NEW QUESTION # 17
What is the purpose of the NFM-T deploy menu?
Answer: A
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 # 18
What is a degree-1 node?
Answer: A
Explanation:
A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.
NEW QUESTION # 19
What is the block that converts the colorless (or black and white) client signal to a specific optical channel in a WDM system?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
The Optical Transponder (OT) is the essential interface component in a WDM system that bridges the gap between the client-side equipment and the WDM line-side. Client signals, often referred to as "colorless" or "black and white" because they typically use standard 1310nm or 1550nm short-reach optics, cannot be directly multiplexed into a DWDM fiber because they would interfere with one another.
The Transponder performs an O-E-O (Optical-Electrical-Optical) conversion process: it receives the client's optical signal, converts it to an electrical format to perform 3R functions (Re-amplification, Re-shaping, and Re-timing) and often wraps it into an OTN (Optical Transport Network) frame, and then re-transmits it using a high-precision, ITU-T grid-compliant colored wavelength. In the Nokia 1830 PSS portfolio, these can be dedicated transponders for a single high-speed service or Muxponders, which aggregate multiple lower-speed client signals into a single high-speed "colored" line interface. Other components like the SFD are used for multiplexing those colors, and the DCM is used for managing fiber impairments, but only the Transponder performs the initial frequency conversion.
NEW QUESTION # 20
Which of the following applications is related to Wavelength Tracker tool?
Answer: D
Explanation:
Tracking the protection path for a specific wavelength. The Wavelength Tracker tool is used to track the protection path of a specific wavelength, allowing the user to quickly identify any issues that may arise and take corrective action.
Wavelength Tracker tool is a feature used to monitor and track the protection path for a specific wavelength in an optical network. It can also be used to monitor and verify the working state of the protection path, and to detect and troubleshoot protection switch events. The Wavelength Tracker tool can be used to monitor the protection path for a specific wavelength, and it can also be used to trace the end-to-end path of a wavelength through the network. This tool is typically used by network operators to monitor and troubleshoot wavelength-level issues in the network, such as protection switch events or wavelength-level performance issues.
NEW QUESTION # 21
A user needs to check for interface details against the commands is the correct one?
Answer: A
Explanation:
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.
