List of questions

Question 1

(0)

In the case of MSP, you need to set the MSP protocol ID of each NE. To ensure that each ID is unique, you are advised to set the MSP protocol ID to the same value as the NE ID.

Question 2

(0)

In the frame structure of SDH signals, there are abundant overhead bytes used for operation, administration, and maintenance (OAM). The overhead bytes account for ( ) of all bits in the entire frame

Question 3

(0)

Which of the following bridges is used to forward data based on the MAC address and VLAN ID carried in data?

Question 4

(0)

In the 2.5G MSP ring consisting of four MSTP sites, when a protection switching occurs, which of the following statements about the alarm reporting is correct?

Question 5

(0)

Which of following are the configuration modes of new NEs? (Multiple Choice)

Question 6

(0)

MSP is a network-level protection scheme. The MSP does not directly protect a service, and the MSP switching and restoration are not affected even if there is no service on the MSP ring.

Question 7

(0)

Which of the following is the frame structure of STM-16?

Question 8

(0)

Optical fiber loss includes the bending loss, absorption loss, and scattering loss.

Question 9

(0)

The pointer is used for alignment and indicates the start position of VC-n in the corresponding AU or TU frame. In this way, the receive end can correctly remove the corresponding VC from the STM-N,

Question 10

(0)

During service configuration, there are two timeslot modes. Huawei uses the interleaved timeslot mode by default.

Question 50 - H31-311 discussion

If the overhead bytes pass through the backplane bus between two slots, the two slots are called paired slots. Paired slots implement automatic transparent transmission of overhead bytes, such as (),(), and (). This improves MSP switching performance and protects DCC communication with other NEs even if the SCC board on the local NE is offline. (Multiple Choice)
