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

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).

Answer : A, C, D

Huawei's CloudFabric Solution supports various data center scenarios. Let's evaluate each option:

A . Container network: This is true. CloudFabric supports containerized environments (e.g., Kubernetes) with VXLAN and SDN integration. TRUE.

B . OpenFlow network: This is false. CloudFabric primarily uses BGP-EVPN and proprietary protocols, not OpenFlow, which is more associated with other SDN platforms. FALSE.

C . Hosting: This is true. CloudFabric is suitable for hosting environments, providing multi-tenant network services. TRUE.

D . Cloud-network integration: This is true. It integrates with cloud platforms (e.g., OpenStack) for unified management. TRUE.

E . Computing: This is false. While it supports computing resources, ''computing'' is not a primary scenario; it's an enabler (e.g., server connectivity). FALSE.

Thus, A, C, and D are application scenarios.

Answer : B, C

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.

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 : A

VXLAN is an overlay technology that encapsulates Layer 2 frames within UDP packets to create scalable virtual networks, widely used in Huawei's data center architectures. Let's evaluate each statement:

A . A VXLAN tunnel endpoint that performs encapsulation is called a VNI: This is incorrect. A VXLAN Tunnel Endpoint (VTEP) is the device (physical or virtual) that performs encapsulation and decapsulation. The VNI (VXLAN Network Identifier) is a 24-bit field in the VXLAN header that identifies the virtual network, not the endpoint. FALSE.

B . VXLAN uses ECMP of the underlay network to improve network forwarding performance: Equal-Cost Multi-Path (ECMP) routing in the underlay network allows VXLAN to distribute traffic across multiple paths, enhancing load balancing and performance. This is a standard feature in Huawei's VXLAN implementations. TRUE.

C . A VXLAN network is built based on UDP: VXLAN encapsulates Ethernet frames within UDP packets (using port 4789), making it a UDP-based overlay protocol. This is a core characteristic of VXLAN. TRUE.

D . VXLAN expands the number of subnets to 16 million and supports multi-tenancy: With a 24-bit VNI, VXLAN supports up to 16 million (2^24) unique network identifiers, enabling extensive subnet segmentation and multi-tenancy, a key advantage over traditional VLANs (4096 limit). TRUE.

Thus, A is the false statement because a VTEP, not a VNI, is the tunnel endpoint that performs encapsulation.

Answer : C, D

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.

Answer : A, B, C, D

Microsegmentation in Huawei's data center networks (e.g., CloudFabric with SDN) divides Endpoint Groups (EPGs) to enforce fine-grained security policies. EPGs group endpoints (e.g., VMs) based on attributes. Let's evaluate each option:

A . Operating system: This is true. The OS type (e.g., Linux, Windows) can be used to segment EPGs, enabling policy enforcement based on OS-specific security needs. TRUE.

B . VM name: This is true. VM names can be used as identifiers for microsegmentation, allowing policies to target specific VMs. TRUE.

C . IP address: This is true. IP addresses are commonly used to define EPG boundaries, especially for network-based segmentation. TRUE.

D . MAC address: This is true. MAC addresses can segment EPGs, particularly for Layer 2-based policies or device-specific isolation. TRUE.

All options A, B, C, and D are valid conditions for microsegmentation to divide EPGs in Huawei's implementation.
