NEW QUESTION 109
Which of the following statement is correct?
- A. The optical layer path and the electrical layer path are independent. It is not necessary to delete the electrical layer path when deleting the optical layer path.
- B. When the OCh path exists, you can directly create a client path. The NMS automatically creates an ODUk path.
- C. The optical layer path must be deleted first when the electrical layer path is removed.
- D. Deactivation will delete the configuration of the U2000, which has no impact on the device side services.
Answer: A

NEW QUESTION 112
What should I pay attention to when commissioning a 100G and 10G hybrid transmission system? (Multiple Choice)
- A. For a hybrid transmission system with dispersion compensation, the dispersion compensation requirements are consistent with the requirements in a 10G non-coherent system.
- B. The optical power of the 100G signal is recommended to be higher than the optical power of the 10G signal, but not higher than the single-wave nominal value of the optical panel.
- C. In order to accurately measure the optical power of 100G wavelength, it must be debugged using a spectrum analyzer or a MAC card.
- D. Pay attention to the mixed spectrum. The spectrum of the 100G signal is wider and looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent.
Answer: A,B,C,D

NEW QUESTION 116
Which of the following description of the extended ECC is correct? (Multiple Choice)
- A. In the automatic extended ECC mode, you need to connect the Ethernet ports of the two NEs with a direct-connected network cable (or a standard network cable through B), extend the ECC, and specify the server and client.
- B. Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.
- C. Extended ECC is divided into automatic extended ECC and manual extended ECC. One network element can only support one mode at the same time. These two methods cannot be directly docked.
- D. The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.
Answer: B,C,D
NEW QUESTION 117
The transmission plane mainly performs functions such as optical signal transmission, configuration protection switching, and reconnection, and ensures the reliability of the transmitted optical signal. However, the switching action of the transport layer is performed under the influence of the management dry surface and the control plane.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION 118
The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the "IN" optical port. The RDU (ROADM Demix Unit) optical module broadcasts nine identical optical signals, which are output from the "DM1~DM8" and "ECPO" optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the "EXPI" optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the "AM1"~"AM8" optical port.
- A. FALSE
- B. TRUE
Answer: B
