NEW QUESTION # 18
Free mobility is deployed on a campus network through iMaster NCE-Campus. During this deployment, which of the following steps are performed by administrators and which are automatically performed by iMaster NCE-Campus?
Answer:
Explanation:
Explanation:
Administrator:
- Defining a Security Group
- Defining a Policy Control Matrix
iMaster NCE-Campus:
- Delivering IP-Group Entries
- Delivering a Policy Control Matrix
In Huawei's free mobility solution, responsibilities are clearly divided betweenadministratorsandiMaster NCE- Campusto achieve centralized control with automated policy delivery. Administrators are responsible forpolicy and security intent definition, while iMaster NCE-Campus handlesautomatic distribution and enforcement coordination.
Administrators firstdefine security groups, which represent logical user or terminal categories such as employees, guests, or IoT devices. These security groups form the basis of identity-based access control in the campus network. Administrators alsodefine the policy control matrix, which specifies communication permissions between different security groups, such as allow, deny, or redirect. This step represents business intent and security requirements and must be manually planned and configured.
Once these definitions are complete,iMaster NCE-Campus takes over the execution phase. It automaticallydelivers the policy control matrixto authentication points and policy enforcement points, translating high-level policies into device-level configurations. This ensures consistent policy enforcement across the entire campus network.
In addition, iMaster NCE-Campus automaticallydelivers IP-group entries, which bind user IP addresses to security groups. These entries are dynamically generated based on authentication results and are distributed to relevant devices so that traffic can be correctly identified and controlled as users move.
This division of labor aligns with HCIP Datacom Campus Network design principles, enabling simplified administration, reduced manual configuration, and truly seamless free mobility across the campus network.

(The egress zone is the boundary between a campus network and external networks, including the Internet and WAN. It bridges the intranet and extranet and protects the security of the campus network. Which of the following are requirements for egress zone design?)
- A. Network secure ensurance
- B. Network connectivity
- C. Various and flexible access modes
- D. Service control capability
Answer: A,B,C,D
Explanation:
In campus network architecture, theegress zoneplays a critical role as the boundary between the internal campus network and external networks such as the Internet, WAN, or cloud services. According to HCIP Datacom Campus Network design principles, the egress zone must meet multiple functional and security requirements to ensure stable, secure, and flexible network operation.
First,network connectivityis a fundamental requirement. The egress zone must reliably connect the campus intranet to external networks, ensuring uninterrupted access to external resources and services. High availability and redundancy are often considered in this aspect to avoid single points of failure.
Second,network secure ensuranceis essential. As the main security boundary, the egress zone must protect the campus network from external threats. This typically involves deploying security mechanisms such as firewalls, intrusion prevention, traffic filtering, and attack defense to ensure data and service security.
Third, the egress zone must provide strongservice control capability. This includes traffic identification, policy-based forwarding, bandwidth management, and application control. These capabilities allow administrators to optimize service quality, prioritize critical applications, and manage user access to external services.
Finally,various and flexible access modesare required to support different external connection scenarios, such as Internet access, MPLS WAN access, VPN connections, and cloud interconnection. This flexibility enables the campus network to adapt to evolving business and service requirements.
Therefore, all listed options are essential requirements for proper egress zone design, makingA, B, C, and Dthe correct answers.

NEW QUESTION # 23
(When you configure a virtualized campus network on iMaster NCE-Campus, Fit APs can immediately go online after you add them to iMaster NCE-Campus.)
- A. TRUE
- B. FALSE
Answer: B
Explanation:
In a Huawei virtualized campus network managed byiMaster NCE-Campus,Fit APs do not go online immediatelyafter being added to the management platform. According to HCIP Datacom Campus Network documentation, Fit APs depend on awireless access controller (AC)for control, configuration delivery, and service provisioning. Simply adding a Fit AP to iMaster NCE-Campus only completes thedevice registration step, not the full service enablement process.
After a Fit AP is added, several additional steps are required before it can go online and provide wireless services. First, the AP must successfullydiscover and establish a control tunnel with the AC. Then, the AP typically needs to beapproved, assigned to a site, and bound to the correctAP group. Configuration data such as radio parameters, SSIDs, security policies, and authentication profiles must also be delivered from the AC to the AP.
In addition, firmware version checks or upgrades may occur during the onboarding process to ensure compatibility with the controller and management platform. Only after these steps are completed can the Fit AP enter thenormal online stateand start providing WLAN services.
This multi-step process ensures centralized control, consistent configuration, and reliable operation across large-scale campus networks, but it also means Fit APs cannot immediately go online upon being added to iMaster NCE-Campus.
Therefore, the statement is incorrect, and the correct answer isFALSE.

