Huawei HCIP-Transmission V2.0 認定 H31-341-ENU 試験問題:

1. For emergency handling of business interruptions, fault location should be performed as soon as possible, and then the business should be resumed.

A) TRUE
B) FALSE

2. The E&M signal defines the type of connection between a relay device and a signaling unit. Which of the following belongs to the relay device?

A) Softswitch platform
B) E&M voice exchange
C) PBX
D) Telecommunications Exchange

3. Which of the following description of the single station commissioning is wrong?

A) It is strictly forbidden to plug and unplug the power plug and PIU board.
B) In case of power failure, the contact board can be used without anti-static wrist or anti-static gloves.
C) Single station hardware check is complete, make sure all power switches are in the off position
D) If the input voltage of the equipment is not within the required range, suggestions for rectification should be proposed.

4. VPLS (Virtual Private LAN Service) is a Layer 2 VP technology that simulates a local area network.

A) TRUE
B) FALSE

5. Which of the following description of the performance parameters of line fiber quality monitoring is wrong?

A) 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.
B) 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.
C) 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.
D) 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.
