Huawei HCIP-Data Center Network V1.0 Sample Questions (Q61-Q66):

NEW QUESTION # 61
Which of the following issues can be identified by the health function of iMaster NCE-FabricInsight? (Select All that Apply)

  • A. Switch ARP entry threshold exceeded
  • B. OSPF router ID conflict
  • C. Routing loop on the network
  • D. Switch CPU usage threshold exceeded

Answer: A,B,C,D

Explanation:
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.


NEW QUESTION # 62
BGP EVPN defines several types of BGP EVPN routes by extending BGP. Type ? routes are used to advertise host IP routes and external network routes. (Enter only digits.)

Answer:

Explanation:
5
Explanation:
BGP EVPN (Ethernet VPN) extends BGP to provide control plane functionality for VXLAN overlays, including in Huawei's data center networks. EVPN defines several route types to advertise different types of information:
Type 1: Auto-discovery routes for EVPN instances.
Type 2: MAC/IP Advertisement routes for host reachability.
Type 3: Inclusive Multicast Ethernet Tag routes for multicast traffic.
Type 4: Ethernet Segment routes for multi-homing.
Type 5: IP Prefix routes for advertising host IP routes and external network routes, enabling inter-subnet and external connectivity.
The question specifies routes used to advertise "host IP routes and external network routes," which aligns with Type 5 routes. These routes carry IP prefix information and a Layer 3 VNI, facilitating Layer 3 routing within the EVPN domain or to external networks. Thus, the answer is 5.


NEW QUESTION # 63
Which of the following statements is false about VM service traffic in the computing scenario?

  • A. Traffic between vSwitches on virtual servers and server leaf nodes is VLAN encapsulated.
  • B. Traffic inside a fabric is VXLAN encapsulated.
  • C. Traffic between VAS devices and service leaf nodes is VLAN encapsulated.
  • D. Inter-VPC traffic must pass through the firewall.

Answer: D

Explanation:
In Huawei's CloudFabric computing scenario, VM service traffic involves virtualized environments with VXLAN overlays and traditional VLANs. Let's evaluate each statement:
A . Traffic inside a fabric is VXLAN encapsulated: This is true. Within a CloudFabric network, VXLAN encapsulation is used to transport traffic across the fabric, enabling overlay networking for VMs. TRUE.
B . Inter-VPC traffic must pass through the firewall: This is false. Inter-VPC (Virtual Private Cloud) traffic can be routed directly between VPCs using a gateway or router (e.g., with EVPN Type 5 routes) without necessarily passing through a firewall, depending on security policies. Firewalls are optional for inter-VPC traffic, not mandatory. FALSE.
C . Traffic between VAS devices and service leaf nodes is VLAN encapsulated: This is true. Value-Added Services (VAS) devices (e.g., load balancers) often connect to service leaf nodes using VLAN encapsulation, especially in traditional or hybrid deployments. TRUE.
D . Traffic between vSwitches on virtual servers and server leaf nodes is VLAN encapsulated: This is true. Traffic from virtual switches (vSwitches) on hypervisors to physical server leaf nodes typically uses VLAN encapsulation over the physical NICs, before VXLAN overlay if applicable. TRUE.
Thus, B is the false statement because inter-VPC traffic does not always require a firewall.


NEW QUESTION # 64
In Huawei CloudFabric Solution, iMaster NCE-Fabric uses SNMP to collect alarms and logs of physical devices and vSwitches.

  • A. FALSE
  • B. TRUE

Answer: A

Explanation:
In Huawei's CloudFabric Solution, iMaster NCE-Fabric is the SDN controller responsible for managing physical devices and virtual switches (vSwitches). The method of data collection is critical for network monitoring.
SNMP Usage: Simple Network Management Protocol (SNMP) is a traditional method for collecting alarms and logs from network devices. However, Huawei's modern SDN controllers, including iMaster NCE-Fabric, primarily use telemetry (e.g., gRPC, NETCONF) for real-time data collection from physical devices and vSwitches. Telemetry provides higher efficiency and granularity compared to SNMP.
CloudFabric Approach: The solution leverages telemetry-based data collection, as documented in FabricInsight and iMaster NCE-Fabric guides, to gather alarms, logs, and performance metrics. SNMP may be supported as a legacy option but is not the primary method in this context.
The statement is FALSE (B) because iMaster NCE-Fabric predominantly uses telemetry, not SNMP, for collecting alarms and logs.


NEW QUESTION # 65
Which of the following statements is false about centralized gateway deployment using BGP EVPN?

  • A. 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.
  • B. When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD.
  • C. 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.
  • D. 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.

Answer: C

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.
