Huawei Updated H13-811_V3.5 Exam Questions and Answers by nahla

The statement is TRUE . Huawei Cloud makes an explicit architectural distinction between Elastic Cloud Servers and Bare Metal Servers regarding the underlying compute resources. An ECS is a virtualized compute instance. Multiple ECS instances can therefore consume resources provided by the same underlying physical host, with virtualization providing logical isolation between tenants and workloads.

A BMS, by contrast, provides exclusive access to physical compute resources. Huawei Cloud states directly that BMS users can exclusively access physical resources, whereas ECS users share those physical resources. This makes BMS particularly suitable for mission-critical systems, big-data clusters, enterprise middleware, high-performance workloads, and applications that require predictable performance or direct access to physical CPU and memory resources.

Huawei's BMS comparison also identifies Exclusive resources = Yes for BMS and traditional physical servers, but No for ECS. BMS additionally provides cloud characteristics such as automatic provisioning, VPC integration, image-based deployment, monitoring, and cloud storage while retaining physical-server performance.

Therefore, the differentiation presented in the question is technically accurate.

===============

1 → Bare Metal Server (BMS)

2 → Elastic Cloud Server (ECS)

3 → Physical server

The first scenario maps to BMS because Bare Metal Servers combine exclusive access to physical resources with cloud-oriented provisioning and management. Huawei Cloud recommends BMS for key or mission-critical applications and services requiring high performance. BMS retains direct physical CPU and memory access while supporting capabilities such as automatic provisioning, VPC networking, image deployment, monitoring, and cloud storage. It therefore provides both resource exclusivity and cloud flexibility .

The second scenario maps to ECS . ECS instances operate on virtualized infrastructure, so physical server resources can be shared among virtual machines. This model is appropriate for general-purpose and specialized cloud workloads where virtualization, rapid deployment, elasticity, and efficient resource utilization are priorities.

The third scenario maps to a traditional physical server . A physical server also provides exclusive resources, but Huawei's comparison shows that traditional servers do not inherently provide cloud capabilities such as automatic provisioning, VPC integration, image-based deployment, and standardized cloud monitoring. This makes them characteristic of traditional dedicated-service environments.

Huawei's comparison explicitly records exclusive resources for BMS and physical servers, but not ECS.

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 .
