• Question 81:

  A user deploys a set of web applications on HUAWEI CLOUD and configures ELB (Elastic Load Balancer) on the access side to perform traffic sharing. However, after the service is configured, it is found that the backend service cannot be accessed through load balancing. Which of the following could be the possible causes of this situation? (Choose three)

  A. The backend server configuration and service configuration are incorrect.
  B. The listener has enabled access control and restricted client access.
  C. The security group inbound policy is misconfigured.
  D. The allocation policy type of the backend server group is set to the weighted polling algorithm.
  A. The backend server configuration and service configuration are incorrect.
  B. The listener has enabled access control and restricted client access.
  C. The security group inbound policy is misconfigured.

• Question 82:

  Many enterprises need to migrate databases to the cloud. Some customers, after cutover, use the cloud database (B) directly for production, while the on-premises database (A) is retained only for historical data backup. However, for risk control, some customers require a data consolidation period after cutover, during which data in the cloud database is synchronized in real time back to the on-premises database (A or C), allowing quick rollback if problems occur in the cloud. As a cloud architect, which of the following methods can meet the latter requirement?

  A. Create an A B full + incremental cloud migration task after service cutover.
  B. Create an A B full + incremental cloud migration task before service cutover.
  C. Create A B cloud migration tasks after cutover to maintain data consistency.
  D. Create a one-way disaster recovery task (A B) before migration, and after cutover, switch the direction to B A to enable reverse synchronization.
  D. Create a one-way disaster recovery task (A B) before migration, and after cutover, switch the direction to B A to enable reverse synchronization.

• Question 83:

  Compared with cloud backup and disaster recovery from the perspective of purpose and use, cloud backup is mainly to avoid data loss, generally using snapshots, backups, and other technologies to create data backup copies. In the event of a primary site failure, it can take over the business. Disaster recovery is mainly to avoid business interruption, using technologies to build business backup hosts and store data in different locations, restoring user data through historical data copies in case of a failure.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 84:

  Natural Language Processing (NLP) is an artificial intelligence technology.

  For all types of enterprises and developers, the cloud service for image text analysis and mining is designed to help users efficiently process text contained in images, and is often used in scenarios such as intelligent question-answering systems, text analysis, content recommendation, and translation.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 85:

  Which of the following scenarios describe the X-axis horizontal scalability of an AKF expansion cube? (Choose three)

  A. An Internet company experiences a surge in the number of users, who are distributed across multiple regions. Multiple clusters are established in Beijing, Shanghai, Sichuan, and other areas according to the geographic distribution of users.
  B. The number of passengers accessing a taxi application increases, and the passenger services in the application are independently separated and expanded as needed.
  C. To ensure data reliability, a financial enterprise deploys its database in active-standby mode to achieve high reliability.
  D. An e-commerce application runs multiple instances during peak business hours and uses load balancing to distribute front-end traffic across the cluster.

  B. Use ELB load balancing
  C. Use CDN acceleration
  D. Deploy services in multiple regions
  C. Use CDN acceleration

• Question 88:

  Regarding the host monitoring capabilities that HUAWEI CLOUD CES (Cloud Eye Service) can provide, which of the following descriptions is incorrect?

  A. After the ECS installs the Agent, CES can monitor the processes of the ECS, collect CPU and memory consumption of active processes, and gather information such as the number of open files.
  B. After the ECS installs the Agent, CES can monitor the ECS processes, configure custom monitoring controls, collect the number of key processes, and obtain the running status of key processes at any time.
  C. When the ECS does not have an Agent installed, CES can still perform basic monitoring of the ECS and monitor the CPU usage of the ECS.
