Huawei HCIE-Datacom V1.0 Sample Questions (Q69-Q74):

NEW QUESTION # 69
In addition to indicating priority, the DSCP value can also indicate the drop probability. Which of the following DSCP values is set with the highest drop probability?

A. AF10
B. AF43
C. AF11
D. AF12

Answer: B

Explanation:
Understanding DSCP & Assured Forwarding (AF) Classes
* DSCP (Differentiated Services Code Point) is used for QoS (Quality of Service) classification in IP packet headers.
* Assured Forwarding (AF) classes provide four traffic classes (AF1x, AF2x, AF3x, AF4x).
* Each AF class has three drop precedence levels (Low = 1, Medium = 2, High = 3).
A screenshot of a computer AI-generated content may be incorrect.

Analysis of Options:
* AF43 (Answer A) # Class 4, High Drop (Highest priority, highest drop probability) #
* AF10 (Answer B) # Class 1, Low Drop (Lowest priority, lowest drop probability) #
* AF12 (Answer C) # Class 1, Medium Drop Probability #
* AF11 (Answer D) # Class 1, Low Drop Probability #
Why AF43?
* Highest priority traffic within AF Class 4.
* Highest drop probability (x3) means packets are dropped first under congestion.
* Used for premium but non-essential services (e.g., bulk data transfer, backups).

NEW QUESTION # 70
As shown in the figure, ARP broadcast suppression is enabled on VTEP1 in BD 20 (VNI 200).
* VTEP1 learns ARP information about PC2 through BGP EVPN routes.
* When VTEP1 forwards the ARP request for PC1's MAC address to VTEP2,
* What is the destination MAC address of the inner data frame?

A. MAC A
B. MAC B
C. MAC D
D. MAC C

Answer: D

Explanation:
Understanding VXLAN and ARP Suppression in BGP EVPN
VXLAN (Virtual Extensible LAN) is used to extend Layer 2 networks over Layer 3 infrastructure.
* VXLAN uses VTEPs (VXLAN Tunnel Endpoints) to encapsulate and forward Layer 2 traffic.
* BGP EVPN (Ethernet VPN) is used for MAC/IP address learning and distribution across VXLAN networks.
How ARP Request Forwarding Works in This Scenario?
1## ARP Broadcast Suppression Enabled (VXLAN Optimized Forwarding)
* Since ARP broadcast suppression is enabled on VTEP1, the ARP request is not flooded.
* Instead, VTEP1 checks its EVPN learned database to find PC2's MAC address (MAC C).
2## VTEP1 Encapsulates the ARP Request
* VTEP1 encapsulates the ARP request in a VXLAN packet and sends it to VTEP2.
* The original ARP frame inside the VXLAN tunnel still has:
* Source MAC: MAC A (PC1's MAC)
* Destination MAC: MAC C (PC2's MAC, learned via EVPN)
3## VXLAN Outer Headers
* The outer VXLAN header uses:
* Source IP: 1.1.1.1 (VTEP1)
* Destination IP: 2.2.2.2 (VTEP2)
* VNI (VXLAN Network Identifier): 200 (BD 20)
4## VTEP2 Receives and Forwards the ARP Request
* VTEP2 decapsulates the VXLAN packet and forwards the original ARP request to PC2 (MAC C).
* This ensures that only the intended receiver (PC2) gets the ARP request, preventing unnecessary broadcast flooding.
Why the Answer is MAC C?
# B. MAC C is Correct
* The destination MAC of the inner data frame is PC2's MAC (MAC C).
* This is because VTEP1 forwards the ARP request directly to VTEP2, which then forwards it to PC2.
Why Other Answers Are Incorrect?
# A. MAC B (Incorrect)
* MAC B is VTEP1's MAC address, which is used in the outer VXLAN header, not in the inner Ethernet frame.
# C. MAC A (Incorrect)
* MAC A is the source MAC of the ARP request (PC1), not the destination.
# D. MAC D (Incorrect)
* MAC D is not mentioned in the topology, so it is irrelevant.
