  B. Regularly evaluate and analyze performance trends to proactively prevent performance degradation and performance failures
  C. Comprehensive professional platform and expert experience, quickly locate the root causes of failures such as slow application and application interruption, and solidify management and prevention methods
  D. Combined with the application development requirements, network optimization is carried out to ensure the benign development of the service

  ---

  Explanation

  Performance management helps customers by observing network and application behavior in real time, analyzing trends before degradation becomes failure, using expert tools to find causes of slowness or interruption, and optimizing the network as services evolve.

• Question 152:

  What are the benefits of IP network planning and design services for customers? (Multiple choice)

  A. Based on the customer's business/application development goals, the elasticity, flexibility ratio and reliability of the target network architecture are constructed to improve the operation efficiency of theenterprise
  B. Provide a long-term evolution roadmap for the customer network to achieve "rational planning and successful implementation"
  C. Through the rational planning, design and implementation of the customer's target network, effectively control the customer network life cycle
  D. Ensure that the customer's business is efficient
  A. Based on the customer's business/application development goals, the elasticity, flexibility ratio and reliability of the target network architecture are constructed to improve the operation efficiency of theenterprise
  B. Provide a long-term evolution roadmap for the customer network to achieve "rational planning and successful implementation"
  C. Through the rational planning, design and implementation of the customer's target network, effectively control the customer network life cycle

  ---

  Explanation

  IP network planning and design benefits include building a target architecture around business goals, giving the customer a long-term evolution roadmap, and controlling the network life cycle through planned design and implementation. Simply saying the business is efficient is too broad to be a distinct planning benefit.

• Question 153:

  What should a presales team use IP network planning and design to help a growing campus do? Choose two.

  A. Shape a future network structure around business growth and resilience
  B. Replacing spare parts logistics with student certification exams
  C. Define an evolution path that supports later implementation
  D. Treat target design as unrelated to customer applications
  A. Shape a future network structure around business growth and resilience
  C. Define an evolution path that supports later implementation

  ---

  Explanation

  IP network planning and design is used to shape the target architecture before implementation. It should align future structure with business growth and resilience, then define an evolution path that can guide later rollout work.

• Question 154:

  How many years is the validity period of Huawei's junior engineer and senior engineer certificate?

  A. 1
  B. 2
  C. 3
  D. 4
  C. 3

  ---

  Explanation

  Huawei's junior engineer and senior engineer certificates use a 3-year validity period. The one-, two-, and four-year values do not match the stated certification cycle for those certificate levels.

• Question 155:

  Huawei is a founding member of Uptime Asia Pacific.

  A. True
  B. False
  A. True

  ---

  Explanation

  The statement checks Huawei's membership role in Uptime Asia Pacific. Since Huawei is treated here as a founding member, marking the statement true matches the fact being tested.

• Question 156:

  For Huawei's network evaluation and optimization service process, which of the following is the correct service process?

  A. Live network data collection--- live network configuration restoration--- target network design ---implementation plan development--- optimization operation implementation --- acceptance test
  B. Target network design --- live network data collection --- live network configurationrestore--- implementation plan development--- optimization operation implementation --- acceptance test
  C. The design of the target network network --- the data collection --- the live network is --- the development of the implementation scheme --- the implementation of the live network configuration restoration --- the optimization of the operation Acceptance testing try
  D. Live network data collection--- live network configuration and restoration --- implementation plan development--- target network design --- optimized operation implementation Acceptance testing try
  A. Live network data collection--- live network configuration restoration--- target network design ---implementation plan development--- optimization operation implementation --- acceptance test

  ---

  Explanation

  The evaluation and optimization flow starts by understanding the existing live network. After data collection, the current configuration is restored for analysis, then the target network is designed, an implementation plan is prepared, optimization is executed, and acceptance testing confirms the result.

• Question 157:

  What is the name of Huawei's SNS service solution?

  A. Software Subscriptions & Assurance
  B. Software Support & Services
  C. Service & Support
  D. Software Services
  A. Software Subscriptions & Assurance

  ---

  Explanation

  SNS expands to a software subscription and assurance service name in Huawei's service portfolio. Software Subscriptions & Assurance matches that meaning directly, while the other names are broader support phrases that do not express the subscription-and-assurance service solution.

• Question 158:

  which migration method below can achieve better smooth migration, but also cover more application scenarios, the main limitation is that there are more compatibility problems, you need to do detailed compatibility testing () before migration

  A. Migration based on application software features
  B. Migration based on volume management software features
  C. Host-based migration
  D. Network-based migration
  C. Host-based migration

  ---

  Explanation

  Host-based migration gives smoother cutover options and can support a broad range of application scenarios because migration logic runs at the host layer. Its tradeoff is compatibility: host software, operating systems, volumes, and applications must be checked carefully before migration.

• Question 159:

  active disaster recovery solution for the FC disaster recovery link must use wavelength division equipment distance is ().

  A. 10 km
  B. 15 km
  C. 20 km
  D. 25 km
  D. 25 km

  ---

  Explanation

  For an active disaster recovery FC link, wavelength division equipment is required at the 25 km distance point. The shorter distances listed do not match the specified requirement for using wavelength division in this case.

• Question 160:

  What are the following SDH network optimizations? (Multiple choice)

  A. Network topology changes
  B. Business path optimization
  C. ECC subnet optimization
  D. Network clock synchronization optimization
  E. Single board replacement optimization
  A. Network topology changes
  B. Business path optimization
  C. ECC subnet optimization
  D. Network clock synchronization optimization

  ---

  Explanation

  SDH optimization can involve changing the network topology, improving service paths, optimizing ECC subnet communication, and correcting clock synchronization. Replacing a single board is a maintenance action, not a network-level optimization category.
