Huawei's anti-DDoS solution can be deployed in multiple scenarios. Which of the following are anti-DDoS deployment scenarios? (Select all that Apply)
A. In-line deployment
B. Off-path deployment and static traffic diversion
C. Per-packet inspection and dynamic traffic diversion
D. Flow inspection and dynamic traffic diversion
答案：A,B,D
解題說明：
Huawei's anti-DDoS solution supportsmultiple deployment scenariosdepending on the network design and customer needs:
A: Flow inspection and dynamic traffic diversion: Monitors traffic flows and dynamically redirects suspicious traffic to the cleaning center.
B: In-line deployment: Anti-DDoS device sits directly in the data path, filtering traffic in real time.
C: Off-path deployment and static traffic diversion: Traffic is redirected to scrubbing centers using fixed rules.
D: Per-packet inspection and dynamic traffic diversionisnot a standard Huawei anti-DDoS deployment term, and Huawei's solution focuses onflow-level inspection, not deep per-packet analysis in this context.

問題 #82
VXLAN uses MAC-in-UDP encapsulation to extend Layer 2 networks. It encapsulates Ethernet frames into IP packets for routing, without considering the MAC addresses of VMs. In addition, routed networks are not limited by the network architecture and support large-scale scalability. VM migration through routed networks is also not limited by the network architecture.
A. False
B. True
答案：B
解題說明：
VXLAN (Virtual Extensible LAN) technology uses MAC-in-UDP encapsulation to extend Layer 2 networks over Layer 3 networks.
It encapsulates the original Ethernet frame into a UDP packet, allowing it to traverse an IP network.
VXLAN decouples the logical network from the underlying physical network, meaning MAC addresses of VMs are encapsulated and do not affect the routing of packets across the IP underlay.
VXLAN supports large-scale network expansion with up to 16 million VXLAN segments (compared to 4096 VLANs).
Furthermore, because VXLAN uses a routed underlay network, VM migration is not restricted by Layer 2 boundaries.

問題 #83
The energy industry is one of the key industries that Huawei's WAN solution focuses on. Which of the following is not a highlight of Huawei's WAN solution for electric power?
A. SDN-based automatic OSM
O Jitter < 10 us
B. SRv6-based intelligent traffic steering: intelligent traffic steering based on delay and bandwidth
C. MACsec encryption
D. 10G FlexE, industry-leading low delay
答案：C
解題說明：
Huawei'sWAN solution for the energy/electric power industryfocuses onultra-low latency, high security, and intelligent O&M, with highlights including:
A: SRv6-based intelligent traffic steering
C: 10G FlexE, which ensuresindustry-leading low delay
D: SDN-based automatic O&M, enabling minute-level service provisioning and jitter control (e.g.,<10 #sjitter) MACsec encryption (B)is not listed as a specific highlight of the WAN solution for electric power, though it may be used in security-focused sectors. Instead,Huawei promotes IPsec and deterministic IP technologies for power industry WANs.

問題 #85
Which of the following technologies implements inter-device link aggregation, and can be used to build an active-active system to provide traffic load balancing and backup protection?
A. M-LAG
B. Eth-Trunk
C. LLDP
D. Stack
答案：A
解題說明：
M-LAG (Multi-Chassis Link Aggregation Group) is a technology that implements link aggregation across two or more independent physical devices (i.e., switches).
It enables downstream devices (such as servers or switches) to connect to two upstream devices as if they were one logical device.
This allows for:
Active-active forwarding (traffic load balancing)
Device-level redundancy (if one upstream device fails, the other continues forwarding traffic) Eth-Trunk refers to link aggregation but generally within a single device.
Stack creates a logical switch from multiple physical switches, but it does not address inter-device aggregation in the same distributed manner as M-LAG.
LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol for device discovery and has no role in link aggregation.
