overhead in the OTU (Optical Transport Unit) and ODU (Optical Data Unit) layers. The TTI provides a mechanism for "path trace" to prevent misconnections. It specifically carries the SAPI (Source Access Point Identifier) and the DAPI (Destination Access Point Identifier).
These identifiers are strings that uniquely identify the source and destination ports. By comparing the "Expected SAPI/DAPI" configured on a port with the "Received SAPI/DAPI" actually coming in over the fiber, the Nokia 1830 PSS can detect fiber patching errors or cross-connect mistakes. If there is a mismatch, the system can trigger a TIM (Trace Identifier Mismatch) alarm and potentially squelch the traffic to prevent data from being delivered to the wrong customer. This is a Layer 1 (OTN) function and is entirely independent of Layer 2 MAC addresses or Layer 3 IP addresses used by the management system for DCN (Data Communication Network) connectivity.
질문 # 34
Which of the following are the main reasons for fiber attenuation?
정답：A
설명：
Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.
질문 # 35
What is the main function of an optical amplifier?
정답：D
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.
