Huawei H12-893_V1.0 HCIP-Data Center Network V1.0 Exam Practice Test

Answer : A, B, D

The Easy mode in Huawei's iMaster NCE-Fabric simplifies network deployment for basic VXLAN fabrics. Let's evaluate each statement:

A . This mode has low networking requirements: This is true. Easy mode is designed for simple topologies (e.g., small spine-leaf networks) with minimal configuration complexity. TRUE.

B . iMaster NCE-Fabric automatically generates configuration script files: This is true. Easy mode automates script generation based on user inputs, reducing manual effort. TRUE.

C . On iMaster NCE-Fabric, you need to manually create and configure fabric resource pools, managed devices, device groups, device roles, tenants, and VPCs one by one in the Configuration Wizard menu: This is false. Easy mode automates these tasks, minimizing manual configuration compared to advanced modes. FALSE.

D . Layer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page: This is true. Easy mode supports automated orchestration of L2 (e.g., BDs) and L3 (e.g., gateways) services within a VPC. TRUE.

Thus, A, B, and D are true statements about Easy mode.

Answer : A, C, D

Zero Touch Provisioning (ZTP) in Huawei's CloudFabric automates device setup using DHCP. Let's evaluate each option:

A . Default gateway address: This is true. DHCP can deliver the default gateway address to configure routing for the device. TRUE.

B . SFTP server address: This is false. SFTP server addresses are not standard DHCP options; they may be configured manually or via other protocols (e.g., TFTP for boot files). FALSE.

C . DNS server address: This is true. DHCP can provide DNS server addresses (Option 6) for name resolution during ZTP. TRUE.

D . Temporary management IP address: This is true. DHCP assigns temporary IPs (e.g., Option 50) for management during initial provisioning in ZTP. TRUE.

Thus, A, C, and D can be delivered by a DHCP server in ZTP.

Answer : A

In Huawei's CloudFabric Solution, the underlay network provides the physical infrastructure for VXLAN overlays. Both OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are supported routing protocols:

OSPF: Suitable for smaller to medium-sized DCNs, offering fast convergence and simplicity.

BGP: Preferred for large-scale DCNs, providing scalability and multi-tenancy support (e.g., EBGP for inter-AS or iBGP for intra-DC).

Huawei documentation confirms flexibility in choosing OSPF or BGP based on network size and requirements. The statement is TRUE (A).

Answer : B

In Huawei's CloudFabric Solution, SecoManager (Security Manager) and iMaster NCE-Fabric (Network Controller) are components of the SDN ecosystem. SecoManager handles security policy management, while iMaster NCE-Fabric manages network orchestration.

Deployment: These components can be deployed independently but are designed to integrate seamlessly. Huawei's architecture supports automated interconnection after installation, leveraging northbound/southbound APIs or pre-configured integration workflows.

Interconnection: Manual interconnection is not required post-installation; the system automates the process once both are deployed and configured within the same management domain (e.g., via IP addressing and authentication).

The statement is FALSE (B) because interconnection is automated, not manual.

Answer : A, B, C, D

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.

Answer : B, C, D

In Huawei's CloudFabric Solution, the iMaster NCE-Fabric SDN controller cluster separates network planes based on carried services to ensure scalability and security. Let's evaluate each option:

A . BGP microservice plane: This is not a standard plane in Huawei's SDN architecture. BGP is used in the underlay/overlay but not defined as a separate microservice plane for the controller. FALSE.

B . Southbound service plane: This is true. The southbound plane carries configuration and control data to network devices (e.g., via NETCONF, BGP-EVPN), a critical service plane in SDN. TRUE.

C . Northbound management plane: This is true. The northbound plane provides APIs for management applications and orchestration (e.g., OpenStack integration), handling service requests. TRUE.

D . Internal communication plane: This is true. This plane facilitates communication between controller cluster nodes for synchronization and high availability. TRUE.

Thus, B (Southbound service plane), C (Northbound management plane), and D (Internal communication plane) are the network planes divided based on carried services.

Answer : B

In Huawei's spine-leaf VXLAN fabric (e.g., CloudFabric), nodes have specific roles:

A . DCI leaf: Data Center Interconnect (DCI) leaf nodes connect different data centers, not internal computing resources. Incorrect.

B . Server leaf: Server leaf nodes connect computing resources (virtual servers via hypervisors, physical servers) to the VXLAN fabric, handling access traffic. This is the correct role for connecting servers. Correct.

C . Border leaf: Border leaf nodes connect the DCN to external networks, not internal computing resources. Incorrect.

D . Service leaf: Service leaf nodes connect to value-added services (e.g., firewalls), not directly to computing resources like servers. Incorrect.

Thus, the answer is B (Server leaf).
