NEW QUESTION # 53
What are the modes of the HSR RedBox?
Answer: A,B,C,D
Explanation:
An industrial RedBox can provide all four listed interconnection modes. In HSR-SAN mode, it connects a singly attached node that does not natively support High-availability Seamless Redundancy to an HSR network. The RedBox duplicates frames entering the HSR domain and removes duplicate frames before delivering traffic to the SAN.
HSR-PRP mode interconnects an HSR ring with a Parallel Redundancy Protocol network while preserving seamless redundancy. PRP-PRP mode couples two PRP network domains, while HSR-HSR mode connects separate HSR rings. Depending on the implementation, the HSR-HSR interconnection function may also be described as a QuadBox function because four HSR-facing ports can be involved.
The essential RedBox responsibilities are frame conversion, duplication, duplicate elimination, sequence- number handling, and prevention of unintended forwarding loops between redundancy domains. HSR and PRP use compatible duplicate-identification principles, enabling controlled interconnection between these network types without introducing a single point of failure. RedBoxes also provide redundant connectivity for devices that have only one ordinary Ethernet interface.
NEW QUESTION # 54
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 # 55
Which 5G-Advanced capabilities does the AR5710-S8T1XWE-NRGL support?
Answer: A,B,C,D
Explanation:
The AR5710-S8T1XWE-NRGL supports all four listed 5G-Advanced capabilities. Support for 3GPP Release
16 enables enhanced 5G New Radio functions and provides the standards foundation for improved mobile- WAN capacity, reliability, and service performance.
Carrier aggregation combines multiple component carriers to increase available throughput. Downlink 3CC allows three component carriers to be aggregated for received traffic, while uplink 2CC combines two carriers for transmitted traffic. This is valuable for high-bandwidth branch access, video backhaul, and mobile private- network scenarios.
Support for eight APNs permits multiple logically separated mobile services or provider profiles to be configured. Different APNs can represent enterprise services, management traffic, production systems, backup connectivity, or isolated customer networks. Global-frequency-band support improves deployment flexibility across countries and carrier networks, subject to local spectrum regulation and the supported modem variant.
Huawei SD-WAN can use 5G as a primary, secondary, or bypass link and supports combinations such as dual
5G and 5G plus wired connectivity for service assurance. Therefore, NR Release 16, carrier aggregation, eight APNs, and global frequency bands are all supported.
NEW QUESTION # 56
Which of the following BGP NLRI address-family combinations is used to transmit SD-WAN tunnel encapsulation information?
Answer: D
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 # 57
Which of the following deployment modes are supported by AR routers?
Answer: A,B,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.
