• Question 131:

  A department's service data system is already running on HUAWEI CLOUD, but users report slow query response times, affecting overall user experience. As a cloud service architect, which of the following actions should you take to resolve this problem? (Choose three)

  A. The best optimization solution varies based on workload type -- use performance data to optimize the selection of resource types and configuration options.
  B. Establish performance and monitoring metrics to capture key indicators, and use visualization tools to identify performance bottlenecks, hot spots, wait states, or low utilization.
  C. Use messaging middleware and store frequently accessed data in the Distributed Cache Service (Redis).
  D. Introduce redundancy to eliminate single points of failure so that when one node fails, other nodes can handle the workload seamlessly.

• Question 137:

  A company uses encryption software that requires security authentication with a dongle (Ukey) before it can be used normally. The company is now undergoing cloudification reform and needs to deploy cloud-friendly services on HUAWEI CLOUD. Which of the following is the most suitable solution for migrating the software to the cloud?

  A. HUAWEI CLOUD does not provide a Ukey cloud migration solution, so it cannot migrate to the cloud.
