問題 #122
(Which of the following statements about static VXLAN tunnel configuration are true?Choose all that apply.)

A. An NVE interface can be associated with multiple VNIs. Therefore, you can create one NVE interface when there are multiple BDs.
B. On an NVE interface, the destination address of a VXLAN tunnel is specified based on the address in the ingress replication list. You can create one NVE interface for multiple VXLAN tunnels.
C. One NVE interface must be created for each VXLAN tunnel, and the source and destination IP addresses must be specified for the NVE interface. Therefore, the number of NVE interfaces is the same as the number of VXLAN tunnels on the VTEP.
D. One NVE interface must be created for each BD. If there are multiple BDs, multiple NVE interfaces must be created.

答案：A,B

解題說明：
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
In astatic VXLAN tunneldeployment, Huawei devices use anNVE (Network Virtualization Edge) interface as the logical tunnel interface for VXLAN encapsulation and decapsulation. The NVE interface represents the VTEP and does not have a one-to-one relationship with Bridge Domains (BDs) or VXLAN tunnels.
AnNVE interface can be associated with multiple VNIs, each corresponding to a different BD. Therefore, when multiple BDs exist on a VTEP,only one NVE interface is required, makingstatement B correctand statement A incorrect.
In static VXLAN, thedestination VTEP addressesare specified usingingress replication listsunder each VNI. This allows a single NVE interface to establishmultiple VXLAN tunnelsto different remote VTEPs. As a result, there is no requirement to create a separate NVE interface for each tunnel, makingstatement D correctandstatement C incorrect.
According to HCIP Datacom Campus Network VXLAN configuration principles, the correct practice is to createone NVE interface per VTEP, associate multiple VNIs with it, and define remote peers through ingress replication. Therefore, the correct answers areB and D.

問題 #123
In the WAN BGP protocol, if "route reflectors are configured between IBGP neighbors, and the reflectors reflect client routes to non-client neighbors", which of the following problems will be caused?

A. IBGP neighbor relationships are automatically disconnected.
B. May create IBGP routing loops (if non-client neighbors are not configured with loop prevention mechanisms).
C. The reflector automatically stops the route reflection function.
D. Non-client neighbors cannot receive reflected routes (the route reflector does not reflect client routes to non-clients).

答案：B

問題 #124
In an MPLS VPN network, when a PE device receives a VPNv4 route whose "RD (route identifier) does not match the local VPN instance RD", which of the following problems will occur?

A. The PE device refuses to receive the VPNv4 route.
B. The PE device redirects the route to the wrong VPN instance.
C. The route is successfully imported into the local VPN instance without affecting business operations.
D. The PE device automatically modifies the RD to the local instance RD and then receives the data.

答案：A

問題 #125
(Which of the following advantages are provided by Telemetry compared with SNMP?Choose all that apply.
)

A. Telemetry establishes sessions based on SSH, ensuring security.
B. Telemetry supports second-level data collection with higher precision.
C. Telemetry supports various data types based on the YANG model.
D. Telemetry configures and manages different databases of managed devices.

答案：B,C

解題說明：
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
Telemetry is a next-generation network data collection technology designed to overcome the limitations of traditional SNMP polling. One of its major advantages is that it ismodel-driven, relying onYANG modelsto define structured and extensible data formats. This allows Telemetry to support various data types and provides stronger semantic meaning than SNMP MIBs, makingoption A correct.
Another key advantage ishigh-frequency data collection. Telemetry supportssecond-level or even sub- second-level reporting, enabling more precise and real-time network monitoring. This capability is critical for intelligent O&M scenarios such as fault prediction, traffic analysis, and SLA assurance. SNMP, by contrast, typically relies on periodic polling with much lower precision. Therefore,option D is correct.
Telemetry does not establish sessions based on SSH. Instead, it typically uses protocols such asgRPCover secure transport channels like TLS. Hence,option B is incorrect.
Option C is also incorrect because Telemetry focuses ondata subscription and reporting, not on configuring or managing device databases. Configuration management remains the responsibility of controllers or network management systems, not the Telemetry mechanism itself.
According to HCIP Datacom Campus Network documentation, Telemetry's strengths lie in model- driven data representation and high-precision, real-time monitoring, making A and D the correct answers.

問題 #126
In Huawei's WAN solution, for the scenario of "high packet loss rate in WAN links causing intermittent VoIP voice calls", which of the following technologies can "achieve packet loss recovery through redundant data transmission and ensure smooth voice calls"?

A. Packet loss recovery technology based on forward error correction (FEC) (send redundant data, and the receiving end recovers the lost packets).
B. Ignoring packet loss and taking no action results in poor voice quality.
C. Relying solely on TCP retransmission mechanisms to recover lost packet data.
D. Reduce the VoIP voice sampling rate to decrease the amount of data.

答案：A

問題 #127
