NEW QUESTION # 38
In the energy-saving solution based on AI traffic prediction, IoT APs are recommended to operate in non- energy-saving mode by default.
Answer: A
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 # 39
iMaster NCE-Campus can implement refined policy control over user permissions. Which of the following can be used as policy conditions?
Answer: A,B,C,D
Explanation:
All four options can be used as conditions by the iMaster NCE-Campus intelligent policy engine. Huawei describes this capability through a 5W1H-based policy model. "Who" represents the user identity, user group, or role. "Where" represents the access location, including the site, region, device group, device, SSID, or IP address. "How" represents the access mode, such as wired or wireless access and the authentication method used. "What" represents the terminal type or device attributes, including PCs and mobile operating systems.
The platform can combine these conditions rather than evaluating them independently. For example, a finance employee using a corporate laptop through wired 802.1X access at headquarters can receive different permissions from the same employee connecting through a personal mobile device at a branch. The authorization result can include a VLAN, ACL, security group, bandwidth limit, DSCP value, application policy, or URL-filtering rule.
This multidimensional evaluation enables context-aware, fine-grained access control. Therefore, A, B, C, and D are all correct.
NEW QUESTION # 40
In hierarchical networking, which of the following devices is used for communication between different areas?
Answer: A
Explanation:
A border device, or more precisely a device at a border site, provides communication between different areas in a hierarchical SD-WAN topology. The hierarchical model divides a large WAN into multiple areas. Each area can independently use a hub-spoke or full-mesh topology, while selected border sites connect the local area to a centralized backbone area.
When a non-border site receives a route originating in another area, the route's next-hop site ID is changed to the border site in its own area. The local border device then forwards traffic toward the border site in the destination area or toward an interconnected hub site. Ordinary edge devices provide connectivity for their own sites but do not automatically perform cross-area transit.
Huawei describes border sites as members of both the level-2 area network and the level-1 backbone network.
These sites collectively implement interconnection between areas. Huawei further explains that inter-area routes point to border sites and recommends two border sites operating in active/standby mode for reliability.
Therefore, the correct answer is B.
NEW QUESTION # 41
Which of the following statements is false about GRE over IPsec?
Answer: A
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
NEW QUESTION # 42
Which experience-assurance technologies does Huawei SD-WAN provide?
Answer: A,B,C,D
Explanation:
Huawei SD-WAN provides all four technologies. Per-flow load balancing distributes separate application flows among multiple links that have the same priority and satisfy the required SLA. Per-packet load balancing can transmit packets from one flow across multiple eligible links, improving aggregate bandwidth utilization for large file transfers, backups, and replication.
Multi-fed and selective receiving duplicates critical traffic across different links. The receiving device selects valid packets, removes duplicates, and preserves packet order. Packet loss or failure on one path therefore does not interrupt the service, enabling zero-millisecond link switchover in applicable deployments.
A-FEC dynamically generates redundant packets and adjusts the redundancy ratio according to measured packet loss. The receiving device reconstructs lost packets, reducing video freezing and voice-quality deterioration. Huawei describes both adaptive FEC and multi-fed selective receiving as WAN-optimization mechanisms for key traffic.
Intelligent traffic steering selects links according to application identity, quality, bandwidth, priority, and load.
Therefore, A, B, C, and D are all correct.