- D. Relying solely on TCP retransmission mechanisms to recover lost packet data.
Answer: C
NEW QUESTION # 27
(To isolate communication between wired terminals, you can enable port isolation on the access switches.
However, APs cannot implement wireless user isolation.)
- A. TRUE
- B. FALSE
Answer: B
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
Port isolation is commonly used on access switches to preventwired terminalsfrom communicating directly with each other at Layer 2. This enhances security by blocking lateral attacks and unnecessary broadcast traffic.
Forwireless users, Huawei APs and WLAN controllers (or central APs in agile distributed scenarios) provide wireless user isolationmechanisms. Wireless user isolation prevents clients connected to the same SSID or AP from directly communicating with each other, even though they share the same wireless medium. This is widely used in guest networks, dormitories, and public WLAN environments.
Therefore, the statement that APs cannot implement wireless user isolation is incorrect. According to HCIP Datacom Campus Network WLAN design principles,wireless user isolation is fully supported by APs, either locally or under centralized control.
Hence, the statement is FALSE, and option B is correct.
NEW QUESTION # 28

- D. Designated Router (DR) within the area
Answer: A
NEW QUESTION # 30
(During WLAN planning and design, channels 1, 6, and 11 are recommended on the 2.4 GHz frequency band, and channels 1, 5, 9, and 13 are recommended in high-density scenarios. On the 5 GHz frequency band, it is recommended that high-frequency and low-frequency channels of adjacent APs be staggered to prevent overlapping.)
- A. FALSE
- B. TRUE
Answer: B
Explanation:
WLAN planning and design aim to minimize co-channel and adjacent-channel interference while maximizing spectrum utilization and user experience. According to HCIP Datacom Campus Network WLAN design principles, proper channel planning is a core task, especially in environments with high user density.
On the2.4 GHz frequency band, only three non-overlapping channels-1, 6, and 11-are traditionally recommended. These channels do not overlap in frequency, which helps reduce interference between adjacent APs. Inhigh-density scenarios, to further improve spectrum utilization,channels 1, 5, 9, and 13can be used.
This approach shortens the channel spacing but is acceptable when transmit power is well controlled and AP placement is carefully planned, enabling higher AP density while keeping interference manageable.
On the5 GHz frequency band, there are more available channels and less interference compared to 2.4 GHz.
HCIP Datacom documentation recommendsstaggering high-frequency and low-frequency channels between adjacent APs. This staggered channel allocation reduces the likelihood of co-channel interference and improves overall throughput and roaming performance, especially in large or high-density campus deployments.
These channel planning strategies are standard WLAN design best practices supported by Huawei and are widely applied in enterprise campus networks. Therefore, the statement accurately reflects recommended WLAN planning principles and isTRUE.

- C. Service Traffic Bandwidth Statistics
- D. VPN Tunnel Status Monitoring and Alerts
Answer: D
NEW QUESTION # 33
(Which of the following statements about VXLAN isfalse?)
- A. A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and for communication with a non-VXLAN external network.
- B. A Layer 2 VXLAN gateway forwards traffic to a VXLAN network or implements intra-subnet communication on the same VXLAN network.
- C. Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
- D. A VBDIF interface is a logical interface created based on a BD and is similar to a VLANIF interface on a traditional network.
Answer: C
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
In a VXLAN-based campus network,VBDIF interfacesserve as Layer 3 gateway interfaces for Bridge Domains (BDs) and provide routing capabilities. However, not all VXLAN gateways must maintain VBDIF interfaces. This makes statementA false.
ALayer 2 VXLAN gatewayoperates purely at Layer 2 and is responsible for VXLAN encapsulation and decapsulation, enabling intra-subnet communication within the same VXLAN network. It doesnot require a VBDIF interface, because no Layer 3 routing is involved. Therefore, claiming that both Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces is incorrect.
Statement B is correct because a VBDIF interface is a logical Layer 3 interface bound to a BD and functions similarly to a VLANIF interface in traditional VLAN-based networks. Statement C is also correct, as aLayer
3 VXLAN gatewayenables inter-subnet routing between different VNIs and allows traffic to exit the VXLAN network toward non-VXLAN external networks. Statement D correctly describes the function of a Layer 2 VXLAN gateway.
According to HCIP Datacom Campus Network documentation, VBDIF interfaces are mandatory only for Layer 3 VXLAN gateways, not for Layer 2 VXLAN gateways.
NEW QUESTION # 34
