Which of the following is not a feature of Huawei's Mini-BNG solution?
A. Limited functions
B. Independent deployment
C. Small footprint
D. Lower power consumption
正解：A
解説：
Huawei'sMini-BNG (Broadband Network Gateway)solution is designed forsmall/medium-scale deploymentscenarios and offers:
Small footprint(1U/2U chassis)
Independent deployment, with flexibility for edge networks
Low power consumption, making it cost-effective for remote PoPs
However, itdoes not have limited functions. Despite its compact size, it supportscomprehensive BNG capabilitiessuch as user management, IP address allocation, QoS, and security features - makingOption C (Limited functions) incorrect.

Which of the following are the highlights of Huawei CloudEngine S16700 series switches? (Select all that apply)
A. Ultra-high reliability: dual-input power supply
B. Ultra-large capacity: 4.8 Tbps per slot, scalable to 14.4 Tbps in the future
C. All-new architecture: backplane-free orthogonal architecture, improving switching capacity by 50%
D. M-LAG for zero service interruptions during upgrade
正解：B、C、D
解説：
Huawei CloudEngine S16700 is a next-gen modular core switch for large campus networks. Its key features include:
Ultra-large capacity: Each slot supports up to 4.8 Tbps throughput and can be scaled up to 14.4 Tbps (Option A - True) Backplane-free orthogonal architecture: Significantly enhances switching efficiency and simplifies cooling (Option B - True) M-LAG support: Enables in-service software upgrades and link-level redundancy (Option D - True) However, while dual-input power supplies are standard, this alone is not highlighted as an "ultra-high reliability" feature in Huawei documentation (Option C - Not a core highlight).

Which of the following technologies can improve the reliability of firewalls?
A. Security
B. NAT HRP
C. policies
D. VLAN
正解：B
解説：
NAT HRP (Hot Standby High Reliability Protocol)is used in Huawei firewalls to synchronizeNAT sessions and state informationbetween theactive and standby firewalls. This enablesseamless failoverwithout session interruption, thereby improving thereliabilityof the firewall deployment.
A: VLANis used for logical segmentation
B: Securityis a broad concept, not a specific technology
C: Policiesgovern traffic handling but don't impact hardware reliability directly Reference:

質問 # 86
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. LLDP
B. Stack
C. Eth-Trunk
D. M-LAG
正解：D
解説：
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.
