Free Practice Questions for Huawei H13-811_V3.5 Exam

Answer : B, C

Statements B and C are false. Huawei Cloud distinguishes alarm-based, scheduled, and periodic Auto Scaling policies. An alarm policy triggers a scaling operation in response to monitored metrics such as CPU utilization. Scaling ''every three hours'' is time-interval behavior and therefore belongs to a periodic policy, not an alarm policy. This makes B incorrect.

Statement C is also incorrect. The expected number of instances is the desired number of ECS instances that should currently run within an AS group. Huawei specifies that this value must remain between the configured minimum and maximum instance counts. It can be modified manually or changed through scheduled, periodic, or alarm-based policies. It is not synonymous with the minimum instance count during peak hours.

Statement A is valid because an AS configuration can use a Huawei Cloud public image; Huawei's AS configuration parameters explicitly support public, private, and shared images.

Statement D is also valid. Huawei specifies that when an existing ECS is manually added to an AS group, the ECS must not already be a member of another AS group.

Consequently, the two false statements are B and C.

Answer : A, B, D

The major CTS functions represented by the options are trace recording, trace query, and trace transfer, making A, B, and D correct.

Trace recording captures operations performed through the Huawei Cloud management console, through APIs, and operations initiated by supported cloud services. These records provide an audit trail containing information such as the operator, operation time, resource, operation result, and associated request data.

Trace query allows administrators and auditors to search recent operational records on the CTS console using criteria such as trace source, resource type, operator, trace status, and operation type. This is essential for security auditing, compliance investigation, and troubleshooting.

Trace transfer provides longer-term retention and centralized analysis. CTS can package operation records into trace files and transfer them to supported destinations such as OBS or LTS for preservation and subsequent processing.

Option C, OS monitoring, does not belong to CTS. Operating-system performance monitoring is primarily a Cloud Eye/server-monitoring capability rather than an audit-trace function.

Huawei's official CTS documentation expressly identifies recording, querying, and transfer among its core service functions.

Answer : A

The statement is TRUE. Huawei Cloud OBS provides several resource-based authorization mechanisms, including bucket policies and object policies. Their principal distinction is the scope of resources to which they apply.

Huawei's official OBS Permission Configuration Guide explicitly states that an object policy applies to only one object in a bucket, whereas a bucket policy applies to multiple objects or all objects within the bucket. This enables administrators to select the authorization mechanism that best matches the required granularity.

An object policy is useful when permissions must be configured specifically for an individual object, such as granting another principal read or write permissions to one particular resource without broadening access to the rest of the bucket.

A bucket policy supports broader authorization scenarios. Its policy statements can define principals, actions, resources, effects, and conditions to grant or restrict access to selected objects, prefixes, or the entire bucket. Typical uses include allowing another Huawei Cloud account to access specified OBS resources or granting IAM identities access to defined bucket content.

The question therefore correctly distinguishes object-level policy scope from bucket-level multi-object policy scope.

Answer : D

Option D is incorrect. The HCIA-Cloud Service V3.5 comparison positions SFS Capacity-Oriented as the large-capacity, high-bandwidth, cost-sensitive file-storage option. Huawei describes its principal advantages as large capacity, high bandwidth, and low cost, making it particularly appropriate for media processing, large-scale file sharing, HPC, and backup workloads.

The performance characteristics also support A and B. Huawei's documented SFS Capacity-Oriented implementation provides substantially greater maximum aggregate bandwidth than the previous-generation SFS Turbo Standard class. However, its access latency is approximately 3--20 ms, whereas SFS Turbo Standard provides lower latency, historically around 2--5 ms. SFS Turbo is therefore more appropriate where low-latency access and workloads involving large numbers of small files are important.

Capacity-Oriented storage can scale to petabyte-scale capacities and is specifically optimized economically for large-volume storage. Consequently, for equivalent expenditure, it can provide significantly greater capacity than performance-oriented SFS Turbo configurations.

Option D reverses this economic relationship. SFS Capacity-Oriented is not positioned as the more expensive alternative for equal capacity; low cost at large scale is one of its defining characteristics.

Answer : B

The statement is false because its description of infrastructure ownership does not correctly characterize a hybrid cloud. A hybrid cloud combines different cloud environments---most commonly private cloud and public cloud---and enables workloads, applications, or data to be distributed between them according to security, capacity, latency, compliance, or business requirements.

Huawei Cloud describes hybrid cloud as a blend of private and public cloud environments. The private portion may be dedicated to a particular customer and may host confidential or sensitive workloads, while public cloud resources are delivered through infrastructure operated by a cloud service provider. Consequently, the combined infrastructure is not inherently owned and operated by a single organization.

This ownership distinction separates hybrid cloud from a purely private-cloud model. A private cloud can be dedicated to a single organization, whereas hybrid architecture deliberately combines environments that may have different infrastructure ownership and operating responsibility.

The statement correctly recognizes that hybrid cloud is flexible and that workloads can use different cloud environments, but because it makes an absolute and incorrect assertion about single-organization ownership, the entire statement must be evaluated as FALSE.
