Huawei HCIP-Data Center Network V1.0 Sample Questions (Q49-Q54):

NEW QUESTION # 49
Which of the following components is not required to provide necessary computing, storage, and network resources for VMs during VM creation?

  • A. Nova
  • B. Cinder
  • C. Ceilometer
  • D. Neutron

Answer: C

Explanation:
This question pertains to OpenStack, a common virtualization platform in Huawei's HCIP-Data Center Network curriculum, where components collaborate to create and manage virtual machines (VMs). Let's analyze each component's role in providing computing, storage, and network resources during VM creation:
A . Nova: Nova is the compute service in OpenStack, responsible for managing VM lifecycles, including provisioning CPU and memory resources. It's essential for providing computing resources during VM creation. Required.
B . Neutron: Neutron is the networking service, handling virtual network creation, IP allocation, and connectivity (e.g., VXLAN or VLAN) for VMs. It's critical for providing network resources during VM creation. Required.
C . Ceilometer: Ceilometer is the telemetry service, used for monitoring, metering, and collecting usage data (e.g., CPU utilization, disk I/O) of VMs. While useful for billing or optimization, it does not directly provide computing, storage, or network resources during VM creation. Not Required.
D . Cinder: Cinder is the block storage service, providing persistent storage volumes for VMs (e.g., for OS disks or data). It's essential for providing storage resources during VM creation if a volume is attached. Required.
Thus, C (Ceilometer) is not required to provision the core resources (computing, storage, network) for VM creation, as its role is monitoring, not resource allocation.


NEW QUESTION # 50
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 # 51
An enterprise builds a DC and deploys iMaster NCE-Fabric to automatically deliver network configurations. After the engineer manually deploys the underlay network and delivers overlay network configurations through iMaster NCE-Fabric, it is found that tenant hosts cannot access external networks. Which of the following is not a possible cause of this fault?

  • A. No firewall security policy is configured when host traffic passes through the firewall.
  • B. The MAC address of the NVE interface on the VXLAN network is not manually specified.
  • C. No return route is configured on the PE.
  • D. The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model.

Answer: B

Explanation:
In Huawei's CloudFabric Solution, iMaster NCE-Fabric automates overlay network (e.g., VXLAN) configuration, while the underlay network is manually deployed. Tenant hosts failing to access external networks indicate a connectivity issue, likely at the overlay-underlay boundary or security layer. Let's evaluate each option as a possible cause:
A . No return route is configured on the PE: This is a possible cause. The Provider Edge (PE) device (e.g., border leaf or router) must have a return route to the tenant's VXLAN network for external access. Without it, traffic from external networks cannot reach the DC. POSSIBLE CAUSE.
B . The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model: This is a possible cause. Some Huawei switch models (e.g., CE series) require a service loopback interface as the VTEP source IP. If omitted or misconfigured based on the model, external connectivity fails. POSSIBLE CAUSE.
C . No firewall security policy is configured when host traffic passes through the firewall: This is a possible cause. If a firewall is in the path (e.g., between tenant VPC and external network), a missing security policy (e.g., allowing outbound traffic) blocks access. POSSIBLE CAUSE.
D . The MAC address of the NVE interface on the VXLAN network is not manually specified: This is not a possible cause. The Network Virtualization Edge (NVE) interface in VXLAN does not require a manually specified MAC address; it uses the switch's system MAC or auto-generates one. iMaster NCE-Fabric typically handles this automatically, and manual specification is neither required nor a common fault point for external access issues. NOT A POSSIBLE CAUSE.
Thus, D is not a possible cause of the fault.


NEW QUESTION # 52
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 # 53
Which of the following nodes is a backbone node of a DC and provides high-speed IP forwarding?

  • A. DC1 leaf
  • B. Border leaf
  • C. Service leaf
  • D. Spine

Answer: D

Explanation:
In Huawei's spine-leaf DCN architecture, nodes have distinct roles:
A . Spine: The spine nodes form the backbone of the data center, providing high-speed IP forwarding between leaf nodes. They handle east-west traffic with non-blocking connectivity, making them the core backbone nodes. Correct.
B . DC1 leaf: This is not a standard node type; it may be a typo or misnomer. Leaf nodes connect to endpoints, not act as backbones. Incorrect.
C . Service leaf: Service leaf nodes connect to internal services (e.g., servers), not the backbone, focusing on access rather than high-speed forwarding. Incorrect.
D . Border leaf: Border leaf nodes connect to external networks, handling routing, not serving as the internal backbone. Incorrect.
Thus, the answer is A (Spine).
