Huawei H13-811_V3.5 Exam With Confidence Using Practice Dumps

Option A is false because deleting historical object versions is not required before versioning can be suspended. Huawei Cloud states that once versioning has been enabled, it cannot revert to the original Disabled state, but it can be suspended. Existing historical versions remain stored in OBS after suspension and may be manually deleted later only if they are no longer required.

Option B is correct. When versioning is enabled, OBS automatically assigns a unique version ID to newly uploaded versions. Objects with identical names are retained as separate object versions distinguished by those IDs.

Option C is also correct. Huawei explicitly supports configuration of OBS versioning through the OBS Console, APIs, and SDKs.

Option D is correct because versioning is disabled by default for newly created buckets. It must be explicitly enabled if the customer wants multiple versions retained instead of allowing a newly uploaded namesake object to replace the current object.

Therefore, A incorrectly adds a prerequisite that Huawei does not impose for suspending versioning.

The statement is FALSE . Although an ECS group does logically organize ECS instances, its placement behavior is the opposite of what the second sentence states. Huawei Cloud ECS groups support the anti-affinity policy , which is designed to place ECS instances belonging to the same group on different physical hosts .

Anti-affinity is an availability and fault-isolation mechanism. If multiple application instances were placed on one physical server, failure of that host could simultaneously disrupt every application instance. Distributing the ECSs across different hosts reduces this correlated-failure risk and improves service reliability, high availability, and disaster tolerance.

Huawei's ECS documentation explicitly states that ECS groups support the anti-affinity policy and that ECSs in an anti-affinity group are deployed on different hosts. When an existing ECS is added to such a group, Huawei Cloud may even reallocate its host so that the placement requirement can be maintained.

Therefore, the first proposition—an ECS group logically groups ECSs—is valid. However, the assertion that ECSs in that group are created on the same physical server by default contradicts the anti-affinity design. Since the overall statement contains this incorrect condition, the correct answer is FALSE .

Option B is incorrect because Huawei Cloud OBS does not allow a bucket that has already had versioning enabled to return to the original Disabled state. Versioning can initially be enabled on a bucket, but once enabled, it can subsequently only be suspended , not disabled.

Option A is correct. With versioning enabled, OBS assigns unique version IDs to uploaded objects, allowing multiple objects with the same key or name to coexist as different versions. This protects against accidental overwrites and provides point-in-time recovery capabilities.

Option C is also correct when a specific historical version is permanently deleted. Each object version is independently identified by its version ID, so deleting one specified version does not inherently remove the other retained versions.

Option D accurately describes the initial state. Huawei states that versioning is disabled by default for newly created OBS buckets. When versioning has never been enabled, uploading a new object with the same name replaces the existing object instead of maintaining multiple historical versions.

The critical distinction is therefore Disabled versus Suspended . Disabled is the initial state; after versioning is enabled, it cannot be restored to Disabled.
