(Multiple Choice)  The network element broadcasts the clock quality information of the synchronization source to the downlink site through the s1 byte. And reverse notice the uplink site by the S1 byte in the direction of the synchronization source that the clock quality from the local network element is “not available for synchronization”.  If there are multiple clock sources with the highest quality level, the network element selects the clock with the highest clock priority as the synchronization source.  According to the clock source priority table, the network element first selects the clock with the highest quality level from the available clock sources as the synchronization source.  The network element broadcasts the clock quality information and the clock source ID of the synchronization source to the downlink site through the S1 byte, and reverse notices the uplink site that the clock quality from the local network element is “not available for synchronization” by the S1 byte in the direction of the synchronization source. QUESTION 78The main function of the transport layer in the Huawei ECC protocol stack is _____.  Establish and maintain a MAC connection between neighboring network elements.  Establish and maintain an ECC routing table.  Provide end-to-end communication services to the upper layer  Provide data communication services. QUESTION 79After the PWE3 service is successfully deployed, what is the deployment status of the PWE3 service displayed?  Deployment  Activated  Deployed  Activation QUESTION 80In the ROADM, which of the following layer of OTN paths do not need to be manually configured, it can be obtained directly by path search? (Multiple Choice)  OTS  OSC  OMS  OCh QUESTION 81Which of the following device types support the master-slave sub-architecture mode? (Multiple Choice)  OSN 8800  OSN 1800V  OSN 9800 QUESTION 82When the working channel of the optical line protection fails, it cannot be automatically switched to the protection channel. What are the possible reasons? (Multiple choice)  The protection channel is faulty  Protection group parameter configuration is error  Artificially issued a lock command  Waiting for the recovery time to be set too long QUESTION 83The steps that must be performed when configuring the Ethernet private line service carried by the PW are as follows: (Multiple Choice)  Configure QoS  Configure MPLS tunnel  Configure port DCN  Configure the UNI port QUESTION 84Which of the following reasons does not cause optical power anomalies?  Enable FEC function  Pigtail connection error  Equipment temperature is too high  The pigtail is too large QUESTION 85When configuring the Ethernet Layer 2 attribute, set the Default VLAN ID and VLAN Priority of the untagged frame when the TAG ID is set to Accese or Hybrid. The “VLAN priority” is set according to the QoS of the unified plan.  TRUE  FALSE QUESTION 86Which of the following statements about the Service Package is incorrect?  The Service Package can configure the working mode, service type, cross-connection, and port type in batches.  Currently, Service Package is available to the TOA, TOX and TSC boards.  You can configure service packages in two modes. One is to configure boards in batches, and the other is to configure each board.  Service package enables one-click configuration of typical services by issuing multiple configuration commands in batches, facilitating product deployment commissioning and reducing maintenance costs. QUESTION 87In the WDM system, what is the reason for the fiber attenuation and bit error rate? (Multiple Choice)  Fiber bending  Fiber damage  Fiber break  Fiber aging QUESTION 88For emergency handling of business interruptions, fault location should be performed as soon as possible, and then the business should be resumed.  TRUE  FALSE QUESTION 89Which of the following is not a part of the ASON Control Protocol?  LMP  RSVP-TE  IS-IS  OSPF-TE QUESTION 90The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the “IN” optical port. The RDU (ROADM Demix Unit) optical module broadcasts nine identical optical signals, which are output from the “DM1~DM8” and “ECPO” optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the “EXPI” optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the “AM1″~”AM8” optical port.  TRUE  FALSE QUESTION 91The 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 QUESTION 92In WDM systems, when using less than () wavelength, it is ideal to use a dielectric thin film filter (TFF).  4  8  16  20 QUESTION 93MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.  True  False QUESTION 94A, C are the WDM OTM stations, and B is the relay station. When the transmission direction of the A to B stations is interrupted, the Wavelength side of the B-stack OTU relay board reports the R_LOS emergency alarm and runs the processing to the upstream A.The station side OTU2_BDI secondary alarm. At the same time, the alarm continues to be transmitted to the downstream station of the B station. After the alarm is processed at the C site, the ODU2_PM_AIS minor alarm is reported on the WDM side of the C-site OTU, and the ODU2_PM_BDI secondary alarm is transmitted back to the upstream station A.  TRUE  FALSE QUESTION 95Which of the following is not a precaution after board replacement?  Record the settings of jumpers and DIP switches on the board.  Check the indicator blinking status of the board and ensure that the board works properly.  Ensure that no abnormal alarm.  /For functional units that have backups, check whether the switchover is normal. QUESTION 96The optical and electronic shelves of the OSN 9800 are connected through the master-slave subrack cascading mode and connected through the GE 1/2 port on the CTu board.  TRUE  FALSE QUESTION 97Which of the following statements about the modulation technologies of the 40Gbit/s and 100Gbit/s coherent systems are correct?  The modulation technology used in a 40G coherent system is ePDM-QPSK.  The modulation technology used in a 100G coherent system is ePDM-QPSK.  The modulation technology used in a 100G coherent system is ePDM-BPSK.  The modulation technology used in a 40G coherent system is ePDM-BPSK.  Loading … Pass Huawei H31-341-ENU Actual Free Exam Q&As Updated Dump: https://www.dumpsmaterials.com/H31-341-ENU-real-torrent.html --------------------------------------------------- Images: https://exams.dumpsmaterials.com/wp-content/plugins/watu/loading.gif https://exams.dumpsmaterials.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-10-26 15:07:34 Post date GMT: 2022-10-26 15:07:34 Post modified date: 2022-10-26 15:07:34 Post modified date GMT: 2022-10-26 15:07:34
