NO.29 Which of the following is the main advantage of SDH? (Multiple choice).

standard interface.

Synchronous multiplexing.

Powerful OAM

High compatibility.

NO.30 The number of ODU2e signals multiplexed into the ODU3 signal is the same as the number of ODU2 signals multiplexed into the ODU3 signal

yes

False

NO.31 Which of the following methods can be used to multiplex low-order ODUK to higher-order ODUk?

Time-division multiplexing

Wavelength division multiplexing

Null division multiplexing

Frequency division multiplexing

NO.32 Both PDH and SDH have globally harmonized standards.

True

False

NO.33 Which of the following logic function blocks are involved in processing clock signals? (Multiple choice).

SPl

RST

MCF

SETS

NO.34 For alignment; Indicates the starting position of VC-n in the corresponding AU or TU frame. * This way: The receiver can correctly remove the corresponding VC from STM-N, and then The VC and C packages are separated into separate low-rate signals, such as PDH, which means that the low-rate path signal can be dropped directly from the STM-N signal.

True

Error

NO.35 Which of the following statements about the OTM-n .m and OTMnr .m for OTN are incorrect?

n represents the number of wavelengths carried by the maximum capacity

m indicates the rate. The value can be 1, 2, or 3. .

r represents OTM., which does not have OSC capabilities

OTM-nr .m with OSC signal is OTM-n.m.

NO.36 Which of the following is affected by changing the element ID of OSN3500 on NMS?

Interruption of business.

Restart your device.

Network element communication is interrupted.

NE time is out of sync.

NO.37 The TAG attribute cannot be set for the internal port VCTRUNK of the single board on the NMS.

True

False

NO.38 In WDM systems, it is ideal to use a dielectric thin film filter (TFF) when using less than () wavelengths.

NO.39 During service configuration, there are two time slot modes. Huawei uses interleaved time slot mode by default.

True

False

NO.40 In the system control unit, which of the following databases does not lose data after a power failure? (Multiple choice).

MDE

DRDB

FDB0

FDB1

NO.41 Which of the following is the steps to multiplex a low-speed service into a high-speed SDH service? (Multiple choice).

Mapping

Overhead insertion

Alignment

Multiplexing

NO.42 The device IP address of the gateway element and the non-gateway element must be set in the same network segment.

True

Error

NO.43 Which of the following statements regarding the protection of the cross-connecting plate 1+1 is correct? (Multiple choice).

The source business board sends services to the main and standby crossover boards. .

After the service cross-connection is completed, the active and standby cross-board sends the data of the primary cross-board to the receiving service board.

The receiving service board can only receive data from the active cross-link board

The bus of the two cross-connected modules works independently and does not interfere with each other. .

Dual bus system structure indicates that the service board performs dual data transfer to the cross-connection side and selectively receives data on the cross-connection side. .

Both cross-connecting plates have the same configuration. The service board will selectively receive services from one of them based on the quality of service and the status of the cross-connecting board. .

NO.44 When using the LCAS function, which of the following overhead bytes is used to transmit control information? (Multiple Choices)

NO.45 Which of the following ITLI-T recommendations define the OTN frame structure?

G.694

G.652

G.975

G.709

NO.46 EPL services use bandwidth exclusively on the line, which is very safe. Dedicated line applications for VIP customers

True

Error

NO.47 The following is the frame structure of the STM-16?

9*270*1

9*270″4

9*270*16

9*270*64

NO.48 Which of the following is not an EVPLAN feature?

bandwidth sharing

Forwarding based on MAC address

point-to-point, and point-to-multipoint topologies

Multipoint to multipoint topology

NO.49 The OTN signal has a fixed pad period, the same frame period as the SDH signal.

True

False

NO.50 Which of the following statements about the EFS4 board are correct? (Multiple choice).

The board has four FE ports. .

The board supports three layers of text exchange. .

The plate must be used with the processing plate.

The board interface is the LC interface.
