H12-893_V1.0 Practice Exam Questions and Answers

In Huawei’s CloudFabric Solution, the iMaster NCE-Fabric controller manages the network in computing scenarios (e.g., virtualized environments). Controller interconnection with external systems can be mandatory or optional depending on functionality. Let’s evaluate each option:

A.  

Interconnection with FabricInsight:This is optional. FabricInsight is an analytics and assurance tool that enhances visibility and troubleshooting but is not required for basiccontroller operations in the computing scenario.OPTIONAL.

B.  

Interconnection with the authentication server:This is mandatory. Authentication servers (e.g., RADIUS, TACACS+) are essential for securing access to the controller and managed devices, a core requirement in computing scenarios.NOT OPTIONAL.

C.  

Interconnection with eSight:This is optional. eSight is a network management platform that provides additional monitoring and management capabilities, but it is not necessary for core controller functionality.OPTIONAL.

D.  

Interconnection with the VMM (Virtual Machine Manager):This is mandatory. Interconnection with a VMM (e.g., FusionCompute, OpenStack) is required to manage virtualized computing resources and orchestrate network services in the computing scenario.NOT OPTIONAL.

Thus,A (Interconnection with FabricInsight) and C (Interconnection with eSight)are optional services for controller interconnection.References:Huawei CloudFabric Data Center Network Solution – Controller Integration; HCIP-Data Center Network Training – Computing Scenario.

FusionCompute is Huawei’s virtualization platform, part of the FusionSphere ecosystem, designed for managing virtualized resources in data centers. Its logical architecture consists of two primary modules:

VRM (Virtualization Resource Management):VRM is the management module responsible for centralized control, resource allocation, and monitoring of virtual machines, hosts, and clusters. It provides the user interface and orchestration capabilities for administrators to manage the virtualized environment.

CNA (Compute Node Agent):CNA runs on physical hosts and handles the execution of virtualization tasks, such as VM creation, resource scheduling, and communication with the underlying hypervisor (typically KVM in Huawei’s implementation). It acts as the compute node agent interfacing with the hardware.

Together, VRM and CNA form the core logical architecture of FusionCompute, with VRM managing the environment and CNA executing the compute tasks. The answer, per Huawei’s documentation, isVRM.References:Huawei FusionCompute Product Documentation – Architecture Overview; HCIP-Data Center Network Training – FusionCompute Section.
