A typical campus network consists of the terminal layer, access layer, aggregation layer, core layer, egress zone, and O&M zone.
Answer(s): B
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.
Which of the following vendors offers the Wi-Fi Shield feature?
Answer(s): D
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.
What benefits does Huawei's IT and OT converged production network solution deliver to customers?
Answer(s): A,D
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.
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.
Answer(s): A
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 streams 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 redundancy (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.
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
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.
Which of the following encryption modes is used in WAPI authentication?
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.
Which of the following technologies is used to improve air interface security?
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, andDTLS/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.
Which of the following packet priority queues are supported over the air interface?
Answer(s): A,B,C,D
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.

excellent topics covered
are these really financial cloud questions and answers, seems these are basic admin question and answers
are these comments real
please upload the latest dumps
a company runs its workloads on premises. the company wants to forecast the cost of running a large application on aws. which aws service or tool can the company use to obtain this information? pricing calculator ... the aws pricing calculator is primarily used for estimating future costs
looks interesting
thanks! that’s amazing
the exam dumps are helping me get a solid foundation on the practical techniques and practices needed to be successful in the auditing world.
q 14 should be dmz sever1 and notepad.exe why does note pad have a 443 connection
question # 108, correct answers are business growth and risk reduction.
are these valid chfi questions
question: 162 should be dlp (b)
good exam questions
I have to say this is really close to real exam. Passed my exam with this.
good analytics question
this looks accurate
question 46, the answer should be data "virtualization" (not visualization).
its useful.
Pass this exam 3 days ago. The PDF version and the Xengine App is quite useful.
informative for me.
question 134s answer shoule be "dlp"
in 72 the answer must be [sys_user_has_role] table.
i appreciated the mix of multiple-choice and short answer questions. i passed my exam this morning.
great to find this website, thanks
examination questions seem to be relevant.
planning to take psm test
please allow to download
please provide dumps
is the answer to question 15 correct ? i feel like the answer should be b
its getting more technical
i think these questions are what i need.
