NEW QUESTION # 22
The AirEngine 8771-X1T has dynamic-zoom smart antennas that can switch between omnidirectional and high-density modes.

• A. False
• B. True

Answer: B

Explanation:
The statement is true. The AirEngine 8771-X1T uses dynamic-zoom smart-antenna technology that can adapt its radiation characteristics according to the deployment environment. In omnidirectional mode, the antenna pattern is optimized to provide broad and balanced coverage, making it appropriate for ordinary offices, corridors, classrooms, and other environments where users are distributed over a relatively large area.
In high-density mode, the antenna pattern is adjusted to concentrate radio energy more effectively within the intended service area. This reduces unnecessary signal leakage, limits interference between neighboring APs, and improves concurrent-user performance in lecture halls, conference rooms, auditoriums, and similar high- density environments.
The switching capability is more effective than using a permanently fixed antenna pattern because WLAN conditions can change as users move and traffic density increases or decreases. Huawei's training material states that dynamic-zoom smart antennas dynamically switch between omnidirectional and high-density modes, improving coverage in omnidirectional mode while strengthening the user experience in high-density scenarios. Therefore, option A is correct.

NEW QUESTION # 23
In the energy-saving solution based on AI traffic prediction, IoT APs are recommended to operate in non- energy-saving mode by default.

• A. False
• B. True

Answer: B

Explanation:
The statement is true. AI-based energy-saving systems analyze historical traffic and usage patterns to predict periods of low network demand. Ordinary AP radios or access devices can then enter an energy-saving state when their capacity is not required, while surrounding devices maintain sufficient coverage and service availability.
IoT APs, however, may host continuously operating IoT cards, sensors, electronic shelf-label services, Bluetooth location functions, RFID services, healthcare devices, or asset-tracking terminals. Placing such an AP into an energy-saving or hibernation state could interrupt more than ordinary Wi-Fi connectivity. It could also disable an IoT module's power supply, management channel, data backhaul, or persistent sensing function. Huawei's Wi-Fi and IoT convergence architecture uses APs as shared locations, power sources, and communication channels for IoT services.
Huawei also applies intelligent technologies to analyze AP load trends and perform predictive network optimization. The safer default is therefore to exclude IoT APs from automatic energy-saving actions unless the administrator confirms that their attached IoT services tolerate interruption. Accordingly, the answer is True.

NEW QUESTION # 24
In the High-Quality 10 Gbps Campus Network Solution, which of the following experiences is improved by iMaster NCE-Campus?

• A. Wireless experience
• B. Application experience
• C. Wired experience
• D. O & M experience

Answer: D

Explanation:
iMaster NCE-Campus primarily improves the operations and maintenance experience in this solution. It provides centralized planning, deployment, configuration, policy orchestration, monitoring, topology management, device management, alarm handling, and maintenance through a unified graphical interface.
Instead of configuring each switch, AP, WAC, firewall, or router separately, administrators can define services and policies centrally and deliver them across the network. Huawei states that iMaster NCE-Campus provides integrated LAN and WAN management, integrated deployment, integrated policies, and integrated O
& M, thereby improving deployment and O & M efficiency. It also provides network monitoring, service alarms, file management, log management, device maintenance, user management, and virtual-network management from one platform.
Wireless, wired, and application experience analysis is more directly associated with iMaster NCE- CampusInsight, which uses telemetry, AI, protocol tracing, and predictive analysis to quantify user and application experience. iMaster NCE-Campus serves as the management and control platform that simplifies administrators' daily work. Therefore, the experience specifically improved by iMaster NCE-Campus is the O
& M experience, making option C correct.

NEW QUESTION # 25
Which of the following can be determined through a survey of the terminal types on a customer's network?

