NEW QUESTION # 39
Which of the following are the main reasons for fiber attenuation?
Answer: B
Explanation:
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.
NEW QUESTION # 40
What is the purpose of the validate step in the EPT design process?
Answer: D
Explanation:
The validate step in the EPT design process is used to trigger the run design action, which is responsible for verifying the consistency of the network design and fixing any errors that may exist. During the validation process, the system will compare the configuration available on the involved network elements and the design provided by EPT, and any discrepancies will be flagged for further investigation or correction.
NEW QUESTION # 41
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?
Answer: B
Explanation:
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.
NEW QUESTION # 42
In which of the following forms does the TTI byte provide information on network elements?
Answer: B
Explanation:
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.
NEW QUESTION # 43
When monitoring the quality of the received signal in WDM, an open eye indicates:
Answer: D
Explanation:
An open eye pattern indicates that the signal is not affected by noise, and the received signal is of high quality. This is because an open eye pattern is the result of a signal that is aligned in time, and is not affected by noise or other distortions.
