Huawei H13-831 Online Questions & Answers

• Question 361:

  The data sets in ModelArts and the corresponding data storage locations are stored in Object Storage Service (OBS).

  A. True
  B. False
  A. True

• Question 362:

  Data Replication Service (DRS) is an easy-to-use, stable, and efficient cloud service for smooth database migration and continuous synchronization of databases. Objects that can support schema migration include tables, views, synonyms, triggers, stored procedures, stored functions, and custom types.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 363:

  The primary instance of Data Replication Service (DRS) supports building a primary/standby high-availability architecture. When a natural disaster suddenly occurs in the area where the primary instance (Master) is located and the standby node (Slave) cannot be connected, you can switch the remote disaster recovery instance to the primary instance and quickly restore service access by modifying the database connection address on the application side. The real-time disaster recovery function provided by DRS enables real-time synchronization between the primary instance and cross-region disaster recovery instances.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 364:

  You are migrating Redis persistent files from an OBS bucket to the Distributed Cache Service (DCS). Which of the following descriptions about the migration task are correct? (Choose two)

  A. Select OBS as the migration type.
  B. Select Backup files as the migration type.
  C. It is not recommended to import files generated by higher-version Redis instances into lower-version Redis instances.
  D. During the migration process, a Redis instance will be automatically created in the background.
  B. Select Backup files as the migration type.
  C. It is not recommended to import files generated by higher-version Redis instances into lower-version Redis instances.

• Question 365:

  ICAgent is the collector of the Application Operations and Maintenance Management Service (AOM). It runs on each host to collect metrics, logs, and application performance data in real time. As long as the ICAgent is properly installed, AOM can immediately begin data acquisition.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 366:

  Which of the following monitoring types can you use when using the Site Monitoring feature of HUAWEI CLOUD CES (Cloud Eye Service)? (Choose three)

  A. HTTP or HTTPS
  B. TCP
  C. PING
  D. SSH
  A. HTTP or HTTPS
  B. TCP
  C. PING

• Question 367:

  Which of the following descriptions about using HPA + CA to achieve automatic scaling of workloads and node linkage is incorrect?

  A. The CCE Cloud Container Engine supports the creation of CA policies, scales capacity according to CPU/memory allocation ratio, and periodically scales nodes according to time.
  B. HPA expands according to monitoring standards, and when the cluster resources are insufficient, the newly created pod will be in the Running state. CA checks all Running pods and, according to the user-configured scaling policy, selects the most suitable node pool to scale.
  C. Under normal circumstances, the two need to be used together, because HPA requires sufficient resources in the cluster to successfully expand. When the cluster resources are insufficient, CA needs to expand the nodes so that the cluster has sufficient resources.
  D. When the cluster has a large amount of spare resources after HPA scale-in, CA needs to scale in nodes to release resources and avoid waste.
  B. HPA expands according to monitoring standards, and when the cluster resources are insufficient, the newly created pod will be in the Running state. CA checks all Running pods and, according to the user-configured scaling policy, selects the most suitable node pool to scale.

• Question 368:

  To prevent data stored in OBS from being accessed or stolen by unauthorized users, OBS supports Referer-based anti-hotlinking, which relies on the Referer field in the HTTP header. This method supports configuring whitelists for access control but does not support configuring blacklists.

  A. True
  B. False
  B. False

• Question 369:

  The cloud-native data lake solution in HUAWEI CLOUD MapReduce provides a leading architecture with separated storage and computing for unstructured data scenarios such as massive government images and videos. OBS on the cloud replaces MRS local storage as a big data store. Which of the following descriptions about the OBS service in this solution is incorrect?

  A. Replace the EC algorithm with three replicas to reduce unit capacity cost.
  B. Provides standard storage, low-frequency access storage, and archive storage in three categories.
  C. Storage and compute technologies need to be expanded separately.
  D. Distributed architecture with horizontal scalability.
  A. Replace the EC algorithm with three replicas to reduce unit capacity cost.

• Question 370:

  A game company recently released a new online game product that was warmly welcomed by users after its launch. However, during the evening rush hour, users often experience login congestion and cannot access the system normally, resulting in poor user feedback. The company has requested a quick resolution. As the company's IT architect, which of the following would be the appropriate solutions? (Choose four)

  A. Improve performance by adding more servers to the load-balanced network so that incoming requests can be distributed to different back-end systems according to policy.
  B. Replace one large resource with multiple smaller resources to reduce the impact of a single failure on the entire system.
  C. Build the system on a cloud-based, dynamically scalable architecture to support good user experience and ensure that growth in user volume or data size does not degrade performance.
  D. Reduce interdependencies in the system by allowing various components to interact only through specific, technology-independent interfaces (e.g., RESTful APIs), hiding technical implementation details so that the underlying implementation can be modified without affecting other components.
