When the HyperReplication feature of Huawei scale-out storage is applied, If the properties of a consistency group are modified, the property modification will be synchronized to each pair in the consistency group. That is, the properties of the consistency group prevail.

The statement is true. A consistency group in Huawei's HyperReplication feature is designed to ensure data consistency across multiple LUNs or file systems that are part of a single application. To maintain this consistency and simplify management, properties configured at the consistency group level (such as replication mode, synchronization speed, and recovery point objective - RPO) are automatically applied to all replication pairs within that group. If a property is modified for the consistency group, the change is propagated to all member pairs, ensuring uniform behavior. The group's properties always prevail over individual pair settings.

B. The statement accurately describes the fundamental behavior of consistency groups in storage replication technologies, including Huawei HyperReplication. There is no inaccuracy in the claim.

- Huawei OceanStor Dorado V6 HyperReplication Feature Guide, Section: "Feature Principles > Consistency Group". This section explicitly states that a consistency group ensures that the data of all members is at the same point in time. It further explains that when you create a consistency group, you set properties for it, and these properties apply to all remote replication pairs added to the group.

- Huawei OceanStor Dorado 8000 and 18000 V6 Administrator Guide, Section: "HyperReplication > Managing a Consistency Group > Modifying the Properties of a Consistency Group". The documentation confirms that modifying properties like speed or RPO at the group level will apply the changes to all pairs within it.
