  A. RDS master-slave deployment automatically switches to the standby node when the master node fails.
  B. When the system is under attack, OandM personnel enter emergency response mode to analyze and mitigate the issue.
  C. Auto Scaling automatically replaces a failed node to ensure system continuity.

  D. The ELB health check detects server node failures and stops routing new requests to the failed node.

• Question 245:

  After the host connection configuration is completed, a user does not collect logs through the Log Service. Regarding the possible causes of this issue, which of the following descriptions is incorrect?

  A. The acquisition path configuration file of the same host is incorrect.
  B. After completing the configuration, you need to wait - then the logs will start reporting.
  C. The same log collection path of the host has already been configured in AOM.
  D. The host access configuration may not be standardized.
  A. The acquisition path configuration file of the same host is incorrect.

• Question 246:

  In an HPC (High-Performance Computing) scenario, enterprise users can upload data to Object Storage Service (OBS) via direct upload or Data Express. Which of the following descriptions about this scenario architecture are correct? (Choose three)

  A. The REST API provided by OBS is fully developed, and the console, SDK, and various tools are available for users to create OBS buckets and upload objects to them.
  B. The file semantics and HDFS semantics provided by OBS allow direct mounting of OBS to HPC flavor nodes. In big data or AI analysis applications, it provides convenient and efficient data read, write, and storage capabilities for all aspects of high-performance computing.
  C. For large file storage, SFS can be used as an alternative to OBS.
  D. Data Express supports offline mailing to deliver data directly to an OBS bucket.

• Question 247:

  HUAWEI CLOUD provides multiple disaster recovery (DR) capabilities and selects the optimal disaster recovery solution based on customer needs. Which of the following descriptions are correct? (Choose three)

  A. Hot standby disaster recovery: During normal operation, both the primary and standby web and application servers run normally. The standby system does not provide external services during normal operation. Because the disaster recovery site is continuously running, the RTO can reach the minute level, ensuring high reliability.
  B. Cold standby disaster recovery: A relatively economical database-level DR solution. When the on-premises database fails, a backup database on the cloud remains available.
  C. Application active-active: When both primary and standby web and application servers are running and providing external services simultaneously, disaster recovery reliability is high because the DR site is always active.
  D. Database disaster recovery: An economical application-level DR solution in which the disaster recovery-side application virtual machines are not started under normal circumstances. Disaster recovery costs are reduced, and automatic DR management (including switchover and drills) can be achieved through third-party tools.

• Question 248:

  In the disaster recovery solution, 100% of user traffic is diverted to the production center under normal conditions. When the production site fails, the database of the disaster recovery site is switched to the main database state, and then the DNS authorization is modified so that the production site is 0% and the disaster recovery site is 100%.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 249:
