Nokia Optical Networking Fundamentals Sample Questions (Q59-Q64):

NEW QUESTION # 59
What is the OAMP LAN interface?

A. It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management
B. It is an RJ-45 interface (a common Ethernet port) used to export active alarms to an external device, typically equipped with several LEDs
C. It is an RJ-45 interface (common Ethernet port) used to connect one or more client ports (e.g., 1Gb/s or legacy 100Mbit/s client flows)
D. It is an RJ-45 interface (a common Ethernet port) used for cascading 1830 PSS nodes (e.g., external shelves)

Answer: A

Explanation:
It is an RJ-45 interface (a common Ethernet port) that has to be configured with an IP address for node reachability and management. This interface is used to connect the OAMP node to the LAN, allowing it to be managed and monitored remotely.

NEW QUESTION # 60
Which of the following are the main reasons for fiber attenuation?

A. Small channel spacing
B. Refraction and reflection
C. Scattering and absorption
D. Chromatic dispersion (CD) and polarization mode dispersion

Answer: C

NEW QUESTION # 61
What is the definition of OSNR?

A. The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.
B. The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.
C. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.
D. The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber including both signal and optical noise.

Answer: A

Explanation:
The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth. This is also known as the signal-to-noise ratio (SNR), and it is a measure of how much signal is present in the optical signal compared to the noise, usually expressed in decibels (dB).

NEW QUESTION # 62
Which of the following sentences about FlexGrid is false?

A. Channels in FlexGrid systems are allocated with a granularity of 27.5GHz.
B. FlexGrid systems use specific sets of boards. Old generation WDM systems need to be upgraded to support FlexGrid.
C. The FlexGrid is currently standardized by ITU-T.
D. FlexGrid allows a more efficient channel spacing.

Answer: B

Explanation:
FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

NEW QUESTION # 63
Which of the following is NOT a troubleshooting functionality of the Wavelength Tracker?

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

Answer: C

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.
