1.A typical campus network consists of the terminal layer, access layer, aggregation layer, core layer,
egress zone, and O&M zone.
A. True
B. False
Answer: B
Explanation:
In the latest Huawei Xinghe Intelligent Campus (V2.0) architecture, the network is officially categorized
into a four-layer architecture: Terminal Layer, Network Layer (which includes Access, Aggregation, and
Core), Management Layer (iMaster NCE), and Application Layer. While the components mentioned
(Egress, O&M) are physical zones, the "Typical Architecture" definition in HCSP documentation
distinguishes between the layers of the infrastructure and the functional zones. Furthermore, in many
modern SDN-based designs (like the Xinghe solution), the aggregation layer is often optional or collapsed,
and the "O&M zone" is formally referred to as the Management and Analytics Layer.
2.Which of the following vendors offers the Wi-Fi Shield feature?
A. Aruba
B. Extreme Networks
C. Cisco
D. Huawei
Answer: D
Explanation:
Wi-Fi Shield is a signature security technology exclusive to Huawei AirEngine series APs (specifically
Wi-Fi 6 Advanced and Wi-Fi 7 models). It leverages advanced beamforming and the addition of
interference signals to create a "secure zone" around an authorized user. By sending precise interference
to non-target directions, it ensures that even if a malicious user intercepts the signal, they receive only
disordered noise that cannot be demodulated. This is a key differentiator in Huawei’s Xinghe Intelligent
Campus security framework.
3.What benefits does Huawei's IT and OT converged production network solution deliver to customers?
A. Intelligent wireless connections
B. Intelligent O&M
C. Flexible manufacturing
D. Digital and intelligent production
Answer: A, D
Explanation:
Huawei’s Campus Production Network Solution (specifically for Industrial/Manufacturing scenarios)
focuses on the convergence of Information Technology (IT) and Operational Technology (OT).
The primary benefits highlighted in the HCSP V2.0 guides are:
Intelligent wireless connections (A): Using Wi-Fi 6/7 with deterministic latency to replace cables on the
factory floor, enabling mobile production.
Digital and intelligent production (D): The ultimate goal of the convergence is to enable real-time data
collection from sensors (OT) to the cloud (IT), facilitating the transformation to Smart Manufacturing.
Note: While Intelligent O&M is a feature of the platform, A and D are the specific strategic benefits defining
the "IT/OT Convergence" value proposition.

4.MIMO technology enables multiple antennas to send and receive spatial streams (multiple signals)
simultaneously and to differentiate the signals sent to or received from different spatial orientations.
By leveraging technologies such as SM and SD, MIMO boosts the system capacity, coverage scope, and
SNR without occupying extra bandwidth.
A. True
B. False
Answer: A
Explanation:
MIMO (Multiple-Input Multiple-Output) is a core pillar of modern WLAN planning.
It utilizes two main techniques:
Spatial Multiplexing (SM): Increases system capacity by transmitting different data treams over different
antennas simultaneously.
Spatial Diversity (SD): Improves coverage scope and SNR (Signal-to-Noise Ratio) by transmitting the
same data stream over multiple paths to ensure reliability through re undancy (e.g., using MRC or STBC).
The statement is True because these benefits are achieved using the same frequency channel (no extra
bandwidth) by exploiting the spatial dimension of the radio environment.
5.An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
A. True
B. False
Answer: B
Explanation:
In Huawei’s WLAN solution, APs can operate in different modes. While Fit APs require a Wireless Access
Controller (WAC) and Cloud APs are managed by iMaster NCE-Campus, Huawei also supports Fat APs.
A Fat AP (standalone mode) can perform authentication, encryption, and data forwarding independently
without a centralized controller. Therefore, the statement that an AP cannot work independently is false. In
the Xinghe Intelligent Campus solution, most deployments use Cloud or Fit modes for centralized
management, but the hardware capability for standalone operation remains.
6.Which of the following encryption modes is used in WAPI authentication?
A. Web
B. SM4
C. TKIP
D. CCMP
Answer: B
Explanation:
WAPI (WLAN Authentication and Privacy Infrastructure) is a Chinese national standard for wireless
security. Unlike the international WPA standards that use AES (CCMP) or the legacy TKIP, WAPI utilizes
the SM4 (formerly SMS4) symmetric block cipher algorithm for data encryption and the SM3 hash
algorithm for integrity. Huawei enterprise APs support WAPI to meet specific regulatory and security
requirements in the Chinese market.
7.Which of the following technologies is used to improve air interface security?

