  A. Verify that the data is available
  B. Ensure that HUAWEI CLOUD service systems and databases are normal
  C. Map to the test environment as required
  D. Ensure that the link between the test environment and HUAWEI CLOUD service systems is normal
  A. Verify that the data is available

• Question 423:

  A customer's business flow is as follows:

  EIP ELB ECS Middleware (Redis and Kafka) RDS.

  Cloud services and applications are deployed in a single-AZ high-availability mode, and the customer has specific requirements (RTO < 3 hours).

  Now the customer needs to plan for an application-level disaster recovery scenario.

  Which of the following solutions cannot meet the requirements?

  A. The update frequency of Web and application service servers can be synchronized with the production update on the disaster recovery side, and images can be created for cloud servers; the disaster recovery side of the application remains running.
  B. Use the Intelligent DNS service to control business access traffic - under normal conditions, 100% of user traffic is directed to the production center, and during a failure, 100% of user traffic is switched to the disaster recovery center.
  C. Customers regularly conduct disaster recovery drills through manual or scripted methods.
  D. The database adopts a primary/standby disaster recovery mode, with one side as the primary and the other as the standby. Appropriate synchronization technology can be used for active-standby setups of different database types, including through third-party tools.
  A. The update frequency of Web and application service servers can be synchronized with the production update on the disaster recovery side, and images can be created for cloud servers; the disaster recovery side of the application remains running.

  D. Data writing is random write, and the writing efficiency is high.
  A. It has the characteristics of high throughput and scalability.
  B. Clusters can be built based on a large number of inexpensive hardware.
  C. At any moment, only one client can perform write operations.

• Question 426:

  During the migration of applications to the cloud, the main responses for risk points that may cause data inconsistencies are as follows:

  Incremental synchronization is coordinated with multiple full synchronizations, and the last synchronization requires stopping the source server's write operations.

  Stop the source service writes before migration, and migrate the full data.

  Before migration, the customer should back up the source data.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 427:

  When evaluating migration risk strategies, business correlation analysis is required. Business correlations and dependencies can be analyzed by collecting customer source information, organizing business architecture, and analyzing business relationships and dependencies.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 428:

  When you use the HUAWEI CLOUD Object Storage Migration Service (OMS) for data migration, you can synchronize and delete the destination bucket object when the corresponding object on the source side is deleted.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 429:

  In the era of big datA. data is the core asset of users. Huawei Public Cloud will continue to uphold what it has made to society over the years

  The promise of "not touching the application, not touching the data" ensures the security of users' core assets. To secure data in the data warehouse service Gaus D B (DWS), Which of the following are the correct options? Multiple selection

  In the era of big data, data is the core asset of users. Huawei Public Cloud has long upheld its commitment to society with the promise of "not touching the application, not touching the data", ensuring the security of users' core assets.

  To ensure data security in the Data Warehouse Service (GaussDB DWS), which of the following options are correct? (Choose two)

  A. GaussDB (DWS) runs in an anti-interference container environment that is not shared with other tenants, physically isolating the possibility of data leakage caused by shared computing resources.
  B. In GaussDB (DWS), user business data is directly stored on the cloud hosts of the cluster. These cluster cloud hosts are invisible to users and only provide data warehouse access services. Neither users nor public cloud administrators can log in to the GaussDB (DWS) cluster ECS for operations.
  C. The GaussDB (DWS) network is divided into a business plane and a management plane, which are physically isolated to ensure the security of both service and management networks
  D. The backup data of GaussDB (DWS) is stored on OBS in the form of snapshots. The data is used only for backup and recovery purposes and cannot be accessed by any external users, including GaussDB (DWS) users themselves.
  B. In GaussDB (DWS), user business data is directly stored on the cloud hosts of the cluster. These cluster cloud hosts are invisible to users and only provide data warehouse access services. Neither users nor public cloud administrators can log in to the GaussDB (DWS) cluster ECS for operations.
  C. The GaussDB (DWS) network is divided into a business plane and a management plane, which are physically isolated to ensure the security of both service and management networks

• Question 430:
