問題 #283
The fields that represent priority in the VLAN (8021Q) data encapsulation are a total of 6 bits.
答案：B
問題 #284
Which of the following inter-AS MPLS L3VPN solutions needs ASBRs to transmit VPNv4 routes?
答案：D
解題說明：
Comprehensive and Detailed
Inter-AS MPLS L3VPN Option B requires ASBRs to exchange VPNv4 routes using eBGP with label information.
Analysis of Inter-AS VPN Solutions:
Option B uses eBGP to exchange labeled VPNv4 routes between ASBRs but does not require MPLS between ASBRs.
Option A does not exchange VPNv4 routes over ASBRs (uses IP routing instead).
Option C uses MP-BGP and requires full MPLS between ASBRs.
Since Option B requires ASBRs to exchange VPNv4 routes, the correct answer is B.

問題 #285
Which of the following channels are involved in the Huawei SD-WAN Solution?
答案：A,B,C,D
解題說明：
Comprehensive and Detailed In-Depth Explanation:
TheHuawei SD-WAN Solutioninvolves four types of channels to ensure smooth and efficient network operation:
Management Channel (A):Used for managing and monitoring SD-WAN devices. It facilitates communication between theiMaster NCE-Campus controllerand SD-WAN devices.
Control Channel (B):Responsible for transmittingcontrol plane informationsuch as routing updates and protocol control messages.
Data Channel (C):Carries actualuser data trafficover the SD-WAN network.
Orchestration Channel (D):Used forservice orchestration, configuration delivery, and policy management.
All four channels work together to provide comprehensive network management, data transmission, and service orchestration in an SD-WAN environment.
問題 #286

答案：A,C,D
問題 #287
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, which of the following fields is NOT carried in BGP EVPN Type 5 routes?
答案：B
解題說明：
Understanding BGP EVPN and VXLAN Routing
EVPN (Ethernet VPN) with VXLAN is used for data center networking and L3 VPN interconnection.
# BGP EVPN Route Types & Their Purpose
* Type 2: MAC/IP Advertisement Route (Carries MAC + IP)
* Type 3: Inclusive Multicast Route (Carries VTEP Multicast Information)
* Type 5: IP Prefix Route (Used for Layer 3 VXLAN Routing)
# What does Type 5 route contain?
* # Route Distinguisher (RD): Identifies a unique VPN instance.
* # GW IP Address: Specifies the Gateway IP for L3 VXLAN routing.
* # IP Prefix Length: Defines the IPv4/IPv6 network mask for routing.
* # MAC Address is NOT included in Type 5
Why is Option B (MAC Address) Correct?
# MAC addresses are carried in EVPN Type 2 routes, NOT in Type 5.# Type 5 routes focus on IP prefixes, not MAC forwarding.
# Real-World Application:
* VXLAN L3 Gateways (EVPN Type 5) allow routers to forward IP traffic across VXLAN tunnels, removing the need for traditional L3 VPNs.
