NEW QUESTION # 42
Which of the following statements is true?
Answer: A
Explanation:
A log is a record of events that have occurred within a system, such as a network device or an application. Logs can include information about system activity, configuration changes, and error messages. They can be used for troubleshooting, auditing, and compliance purposes. Logs can report both active (real-time) and historical events that have occurred within a system.
Alarms and conditions, on the other hand, are used to notify operators of real-time status of the node, such as when a threshold is breached or when a specific event occurs. Alarms and conditions are typically used to provide real-time notifications of potential problems or issues, while logs are used to provide a historical record of what has occurred.
NEW QUESTION # 43
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.
NEW QUESTION # 44
What is the meaning of demand in EPT?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:
In the context of the Nokia 1830 Engineering and Planning Tool (EPT)-now known as WaveSuite Planner (WS-P)-a Demand is a fundamental planning object that represents the customer's traffic requirement between two or more nodes. Specifically, it refers to one or more client signals that need to be transported across the optical network. When a user defines a demand in EPT, they specify the source and destination nodes, the type of client service (e.g., 10GE, 100GE, or STM-64), the quantity of these services, and the required protection level (e.g., Unprotected, 1+1, or O-SNCP).
The tool uses these defined demands to calculate the most efficient optical path, select the appropriate hardware (transponders and muxponders), and determine the necessary wavelength assignments. While a demand eventually results in the creation of optical trails and utilizes network element capacity, the term itself strictly refers to the input traffic requirement or the client signal(s) that the network is being designed to carry. Without defining demands, the planning tool cannot generate a Bill of Materials (BOM) or perform power balancing simulations, as it wouldn't know the traffic load the physical infrastructure must support.
NEW QUESTION # 45
Where is the OPS card equipped to provide the optical channel protection?
Answer: A
Explanation:
According to the Nokia's 1830 Photonic Service Switch (PSS) product documentation, the Optical Protection Switching (OPS) card is equipped in the transponder and is responsible for providing optical channel protection between the transponder and the amplifiers. The OPS card monitors the optical signal and switches to a pre-configured protection path in case of signal degradation or loss.
NEW QUESTION # 46
Is it possible to modify node parameters within the edit EPT menu?
Answer: D
Explanation:
Yes, the user can apply manual changes but only for non-GMPLS nodes, as the control plane reserves node resources not editable by the user. The edit EPT menu allows the user to view information about a node but is not used to modify node parameters. The user can only apply manual changes to non-GMPLS nodes, as the control plane reserves node resources which cannot be modified by the user.
