Huawei H12-893_V1.0 Exam Questions

iMaster NCE-FabricInsight is Huawei's network assurance and analytics tool, integrated with CloudFabric, that uses telemetry to monitor network health. The health function identifies various issues. Let's evaluate each option:

A . Switch ARP entry threshold exceeded: This is true. FabricInsight monitors ARP table usage and can detect when the threshold is exceeded, indicating potential resource issues. TRUE.

B . OSPF router ID conflict: This is true. FabricInsight can detect OSPF router ID conflicts, which cause routing instability, through health checks on control plane data. TRUE.

C . Switch CPU usage threshold exceeded: This is true. FabricInsight tracks device performance metrics, including CPU usage, and flags thresholds to prevent performance degradation. TRUE.

D . Routing loop on the network: This is true. FabricInsight analyzes traffic patterns and routing tables to identify loops, leveraging telemetry data for network-wide health assessment. TRUE.

All options A, B, C, and D can be identified by the health function of iMaster NCE-FabricInsight.

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, is VRM.

In Huawei's CloudFabric Solution, Virtual Private Clouds (VPCs) enable isolated network environments, and interworking scenarios involve traffic between VPCs. The statement claims that traffic is checked and filtered only by the firewall in the source or destination VPC. Let's evaluate:

VPC Interworking: Traffic between VPCs can be routed via a gateway (e.g., a Layer 3 gateway or centralized router) and may involve multiple security checkpoints depending on the design. Firewalls can be deployed in the source VPC, destination VPC, or a centralized location (e.g., a service chain or border gateway).

Firewall Role: The statement implies exclusivity (only one firewall), but in practice, traffic may be filtered by firewalls at both ends, a centralized firewall, or additional security devices (e.g., VAS nodes) in the path. For example, inter-VPC traffic might pass through a firewall in the source VPC for egress filtering and another in the destination VPC for ingress filtering, or a shared firewall in a hub-and-spoke model. Huawei's security architecture (e.g., with SecoManager) supports distributed or centralized filtering, not limited to a single VPC's firewall.

The statement is FALSE (B) because traffic is not restricted to being checked and filtered only by the firewall in the source or destination VPC; multiple firewalls or security devices may be involved.

Huawei's iMaster NCE-Fabric is an SDN controller for the CloudFabric Solution, providing network orchestration and management. It includes built-in servers to support its operations. Let's evaluate each option:

A . DNS server: This is false. iMaster NCE-Fabric does not include a built-in DNS server; it relies on external DNS services for name resolution, configured during deployment. FALSE.

B . RADIUS authentication server: This is false. RADIUS authentication is typically handled by external AAA servers; iMaster NCE-Fabric integrates with them but does not embed a RADIUS server. FALSE.

C . DHCP server: This is true. iMaster NCE-Fabric includes a built-in DHCP server to assign temporary IP addresses during Zero Touch Provisioning (ZTP) or initial device configuration. TRUE.

D . Version file server: This is true. A version file server is built into iMaster NCE-Fabric to store and deliver software images or configuration files for device upgrades and management. TRUE.

Thus, C (DHCP server) and D (Version file server) are built into iMaster NCE-Fabric.

The Easy mode in Huawei's iMaster NCE-Fabric simplifies VXLAN fabric deployment with automated configuration. Certain pre-deployment steps are required. Let's evaluate each option:

A . Disable data synchronization upon going online for the first time: This is false. Data synchronization is typically enabled by default to ensure consistency; disabling it is not a standard pre-deployment step and is optional based on specific needs. FALSE.

B . Load the license: This is true. A valid license must be loaded into iMaster NCE-Fabric before deployment to unlock features, including Easy mode functionality. TRUE.

C . Pre-configure the access ports: This is true. Access ports on devices (e.g., server leaf nodes) need to be pre-configured (e.g., with VLANs or basic settings) to ensure connectivity before Easy mode automation begins. TRUE.

D . Configure an SSH fingerprint verification policy: This is false. SSH fingerprint verification is part of security configuration but is not a mandatory pre-deployment step for Easy mode; it can be set post-deployment or is automated. FALSE.

Thus, B (Load the license) and C (Pre-configure the access ports) are required operations before deployment in Easy mode.
