NO.52 The service types supported by the PND2 board used by the OSN 8800 are: (Multiple choice)

VPWS

EPL

VPLS

EPLAN

NO.53 The following description of 1+1 and 1:1 optical line protection, the fault is (). (Multiple Choice)

1:1 optical line protection switching mode can only be double-ended switching

The main difference between 1:1 optical line protection and 1+1 optical line protection is whether the APS protocol is required.

1+1 optical line protection and 1:1 optical line protection use the same protection board

According to different placement of OLP boards in the network, 1+1 optical line protection can be divided into 1+1 OMS path protection and 1+1 OTS path protection.

NO.54 Which of the following is the incorrect description of the internal port properties of the Ethernet board?

For the ingress port for the Access attribute, if the input data carries the VLAN ID, discard.

For the inbound port of the Tag Aware attribute, if the input data carries the VLAN ID, transparently receive the data.

For the ingress port of the Access attribute, if the input data does not carry the VLAN ID, it is directly transparent.

For the ingress port of the Tag Aware attribute, if the input data does not carry the VLAN ID, discard.

NO.55 In the Colored&Directioned scenario of the 4D ROADM, if you want to implement local service scheduling in four directions, how many sets of M40V+D40 are needed?

NO.56 What should I pay attention to when commissioning a 100G and 10G hybrid transmission system? (Multiple Choice)

Pay attention to the mixed spectrum. The spectrum of the 100G signal is wider and looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent.

For a hybrid transmission system with dispersion compensation, the dispersion compensation requirements are consistent with the requirements in a 10G non-coherent system.

In order to accurately measure the optical power of 100G wavelength, it must be debugged using a spectrum analyzer or a MAC card.

The optical power of the 100G signal is recommended to be higher than the optical power of the 10G signal, but not higher than the single-wave nominal value of the optical panel.

NO.57 Which of the following is not a part of the ASON Control Protocol?

LMP

RSVP-TE

IS-IS

OSPF-TE

NO.58 The following description of the connection of the NG WDM device to the network management computer, which is wrong?

The connection network management computer can be connected either directly or through a local area network, as the case may be.

If the subrack connection mode is master-slave mode, the network management computer must be connected to the main subrack.

All network element IP addresses must be in the same address segment as the network management computer IP address.

Only the gateway network element needs to be connected to the network management computer.

NO.59 The following description of the operation of the device, the error is:

Wear an ESD-preventive wrist strap or gloves to prevent static electricity from damaging the board.

CLASS 1M means low optical power, no damage to eyes or skin

Regularly clean the air filter to facilitate heat dissipation

Equipment needs safety grounding

NO.60 Which of the following is the incorrect description of the internal port properties of the Ethernet board?

For the ingress port for the Access attribute, if the input data carries the VLAN ID, discard.

For the inbound port of the Tag Aware attribute, if the input data carries the VLAN ID, transparently receive the data.

For the ingress port of the Access attribute, if the input data does not carry the VLAN ID, it is directly transparent.

For the ingress port of the Tag Aware attribute, if the input data does not carry the VLAN ID, discard.

NO.61 The shortcomings of traditional OTDR meters in measuring optical fibers are: (Multiple choice)

Manual interpretation is required, which requires high operator requirements

Need inbound measurement

Cannot be used for routine maintenance testing

Business will be interrupted during measurement

NO.62 Which of the following SOM systems is not monitored?

Main light path performance

Type of originating FEC

Light performance flatness

Receive OTU input optical power

NO.63 Before querying the error and optical power on the network management, you need to perform the () operation. Otherwise, you cannot query the corresponding teaching data.

Create a logical fiber

Configuration data

Synchronizing network metadata

Turn on NE performance monitoring time.

NO.64 When the working channel protected by the optical line fails, it cannot be automatically switched to the protection channel. What are the possible reasons? (Multiple Choice)

Protection group parameter configuration error

Artificially issued a lock command

Waiting for the recovery time to be set too long

The protection channel is faulty

NO.65 During the configuration of the E-LAN, the “MAC Address Learning Mode” can be set to SVL and IVL. SVL is a stand-alone VLAN learning, and IVL is a shared VLAN learning.

TRUE

FALSE

NO.66 When the board detects that the error rate of the regenerator section signal exceeds 10 by detecting the B1 byte, the B1_SD alarm is reported.

TRUE

FALSE

NO.67 The OTS path refers to the physical fiber connection between two adjacent OM/OD/OA on the main optical path.

TRUE

FALSE

NO.68 The following description of the cross-board of the OSN 8800 T64 subrack. Which is correct? (Multiple choice)

XCT+SXM can support ODU0, 1, 2, and 3 levels of crossover.

XCT+SXM can be used together to provide an ODUK crossover with a total capacity of 2.56 Tbit/s.

XCT+SXM can be regarded as a whole when working. If any faulty, the two boards will be switched together.

Enhanced subrack can only be configured with UXCT+USXM or UXCT+USXH

NO.69 MPLS APS is a network protection mechanism that implements service creation through the detection function of MPLS OAM.

TRUE

FALSE

NO.70 Which of the following description of the Optix OSN 9800 sub-rack is correct? (Multiple choice)

When the OSN 9800 Universal Platform Sub-rack is used as a slave sub-rack, the main control board must be placed.

The OSN 9800 U16 sub-rack has a total of 16 service slots. These slots have the same capacity and support up to 400 bit/s ODUk crossover in a single slot.

In the OSN 980 0U32 sub-rack, IU70 is the primary CTU and IU78 is the standby CTU.

The service board can be inserted into the IU18 slot only when the OSN 9800 P18 is used as the slave sub-rack.

NO.71 Which of the following description of ODUk ring protection is wrong?

ODUk ring network protection is mainly applied to the ring network configuration of distributed services. It protects multiple distributed services between all sites by occupying two different ODUk channels.
