• Question 235:

  After a Pod in a HUAWEI CLOUD CCE cluster is scheduled to a node, it remains on the node until the Pod is terminated or deleted.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 236:

  The workflow for a Content Delivery Network (CDN) has the following steps:

  1. The user enters the website domain name (e.g., www.example.com ) in the browser, initiating a domain name resolution request to the local DNS.

  2. The local DNS checks the cache for www.example.com. If an IP address record exists, it is returned directly to the end user; if not, the DNS server initiates an authoritative DNS query to the website's domain.

  3. The request is directed to the CDN service.

  4. The web DNS service resolves that the domain name has a CNAME record, e.g., www.example.com.cdn.huawei.com.

  5. The user obtains the CDN node IP address with the fastest response.

  6. After obtaining the IP address of the optimal node, the browser sends an access request to that CDN node.

  7.

  The CDN intelligently resolves domain names and returns the IP address of the CDN node with the fastest response to the local DNS. Which of the following shows the correct order of the CDN request flow?

  A. 1-2-4-5-3-7-6
  B. 1-2-4-3-5-7-6
  C. 1-2-4-3-7-5-6
  D. 1-2-3-4-5-6-7
  C. 1-2-4-3-7-5-6

• Question 237:

  After purchasing basic cloud services such as HUAWEI CLOUD EPS and EVS, and deploying an open-source MySQL database on ECS, you find that the database's SQL read and write operations are slow. Which of the following user actions are correct? (Choose two)

  A. If database read/write latency is suspected to be due to slow disk I/O, report the issue to HUAWEI CLOUD engineers to verify whether disk performance meets the promised specifications.
  B. The user can identify which table has slow performance, and if no suitable index exists, create a new one to optimize queries.
  C. If the latency is caused by high network delay or a bandwidth bottleneck within the purchased range, report the issue to HUAWEI CLOUD engineers for assistance.
  D. To resolve the issue quickly, the user can skip initial troubleshooting and directly report the fault.
  A. If database read/write latency is suspected to be due to slow disk I/O, report the issue to HUAWEI CLOUD engineers to verify whether disk performance meets the promised specifications.
  C. If the latency is caused by high network delay or a bandwidth bottleneck within the purchased range, report the issue to HUAWEI CLOUD engineers for assistance.

• Question 238:

  After creating a ConfigMap object in a CCE cluster, there are usually two ways for workloads to use configuration items:

  one is to set workload environment variables through ConfigMap, and the other is to mount the ConfigMap to the workload's data volume.

  After the workload is successfully created, if the content in the ConfigMap changes, which of the following descriptions is correct?

  A. Environment variables set by ConfigMap are automatically updated, and when mounted in non-subPath mode, the contents of the ConfigMap volume are not updated synchronously.
  B. Environment variables set by ConfigMap are not automatically updated, and when mounted in non-subPath mode, the contents of the files in the ConfigMap volume are updated synchronously.
  C. Environment variables set by ConfigMap are automatically updated, and when mounted in non-subPath mode, the contents of the ConfigMap volume are also updated synchronously.
  D. Environment variables set by ConfigMap are not automatically updated, and when mounted in non-subPath mode, the contents of the files in the ConfigMap volume are not updated synchronously.
  B. Environment variables set by ConfigMap are not automatically updated, and when mounted in non-subPath mode, the contents of the files in the ConfigMap volume are updated synchronously.

• Question 239:

  As long as the conditions for latency and isolation are met, a physical Availability Zone (AZ) can belong to two physical AZ groups at the same time.

  A. True
  B. False
  A. True

• Question 240:

  When performing application cloud migration, business downtime is a key metric for evaluating migration efficiency. Which of the following statements are correct? (Choose two)

  A. For online migration, downtime equals the sum of the final incremental data synchronization time and service switchover time.
  B. Online migration can significantly reduce downtime.
  C. For offline migration, downtime equals the sum of the final incremental synchronization and switchover times, making downtime the same as in online migration.
  D. In all cases, online migration is always the optimal solution.
  A. For online migration, downtime equals the sum of the final incremental data synchronization time and service switchover time.
  B. Online migration can significantly reduce downtime.
