NEW QUESTION # 21
In the energy-saving solution based on AI traffic prediction, IoT APs are recommended to operate in non- energy-saving mode by default.
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 # 22
Which of the following deployment modes are supported by AR routers?
Answer: B,C,D
Explanation:
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.
NEW QUESTION # 23
Which of the following BGP NLRI address-family combinations is used to transmit SD-WAN tunnel encapsulation information?
Answer: C
Explanation:
AFI 1 with SAFI 74 is the correct combination. In Multiprotocol BGP, the Address Family Identifier defines the basic network-layer address family, while the Subsequent Address Family Identifier specifies how the associated NLRI is interpreted. AFI 1 represents IPv4. SAFI 74 is assigned for SD-WAN capabilities and is used to distribute information required for SD-WAN edge discovery and tunnel establishment, including transport and encapsulation-related attributes.
The other combinations represent different forms of reachability information. AFI 1/SAFI 1 is ordinary IPv4 unicast NLRI. AFI 1/SAFI 2 represents IPv4 multicast reachability. AFI 25 represents Layer 2 VPN information, while SAFI 70 represents Ethernet VPN routes; that combination is associated with EVPN rather than the specific SD-WAN capability NLRI requested.
Huawei's architecture uses BGP-based control channels to exchange transport network port information, IPsec security-association information, and service routes. These parameters allow edge devices to determine peer endpoints and create GRE or GRE-over-IPsec data channels after the relevant service routes trigger tunnel establishment.
NEW QUESTION # 24
Which of the following parameters is not mandatory for GRE configuration?
Answer: B
Explanation:
Enabling the GRE checksum is optional. A functional point-to-point GRE tunnel requires a tunnel interface, GRE as the tunnel protocol, and reachable source and destination tunnel endpoints. The source identifies the local interface or IP address used to construct the delivery header, while the destination identifies the remote GRE endpoint. Without these endpoint parameters, the device cannot correctly encapsulate and deliver packets to the peer.
The checksum field is controlled by the Checksum Present bit in the GRE header. When checksum processing is enabled, the sender includes a checksum covering the GRE header and payload, and the receiver verifies it.
This can provide additional corruption detection, but it increases processing and is not required for basic GRE operation. RFC 2784 explicitly labels the checksum field as optional and states that it is present only when the Checksum Present bit is set.
Huawei SD-WAN uses GRE or GRE over IPsec to establish data channels between edge devices. The essential tunnel and transport-network information is distributed through the control system, while optional GRE functions such as checksum validation may be enabled according to operational requirements.
NEW QUESTION # 25
Which of the following Wi-Fi 7 APs offers PCIe card-based IoT functions?
Answer: D
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.
