Before installing and deploying the IVS application, you need to disable the automatic backup function...

The correct answer is A. TRUE . In IVS deployment practice, background maintenance tasks such as automatic backup can interfere with application installation, service initialization, database operations, and resource locking. For that reason, engineers typically disable automatic backup before beginning installation or deployment on the CSP OM portal. This is consistent with Huawei’s broader operation and maintenance logic, where management-plane activities on the CSP OM portal directly affect application deployment behavior. The material repeatedly uses the CSP OM portal as the control point for cluster and application configuration, for example when engineers need to view BMU-related service addresses through “Application Configuration > Configuration Management > Configuration > Application Name > Two-Node Cluster”

From an implementation perspective, installation requires a stable and uncontested environment. If an automatic backup starts during deployment, file operations, configuration updates, or service restarts may be interrupted, which can lead to incomplete installation or task failure. Therefore, disabling the automatic backup function before IVS installation is a valid preventive measure and should be regarded as a correct statement.
