• Question 73:

  Which of the following statements about the government cloud construction mode is incorrect?

  A. The government and enterprises jointly establish a joint venture company for construction, and the government purchases services.
  B. Government direct investment in construction and operation, with government procurement of services.
  C. Government investment or co-construction with enterprises, and service purchase from enterprises.
  D. Sole proprietorship by operating enterprises, with government purchasing services.

• Question 74:

  A complete e-commerce platform typically uses ECS, EVS, CDN, AS, security services, RDS, OBS, and VPC.

  E-commerce businesses require large memory capacity, fast data exchange, high data throughput, and strong monitoring capabilities.

  As a Huawei Cloud OandM expert, which of the following strategies would you recommend to comprehensively monitor and manage the operational status of the e-commerce platform? (Choose four)

  A. ECS serves as the foundation of the e-commerce platform. By installing the Agent plug-in on ECS instances, system-level, active, and fine-grained monitoring services can be implemented.
  B. For large volumes of static data (such as product images and promotional banners), Cloud Eye Service (CES) can use site monitoring to continuously ping the elastic IP addresses of websites or ECS instances, monitoring service portal availability and response time to detect latency issues.
  C. Since the e-commerce business involves multiple HUAWEI CLOUD services such as ECS, CDN, AS, security services, RDS, and OBS, the resource grouping feature can be used to view resource usage, alarms, and health status from a business perspective, simplifying management and improving OandM efficiency.
  D. For services such as RDS, ELB, and VPC used by the platform, cloud service monitoring can be leveraged to view running status and key metrics in real time, and configure alarm rules for precise monitoring of service operations.

• Question 75:

  Which of the following descriptions correctly distinguish the differences between the Dedicated Distributed Storage Service and the Elastic Volume Service (EVS)? (Choose three)

  A. Both Dedicated Distributed Storage and EVS disks can support hybrid deployment of applications such as HPC, database, email, office, and web systems.
  B. Both Dedicated Distributed Storage and EVS disks provide a multi-copy mechanism to ensure high data durability.
  C. EVS disks offer richer specifications than Dedicated Distributed Storage.
  D. The storage pool of Dedicated Distributed Storage is physically isolated, with exclusive resources and storage, while EVS disks share storage pool resources.
  B. Both Dedicated Distributed Storage and EVS disks provide a multi-copy mechanism to ensure high data durability.
  C. EVS disks offer richer specifications than Dedicated Distributed Storage.
  D. The storage pool of Dedicated Distributed Storage is physically isolated, with exclusive resources and storage, while EVS disks share storage pool resources.

• Question 76:

  The container limits CPU and memory usage through cgroup technology. Reasonably setting the request and limit values of container resources can effectively ensure the container's resource usage quota, avoid resource preemption that affects the stability of the operating environment, and not setting an upper limit on container resource quotas can effectively improve node resource utilization.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 77:

  In DRS full data synchronization, a large number of tables are sharded and synchronized concurrently using multiple threads to improve efficiency.

  Normally, tables are sharded based on the primary key, with each shard containing 520,000 records by default.

  During synchronization, Bob discovers that a large table (T1) with a primary key has been divided into many shards -- however, some shards contain more than 520,000 records, while others have fewer.

  Which of the following could be the possible reason? (Choose three)

  A. There is an error in DRS data sharding.
  B. The table is divided by 520,000 records, but the last shard may contain fewer than 520,000 records, resulting in uneven shard sizes.
  C. DRS creates more than 520,000 shards for all tables with primary keys.
  D. The T1 table's primary key is a composite (joint) primary key.
  A. There is an error in DRS data sharding.
  B. The table is divided by 520,000 records, but the last shard may contain fewer than 520,000 records, resulting in uneven shard sizes.
  D. The T1 table's primary key is a composite (joint) primary key.
