NO.101 When LMSP is configured, there are two switching modes: single-ended switching and dual-ended switching. The protection protocol does not need to be enabled for single-ended switching.

TRUE

FALSE

NO.102 Which of the following statements about the optical-layer interfaces OTM-n.m and OTM-nr.m of OTN is incorrect?

n indicates the number of wavelengths carried by the maximum capacity.

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

r indicates OTM without the OSC function.

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

NO.103 When setting the LCAS mode, follow the following principles:
1. If devices at the two ends are both Huawei devices, set them to the “Standard Mode”.
2. If a Huawei device is interconnected with a third-party device, set the interconnected devices to the same mode according to the mode supported by the third-party device.

TRUE

FALSE

NO.104 Which of the following bytes in the regenerator section overhead are associated with R-OOF and R-LOF?
(Multiple Choice)

NO.105 A two-fiber ring topology consisting of three NEs is arranged in the counterclockwise sequence as A, B, and
C. Services between A and C occupy the 48th VC-12 timeslot in the first VC-4 on the short path, and services between B and C also occupy the 48th VC-12 timeslot in the first VC-4 on the short path. In this case, which of the following is the subnet type of the ring protection?

Unidirectional path protection ring

SNCP ring

Bidirectional MSP ring r

All of the above

NO.106 Which of the following statements about OTN advantages is incorrect?

The WDM function is used to meet the requirement for Tbit/s bandwidth per fiber.

OTN provides a maximum of five levels of nested or overlapped TCM connection monitoring.

OTN provides powerful outband FEC functions to effectively guarantee the line transmission performance.

OTN provides 2.7 Gbit/s, 10.7 Gbit/s, 43 Gbit/s, and even 111.8 Gbit/s high-rate interfaces.

NO.107 The rates of the SF64 and SL64 boards are both STM-64. Therefore, the two boards can be interconnected.

TRUE

FALSE

NO.108 Which of the following statements about overhead bytes is incorrect?

A1 and A2 are framing bytes. These bytes are used to separate STM-1 frames in a signal flow.

J0 is a regenerator section trace byte. This byte is used to repeatedly transmit a section access point identifier, so that the receive end can verify its continuous connection to the specified transmit end.

B1 is bit interleaved parity-8 (BIP-8). This byte is used to monitor bit errors at the regenerator section layer.

E1 and E2 are orderwire bytes. These bytes are used to provide a voice channel for orderwire connections.

NO.109 Which of the following clock working modes support the ITU-T G.781 standard? (Multiple Choice)

Tracing

Holdover

Free-run

Master/Slave

NO.110 Frame-Mapped GFP (GFP-F) is a processing mode oriented to data coding blocks (such as Fiber Channel and ESCON).

TRUE

FALSE

NO.111 Which of the following is the meaning of SFD in the Ethernet frame structure?

Preamble

Frame check sequence

Start frame delimiter

Payload

NO.112 In the SDH optical synchronous transmission system, which of the following bytes is used to transmit the quality and usage information of clock sources?

NO.113 When a fiber cut test is performed on a normal MSP ring, which of the following alarms is reported?
(Multiple Choice)

TU-AIS

R-LOS

APSJNDI

BD STATUS

NO.114 PDM uses the polarization beam splitter to divide the laser into two perpendicular directions: x and y.

TRUE

FALSE

NO.115 A 1510 nm optical supervisory channel can be effectively amplified after it passes an EDFA.

TRUE

FALSE

NO.116 When severely errored seconds (SESs) are present in the PM section at the ODUk layer, which of the following alarms is reported on the NMS?

ODUk_PM_ES

ODUk_PM_SES

ODUk_PM_SESR

ODUk _PM _UAS

NO.117 The value of the MFAS byte increases with the sequence number of the OTUk/ODUk base frame, and a maximum of ( ) base frames are included.

128

256

512

NO.118 The working mode of a port determines the flow control mode of the port. When the working mode is 100 Mbit/s full duplex, which of the following flow control modes can be used?

Auto-negotiation flow control mode

Non-auto-negotiation flow control mode

Both of the above

None of the above

NO.119 When multiple users need to share the same VCTRUNK and use the same VLAN ID, the QinQ technology can be used.

TRUE

FALSE

NO.120 OTM nr.m consists of a maximum of “n” optical multiplexing channels and does not support non-channel-associated overheads. The letter “r” indicates function reduction.

TRUE

FALSE

NO.121 A PAUSE frame uses a reserved multicast address and is not forwarded by a bridge or switch, In this way, the PAUSE frame does not generate any additional information.

TRUE

FALSE

NO.122 Which of the following alarm/event dumping modes are supported by the U2000? (Multiple Choice)

Manual dumping

Automatic dumping

Overflow dumping

Periodic dumping of alarm logs

NO.123 Which of the following overhead bytes needs to be processed at an electrical regeneration site?

All of the above

TCM
