New H31-311_V2.5 Test Materials & Valid H31-311_V2.5 Test Engine [Q79-Q100]

NO.79 In the case of SNCP, the board selectively receives the service. Therefore, SNCP can protect services on the line.

NO.80 When the ACT indicator of the SDH board is off, it means that the board has a hardware failure and cannot be used.

NO.81 The dual fiber ring topology consisting of three network elements is arranged in counterclockwise order as the service between A, B and C A and C occupies the first VC-48 on the short path VC-12 time slots, B and C of the same service also occupy the 48th of the first VC-4 on the short path VC-12 time slots

NO.82 The STAT indicator of the SDH board flashes red, lights up for 100ms, and turns off for 100ms. Which of the following means the state of the metric?

NO.83 The value of the MFAS byte increases with the sequence number of the OTUk/ODUK base frame and includes the most () base frames.

NO.84 EPL services use bandwidth exclusively on the line, which is very safe. Dedicated line applications for VIP customers

NO.85 Which of the following is not a nonlinear effect?

NO.86 In the Windows operating system, the log files of the U2000 program are stored in the () directory of the U2000 installation disk.

NO.87 Suppose 2 VC-12 time slots need to be bound to the VCTRUNK1 of the N2EFS4 board. When there are 8 VC4 slots on the N2EFS4 board, which of the following slots meets the requirements?

NO.88 In MSP networking, when the optical fiber is connected between sites, the east light plate of the site is connected to the west light plate of the downstream site, and these stations are connected in turn to form a ring. In this case, the direction from the toko plate of the site to the wine light plate of the downstream station is the direction of the main ring, and the direction of forming the ring is the direction of service.

NO.89 Some SNCP protection inversion conditions are default, such as AU-AIS and TU-AIS. Other conditions are optional, such as HP-TIM and HP-SLM. Optional conditions can be flexibly set according to the level of the costume.

NO.90 Which of the following is the frame indicated by the VC-4 J1 byte by the AU pointer of the current frame?

NO.91 WDM transmits optical signals multiplexed at multiple rates (wavelengths) through a single optical fiber, and the digital signals carried by these optical signals must have the same rate and data format

NO.92 The index is used to folio and delineate the starting position of VC-n in the corresponding AU or TU frame so that the receiving end can correctly remove the corresponding VC from the STM-N The VC and C packages are then separated into separate low-rate signals, such as PDH That is; Low-rate branch signals can be discarded directly from the STM-N signal

NO.93 Linear MSP (LMSP) has two modes: 1+1 and 1:1. Additional services can only be configured for the protection channel in 1:1 mode of the LMSP.

NO.94 When using the LCAS function, which of the following overhead bytes is used to transmit control information? (Multiple Choices)

NO.95 When the sender detects that the b6-b8 of the K2 byte is 110, it means that the sender has reported an alarm ().

NO.96 Which of the following statements regarding the sequence of signal flows between the SDH interface and the cross-connecting unit is correct?

NO.97 Which of the following can be used as the central wavelength of the pump source in EDFA? (Multiple choice).

NO.98 Which of the following statements about the OTM-n .m and OTMnr .m for OTN are incorrect?

NO.99 For OSN3500, there is a slot mapping relationship between the processing board and the interface pre-processor. The processing board in slot 1 maps to the interface board in slots 19-20.

NO.100 In Recommendation ITU-T G.692, the allowable channel frequencies are based on the reference frequency (), and the channel spacing can be 100 GHz, 50 GHz or 25 GHz.