4 / 5
A. WDS
B. DTLS
C. IPsec
D. PMF
Answer: D
Explanation:
PMF (Protected Management Frames), defined in the 802.11w standard, is the primary technology used
to enhance security specifically over the air interface. While WDS is for bridging, and DTLS/IPsec are
used for tunnel encryption (like CAPWAP), PMF protects management frames (such as Disassociation,
Deauthentication, and Robust Action frames) from being forged or spoofed by attackers. This prevents
common DoS (Denial of Service) attacks where an attacker forcibly disconnects legitimate users from the
Wi-Fi network.
8.Which of the following packet priority queues are supported over the air interface?
A. VO queue
B. BK queue
C. BE queue
D. VI queue
Answer: A, B, C, D
Explanation:
Huawei’s air interface scheduling follows the WMM (Wi-Fi Multimedia) standard, which maps data
packets into four Access Categories (ACs) to ensure Quality of Service (QoS).
These queues are:
VO (Voice): Highest priority for low-latency voice traffic.
VI (Video): High priority for video streaming.
BE (Best Effort): Standard priority for general data traffic.
BK (Background): Lowest priority for non-time-critical tasks like file downloads or print jobs.
9.What types of attack detection are supported over the air interface?
A. Flood attack detection
B. Spoofing attack detection
C. Weak IV attack detection
D. Brute force PSK cracking detection
Answer: A, B, C, D
Explanation:
Huawei’s WIDS (Wireless Intrusion Detection System) and WIPS (Wireless Intrusion Prevention System)
provide comprehensive air interface protection.
They are designed to detect:
Flood attacks (A): Detecting an abnormal volume of management frames (like Auth/Deauth floods).
Spoofing attacks (B): Detecting unauthorized APs or STAs using the MAC addresses of authorized
devices.
Weak IV attacks (C): Detecting attempts to exploit older encryption (like WEP) by identifying weak
Initialization Vectors.
Brute force cracking (D): Monitoring for repeated authentication failures that indicate an attempt to guess

WPA/WPA2-PSK or WAPI-PSK keys.
10.NETCONF is based on the Extensible Markup Language (XML).
A. True
B. False
Answer: A
Explanation:
NETCONF (Network Configuration Protocol) is the primary management protocol used in the Xinghe
Intelligent Campus solution for communication between iMaster NCE-Campus and network devices. It
uses a multi-layer structure where the Content Layer (data) and Operations Layer are encoded in XML.
This allows for a structured, hierarchical representation of configuration data and state information,
making it more efficient and programmable than traditional CLI or SNMP.11.Which of the following APs is not involved in the campus energy saving solution?
A. Energy-saving AP
B. IoT AP
C. Leader AP
D. Assurance AP
Answer: B
Explanation:
Huawei’s Intelligent Energy Saving Solution (Zero-bit, Zero-watt) uses AI to transition APs between states
based on traffic demand. In this logic:
Energy-saving APs (A): Are those identified by the system to enter a deep sleep/hibernation mode when
traffic is low.
Assurance APs (D): Remain active to provide basic signal coverage and "listen" for wake-up triggers.
Leader APs (C): Function as the local controller (in small-scale deployments) to coordinate these states.
IoT APs (B), while they support converged services, are not defined as a specific functional role within the
energy-saving state-switching algorithm itself, as IoT devices often require persistent, low-power
connectivity that differs from standard Wi-Fi user traffic patterns.
12.Which of the following information is contained in the DHCP snooping binding table?
A. VLAN
B. MAC address
C. Interface
D. IP address
Answer: A, B, C, D
Explanation:
DHCP Snooping is a key security feature in campus access layer design. When a client obtains an IP
address, the switch populates a binding table that links the MAC address (B) and the assigned IP address
(D) to the specific physical Interface (C) and the VLAN (A) ID. This table is then used by other security
features like Dynamic ARP Inspection (DAI) and IP Source Guard (IPSG) to prevent spoofing attacks by
verifying that incoming traffic matches the authorized entries in the binding table.
