NEW QUESTION # 49
iMaster NCE-Campus can identify terminals. Which of the following services can be provided after terminal identification?
Answer: A,B,D
Explanation:
After identifying a terminal, iMaster NCE-Campus can use the identification result for security monitoring, visibility, and policy automation. Spoofing detection is supported because the platform can compare a terminal's current type and traffic behavior with its previously identified characteristics. For example, if a device originally identified as an IP phone suddenly behaves like a PC, the system can generate a spoofing alarm or apply an isolation policy.
Terminal identification also supports statistics and reporting by vendor, operating system, device category, access port, and policy status. Huawei explicitly describes terminal-type statistics, report export, and visibility of access policies.
In addition, iMaster NCE-Campus can automatically deliver VLAN, security-group, QoS, authentication, and access-permission policies according to the identified terminal type. Option B is incorrect because wired authentication is an admission process, not a service produced after terminal identification. Therefore, A, C, and D are correct.
NEW QUESTION # 50
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?
Answer: A
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 # 51
Which of the following wireless security standards was proposed by China?
Answer: B
Explanation:
WAPI, or WLAN Authentication and Privacy Infrastructure, is the wireless LAN security standard proposed by China. It provides wireless link authentication and data-protection mechanisms and was developed as an alternative security framework for WLAN environments. Huawei's training material explicitly identifies WAPI as a WLAN security standard proposed in China and states that it provides stronger protection than legacy WEP and WPA mechanisms.
WPA, WPA2, and WPA3 belong to the Wi-Fi Protected Access family maintained through Wi-Fi industry certification. WPA was introduced as an interim improvement over WEP. WPA2 adopted stronger IEEE
802.11i security mechanisms, including AES-based CCMP. WPA3 later introduced stronger password- authentication and enterprise-security options.
WAPI incorporates authentication and encryption as part of an integrated wireless security architecture. Its deployment depends on regional requirements, terminal compatibility, AP support, and the organization's regulatory or cryptographic-policy obligations. The question asks which standard originated as a Chinese wireless security standard, not which standard is most widely deployed internationally. Therefore, WAPI is the only correct choice, making option B the verified answer.
NEW QUESTION # 52
On a campus fabric network, which of the following methods can be used for non-authenticated terminals to access a VN?
Answer: A
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 # 53
Which of the following statements are true about wireless traffic forwarding modes on a fabric wireless network?
Answer: A,B,C,D
Explanation:
All four statements correctly describe the trade-offs between direct and tunnel forwarding. With direct forwarding, an AP sends service traffic directly to the upstream network rather than encapsulating it in a CAPWAP data tunnel to the WAC. This eliminates unnecessary detours, avoids creating a WAC bandwidth bottleneck, reduces WAC load, and generally provides higher forwarding efficiency.
However, on a fabric network, Layer 3 roaming across different edge nodes may require the original edge or another designated device to remain the home agent. The resulting forwarding path and state synchronization can slightly affect roaming performance, making direct forwarding less suitable for extremely roaming- sensitive deployments. Huawei's material explains that after Layer 3 roaming in direct-forwarding mode, traffic may continue to be forwarded through the home agent.
Tunnel forwarding sends AP service traffic through CAPWAP tunnels to the WAC. This simplifies centralized policy enforcement, security control, and traffic management. Its disadvantage is that all wireless traffic may detour through the WAC, increasing forwarding pressure and potentially creating a performance bottleneck.
