Huawei HCIP-Data Center Network V1.0 Sample Questions (Q37-Q42):

NEW QUESTION # 37
Assume that a VXLAN tunnel is monitored on a Huawei CE series switch and that the tunnel status is Down or the tunnel fails to be dynamically established. In this scenario, which of the following statements are true about how to check the cause of the fault? (Select All that Apply)

  • A. Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel.
  • B. Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel.
  • C. Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down.
  • D. Run the display vxlan statistics command to check the cause of the fault.

Answer: A,B,C,D

Explanation:
On Huawei CloudEngine (CE) series switches, VXLAN tunnel monitoring and troubleshooting involve specific commands to diagnose issues such as tunnel Down status or failed dynamic establishment. Let's evaluate each option:
A . Run the display vxlan statistics command to check the cause of the fault: This command provides statistics on VXLAN tunnel traffic, including packet drops, encapsulation/decapsulation counts, and errors. It helps identify issues like misconfiguration or network congestion, making it a valid troubleshooting tool. TRUE.
B . Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel: This command displays information about VXLAN peers, including their IP addresses, VNIs, and reachability status. Checking the peer device's status can reveal connectivity or configuration mismatches, aiding fault diagnosis. TRUE.
C . Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel: This command logs and displays troubleshooting details, including the latest five failure reasons for dynamic tunnel setup (e.g., BGP EVPN issues or reachability problems). This is a standard feature on Huawei CE switches. TRUE.
D . Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down: This command also tracks reasons for tunnel Down events (e.g., underlay failure, peer unreachability), limited to the latest five incidents. This is consistent with Huawei's troubleshooting capabilities. TRUE.
All options A, B, C, and D are true, as they represent valid commands and approaches to troubleshoot VXLAN tunnel issues on Huawei CE switches.


NEW QUESTION # 38
In the spine-leaf DCN architecture, the border leaf node and service leaf node can be deployed on the same device.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
In Huawei's spine-leaf data center network (DCN) architecture, the topology consists of spine nodes (core) and leaf nodes (access/aggregation). Leaf nodes can serve different roles:
Border Leaf Node: Connects the DCN to external networks or other domains, handling Layer 3 routing.
Service Leaf Node: Connects to internal services (e.g., servers, VMs), often handling Layer 2/Layer 3 traffic.
In practice, a single physical device can be configured to perform both roles (border and service) if it has the necessary interfaces and routing capabilities. Huawei's CloudFabric documentation supports this flexibility, allowing a leaf switch to act as both a border and service node based on configuration (e.g., using VRFs or VXLAN gateways). This reduces hardware costs and simplifies deployment in smaller DCNs.
The statement is TRUE (A) because the border leaf and service leaf roles can be deployed on the same device in a spine-leaf architecture.


NEW QUESTION # 39
Which of the following are the application scenarios of Huawei CloudFabric Solution? (Select All that Apply)

  • A. Hosting
  • B. Container network
  • C. Cloud-network integration
  • D. OpenFlow network
  • E. Computing

Answer: A,B,C


NEW QUESTION # 40
In network overlay, both endpoints of a VXLAN tunnel are physical switches.

  • A. TRUE
  • B. FALSE

Answer: B

Explanation:
In a network overlay, VXLAN (Virtual Extensible LAN) tunnels extend Layer 2 networks over a Layer 3 underlay, commonly implemented in Huawei's data center solutions. The endpoints of a VXLAN tunnel are VXLAN Tunnel Endpoints (VTEPs), which encapsulate and decapsulate traffic.
VTEP Roles: VTEPs can be physical switches (e.g., Huawei CloudEngine series), virtual switches (e.g., Open vSwitch on a hypervisor), or routers with VXLAN support. The endpoints are defined by their IP addresses, not their physical nature.
Deployment Flexibility: In modern data centers, VXLAN tunnels often connect physical switches to virtualized environments where VTEPs reside on hypervisors or servers hosting VMs. For example, a VM's vNIC might connect to a virtual switch (VTEP) that tunnels to a physical switch VTEP. Thus, both endpoints are not always physical switches; one or both can be virtual.
The statement is FALSE (B) because both endpoints of a VXLAN tunnel are not necessarily physical switches; they can include virtual VTEPs in hypervisors or other devices.


NEW QUESTION # 41
Which of the following is not included in the physical architecture of a server?

  • A. Hardware
  • B. OS
  • C. VMmonitor
  • D. Application

Answer: D

Explanation:
The physical architecture of a server refers to the tangible and low-level components that constitute the server itself, distinct from logical or software layers. Let's evaluate each option:
A . Application: Applications are software running on top of an operating system or virtual machine, not part of the server's physical architecture. They belong to the logical or user layer, not the physical structure. Not Included.
B . VMmonitor (Hypervisor): Assuming "VMmonitor" refers to a hypervisor (e.g., KVM or Xen), it's a software layer, but in Type-1 hypervisor scenarios, it runs directly on hardware, managing VMs. In Huawei's context, it's considered part of the server's operational architecture when deployed physically. Included.
C . OS (Operating System): The OS (e.g., Linux, Windows) runs directly on server hardware or within a VM. In bare-metal servers, it's a core component of the physical deployment. Included.
D . Hardware: Hardware (e.g., CPU, RAM, NICs, disks) is the foundational physical architecture of a server, providing the physical resources for all operations. Included.
Thus, A (Application) is not part of the physical architecture, as it's a higher-level software entity, not a physical component.
