  Which of the following configurations are correct? (Choose two)

  A. To avoid wasting resources during off-peak hours, it is recommended to use a "cycle trigger" -- when CPU/memory utilization is below 40%, reduce xxx instances.
  B. For scheduled monthly in-game events where player activity increases, configure a "cycle trigger" before the event (e.g., at 12:00 on August 8) to increase xxx instances.
  C. When a new game is launched and a large number of players may log in simultaneously, it is recommended to use an "indicator trigger" -- for example, when CPU or memory usage exceeds 70%, increase xxx instances.
  D. If the daily peaks and troughs of player activity are evident (e.g., peaking in the afternoon and evening), it is recommended to use a "cycle trigger" -- for example, from January 1, 2022, to January 1, 2023, add xxx instances at 13:00 each day.
  B. For scheduled monthly in-game events where player activity increases, configure a "cycle trigger" before the event (e.g., at 12:00 on August 8) to increase xxx instances.
  C. When a new game is launched and a large number of players may log in simultaneously, it is recommended to use an "indicator trigger" -- for example, when CPU or memory usage exceeds 70%, increase xxx instances.

• Question 417:

  Object Storage Service (OBS) provides on-demand and resource plan billing modes, including storage capacity, traffic, number of requests, and data retrieval. When using the OBS service, which of the following traffic directions does not incur charges?

  A. Back-to-origin traffic: Downloading OBS data through HUAWEI CLOUD CDN when data is fetched from the origin.
  B. Public network outbound traffic: Outgoing traffic generated by downloading standard storage data from OBS over the Internet.
  C. Internal/public network inflow traffic: Incoming traffic generated by uploading data to OBS over the intranet or the Internet.
  D. Cross-region traffic: Outflow traffic generated when using the cross-region function to transfer source bucket data to a destination bucket in another region.
  C. Internal/public network inflow traffic: Incoming traffic generated by uploading data to OBS over the intranet or the Internet.

• Question 418:

  A company's offline IDC small systems have been deployed in its data center but now need to be migrated to the HUAWEI CLOUD environment. The business must be deployed efficiently with limited resources, and OandM personnel are already familiar with the existing deployment architecture. Currently, five physical hosts handle the business workload. To improve host utilization, multiple modules are deployed on each physical host - for example, the web front end, middleware, applications, and databases are all hosted together.

  When migrating to the cloud, which of the following methods should OandM personnel choose?

  A. Based on the ports opened by the offline service system, configure the appropriate ports required by each service module on the cloud following security best practices.
  B. After migrating to the cloud, OandM personnel open ports 22 and 3389 on each host for remote maintenance, improving flexibility and work efficiency. Utilize various cloud services and flexible resource features -- select appropriate specifications, deploy web and application modules on the same virtual host, and use cloud-provided services for middleware and databases.
  C. For architectural and maintenance simplicity, directly replicate the offline model by purchasing five bare metal servers on the cloud and deploying services as before.

• Question 419:

  The HUAWEI CLOUD Data Lake Exploration Service (DLI) is applicable to which of the following scenarios? (Choose three)

  A. Smart Parking Management: Traditional parking lots rely on manual management, making it difficult to monitor parking spaces in real time. This leads to long entry/exit and payment times and low utilization efficiency. DLI enables intelligent management of vehicle entry, exit, billing, and parking space status.
  B. Telecom Data ETL: Operators need to perform ETL processing on massive, diverse data to provide distributed datasets for large-scale batch computing.
  C. Connected Vehicle Cloud: Traditional car manufacturers need to collect and analyze daily vehicle metrics (battery, engine, tire pressure, airbag, etc.) to provide maintenance feedback to vehicle owners. By building a connected vehicle cloud platform and vehicle OS, integrating internet applications with in-car scenarios, they can enable digital transformation, enhance user experience, increase competitiveness, and boost sales growth.
  D. Game Operations Analysis: Game operation teams need to obtain metrics such as new users, active users, retention rate, churn rate, and payment rate in real time to understand game performance and plan responsive strategies.
