Huawei H13-831 Online Questions & Answers

• Question 271:

  Fill in the blank

  An enterprise uses Elastic Cloud Server (ECS) to deploy its own database engine. The database engine requires multiple ECS instances to form a cluster, and the engine stores data across all instances to prevent node corruption and data loss. Since holding data in the file system requires extremely high throughput and very low latency, in this scenario, you can select _________ storage scheme to implement it.

  Local disk

• Question 272:

  As an important part of the daily application management of enterprises, alarm management can be performed through the AOM (Application Operations and Maintenance) alarm management function after business applications are migrated to the cloud. Which of the following descriptions about alarm threshold rule settings in AOM are correct? (Choose three)

  A. Threshold alarms created in batches can be applied to all services under the tenant.
  B. The default batch static threshold rule monitors all hosts or all components.
  C. Static threshold rules can set threshold conditions on indicators of applications (such as application resource usage, throughput, and application request errors).
  D. Once a set threshold condition is triggered, a threshold alarm will be generated synchronously, and the user can receive the corresponding notification through email or SMS.
  A. Threshold alarms created in batches can be applied to all services under the tenant.
  B. The default batch static threshold rule monitors all hosts or all components.
  C. Static threshold rules can set threshold conditions on indicators of applications (such as application resource usage, throughput, and application request errors).

• Question 273:

  In the early technical selection of a big data offline batch processing platform, which of the following big data components does not belong to the offline batch processing business scenario?

  A. HDFS

• Question 274:

  A multinational enterprise group has an application system that supports the group's global sales business. In order to better meet user requirements, the group plans to migrate this application system to HUAWEI CLOUD. As the person in charge of the application system, which of the following are suitable cloud requirements? (Choose three)

  A. Provide capacity based on the estimated theoretical maximum peak, even if this may result in idle or insufficient utilization of expensive resources during certain periods.
  B. A complete off-site high availability and disaster recovery solution is required across regions. The high-availability design in this scenario includes a "three centers in two regions" disaster recovery solution and an active-standby disaster recovery solution.
  C. Services should be decoupled and deployed so that different components run on separate ECS instances. A layered deployment architecture can be used -- for example, web tier, business tier, and database tier -- with security managed through separate subnets.
  D. When migrating to the cloud, high availability must be designed for dual-AZ scenarios, including active-active data center solutions, active-standby disaster recovery, cluster-based services, and resource deployment across two AZs using ELB to achieve dual-AZ load balancing.
