Huawei Certified Internetwork Expert-Transmission Sample Questions:
Question #1
PW APS bundling can reduce APS resource consumption and increase the speed of batch service switching.
Which of the following descriptions about PW APS bundling are correct? (multiple choice)
- A. When the PW APS protection group is switched, its subsidiary protection pairs will not undergo the same switching.
- B. When the status of the PW APS slave protection pair changes, it will not cause the status of the PW APS protection group to change.
- C. When the PW APS protection group is switched, its subsidiary protection pair also undergoes the same switching.
- D. When the status of the PW APS slave protection pair changes, it will cause the status of the PW APS protection group to change.
Correct Answer: B,C 🗳️
Question #2
If a ROADM site adopts WSS+RMU configuration, which of the following influences on SOM is wrong ()?
- A. There is a local optical amplifier but no filter, the full-wave noise of the local optical amplifier affects the OSNR of the wavelength in the pass-through direction
- B. If the local RMU is used to add waves and has an optical amplifier, the OSNR value of the wavelength in the pass-through direction detected by SOM will deviate from the actual value
- C. The source and sink optical amplifiers of the optical crossover at this site must be in the same network element
Correct Answer: B 🗳️
Question #3
Data collection is very important for on-site maintenance engineers. It can not only understand and deal with faults well, but also provide a basis for future processing. What information needs to be collected when EMS/EFS/EGS panels are used for data collection? (multiple choice)
- A. EPL/EPLn business issues require feedback data such as the number of VCTRUNK, etc.
- B. Special configuration issues require feedback data such as Qos, etc.
- C. Public basic data such as version and other basic information that require feedback
- D. EVPL/EVPLn business issues require feedback data, such as test frame feedback information, etc.
Correct Answer: A,B,C,D 🗳️
Question #4

Correct Answer: A 🗳️
Question #5
When planning a 1+1 HSB, the corresponding planning principles should be followed. Which of the following are not HSB planning principles?
- A. It is recommended to set the "Alarm reporting method" to "Report only to the protection group"
- B. If the recovery type is selected as the protection type, it is recommended to set the waiting recovery time within the range of 5-12 minutes, and it is recommended to set the default value of 10 minutes
- C. Although 1+1 HSB does not limit the slot of the IF board, it is still recommended that the main/backup IF board be installed in the dual slot
- D. It is recommended to enable reverse switching to prevent the sender from performing invalid RDI switching due to signal fading
Correct Answer: D 🗳️
