NEW QUESTION # 51
Intelligent policy recommendation can achieve network-level load balancing.
Answer: A
Explanation:
The statement is true. Intelligent policy recommendation does not consider only the traffic load of an individual interface or device. iMaster NCE-Campus obtains network topology, application, link-quality, bandwidth-utilization, and traffic-distribution information from multiple devices. It can then recommend or orchestrate policies that distribute traffic across the network's available paths and resources.
For example, when multiple WAN links have the same priority and satisfy an application's SLA requirements, per-flow load balancing can distribute different application flows among those links.
Bandwidth-proportional balancing can also account for differences in link capacity, preventing a lower- bandwidth link from being overloaded. Huawei explains that load-balancing-based traffic steering can fully utilize multiple links and distribute flows across links meeting the required SLA.
Because iMaster NCE-Campus centrally manages CPEs and uniformly orchestrates service intent across the overlay network, recommendations can be evaluated from a network-wide perspective instead of through isolated local decisions. Therefore, intelligent policy recommendation can implement network-level load balancing.
NEW QUESTION # 52
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
Answer: C,D
Explanation:
Huawei switches' unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.
Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.
A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.
Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.
NEW QUESTION # 53
The CNN-based application identification technology can identify both known and unknown applications.
Answer: A
Explanation:
The statement is true in the context of Huawei's AI-assisted application-identification architecture.
Conventional identification depends mainly on predefined signatures, fixed destination addresses, port numbers, protocol fields, DNS correlation, or deep packet inspection. Huawei's standard SD-WAN process uses Service Awareness and First-Packet Identification signature databases to identify and group application traffic. These mechanisms are effective for known applications but become less reliable when traffic is encrypted, applications change versions, or previously unseen applications appear.
A CNN-based classifier learns multidimensional traffic characteristics such as packet-length sequences, timing, direction, and flow behavior. It can classify traffic matching learned application patterns and, when implemented with open-set detection, recognize flows outside known classes as unknown or zero-day applications. Commercial-grade deep-learning traffic classification research demonstrates identification of known encrypted applications together with the handling of unknown zero-day applications.
This does not mean the system automatically assigns an exact commercial name to every unseen application.
It detects that the traffic does not match established classes so that it can be investigated, labelled, and incorporated into later model updates. Therefore, the statement is True.
NEW QUESTION # 54
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.
NEW QUESTION # 55
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.
