Huawei HCIP-Data Center Network V1.0 Sample Questions (Q14-Q19):

NEW QUESTION # 14
In the DCN architecture, spine nodes connect various network devices to the VXLAN network.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
In Huawei's Data Center Network (DCN) architecture, particularly with the CloudFabric solution, the spine-leaf topology is a common design for scalable and efficient data centers. VXLAN (Virtual Extensible LAN) is used to create overlay networks, enabling large-scale multi-tenancy and flexible workload placement.
Spine Nodes' Role: In this architecture, spine nodes act as the backbone, interconnecting leaf nodes (which connect to servers, storage, or other endpoints) and facilitating high-speed, non-blocking communication. Spine nodes typically handle Layer 3 routing and serve as VXLAN tunnel endpoints (VTEPs) or connect to devices that do, integrating the physical underlay with the VXLAN overlay network.
Connection to VXLAN: Spine nodes ensure that traffic from various network devices (via leaf nodes) is routed efficiently across the VXLAN fabric. They provide the high-bandwidth, low-latency backbone required for east-west traffic in modern data centers, supporting VXLAN encapsulation and decapsulation indirectly or directly depending on the deployment.
Thus, the statement is TRUE (A) because spine nodes play a critical role in connecting the underlay network (various devices via leaf nodes) to the VXLAN overlay, as per Huawei's DCN design principles.


NEW QUESTION # 15
Which of the following technologies are Layer 4 load balancing technologies? (Select All that Apply)

  • A. Nginx
  • B. LVS
  • C. HAProxy
  • D. PPP

Answer: A,B,C

Explanation:
Layer 4 load balancing operates at the transport layer (OSI Layer 4), using TCP/UDP protocols to distribute traffic based on information like IP addresses and port numbers, without inspecting the application-layer content (Layer 7). Let's evaluate each option:
A . Nginx: Nginx is a versatile web server and reverse proxy that supports both Layer 4 and Layer 7 load balancing. In its Layer 4 mode (e.g., with the stream module), it balances TCP/UDP traffic, making it a Layer 4 load balancing technology. This is widely used in Huawei's CloudFabric DCN solutions for traffic distribution. TRUE.
B . PPP (Point-to-Point Protocol): PPP is a Layer 2 protocol used for establishing direct connections between two nodes, typically in WAN scenarios (e.g., dial-up or VPNs). It does not perform load balancing at Layer 4 or any layer, as it's a point-to-point encapsulation protocol. FALSE.
C . LVS (Linux Virtual Server): LVS is a high-performance, open-source load balancing solution integrated into the Linux kernel. It operates at Layer 4, using techniques like NAT, IP tunneling, or direct routing to distribute TCP/UDP traffic across backend servers. It's a core Layer 4 technology in enterprise DCNs. TRUE.
D . HAProxy: HAProxy is a high-availability load balancer that supports both Layer 4 (TCP mode) and Layer 7 (HTTP mode). In TCP mode, it balances traffic based on Layer 4 attributes, making it a Layer 4 load balancing technology. It's commonly deployed in Huawei DCN environments. TRUE.
Thus, A (Nginx), C (LVS), and D (HAProxy) are Layer 4 load balancing technologies. PPP is not.


NEW QUESTION # 16
In the CloudFabric Solution, SecoManager and iMaster NCE-Fabric are deployed independently. After SecoManager is installed, it needs to be manually interconnected with iMaster NCE-Fabric.

  • A. FALSE
  • B. TRUE

Answer: A

Explanation:
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.


NEW QUESTION # 17
Which of the following statements is false about centralized gateway deployment using BGP EVPN?

  • A. A VXLAN tunnel is identified by a pair of VTEP IP addresses and can be established if the local and remote VTEP IP addresses are reachable to each other at Layer 3.
  • B. When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD.
  • C. When BGP EVPN is used to dynamically establish a VXLAN tunnel, the local and remote VTEPs first establish a BGP EVPN peer relationship and then exchange BGP EVPN routes to transmit VNI and VTEP IP address information. A VXLAN tunnel is then dynamically established between them.
  • D. When configuring a VTEP, you need to create an EVPN Instance in the Layer 2 BD and configure an RD for the local EVPN instance. You do not need to configure an RT.

Answer: D

Explanation:
Centralized gateway deployment using BGP EVPN in Huawei's data center networks (e.g., CloudFabric) involves a gateway handling Layer 3 routing for VXLAN overlays. Let's evaluate each statement:
A . When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD: A Bridge Domain (BD) is a Layer 2 broadcast domain in VXLAN, and a Virtual Network Identifier (VNI) is bound to it to segment traffic. This is a standard step when configuring a VXLAN Tunnel Endpoint (VTEP) to map the overlay network. TRUE.
B . A VXLAN tunnel is identified by a pair of VTEP IP addresses and can be established if the local and remote VTEP IP addresses are reachable to each other at Layer 3: VXLAN tunnels are established between VTEPs using their IP addresses as endpoints. Layer 3 reachability (e.g., via underlay routing) is required for tunnel establishment. TRUE.
C . When BGP EVPN is used to dynamically establish a VXLAN tunnel, the local and remote VTEPs first establish a BGP EVPN peer relationship and then exchange BGP EVPN routes to transmit VNI and VTEP IP address information. A VXLAN tunnel is then dynamically established between them: In BGP EVPN, VTEPs establish a BGP peer relationship, exchange routes (e.g., Type 2 for MAC/IP or Type 3 for multicast), and share VNI and VTEP IP details, enabling dynamic tunnel setup. TRUE.
D . When configuring a VTEP, you need to create an EVPN Instance in the Layer 2 BD and configure an RD for the local EVPN instance. You do not need to configure an RT: An EVPN Instance (EVI) is created within a BD, and a Route Distinguisher (RD) is configured to make routes unique. However, Route Targets (RTs) are also required to control route import/export between EVPN peers, ensuring proper VNI and route distribution. Stating that RT configuration is not needed is incorrect, as RTs are essential for BGP EVPN operation. FALSE.
Thus, D is the false statement because RT configuration is necessary in centralized gateway deployment with BGP EVPN.


NEW QUESTION # 18
Which of the following protocols is used to back up session tables between the active and standby firewalls in the hot standby scenario?

  • A. HRP
  • B. BFD
  • C. M-LAG
  • D. VRRP

Answer: A

Explanation:
In a hot standby scenario, firewalls (e.g., Huawei USG series) maintain high availability by synchronizing session tables between active and standby devices to ensure seamless failover. Let's evaluate each protocol:
A . M-LAG (Multi-Chassis Link Aggregation): M-LAG is a link aggregation technology for switches, not designed for session table backup between firewalls. Incorrect.
B . VRRP (Virtual Router Redundancy Protocol): VRRP provides gateway redundancy by electing a master router, but it does not handle session table synchronization between firewalls. Incorrect.
C . BFD (Bidirectional Forwarding Detection): BFD is a fast failure detection protocol used with routing protocols, not for session table backup. Incorrect.
D . HRP (Hot Standby Redundancy Protocol): HRP is Huawei's proprietary protocol specifically designed for firewall hot standby scenarios. It synchronizes session tables, configuration data, and status information between active and standby firewalls to ensure stateful failover. Correct.
Thus, the answer is D (HRP).
