37. Frage
iMaster NCE-Campus can be installed in an environment where a third-party server, VMware, and SUSE are deployed.
Antwort: A
Begründung:
The statement is true. iMaster NCE-Campus supports multiple on-premises deployment combinations rather than being restricted exclusively to Huawei-branded physical servers and Huawei virtualization platforms.
The training material explicitly lists physical-server deployment using SUSE Linux and a third-party server, as well as virtual-machine deployment using VMware.
The platform can also be deployed using Huawei server and virtualization combinations, including Huawei
2288X servers, EulerOS, FusionCompute, and TaiShan-based environments. The availability of several combinations enables customers to select an architecture consistent with their existing data-center standards, procurement strategy, virtualization environment, and operational requirements.
Huawei nevertheless identifies a recommended platform combination in the training material. A recommendation does not mean that the other listed combinations are unsupported; it identifies the preferred configuration for standardized deployment and support. The material displays third-party server plus SUSE Linux and VMware-based virtual-machine deployment as valid alternatives while recommending Huawei
2288X V5 plus EulerOS.
The deployment must still satisfy the specified CPU, memory, storage, network-interface, software-version, and compatibility requirements. Therefore, the statement is True.
38. Frage
How many ports can a 400GE card offer on the CloudEngine S16700 series next-generation flagship core switches?
Antwort: A
Begründung:
A high-density 400GE service card for the CloudEngine S16700 series can provide 18 ports. The S16700 is positioned as a next-generation flagship campus core switch designed for ultra-high-capacity aggregation, large-scale Wi-Fi backhaul, data-center interconnection, and long-term bandwidth evolution.
An 18-port 400GE card provides a theoretical aggregate port rate of 7.2 Tbit/s in each direction before considering the switching fabric's internal architecture and forwarding design. This density allows a single chassis slot to aggregate numerous high-speed distribution switches, connect multiple campus fabrics, or provide high-bandwidth links toward data centers and service platforms. It also reduces the number of cards and chassis required compared with lower-density 8-port, 12-port, or 16-port alternatives.
The question asks specifically for the number of physical 400GE interfaces offered by the card, not the entire chassis capacity or the number of ports after breakout. Under the H19-404 product-portfolio specification represented by this question, the correct density is 18 native 400GE ports. Therefore, option B is correct.
39. Frage
Which of the following wireless security standards was proposed by China?
Antwort: A
Begründung:
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.
40. Frage
Which of the following deployment modes are supported by AR routers?
Antwort: B,C,D
Begründung:
AR routers support registration query center-based deployment, email-based deployment, and DHCP Option
148-based deployment. In registration query center deployment, the router obtains basic network connectivity, resolves or contacts Huawei's registration service, retrieves the address and port of iMaster NCE, and then initiates registration. Huawei identifies AR routers, firewalls, switches, and APs as applicable devices for this method.
Email-based deployment is a major SD-WAN ZTP method for AR routers operating as CPEs. An administrator creates the site and ZTP configuration on iMaster NCE and sends a deployment URL to the onsite engineer. After the URL is opened and the parameters are written to the router, the device connects to the WAN and automatically registers with the controller.
DHCP Option 148 can provide the controller's southbound IP address and port number to an IPv4 AR router, enabling automatic registration. Barcode scanning through the CloudCampus APP is specifically presented as an AP onboarding method, not an AR-router deployment method. Therefore, A, C, and D are correct.
41. Frage
Which of the following statements is true about an AP's transmit power?
Antwort: B
Begründung:
An AP's transmit power must be maintained within an appropriate range. Excessive power does not automatically improve service quality. A high-power AP can enlarge its interference domain, create co- channel or adjacent-channel interference, produce asymmetric uplink and downlink coverage, and cause sticky-client behavior because a station continues hearing an AP even when its weaker transmission cannot reliably reach that AP. Huawei states that high-power APs can interfere with adjacent APs and that radio calibration dynamically adjusts AP channels, power, and frequency bands to ensure coverage while minimizing interference.
Conversely, power that is too low creates coverage holes, weak received signal strength, low modulation rates, retransmissions, and roaming instability. When a new AP is added, neighboring APs may reduce their transmit power to limit interference. When an AP goes offline, neighboring APs may increase power to compensate for the missing coverage. The engineering objective is therefore neither maximum nor minimum power, but sufficient coverage with controlled overlap and minimum interference. Accordingly, option B is correct.