• A. Network access solution
• B. Network admission control solution
• C. Network O & M solution
• D. Network architecture

Answer: B

Explanation:
A terminal-type survey primarily determines the appropriate network admission control solution. Different terminal categories have different authentication capabilities and security requirements. Corporate laptops may support 802.1X authentication, guests may require Portal authentication, and printers, cameras, sensors, and other dumb terminals commonly require MAC-address authentication or automatic terminal identification.
Huawei recommends selecting authentication technologies according to the terminal type and usage scenario.
For example, access switches can serve as authentication points for wired dumb terminals, while APs or other access devices can perform authentication for wireless users. After terminal identification is enabled, iMaster NCE-Campus can automatically assign VLANs, ACLs, security groups, QoS parameters, and other authorization policies according to terminal category.
The survey therefore establishes which endpoints support interactive authentication, which require non- interactive admission, and which must receive special isolation or compliance policies. It does not independently determine the complete physical network architecture or the overall O & M platform.
Consequently, the terminal survey is used to formulate the network admission control solution, making option C correct.

NEW QUESTION # 26
Which of the following is not part of an IFIT measurement model?

• A. Measurement flow
• B. Measurement direction
• C. Measurement point
• D. NMS

Answer: D

Explanation:
The Network Management System is not an element of the IFIT measurement model. An IFIT measurement definition identifies the traffic to be measured, the locations where measurement actions occur, and the direction in which the flow is evaluated. The measurement flow specifies the target packets, usually through flow-identification fields. Measurement points define where packets are marked, counted, timestamped, or reported, such as ingress, transit, and egress nodes. Measurement direction distinguishes forward and reverse monitoring so that packet loss, delay, and path behavior can be analyzed correctly for each direction.
An NMS or controller remains operationally important because it creates measurement tasks, distributes configurations, receives telemetry data, correlates the results, and presents fault-location information.
However, it is the management and analysis system surrounding the measurement model, not one of the model's constituent measurement parameters.
Huawei positions IFIT as a high-precision telemetry mechanism used to delimit and locate application-quality faults. The training material highlights IFIT's capability to locate faults rapidly and detect packet loss with extremely high reliability. Therefore, the component that is not part of the measurement model is the NMS.

NEW QUESTION # 27
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: D

Explanation:
A central switch in the relevant passive Ethernet network architecture supports a maximum of 48 access units.
The architecture replaces a conventional multi-layer access design with a centralized switch and distributed remote or access units. The access units function as extensions of the central switch's ports, simplifying device management, configuration, and topology maintenance.
Huawei's CloudEngine S5731-H fixed central-switch specification provides models with 24 or 48 hybrid optical-electrical downlink ports. The 48-port model can therefore directly manage up to 48 associated access or remote units under the design limits represented by this question. The same hybrid links can provide data transmission and remote PoE power, enabling access units to be installed closer to terminals without requiring conventional active aggregation equipment at every location.
The central switch automatically discovers the topology, while remote units behave as extended ports rather than independently managed switches. This reduces management nodes and simplifies a traditional three- layer network into a two-layer architecture. The larger values of 64, 72, and 96 exceed the supported maximum for the specified central-switch implementation. Therefore, option C is correct.

NEW QUESTION # 28
Which of the following statements is false about GRE over IPsec?

• A. Compared with tunnel mode, transport mode adds an additional outer IP header. As a result, the packet is longer and more likely to be fragmented. Therefore, GRE over IPsec in tunnel mode is recommended.
• B. IPsec supports encapsulation in both tunnel and transport modes.
• C. GRE over IPsec first encapsulates packets using GRE and then protects the GRE packets using IPsec.
• D. IPsec protects data flows between the GRE tunnel source and GRE tunnel destination.

Answer: A

Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.

NEW QUESTION # 29
Which of the following Wi-Fi 7 APs offers PCIe card-based IoT functions?

• A. AirEngine 8771-X1T
• B. AirEngine 6776I-X6TH
• C. AirEngine 6776-58TI
• D. AirEngine 5773-25HW

Answer: B

Explanation:
The AirEngine 6776I-X6TH is the model designed to provide PCIe card-based IoT expansion. The PCIe interface enables an appropriate IoT expansion card to be installed so that the AP can support additional wireless or sensing technologies according to the deployment requirement. This allows the same physical access infrastructure to deliver enterprise Wi-Fi and IoT connectivity.
The capability is useful in retail, healthcare, education, manufacturing, and asset-management environments, where technologies such as Bluetooth, RFID, Zigbee, electronic shelf labels, location services, or specialized sensing systems may need to coexist with the WLAN. A modular card design is preferable when an organization requires selectable or upgradeable IoT functions rather than only fixed integrated capabilities.
Huawei's Wi-Fi and IoT convergence architecture reduces repeated cabling, separate power systems, and independently managed wireless networks. It enables an IoT-capable AP to provide the installation position, power, management connectivity, and uplink data channel required by IoT modules. Among the models listed, the AirEngine 6776I-X6TH is the PCIe card-based IoT model. Therefore, option A is correct.

