In HUAWEI CLOUD Stack, the weak affinity policy of a VM group schedules VMs in the same group to one host when resources are sufficient. If resources are insufficient, the rule can be broken.
The correct answer is A (TRUE) . Huawei Cloud Stack compute resource management documentation explicitly describes the behavior of soft-affinity , which is the practical equivalent of weak affinity in scheduling policy terms. Huawei states that if host resources are sufficient, VMs in the same soft-affinity group will be scheduled to the same host . It further states that if resources are insufficient or the current host is faulty, the VMs can be scheduled to different hosts . This matches the wording of the question almost exactly.
Huawei ECS group documentation also explains that an ECS group can be configured with affinity, anti-affinity, weak affinity, or weak anti-affinity policies, which confirms that weak affinity is an officially recognized scheduling policy in Huawei Cloud Stack. The “weak” part means the scheduler prefers a placement rule but is allowed to violate it when necessary to ensure successful deployment or continuity.
Therefore, the statement accurately reflects Huawei’s documented scheduling behavior: under normal conditions, VMs tend to be placed together, but if resources are inadequate, the rule may be broken. So the verified answer is TRUE .
