H31-321 Online Practice Questions and Answers

A ring is configured with STM-64 two-fiber bidirectional MSP. The port rate of the ring is 10 Gbit/s.

A. TRUE

B. FALSE

When the NEs of a Huawei network are connected to third-party/external equipment you can create virtual NEs that are mapped to the third-party/externa I equipment and then create cross-subnet trails between Huawei NEs and virtual NEs. In this manner, discrete services can be prevented.

A. TRUE

B. FALSE

Which of the following are false about TE links?

A. TE links are flooded to the entire network through the LMP protocol, so each ASON NE can learn about network-wide TE link information.

B. An ASON NE floods its information (such as bandwidth) on TE links to the entire network through LSA, to provide data support for route calculation.

C. A TE link, like a fiber, is a type of network resource and has bandwidth and protection attributes. A fiber may correspond to several TE links.

D. TE links are verified before the control channel between two adjacent nodes is established.

Which of the following about the SSM protocol are true?

A. After the SSM protocol is disabled, the clock network can be unidirectional but cannot adopt a ring

B. topology.

C. After the standard SSM protocol is enabled, the clock network can be bidirectional but cannot adopt a ring topology.

D. After the extended SSM protocol is enabled, the clock network can be bidirectional and adopt a ring topology, which can be intersecting or tangent with other networks.

E. The SSM protocol has little to do with clock networks.

An NE is frequently unreachable to the NMS. Which of the following are possible causes?

A. Conflicted NE IDs or IP addresses

B. The network size is too large, and ECC communication is beyond the processing capability of the network.

C. On the network, multiple users are attempting to log in to the NE.

D. The cross-connect board is faulty.

E. The SCC board is faulty.

Which of the following may cause generation of discrete services in an NG-SDH system?

A. Trail query conditions are not met. For example, the fiber connections created on the NMS are inconsistent with the actual fiber connections.

B. Trail query restrictions exist. For example, among the multiple sources and sinks of a VC-4 service trail,

C. some are outbound optical ports, and the others are non-outbound optical or electrical ports.

D. Cross-connection configurations are incomplete or incorrect. Outgoing services exist.

E. The service trails created in an end-to-end manner is not activated on the NMS.

Generally, a central NE where ECC communication load is heavy and congestion is the most likely to occur is set as the gateway NE.

A. TRUE

B. FALSE

You need to plan the MS when gold services exist on an ASON network. Which of the following are true about MS planning?

A. If only a few gold services exist, upgrade the gold services to diamond services.

B. The MS should cover all nodes on which gold services are required to be configured. Multiple MSs can be used to cover more nodes on a complex network.

C. If the gold services take up less than half of the optical path resources, set part of the MS for the gold services, in other words, only part of the VC-4 resources on the MS are allocated for the gold services.

D. Services should be evenly distributed in an MS. Avoid high bandwidth utilization in certain portion of an MS but low bandwidth utilization in other portion of the MS.

What are the procedures of handling discrete services on the NMS?

A. Check the consistency between NMS data and NE data.

B. Check the consistency between the fiber connections created on the NE and physical fiber connections.

C. Search for protection subnets, and ensure that all protection subnets are searched out and properly configured.

D. After discrete services are searched out, the NMS analyzes the discrete services based on the displayed causes and solutions.

E. After discrete services are searched out, delete the discrete services on the NMS.

Which of the following are true about the relationship between ASON software, board software, NE software, and NMS software?

A. ASON software is independent from board software, NE software, and NMS software.

B. NE software runs on a system control board.

C. All boards run ASON software and board software.

D. An NM computer runs NMS software
