Huawei H12-893_V1.0 Exam Syllabus Topics:

Topic	Details
Topic 1	Technical Principles and Applications of Virtualization: This section assesses the skills of IT Solution Architects and Data Center Network Engineers in understanding server and network virtualization concepts, benefits, and implementation strategies within data centers. It also introduces Huawei’s FusionCompute platform, its features, functionalities, and applications in virtualization scenarios.
Topic 2	Data Center Network Technology and Application: This section evaluates the skills of IT Solution Architects and Data Center Network Engineers in understanding the fundamental concepts, evolution, and significance of data centers in modern enterprises. It delves into the overall architecture, including computing, storage, and networking components, and highlights typical application scenarios in sectors like finance, government, and large enterprises. Additionally, it introduces core concepts of data center networking (DCN), focusing on the Spine-Leaf architecture, and provides an overview of essential data center technologies such as VXLAN-based network layers, Underlay and Overlay networks, integrated cabling designs (ToR, EoR, MoR), equipment room modules, and the role of iMaster NCE in managing network devices.
Topic 3	Technical Principles and Applications of VXLAN: Aimed at Data Center Network Engineers, this section evaluates their understanding of the necessity, development, and foundational concepts of VXLAN technology in addressing traditional network limitations. It also delves into the principles of Ethernet VPN (EVPN) as a control plane for VXLAN and presents practical VXLAN deployment examples in common data center scenarios.
Topic 4	Data Center Network O&M: Aimed at Data Center Network Engineers, this section evaluates their understanding of operation and maintenance (O&M) challenges in data center networks. It introduces Huawei’s intelligent O&M solutions, including iMaster NCE-Fabric and iMaster NCE-FabricInsight, and discusses typical O&M scenarios, management, monitoring, troubleshooting practices, and automated O&M strategies through network service programmability.

Q42. Which of the following statements is false about the routing design for the underlay network during DCN deployment?

OSPF is recommended for small and midsize DCNs, and EBGP is recommended for large and midsize networks.

When OSPF is used on the underlay network, only single-area OSPF can be deployed.

Compared with OSPF, EBGP involves fewer calculations and offers better scalability.

When EBGP is used on the underlay network, each group of active-active leaf nodes is deployed in an AS.

Q43. An administrator configures BGP EVPN on all spine and leaf switches. The underlay network already provides IP connectivity. Which protocol is mainly responsible for carrying VXLAN overlay control-plane information between VTEPs?

OSPF

IS-IS

MP-BGP EVPN

VRRP

Q44. Which of the following statements is false about VXLAN tunnel establishment?

A VXLAN tunnel is identified by a pair of VTEPs.

After a tunnel is established, if one end of the tunnel goes Down, the other end may not go Down.

For a static tunnel, you need to manually configure the local and remote VNIs.

Dynamic tunnels depend on EVPN Type 5 routes to transmit information.

Q45. An engineer must isolate broadcast domains while allowing multiple tenants to share the same physical infrastructure. Which combination best fulfills both Layer 2 isolation and scalable overlay deployment?

VLAN + STP

VXLAN + VNI

LACP + VRRP

MPLS + NAT

Q46. Which of the following nodes connects computing resources such as virtual and physical servers to a VXLAN fabric?

DCI leaf

Server leaf

Border leaf

Service leaf

Q47. Which of the following statements are true about common storage types used by enterprises?

FTP servers are typically used for file storage.

Object storage devices are typically disk arrays.

Block storage applies to databases that require high I/O.

Block storage typically applies to remote backup storage.

Q48. The figure shows an incomplete VXLAN packet format.

Which of the following positions should the VXLAN header be inserted into so that the packet format is complete?

Q49. A tenant requires communication only within its own virtual network despite sharing the same VXLAN infrastructure with multiple business units. Which identifier uniquely distinguishes VXLAN segments?

VLAN ID

VNI

Router ID

Area ID

Q50. Which of the following statements is false about M-LAG deployment?

Multi-level M-LAG must be configured based on V-STP.

Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2.

M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking.

In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops.

Q51. Which of the following technologies are open-source virtualization technologies? (Select All that Apply)

Hyper-V

Xen

FusionSphere

KVM

Q52. Which of the following statements are true about the Easy mode? (Select All that Apply)

This mode has low networking requirements.

iMaster NCE-Fabric automatically generates configuration script files.

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.

Layer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page.

Q53. Which of the following technologies are Layer 4 load balancing technologies? (Select All that Apply)

Nginx

PPP

LVS

HAProxy

Q54. Which of the following statements is false about M-LAG deployment?
