Which of the following descriptions of Kubernetes-related concepts is wrong?
- A . The Master node is the cluster control node. Each cluster requires at least one Controller node to be responsible for cluster control.
- B . Node is the workload node, and Docker on the Node is responsible for running the container
- C . NamesSpace is used to classify Pods. Pods of the same type have the same NameSpace.
- D . Pod is the smallest control unit of Kubernetes. Containers are run in Pods. A Pod can run one or more containers.
Which of the following descriptions about Huawei Cloud Stack computing resource expansion is wrong?
- A . If you use Huawei CloudStack Deploy to expand capacity, the cbs-server component will be stopped during the pre-expansion check phase. At this time, a "component failure" error will be reported. The component details are cbs-server, which can be ignored.
- B . During the expansion of computing nodes, some components need to be restarted to take effect, which will not affect the business
- C . Business delivery is not allowed during the expansion period, and new business delivery may fail
- D . During the expansion period, the server to be expanded will restart multiple times, and may report an "abnormal host status" alarm, which needs to be handled manually.
An enterprise needs to use Cloud Container Engine (CCE) to implement high-availability deployment of business containers. Which of the following is not a deployment principle that the enterprise should follow for business deployment?
- A . Set workload affinity rules to distribute Pods on the same node in the same availability zone as much as possible to ensure horizontal business interaction performance
- B . When creating a workload, the number of instances must be greater than 2.
- C . The cluster selects the high availability mode of 3 control nodes
- D . Create multiple node pools, deploy different node pools in different availability zones, and expand nodes through node pools
A company deployed the Rainbow tool (default configuration) to migrate business hosts. The company’s IT engineer modified the login account and password of the server where Rainbow was deployed for operation and maintenance needs. Which of the following descriptions of the impact of this operation by the engineer is correct?

- B . The Tomcat running account needs to be modified synchronously
- C . Database business accounts need to be modified synchronously
- D . The database operation account needs to be modified synchronously
An enterprise uses Huawei Cloud Stack to carry private cloud services. It currently deploys an ARM architecture computing resource pool and uses IP-SAN to carry business storage. Due to the expansion of business scale, it needs to expand the corresponding resources. Which of the following analyses about the expansion of the enterprise’s resources is correct?
- A . KVM resources and BMS resources can be planned in the newly created AZ at the same time
- B . Create a new storage pool first and register a new storage backend. It is not recommended to expand the capacity of the original storage pool.
- C . When newly deploying X86 computing resources, you can directly expand them to the original resource pool
- D . When multiple AZs are expanded and share a storage pool, the storage backend and thin allocation ratio of each AZ must remain the same
An engineer is designing cloud server backup and cloud disk backup services for the Huawei Cloud Stack deployed by his company. Which of the following descriptions of the engineer’s network plane planning is correct?
- A . The Product Storage plane is isolated from the storage plane of the computing nodes.
- B . eBackup_OM plane reuses OM_Service plane
- C . The eBackup_Storage plane communicates with the backup storage management plane
- D . The eBackup_OM plane communicates with the production storage management plane
When an enterprise engineer was performing routine maintenance on Huawei Cloud Stack, he found that all the requests for the deployed key management service were responded to, but some of the responses were failure information. Which of the following descriptions of the possible causes of this phenomenon is wrong?
- A . Network failure between the key management service and the database
- B . The KMS process of scc-Serice is abnormal
- C . A single HSM fails and cannot provide external services
- D . The network between the key management service and the HSM is disconnected
Which of the following descriptions of the Region concept in Huawei Cloud Stack is wrong?
- A . Region belongs to the regional concept of L0 layer, that is, geographical area
- B . The management planes in the region are interconnected, and some high-security services can be deployed in a separate region.
- C . If the latency between physical data centers exceeds 100ms, they need to be planned into different regions.
- D . Region is a circle with delay as radius
Which of the following is not a component of Kubarnetes?

- C . OMAccess VRF mainly carries remote operation and maintenance access or local operation and maintenance access traffic
- D . DMZ VRF is used to carry internal operation and maintenance management traffic and various cloud service internal data communication traffic
