NEW QUESTION 117
Which of the following statements are wrong about TE links? (Multiple Choice)
- A. The TE link path is a resource concept. It can be understood as an optical fiber with bandwidth information and protection attributes, but it does not correspond to the optical fiber. One fiber may correspond to multiple TE links.
- B. The TE link is flooded to the entire network by the LMP protocol. Each intelligent network element saves the TE link information of the entire network.
- C. The intelligent network element sends its own bandwidth and other information to other intelligent peers in the network through the LSA in the form of a trace. Provide teaching support for routing and planning.
- D. The verification of the TE link occurs before the control channel is established between adjacent nodes.
Answer: B,D
NEW QUESTION 118
Which of the following is the incorrect description of the internal port properties of the Ethernet board?
- A. For the ingress port of the Tag Aware attribute, if the input data does not carry the VLAN ID, discard.
- B. For the inbound port of the Tag Aware attribute, if the input data carries the VLAN ID, transparently receive the data.
- C. For the ingress port of the Access attribute, if the input data does not carry the VLAN ID, it is directly transparent.
- D. For the ingress port for the Access attribute, if the input data carries the VLAN ID, discard.
Answer: C
NEW QUESTION 119
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