NEW QUESTION # 30
Intelligent policy recommendation can achieve network-level load balancing.

• A. False
• B. True

Answer: B

Explanation:
The statement is true. Intelligent policy recommendation does not consider only the traffic load of an individual interface or device. iMaster NCE-Campus obtains network topology, application, link-quality, bandwidth-utilization, and traffic-distribution information from multiple devices. It can then recommend or orchestrate policies that distribute traffic across the network's available paths and resources.
For example, when multiple WAN links have the same priority and satisfy an application's SLA requirements, per-flow load balancing can distribute different application flows among those links.
Bandwidth-proportional balancing can also account for differences in link capacity, preventing a lower- bandwidth link from being overloaded. Huawei explains that load-balancing-based traffic steering can fully utilize multiple links and distribute flows across links meeting the required SLA.
Because iMaster NCE-Campus centrally manages CPEs and uniformly orchestrates service intent across the overlay network, recommendations can be evaluated from a network-wide perspective instead of through isolated local decisions. Therefore, intelligent policy recommendation can implement network-level load balancing.

NEW QUESTION # 31
The CNN-based application identification technology can identify both known and unknown applications.

• A. False
• B. True

Answer: B

Explanation:
The statement is true in the context of Huawei's AI-assisted application-identification architecture.
Conventional identification depends mainly on predefined signatures, fixed destination addresses, port numbers, protocol fields, DNS correlation, or deep packet inspection. Huawei's standard SD-WAN process uses Service Awareness and First-Packet Identification signature databases to identify and group application traffic. These mechanisms are effective for known applications but become less reliable when traffic is encrypted, applications change versions, or previously unseen applications appear.
A CNN-based classifier learns multidimensional traffic characteristics such as packet-length sequences, timing, direction, and flow behavior. It can classify traffic matching learned application patterns and, when implemented with open-set detection, recognize flows outside known classes as unknown or zero-day applications. Commercial-grade deep-learning traffic classification research demonstrates identification of known encrypted applications together with the handling of unknown zero-day applications.
This does not mean the system automatically assigns an exact commercial name to every unseen application.
It detects that the traffic does not match established classes so that it can be investigated, labelled, and incorporated into later model updates. Therefore, the statement is True.

NEW QUESTION # 32
Which of the following are common terminal identification methods?

• A. SNMP query
• B. MAC OUI
• C. DHCP option
• D. Nmap

Answer: A,B,C,D

Explanation:
All four options are recognized terminal identification methods. MAC OUI examines the first three bytes of a device's MAC address to determine its manufacturer, although it generally cannot identify the exact model or operating system. DHCP option identification analyzes fields such as DHCP options 12, 55, and 60, which can reveal the hostname, parameter-request list, vendor class, and other terminal characteristics. SNMP query is an active identification method that retrieves device details from relevant MIB objects and is particularly useful for printers, network devices, and other SNMP-capable equipment.
Nmap is also an active scanning method. It analyzes open ports, service responses, protocol behavior, and operating-system fingerprints to estimate a terminal's device type and OS. Huawei distinguishes information- reporting methods from proactive scanning methods: MAC OUI and DHCP options generally use information observed in traffic, whereas SNMP and Nmap actively query or scan the endpoint. iMaster NCE-Campus can correlate multiple fingerprints to improve identification accuracy and automatically apply terminal-specific access policies.

NEW QUESTION # 33
On a campus fabric network, which of the following methods can be used for non-authenticated terminals to access a VN?

