Q28 Multiple choice

When using Cloud Data Migration (CDM), the following potential threats may exist:

Internet threats: Malicious users may attack CDM through the CDM control console.

Data center threats: Malicious CDM administrators may attempt to obtain users' data source access information.

Malicious user threats: Malicious users may steal other users' data.

Data exposure threats: Data leakage may occur when data is migrated over the public network.

To mitigate these risks, which of the following mechanisms does CDM provide to help protect end users? (Choose four)

Select all that apply.

A
CDM uses a separate virtual machine for each user to run its own CDM instance. The instances between users are completely isolated and secure, ensuring that a malicious user cannot access
another user's instance.
B
Users must provide the access username and password information of both the source and destination
data sources to the CDM system to complete data migration. CDM provides a three-level protection mechanism to prevent CDM administrators from accessing this information or attacking users' critical data sources.
C
Under the extractrite model of CDM, even if CDM is bound to an Elastic IP, the ports are not opened to the Elastic IP, preventing attackers from accessing or attacking CDM through it. However, when migrating data over the public network, because user data sources are exposed on the public network and subject to third-party attacks, it is recommended to protect the source server using an access control (AC) domain firewall, such as allowing access requests only from EIPs bound to CDM.
D
You cannot log in to the CDM console directly through the Internet. CDM provides a two-tier security mechanism to ensure secure access control.
