NO.91 What does the component of the ASON network not include?
- A. SC
- B. Intelligent network element
- C. TE link
- D. ASON domain
NO.92 Customer Example 1+1 protect when using different routes, the same wavelength cannot be used for the working wavelength and the guard wavelength.
- A. TRUE
- B. FALSE
NO.93 Which of the following description of ODUk ring protection is wrong?
- A. ODUk ring network protection is mainly applied to the ring network configuration of distributed services. It protects multiple distributed services between all sites by occupying two different ODUk channels.
- B. The agreement must be completed after the protection configuration of each site on the ring network is completed.
- C. Enhanced ODUk ring network protection, no need to set up management nodes. If the management node is set, there is no impact on protection.
- D. Ordinary ODUk ring network protection does not require setting a management node.
NO.94 Which particles can be cross-scheduled for the cross-board of the OSN 8800 device? (Multiple choice)
- A. OPU2
- B. ODU2
- C. ODUflex
- D. ODUO
NO.95 When the NNI port attribute is configured on the same subnet, the IP addresses of the ports on different links can be duplicated.
- A. TRUE
- B. FALSE
NO.96 Which of the following ROADM boards have WSS optical modules? (Multiple Choice)
- A. WSMD9
- B. WSD9
- C. WSM9
- D. RDU9
NO.97 Which of the following description of the performance parameters of line fiber quality monitoring is wrong?
- A. Increasing the pulse width increases the duration of the laser emission, which increases the energy injected, allowing for a larger dynamic range, but an increase in pulse width results in a larger dead zone.
- B. The total loss of the fiber will affect the actual detection distance. The dynamic range of the same detection mode is fixed. The larger the total loss of the fiber, the smaller the distance that can be detected.
- C. Different modes of light pulse width are different in detection, pulse width affects distance accuracy and monitoring distance. The larger the pulse width, the larger the dynamic range, the longer the test distance and the higher the range measurement accuracy.
- D. Line fiber quality monitoring function increases the monitoring accuracy by adding the averaged results to the average. The actual time required from the start detection to the software returning the test result will be greater than the "detection time" is set.
NO.98 The optical and electronic shelves of the OSN 9800 are connected through the master-slave subrack cascading mode and connected through the GE 1/2 port on the CTu board.
- A. TRUE
- B. FALSE
NO.99 Which of the following description of the PM_BIP8 related alarm is correct?
- A. The PM_BIP8_DEG alarm indicates the PM segment signal degradation alarm in the ODU layer.
- B. The PM_BIP8_SD alarm indicates the PM segment signal degradation alarm in the OTU layer.
- C. The PM_BIP8_OVER alarm indicates that PM error amount has exceeded in the ODU layer.
NO.100 The 40 Gbit/s and 100 Git/s coherent systems do not require dispersion compensation because the coherent board has a large dispersion tolerance. NG WDM does not support noncoherent networks and coherent networks for hybrid transmission.
- A. TRUE
- B. FALSE
NO.101 What are the basic principles of MSTP device fault location? (Multiple choice)
- A. Network first, then network element
- B. Advanced first, then low level
- C. Low speed first, then high speed
- D. External first, then transfer
NO.102 Which of the following paths can be configured on the network management? (Multiple Choice)
- A. Client
- B. ODUk
- C. OTS
- D. OCh
NO.103 Which of the following protections need to use the APS protocol? (Multiple Choice)
- A. ODUk ring network protection
- B. SW SNCP protection
- C. 1:1 optical line protection
- D. ODUk SNCP protection
NO.104 Which of the following is not included in an ASON network?
- A. TE Link
- B. SC
- C. ASON Domain
- D. ASON NE
NO.105 The following limitations of alarm and performance analysis methods are: (Multiple Choice)
- A. Field maintenance personnel cannot understand the current health of the equipment.
- B. The network administrator cannot obtain any alarms, time, and historical alarms of the device.
- C. When some faults occur, there may be no obvious alarms or performance events reported, and sometimes no alarms or performance events are found.
- D. In the case of complex networking, service, and fault information, many alarms and performance events may occur along with the occurrence of faults. Due to too many reports and performance events, maintenance personnel are unable to analyze.
