Question 26

Cloud container instance service CCI provides serverless container (serverless container) introduction, so that users can run containers directly without creating and managing server clusters. In the following description about cloud container instance service CCI, which one is wrong?

A.Cloud container instances provide dedicated container instances, such as running Kata containers

B.Provide rich network access methods and support four-layer and seven-layer load balancing

C.Can call or manage Kubermetes cluster resources

Question 27

Compared with cloud database RDS, Huawei's self-developed database GaussDB has many advantages over cloud database RDS in terms of system architecture and other aspects. Which of the following descriptions related to GaussDB is wrong?

A.There is only one copy of storage, no need to purchase additional storage. If there are more read-only nodes, the storage cost will be saved more

B.There is no longer a standby database, and all read-only databases are in the Active state. And bear the read traffic, making resource utilization higher

C.With multiple storages, when the access volume is large, the read and write performance of the database will be significantly improved

D.All update operations are only logged, and Double write is no longer required. Reduced valuable network bandwidth

Question 28

After configuring the peer-to-peer connection, the cloud operation and maintenance engineer of a company found that the two VPCs still cannot be accessed normally.
Which of the following possible reasons are correct? (Multiple choice)

A.Network parameter configuration error

B.The ECS does not support the peer-to-peer connection function by default, and it needs to be manually enabled to take effect

C.The route of the peer-to-peer connection overlaps with the destination address of the leased line and VPN route

D.A VPN has been configured for the VPC, and its network access has a higher priority than peer-to-peer connections.
