Question 26

In the scenario where HUAWEI CLOUD Stack global and region zones are deployed together, the CPU architectures of the management nodes in the primary region must be the same. In the scenario where HUAWEI CLOUD Stack global and region zones are deployed independently, the CPU architectures of the management nodes in the global zone can be different from those of the management nodes in the primary region.

  1. TRUE
  2. FALSE

Question 27

An engineer runs the docker run -d busybox ping -c 100 www.huawei.com command to create a container.Which of the following commands can be executed when the container is running without impacting tasks currently running?

  1. docker ps -a
  2. docker attack d1 echo $? (d1 indicates the container ID.)
  3. docker run -it d1 echo $? (d1 indicates the container ID.)
  4. docker exec d1 echo $? (d1 indicates the container ID.)

Question 28

Which of the following statements about container orchestration engines are true? (Choose all that apply.)

  1. Using Mesos and Marathon together is suitable for large-scale cluster scheduling and management.
  2. Kubernetes is developed by Google based on the Borg project.
  3. DCOS is a platform that adds a large number of customized peripheral components based on Mesos.
  4. Swarm seamlessly integrates various runtimes.

Question 29

Which of the following statements about RPO are true? (Choose all that apply.)

  1. If a service system backs up data every four hours, the RPO of the system is less than or equal to four hours.
  2. The service volume of a service system has obvious periodic rules. To balance costs and security, you can set a large backup interval during off-peak hours and a small backup interval during peak hours.
  3. RPO refers to the tolerable data loss amount of a service system after a disaster occurs.
  4. The RPO value reflects the disaster recovery capability of the system. A larger RPO value indicates a stronger disaster recovery capability of the system.

Question 30

Which of the following statements are true about CSBS/VBS backup and restoration in HUAWEI CLOUD Stack? (Choose all that apply.)

  1. Before configuring cross-region replication, ensure that the management plane network and backup storage plane network of the eBackup Server&Proxy nodes in the source region can communicate with those in the target region.
  2. Before configuring cross-region replication, ensure that the management network between the production storage and backup storage is normal.
  3. CSBS reads data from production storage snapshots and writes the data to backup storage. VBS directly reads data from production storage and writes the data to backup storage.
  4. VBS does not support cross-region replication.
