질문 # 122
Which of the following can be used to transmit traffic to a VXLAN network and implement intra-subnet communication on the same VXLAN network?

A. Layer 3 VXLAN gateway
B. NVE interface
C. Layer 2 VXLAN gateway
D. VLANIF interface

정답：B

설명：
Comprehensive and Detailed In-Depth Explanation:
AnNVE (Network Virtualization Edge) interfaceis responsible for connecting physical or virtual devices to a VXLAN network. It functions as theVTEP (VXLAN Tunnel Endpoint)and supportsencapsulation and decapsulation of VXLAN packets.
Layer 2 VXLAN gateway (D)is used for intra-subnet communication, but theNVE interfaceis the actual point where traffic enters the VXLAN network.
Layer 3 VXLAN gateway (A)is used for inter-subnet communication.
VLANIF interface (C)is used for VLAN-based communication, not directly for VXLAN.
Therefore, theNVE interface (B)is the correct answer as it serves as thetraffic ingress and egress point for the VXLAN network.

질문 # 123
As shown in the figure, PC1 and PC2 are hosts that belong to the same network segment, below about between PC1 and PC2 What are the correct descriptions of IPv6 neighbor states?

A. If the MAC address information of PC2 can be queried on PC1, the neighbor relationship must be Reachable
B. If pc2's MAC address information can be queried on PC1, the neighbor relationship may be Probe
C. There are five possible neighbor states between PC1 and PC2: Incomplete, Reachable, and Stale , Delay, Probe
D. If the MAC address information of PC2 can be queried on PC1, the neighbor relationship may be Stale

정답：C,D

질문 # 124
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, run the command on the VTEP to view BGP EVPN routes. The route entries shown in the following figure are displayed. Which of the following statements about these routing entries are correct?
Network (EthTagId/IP Prefix/IP PrefixLen)
NextHop
*>i 0:172.16.2.0:24 1.1.1.2
*>i 0:172.16.13.0:24 1.1.1.2
*>i 0:192.168.122.0:30 1.1.1.2

A. These routes are Type 5 routes and carry network segment or mask information.
B. These routes carry the L2VNI.
C. These routes are Type 2 routes and carry host IP addresses.
D. These routes carry the L3VNI.

정답：A,D

설명：
Understanding BGP EVPN Route Types for VXLAN
# BGP EVPN (Ethernet VPN) is used for VXLAN control-plane learning.
# EVPN Type 2 Route (MAC/IP Advertisement)
* Carries: MAC + Host IP
* Used for: L2 forwarding, Host Mobility
# EVPN Type 5 Route (IP Prefix Advertisement)
* Carries: Network segment (Subnet) + Prefix
* Used for: VXLAN L3 routing
# What Do the Given Route Entries Show?
* 0:172.16.2.0/24
* 0:172.16.13.0/24
* 0:192.168.122.0/30
# These are IPv4 Subnets, NOT individual MACs.# Since they carry IP Prefixes, they belong to EVPN Type 5.
Analysis of the Answer Choices:
# A. These routes are Type 5 routes and carry network segment or mask information.
* Correct: The displayed routes carry network prefixes, which belong to EVPN Type 5.
# B. These routes are Type 2 routes and carry host IP addresses.
* Incorrect: Type 2 routes carry MAC + Host IP, NOT full subnets.
# C. These routes carry the L2VNI.
* Incorrect: L2VNI is for Layer 2 VXLAN bridging, but these are IP Prefix Routes (L3 routing).
# D. These routes carry the L3VNI.
* Correct: Type 5 routes are used for VXLAN L3 routing, which means they belong to L3VNI.
Real-World Application:
* VXLAN L3 Gateways: Type 5 routes enable distributed routing between VXLAN segments.
* Data Center Networks: Used to interconnect virtual machines (VMs) across different subnets.

질문 # 125
Which of the following roles is NOT a core role in Huawei's Free Mobility solution?

A. Authentication device
B. Policy enforcement device
C. Policy control device
D. iMaster NCE-Campus

정답：A

설명：
Understanding Huawei's Free Mobility Solution
Huawei's Free Mobility solution is designed to ensure that users can seamlessly access the network regardless of their physical location while maintaining consistent policies.
🔹 Key Components in Free Mobility Solution:
1️⃣ iMaster NCE-Campus (Answer A - Core Role)
Manages network policies & user access.
Implements centralized policy control & orchestration.
2️⃣ Policy Enforcement Device (Answer B - Core Role)
Ensures that user policies (such as QoS, security, VLANs) are applied dynamically.
Typically a switch or gateway enforcing access control.
3️⃣ Policy Control Device (Answer D - Core Role)
Stores and dynamically assigns policies based on user role & device type.
Works closely with iMaster NCE-Campus.
🔹 Why is C (Authentication Device) NOT a Core Role?
❌ Authentication devices (such as a RADIUS or AAA server) are not a core component of Huawei's Free Mobility solution.
They are part of the broader network security framework but not mandatory for Free Mobility.
Real-World Application:
Used in enterprise & campus networks where employees, guests, and IoT devices need seamless access while maintaining security policies.
✅ Reference: Huawei HCIE-Datacom Guide - Free Mobility Architecture & Policy Management

질문 # 126
Which of the following options is correct?

A. Unicast and broadcasting cannot effectively achieve data transmission between one source and multiple destinations on P2MP, but multicast technology can
B. Multicast technology is able to reduce redundant traffic, so network bandwidth can be saved C.
Multicast technology is used for "-to-many" applications
C. Since multicast is based on TCP to establish a connection, multicast technology can ensure the reliable transmission of data

정답：B,C
