HCIA-Cloud Service V3.5 H13-811_V3.5 Exam Questions with Experts Answers Updated Recently

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 .

The correct advantages are B, C, and D. Huawei Cloud EVS provides a range of disk specifications and performance classes so customers can select storage appropriate for different workloads and budgets. Huawei's EVS overview explicitly lists various disk types and high security/reliability among its principal benefits.

EVS is also easier to manage than traditional physical storage. Huawei documentation comparing EVS with traditional hard disks states that EVS disks provide higher reliability and I/O throughput and are easier to use. Cloud-based provisioning eliminates much of the physical installation, replacement, cabling, and capacity-management work associated with conventional disks.

Option A is incorrect. EVS is block storage intended for cloud servers and cannot be used independently. Huawei explicitly states that EVS disks must first be attached to a supported server and then initialized, partitioned, and formatted before applications can persist data on them.

High reliability derives from distributed storage and data-protection mechanisms, while the range of available disk classes enables workload-specific performance selection.

Therefore, various disk types, ease of use, and high reliability are advantages; independent use is not.