• A. Authorizing VLANs in wired mode
• B. Configuring static VLANs
• C. Dynamically authorizing VLANs
• D. Authorizing VLANs in wireless mode

Answer: B

Explanation:
Non-authenticated terminals can access a virtual network by using statically configured VLANs. Such terminals may include printers, cameras, sensors, industrial devices, and other dumb terminals that cannot perform 802.1X, Portal, or comparable interactive authentication. Their access interfaces and service VLANs are therefore configured in advance and mapped to the required VN.
Dynamic VLAN authorization requires a completed authentication or identification process. Normally, an authentication server returns a VLAN or other authorization attribute after validating the user or terminal.
Because the question specifically refers to non-authenticated terminals, dynamically authorizing a VLAN is not the applicable mechanism. The wired-mode and wireless-mode authorization options are likewise associated with authentication-based policy delivery rather than unconditional VN access.
Huawei's VN design guidance states that LAN-side physical interfaces and VLANs are assigned to the appropriate departments or services and then associated with corresponding VRFs or VNs. It also explains that a department may use an independent physical interface or share an interface while maintaining isolation through VLANs. Therefore, configuring a static VLAN is the correct method.

NEW QUESTION # 34
Which of the following technologies is used for wireless attack detection?

• A. WIPS
• B. Spectrum analysis
• C. PMF
• D. Mesh

Answer: A

Explanation:
WIPS is the correct technology because it provides wireless intrusion prevention capabilities, including detecting and containing rogue access points, rogue stations, ad hoc devices, spoofing attempts, flood attacks, and other malicious activity on the radio interface. Huawei's security-design material groups WIDS and WIPS with wireless attack detection and rogue-device containment. It recommends attack detection in public areas and primary or secondary education environments with high security requirements.
WIDS primarily detects and reports suspicious behavior, while WIPS adds active prevention or containment actions according to the configured policy. The other options serve different purposes. Mesh is a wireless networking architecture used to provide backhaul connectivity or extend coverage between APs; it is not an attack-detection mechanism. Spectrum analysis identifies non-Wi-Fi interference sources and evaluates radio- frequency utilization, but does not provide complete security attack detection and containment. Protected Management Frames protects selected 802.11 management frames against forgery, deauthentication, and disassociation attacks, but it is a protection mechanism rather than the comprehensive detection system requested. Therefore, WIPS is the correct answer.

NEW QUESTION # 35
Which of the following statements is false?

• A. Traditional QoS technologies can provide differentiated services to meet the requirements of voice, video, and data services.
• B. Hierarchical Quality of Service (HQoS) uses queue-based hierarchical scheduling to provide fine- grained quality assurance for services of different users.
• C. Traditional QoS can manage or schedule traffic of multiple services for multiple users simultaneously.
• D. Traditional QoS schedules traffic based on interface bandwidth, allowing services to be differentiated by service level. However, it is difficult to differentiate services by user. Therefore, traditional QoS is typically applied at the core layer rather than the access layer.

Answer: C

Explanation:
Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.
Huawei's material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.
HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.

NEW QUESTION # 36
Which of the following SM-series cryptographic algorithms is supported?

• A. SM1
• B. SM2
• C. SM4
• D. SM5

Answer: C

Explanation:
SM4 is the supported SM-series cryptographic algorithm intended by this question. SM4 is a standardized symmetric block cipher that uses a 128-bit block size and a 128-bit key. It is suitable for high-volume data encryption because symmetric cryptography can process service traffic efficiently compared with public-key algorithms.
Within an SD-WAN or IPsec context, the bulk traffic carried through secure data channels requires a symmetric encryption algorithm. SM4 can therefore be used as the encryption component of an approved cryptographic suite where compliance with Chinese commercial cryptography requirements is necessary.
SM2 is an asymmetric public-key cryptographic suite used for functions such as digital signatures, key exchange, and public-key encryption. It is not the bulk data-encryption algorithm requested in this item. SM1 is a restricted proprietary algorithm whose implementation details are not publicly standardized in the same manner, while SM5 is not the supported option represented by the Huawei course question.
Huawei's SD-WAN architecture uses IPsec to protect site-to-site services and supports secure GRE-over- IPsec data channels between edge devices. In the SM-series selection presented here, the correct supported traffic-encryption algorithm is SM4.
