질문 # 33
Where can the user set the long-haul WT decoder parameter, when designing a network with EPT?

A. In the network parameters
B. In the NE parameters
C. In the audit menu
D. In the optimization parameters

정답：B

설명：
The long-haul WT decoder parameter can be set in the NE parameters when designing a network with EPT. This parameter is used to adjust the sensitivity of the decoder and can help to improve the accuracy of the measurements for long-haul WTs.
The Network Element (NE) parameters in EPT (Element Planning Tool) are used to configure various settings and options for the network elements in the network. The long-haul WT decoder parameter is one such setting that can be configured in the NE parameters section. The user can access the NE parameters by navigating to the NE Parameters menu within the EPT interface. The user can then select the appropriate network element and modify the settings as needed. This information can be found in the Nokia guide for EPT.

질문 # 34
What is the block that converts the colorless (or black and white) client signal to a specific optical channel in a WDM system?

A. Static filter device (SFD)
B. Dispersion compensation module (DCM)
C. Optical transponder (OT)
D. Wavelength router (WR)

정답：C

설명：
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.

질문 # 35
Which mechanisms can be put in place to increase network survivability?

A. Protection, where backup resources are allocated upon failure; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism
B. Protection, where backup resources are allocated upon failure; or restoration, where backup resources are pre-allocated and reserved
C. Protection, where backup resources are pre-allocated and reserved; or restoration, where each trail can be recovered thanks to a 1+1 protection mechanism
D. Protection, where backup resources are pre-allocated and reserved; or restoration, where backup resources are allocated upon failure.

정답：D

설명：
There are two main mechanisms that can be put in place to increase network survivability: protection and restoration. Protection involves pre-allocating and reserving backup resources so that they are ready in case of a failure. Restoration involves allocating backup resources upon failure and using a 1+1 protection mechanism to recover each trail. This ensures that the network is able to re-route traffic in the event of a failure, increasing the overall survivability of the network.

질문 # 36
What is the meaning of demand in EPT?

A. Demand refers to one or more client signal.
B. Demand refers to the required number of trails to be automatically created to meet design requirements.
C. Demand refers to the required capacity of a single network element in terms of bandwidth.
D. Demand refers to the amount of OTN interfaces within a single network element.

정답：A

설명：
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.

질문 # 37
What is a Shared Risk Group (SRG)?

A. A set of nodes that share a common risk of hardware failure
B. A set of network resources that share a common failure risk
C. A set of boards that share the same failure risk
D. A set of fibers that share the same latency risk

정답：B

설명：
According to the Nokia Optical Networking documentation, a Shared Risk Group (SRG) is defined as "a set of network resources that share a common failure risk. When a resource in an SRG fails, the other resources in the group are also affected." This can include fibers, boards, nodes, and other network resources. The SRG concept is used in network design and protection mechanisms to ensure survivability and minimal impact on service in case of a failure.
