Q36. The mask of an IP subnet is 28 bits, then the number of hosts in the subnet is?

Q37. A common WDM service can be converted into an ODUk SNCP service. However, an ODUk SNCP service will be interrupted when it is converted into a common WDM service.

TRUE

FALSE

A common WDM service can be converted into an ODUk SNCP (Subnetwork Connection Protection) service. However, when an ODUk SNCP service is converted back into a common WDM service, the protection is interrupted, causing service disruption. This is because SNCP provides path-level protection with automatic switching, which is lost during conversion back to a simpler WDM configuration. HCIP- Transmission highlights this limitation in protection mechanisms when migrating between service types, important for network planning and service continuity management.

Q38. Corresponds to the ISO seven-layer model. Ethernet corresponds to the physical layer and network layer of the seven-layer model, and the specifications defined by Ethernet include the MAC sublayer and the physical layer of the data link layer.

True

False

Q41. Which of the following descriptions about the Directioned scene is correct? (Multiple choice)

The wavelength carrying local traffic can be transmitted in a fixed direction.

If the current path needs to be adjusted, it is necessary to enter the station to adjust the fiber connection of the network.

Directioned scenarios are applied to non-ASON networks

When the service needs to be adjusted, or when the working path fails and the protection path is used, the optical cross-connect can be manually configured to realize flexible scheduling of services.

VPwS

EPL

VPLS

EPLAN

Q43. During CV/FFD, the ingress node transmits detection packets at a specific interval, and the egress node checks the number and content of these packets at an interval ( ) times the length of the detection packet transmission interval.

The egress node checks received CV or FFD packets over any 3-second window when the ingress interval is 1 s (i.e., at three times the transmission interval).

Q44. Which of the following functions are mainly performed in the sink function processing of the electrical layer overhead? (Multiple choice)

Realize the suppression of alarms and the reporting of performance events

Back-insert or down-insert signal

Reporting of defect information

Overhead Monitoring at the Receiver

Q45. According to the description in the blank, select the correct on-demand OAM type:

Assignment based on IP address

Q47. Both the SC2 and ST2 boards support the processing and transparent transmission of 1588V2 signals.

True

False

Q48. Which of the following statements about optical multiplexer and demultiplexer boards is false?

TNG2D6001 demultiplexes one multiplexed-wavelength signal into a maximum of 60 even-wavelength optical signals.

TNG2M60V is a 60-channel multiplexer board with VOA (Super C band).

TNG2UM40 is a 40-channel multiplexer board (Super C band).

The UITL board multiplexes and demultiplexes signals with 50 GHz spacing and signals with 100 GHz spacing.

The TNG2M60V board is not a 60-channel multiplexer with VOA for the Super C band; this description is incorrect for that board model.

Q49. Which of the following is the number of VLANs that QINQ technology can provide?

4095*4095

4096*1024

4096

1024*1024

Q50. For the SSM protocol, which of the following statements are correct? (Multiple choice)

When the SSM protocol is not enabled, the clock network can only be configured as unidirectional and cannot form a loop.

When the extended SSM protocol is started, the clock network can be configured as bidirectional and can form a loop.

When the standard SSM protocol is started, the clock network can be configured to be bidirectional, but cannot form a loop

Whether to activate the SSM protocol has little effect on the clock network.

Q51. The maximum output optical power of an OBU of an optical amplifier is 20dBm, how many dBm should the standard output optical power of the single-wavelength system be used in the C-band 80 be?

True

False

Q58. Which of the following descriptions about ROADM is correct? (Multiple choice)

ROADM can adjust the optical power balance of the pass-through and add-wavelength wavelengths

The wavelength adjustment of the ROADM site requires the operation and maintenance personnel to go to the site for support

Q60. Which of the following statements about the TMB1AST2 board are true?

The TM1 optical port must be connected to the TMI1 optical port.

The TMB1AST2 board supports the IEEE 1588v2 clock processing and OTDR functions.

When the board is working with a DFIU03/DFIU04 board, the OSC optical port must be configured with an optical module that supports the 1511 nm wavelength.

When the board is working with a DSFIU01/DSFIU02 board, the TM1/RM1 optical port must be configured with an optical module that supports the 1511 nm wavelength, and the TM2/RM2 optical port must be configured with an optical module that supports the 1491 nm wavelength.

The TMB1AST2 board is a specialized optical module used in transmission equipment. According to HCIP- Transmission references, all the statements about this board are correct. (A) The TM1 optical port must be connected to the TMI1 optical port for proper operation. (B) It supports IEEE 1588v2 clock processing, essential for precise time synchronization, and includes OTDR (Optical Time Domain Reflectometer) functions for fiber fault detection and maintenance. (C) When working with DFIU03/DFIU04 boards, the OSC optical port requires an optical module that supports the 1511 nm wavelength to ensure wavelength compatibility. (D) Similarly, when working with DSFIU01/DSFIU02 boards, the TM1/RM1 and TM2/RM2 ports must use optical modules supporting 1511 nm and 1491 nm wavelengths respectively, ensuring correct wavelength assignment for WDM channels. This detailed configuration ensures interoperability and proper system functionality.
