A node pool is a group of nodes in a cluster with the same configuration, and the f-node pool contains one node or nodes. What are the correct items in the following description of node pools?

A.

When the node resources required by the cluster fluctuate little, dynamic operation and maintenance through the dynamic elastic scaling capability of node pools is used to improve operation and maintenance efficiency and reduce operating costs

B.

The cluster needs to frequently expand and shrink the nodes, and the M node pool can reduce the operation cost

C.

D. There are many heterogeneous nodes in the cluster (different model configurations), and node group management can be standardized through node pools

Cloud Data Migration CDM is an efficient, easy-to-use bulk data migration service. Which of the following security capabilities does the service provide to protect user data?

A.

Instance isolation: Users of theCDM service can only use the instance created by themselves, and the instance is isolated from each other and cannot be accessed by each other

B.

B. No intermediate storage: During the data migration process, CDM only handles data mapping and transformation, and does not store any user data or fragments

C.

C. System hardening: The operating system of the CDM instance has special security hardening, and the attacker cannot access the CDM from the Internet

The operating system of the instance

D.

D. Key encryption: Users create keys for various data sources entered by connections on CDM, and CDM uses strong encryption to store them in the CDM database
