Huawei H12-893_V1.0 Exam - Topic 5 Question 16 Discussion

Actual exam question for Huawei's H12-893_V1.0 exam

Question #: 16
Topic #: 5

Which of the following components is not required to provide necessary computing, storage, and network resources for VMs during VM creation?

ANova

BNeutron

CCeilometer

DCinder

Show Suggested Answer

Suggested Answer: C

This question pertains to OpenStack, a common virtualization platform in Huawei's HCIP-Data Center Network curriculum, where components collaborate to create and manage virtual machines (VMs). Let's analyze each component's role in providing computing, storage, and network resources during VM creation:

A . Nova: Nova is the compute service in OpenStack, responsible for managing VM lifecycles, including provisioning CPU and memory resources. It's essential for providing computing resources during VM creation. Required.

B . Neutron: Neutron is the networking service, handling virtual network creation, IP allocation, and connectivity (e.g., VXLAN or VLAN) for VMs. It's critical for providing network resources during VM creation. Required.

C . Ceilometer: Ceilometer is the telemetry service, used for monitoring, metering, and collecting usage data (e.g., CPU utilization, disk I/O) of VMs. While useful for billing or optimization, it does not directly provide computing, storage, or network resources during VM creation. Not Required.

D . Cinder: Cinder is the block storage service, providing persistent storage volumes for VMs (e.g., for OS disks or data). It's essential for providing storage resources during VM creation if a volume is attached. Required.

Thus, C (Ceilometer) is not required to provision the core resources (computing, storage, network) for VM creation, as its role is monitoring, not resource allocation.
